In the VA, sodium phosphate/sodium biphosphate enema is available for use in bowel preparation prior to a procedure or for the management of constipation. Our original studies have been referenced on 600+ medical publications including The Lancet, Mayo Clinic Proceedings, and Nature. Increased serum phosphate concentration and increased area under the curve of serum phosphate were associated with increased enema retention time. This decision is based on the presence of symptoms, the degree of hyponatremia, whether the condition is acute (arbitrarily defined as a duration of less than 48 hours) or chronic, and the presence of any degree of hypotension. 2012 Feb 13;172(3):263-5. doi: 10.1001/archinternmed.2011.694. If you use this eHealthMe study on publication, please acknowledge it with a citation: study title, URL, accessed date. Hyponatremia with a high plasma osmolality is caused by hyperglycemia, while a normal plasma osmolality indicates pseudohyponatremia or the post-transurethral prostatic resection syndrome. . in free water intake in the setting of the kidneys' diminished ability to. The most common and clinically most relevant electrolyte imbalancesconcern potassium, calcium and magnesium. Phosphate 1.4 2.5-4.5 mg/dL Magnesium 1.9 1.6-2.6 mg/dL Fatal hyperphosphatemia following Fleet Phospo-Soda in a patient with colonic ileus. Sodium is an electrolyte, and it helps regulate the amount of water that's in and around your cells. Bookshelf Medications and drugs that cause hyponatremia are listed in Table 1.2026 Some of the more common causes of medication-induced hyponatremia are diuretics20 and selective serotonin reuptake inhibitors (SSRIs).27 Most of the medications cause SIADH, resulting in euvolemic hyponatremia. Plasma osmolality testing places the patient into one of three categories, normal, high, or low plasma osmolality, while urinary sodium concentration testing is used to refine the diagnosis in patients who have a low plasma osmolality. The levels of electrolytes in your body can become too low or too high. and transmitted securely. Ventricular tachycardia, ventricular fibrillation and torsade de pointes. Hypertonic saline is usually reserved for severe hyponatremia (sodium < 115 meq/L). government site. PMC Urinary sodium concentration helps to differentiate between hyponatremia secondary to hypovolemia and syndrome of inappropriate antidiuretic hormone secretion (SIADH). Unable to load your collection due to an error, Unable to load your delegates due to an error. HYPONATREMIA IS DILUTED SERUM SODIUM Hyponatremia is defined as any plasma sodium concentration lower than <135 mmol/L. Hyponatremia can be seen in patients with. Therapeutic. MeSH You can discuss the study with your doctor, to ensure that all drug risks and benefits are fully discussed and understood. In severe cases, the maximum sodium increase within . The use of the eHealthMe site and its content is at your own risk. Hypermagnesemia is rare but severe hypermagnesemia may cause atrioventricular and intraventricular conduction disturbances, which may culminate in third-degree (Complete) AV block or asystole. Please enable it to take advantage of the complete set of features! Hyponatremia is diagnosed when the serum sodium concentration is less than 135mEq/L. It is created by eHealthMe based on reports of 145 people who have side effects while taking Sodium phosphates from the FDA, and is updated regularly. The pathophysiology of hyponatremia will be discussed later in this article. Oral phosphate can also be administered in tablets of sodium or potassium phosphate at doses of 2.5-3.5 g daily. Transient hyperphosphatemia following the use of sodium phosphates enemas correlates with retention time but not with dose. This trial sought to evaluate changes in the metabolic and hemodynamic parameters following the administration of one of two standard sodium phosphates enemas. Fortunately, in most cases, stopping the offending agent is sufficient to cause spontaneous resolution of the electrolyte imbalance. Renal disorders that cause hyponatremia include sodium-losing nephropathy from chronic renal disease (e.g., polycystic kidney, chronic pyelonephritis) and the hyponatremic hypertensive syndrome that frequently occurs in patients with renal ischemia (e.g., renal artery stenosis or occlusion).17 The combinations of hypertension plus hypokalemia (renal artery stenosis) or hyperkalemia (renal failure) are useful clues to this syndrome. Without treatment, it can lead to many issues, such as seizures, osteoporosis, and brain swelling. Hyponatremia is an electrolyte imbalance causing low blood sodium levels. In most cases, hyponatremia results when the elimination of total body water decreases. A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference. The serum sodium concentration is usually above 120meq/L. Assessment and decision-making should be based on the corrected serum sodium (corrected sodium = measured sodium . potassium, chloride, phosphate, and magnesium are all electrolytes. When the body's balance of electrolytes becomes unstable, the person suffers from hyponatremia. Would you like email updates of new search results? Acute hyperphosphatemia caused by sodium phosphate enema in a patient with liver dysfunction and chronic renal failure. Hypomagnesemia may also predispose to supraventricular and ventricular tachyarrhythmias. [ 1 ] Potassium substitution may be the etiology. These are real scientific discoveries about the nature of the human body, which can be invaluable to physicians taking care of patients. The 2020-2025 Dietary Guidelines for Americans recommend that Americans consume less than 2,300 milligrams (mg) of sodium each day as part of a healthy eating pattern. High sweat loss and fluid replacement presents complex systemic issues resulting in fluid retention more than sodium retention. Patients with this condition have normal water-load excretion and intact urine-diluting ability after an oral water-loading test. Sodium concentrations can also be affected by epinephrine, which stimulates renin release and sodium absorption. P-wave amplitude, P-wave duration and PR interval may all increase. Gastrointestinal problems are common adverse reactions to sodium phosphate, including gassiness, nausea, stomach upset, cramps and vomiting 2 3. Hyponatremia occurs when the concentration of sodium in your blood is abnormally low. 1993 Jun;88(6):929-32. Acute severe hyponatremia (i.e., less than 125 mmol per L) usually is associated with neurologic symptoms such as seizures and should be treated urgently because of the high risk of cerebral edema and hyponatremic encephalopathy.32 The initial correction rate with hypertonic saline should not exceed 1 to 2 mmol per L per hour, and normo/hypernatremia should be avoided in the first 48 hours.3335. Plasma and urine osmolality. Monosodium or disodium phosphate enemas are used for the treatment of acute and chronic constipation, and also for colon cleaning as preparation for endoscopic and surgical procedures, in both children and adults. The patient then should be classified into one of the following categories: hypervolemic (edematous), hypovolemic (volume depleted), or euvolemic. To avoid phosphorus intoxication, infuse solutions containing sodium phosphate slowly. See permissionsforcopyrightquestions and/or permission requests. You get them from the foods you eat and the fluids you drink. . generic drugs) are not considered. Loop diuretics are useful in managing edematous hyponatremic states and chronic SIADH. Return to One-Minute Consult Index. This is possible because there is a correlation between the severity of electrolyte imbalanceand the visible ECG changes. What is the most common electrolyte imbalance? 1. This calculator targets a level of 120 or 125 meq/L and determines the rate necessary to increase the serum sodium at 0.5 meq/L/hr. Your doctor may recommend IV sodium solution to slowly raise the sodium levels in your blood. To avoid central pontine myelinolysis, sodium should not be corrected faster than 0.5 mmol/L/hr unless patient is seriously symptomatic. These disorders usually are obvious from the clinical history and physical examination alone. In patients with chronic hyponatremia, overzealous and rapid correction should be avoided because it can lead to central pontine myelinolysis.9,10 In central pontine myelinolysis, neurologic symptoms usually occur one to six days after correction and often are irreversible.19 In most cases of chronic asymptomatic hyponatremia, removing the underlying cause of the hyponatremia suffices.9 Otherwise, fluid restriction (less than 1 to 1.5 L per day) is the mainstay of treatment and the preferred mode of treatment for mild to moderate SIADH.20 The combination of loop diuretics with a high-sodium diet may be required to achieve an adequate response in patients with chronic SIADH. Hypervolemic hyponatremia may be caused by congestive heart failure, liver cirrhosis, and renal disease. Most patients have chronic hyponatremia. Patients with low plasma osmolality (less than 280 mOsm per kg of water) can be hypovolemic or euvolemic. 2012 Sep 28;18(36):4994-5013. doi: 10.3748/wjg.v18.i36.4994. Patients with left ventricular hypertrophy may instead display normalization of secondary T-wave inversions (lead V5, V6, aVL, I). Other causes of hypercalcemia should be borne in mind Less than 1% of all patients are in this. Finally, U-waves emerge. This is certainlyalarming because sine wave pattern usually precedes ventricular fibrillation. Decreased absorption of . Does CHF cause low sodium? Sodium Phosphate Intravenous What Conditions does Sodium Phosphate Intravenous Treat? The parathyroid gland may be functioning autonomously, independent of ambient calcium level. Fatalities and severe metabolic disorders associated with the use of sodium phosphate enemas: a single center's experience. 10 The patient's denial of drinking excessive water also ruled out psychogenic polydipsia. Knowing which foods are the biggest contributors to sodium in your diet is an important step in reducing daily sodium intake to a healthy level. Patients with DKA present with a relative or total body deficiency of sodium, potassium, phosphate, and magnesium. Patients with extra-renal sodium loss have a low urinary sodium concentration (less than 30 mmol per L) as the body attempts to conserve sodium. Symptoms do not usually appear until the plasma sodium level drops below 120 mEq per L (120 mmol per L) and usually are nonspecific (e.g., headache, lethargy, nausea).11 In cases of severe hyponatremia, neurologic and gastrointestinal symptoms predominate.3 The risk of seizures and coma increases as the sodium level decreases. The normal blood sodium level is 135 to 145 milliequivalents/liter (mEq/L). Hyponatremia is a medical term used to describe deficiency of sodium. Hyponatremia is a serious electrolyte problem, with signifi-cant . Use of this site constitutes acceptance of eHealthMe.com's terms of service and privacy policy. Sodium Phosphates Injection, USP, 3 mmol/mL (millimoles/mL), is a sterile, nonpyrogenic, concentrated solution containing a mixture of monobasic sodium phosphate and dibasic sodium phosphate in Water for Injection. In psychiatric patients, the cause of hyponatremia is most commonly secondary to syndrome of inappropriate antidiuretic hormone secretion (SIADH) from psychotropics medications including antidepressants and antipsychotics . It will also discuss the symptoms, causes, and risk factors of the condition. Hyponatremia is a common disorder in patients with either acute or chronic heart failure, caused mainly by impaired water excretion instead of sodium depletion. Na+ 130 for contusion and SAH with GCS of 8/15 (Severe TBI). Pneumonia and empyema are well-known pulmonary causes, with legionnaires disease being a classic example.30 Another pulmonary cause is bronchogenic carcinoma and, in particular, small-cell carcinoma, which is also the most common cause of ectopic antidiuretic hormone secretion.31 Drug-induced SIADH is relatively common. Copyright 2022 American Academy of Family Physicians. Hyperglycemia results in factitious hyponatremia but measured Na can be used to calculate the initial anion gap . Approximately 3% of all patients are in this category. The treatment of hyponatremia can be divided into two steps. IMPORTANT This dosing tool is intended to assist with calculation, not to provide comprehensive or definitive drug information. The phase IV clinical study analyzes which people take Sodium phosphates and have Hyponatremia. Sodium phosphate, dibasic | H3Na2O5P | CID 61488 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological . During hyponatremia . Among them, 3 people (2.07%) have Hyponatremia. If the hypokalemia is severe, the U-wave may become larger than the T-wave. Hyponatremia is the clinical term given to a condition in which a dog is suffering from low concentrations of serum sodium in the blood. Sodium phosphate (NaP) agents were introduced to provide a gentler alternative to polyethylene glycol (PEG) bowel preparations, which require patients to drink up to 4 liters of fluid over a few hours. Causes include severe burns and gastrointestinal losses from vomiting or diarrhea. In patients with chronic hyponatremia, fluid restriction is the mainstay of treatment, with demeclocycline therapy reserved for use in persistent cases. Arginine vasopressin receptor antagonists may be useful in patients with chronic hyponatremia. Federal government websites often end in .gov or .mil. And there are many different causes, such as changes in kidney function, blood pressure medicines, or conditions like heart or liver failure. This requires a stay in the hospital for frequent monitoring of sodium levels as too rapid of a correction is dangerous. Hypokalemia potentiates the pro-arrhythmic effects of digoxin. WARNING: Please DO NOT STOP MEDICATIONS without first consulting a physician since doing so could be hazardous to your health. Definition Overzealous correction of chronic hyponatremia can lead to central pontine myelinolysis. As a component of the extracellular fluid (fluids outside of the cells), sodium is the most abundant positive charged atom in the body. The most . Beloosesky Y, Grinblat J, Weiss A, Grosman B, Gafter U, Chagnac A. Arch Intern Med. It's estimated that at least half of people with hypertension have. The reset osmostat syndrome occurs when the threshold for antidiuretic hormone secretion is reset downward. In dilutional hyponatremia, the plasma osmolality is lower than normal. Twenty-five participants were given one Enema Casen, whereas 20 participants received one Fleet Enema. Why Use Sex Female Male Age range Child Adult Weight lbs Sodium mEq/L Desired sodium mEq/L Result: Please fill out required fields. It is caused by the presence of glucose molecules that exert an osmotic force and draw water from the intracellular compartment into the plasma, with a diluting effect. Kosseifi S, Nassour D, Byrd RP Jr, Roy TM. Hyponatremia (abnormally low level of sodium in the blood; associated with dehydration) is found to be associated with 2,620 drugs and 1,400 conditions by eHealthMe. A healthy sodium level is between 135 and 145 mmol/l and a person is considered to be hyponatremic if the level falls to below 135 mmol/l. It helps maintain fluid balance and it also plays a key role in nerve and muscle function. Loop diuretics can be used in severe cases.38 Hemodialysis is an alternative in patients with renal impairment. Pearl 1 - General Approach. This effect is transient (for example, an increase in sodium concentration of between 5-10 mEq/L was seen in goats 60 minutes after injection of 2 mg epinephrine and sodium normalized by 90 minutes ( Abdelatif and Abdalla et al 2012 ). Figure 113 shows an algorithm for the assessment of hyponatremia.

Medications. SIADH is an important cause of hyponatremia that occurs when normal bodily control of antidiuretic hormone secretion is lost and antidiuretic hormone is secreted independently of the bodys need to conserve water. Refer to. The sodium phosphate chemical formula is Na3PO4 and it has a molecular weight of 163.94 g/mol. Insulin deficiency, Addisons disease and digoxin intoxication may also cause hyperkalemia. Clipboard, Search History, and several other advanced features are temporarily unavailable. Because of their prevalence and importance, SIADH and drugs deserve special mention, and the author will elaborate on these causes later in the article. Electrolyte Section Electrolytes and related calculators / tables Reference library home Calculators / Tools The hyponatremia is considered severe if this level. This increase in total body water is greater than the total body sodium level, resulting in edema. Calculates recommended fluid type, rate, and volume to correct hyponatremia slowly (or more rapidly if seizing). Hyponatremia can be classified according to the volume status of the patient as hypovolemic, hypervolemic, or euvolemic. Therefore the ECG may be used to estimate the severity of hyperkalemia. The patient with CKD is brought to the emergency department with Kussmaul respirations. HHS Vulnerability Disclosure, Help In either case, the serum levels of thyroid-stimulating hormone (TSH), cortisol, and adrenocorticotropic hormone (ACTH) should be measured, because hypothyroidism and hypoadrenalism can coexist as a polyendocrine deficiency disorder (i.e., Schmidts syndrome). Join our newsletter and get our free ECG Pocket Guide! Sodium picosulfate ( INN, also known as sodium picosulphate) is a contact stimulant laxative used as a treatment for constipation or to prepare the large bowel before colonoscopy or surgery. Assessing the Clinical and Laboratory Parameters This is a potentially dangerous range of mineral metabolism abnormalities to have. Each participant had a bowel movement within 10 minutes of receiving his enema. The post-transurethral prostatic resection syndrome consists of hyponatremia with possible neurologic deficits and cardiorespiratory compromise. Electrolyte disorders following oral sodium phosphate administration for bowel cleansing in elderly patients. These changes were correlated with scientific literature reports of hyperphosphatemia following phosphate enema use. Sodium Deficit in Hyponatremia - MDCalc Sodium Deficit in Hyponatremia Calculates sodium quantity missing in hyponatremia. Sodium content: 92mg (4 mEq)/mL Hypophosphatemia The dose and administration IV infusion rate for sodium phosphates are dependent upon individual needs of the patient Phosphorous serum level. 1999 Sep;21(5):541-4. doi: 10.3109/08860229909045194. It is sold under the trade names Sodipic Picofast, Laxoberal, Laxoberon, [1] Purg-Odan, Picolax, Guttalax, Namilax, Pico-Salax, [2] PicoPrep, [3] and . Hypomagnesemia may potentiate the pro-arrhythmic effect of digoxin. P-wave amplitude decreases. The ECG may be used to estimate the severityof electrolyte imbalances and to judge whether there is a risk of serious arrhythmias. Potassium plays a key role in both depolarization and repolarization, which is why potassium imbalancemay cause dramatic ECG changes. The development of clinical signs and symptoms also depends on the rapidity with which the plasma sodium level decreases. The https:// ensures that you are connecting to the This increase in total body water is greater than the total body sodium level, resulting in edema. Some causes, such as congestive heart failure or use of diuretics, are obvious. WARNINGS: Sodium Phosphates Injection, USP, 3 mM P/mL must be diluted and thoroughly mixed before use. c. Increased ammonia from bacterial breakdown of urea. The following ECG changes occur in chronological order as potassium levels decrease. Look below for a review of hyponatremia. Hyponatremia is decrease in serum sodium concentration < 136 mEq/L ( < 136 mmol/L) caused by an excess of water relative to solute. There is a rather strong correlationbetween plasma potassium level and ECG changes, as well as the risk of arrhythmia. between sodium intake and output. A more recent article on this topic is available, Ecstasy (3,4-methylenedioxymethamphetamine), Cerebral disorders (e.g., tumor, meningitis), Chest disorders (e.g., pneumonia, empyema). In all patients with hyponatremia, the cause should be identified and treated. If the hyperkalemia is very severe, the QRS complex may fuse with the T-wave and form a so-calledsine wave. Differentiating between hypovolemia and euvolemia may be clinically difficult, especially if the classic features of volume depletion such as postural hypotension and tachycardia are absent.14. Acute or symptomatic hyponatremia can lead to significant rates of morbidity and mortality.57 Mortality rates as high as 17.9 percent have been quoted, but rates this extreme usually occur in the context of hospitalized patients.8 Morbidity also can result from rapid correction of hyponatremia.9,10 Because there are many causes of hyponatremia and the treatment differs according to the cause, a logical and efficient approach to the evaluation and management of patients with hyponatremia is imperative. Hyponatremia in the presence of edema indicates increased total body sodium and water. Diagnosing hypothyroidism or mineralocorticoid deficiency (i.e., Addisons disease) as a cause of hyponatremia requires a high index of suspicion, because the clinical signs can be quite subtle. Causes of hyponatremia include dehydration , excessive free water intake (e.g., primary polydipsia ), and increased release of ADH causing reabsorption of free water in the kidneys (e.g., SIADH , CHF ). The solution is administered after dilution by the intravenous route as an electrolyte replenisher. Lengthened QT interval (torsade de pointes is uncommon), Shortened QRS duration (has no clinical significance), The earliest sign of hyperkalemia is the pointed T-waves. Ren Fail. Less common causes include acute intermittent porphyria, multiple sclerosis, and Guillain-Barr syndrome. Sodium Phosphates Solution Sodium Phosphates Solution - Uses, Side Effects, and More Generic Name(S): sodium phosphates View Free Coupon Uses Side Effects Precautions Interactions. Poor prognostic factors for severe hyponatremia in hospitalized patients include the presence of symptoms, sepsis, and respiratory failure. Despite their long availability, these products have not been fully characterized pharmacokinetically. Cortisol decreases glomerular filtration rate, and renal plasma flow from the kidneys thus increasing phosphate excretion, . Differentiating between euvolemia and hypovolemia can be clinically difficult, but a useful investigative aid is measurement of plasma osmolality. Das S, Bandyopadhyay S, Ramasamy A, Prabhu VV, Pachiappan S. The .gov means its official. All rights reserved. Another suggestive feature is the presence of hypouricemia caused by increased fractional excretion of urate.29 Common causes of SIADH are listed in Table 3. In the event of a rapid decrease, the patient can be symptomatic even with a plasma sodium level above 120 mEq per L. Poor prognostic factors for severe hyponatremia in hospitalized patients include the presence of symptoms, sepsis, and respiratory failure.12. Sodium bicarbonate and Hyponatremia - a phase IV clinical study of FDA data Summary: Hyponatremia is found among people who take Sodium bicarbonate, especially for people who are male, 60+ old, have been taking the drug for < 1 month. On March 26, 2013, the PBM VA Center for Medication Safety issued a National PBM Bulletin in response to a fatality in a patient administered several doses of sodium phosphate/sodium biphosphate Na+ 128 for diffusion axonal injury with GCS of 3/15, 8/15 (Severe TBI) in 2 patients. Hyponatremia occurs when your blood sodium level goes below 135 mEq/L. The condition is chronicbut stablehyponatremia.18 It can be caused by pregnancy, quadriplegia, malignancy, malnutrition, or any chronic debilitating disease. Sodium phosphate is contraindicated in diseases where high phosphorus or low calcium levels may be encountered, and in patients with hypernatremia. ST segment depression develops and may, along with T-wave inversions, simulate ischemia. The Enema Casen induced a greater mean AUC of serum sodium concentration than did the Fleet Enema. Plasma osmolality, a major determinant of total body water homeostasis, is measured by the number of solute particles present in 1 kg of plasma. First, the physician must decide whether immediate treatment is required. Sodium. Hyponatremia is a significant clinical problem: . Treatment of Schmidts syndrome involves steroid replacement before thyroxine T4 therapy to avoid precipitating an addisonian crisis. Brain adapts itself to hyponatremia by generation of idiogenic osmoles. Phosphate Dosing -Hypophosphatemia Phosphate Dosing Patient's weight: Current phosphate level : Patient is: Phosphate supplementation References: Looking for additional info regarding electrolytes? Acute water overload, which usually is obvious from the patients history, occurs in patients who have been hydrated rapidly with hypotonic fluids, as well as in psychiatric patients with psychogenic overdrinking. In hyponatremia, one or more factors ranging from an underlying medical condition to drinking too much water cause the sodium in your body to become diluted. Hyponatremia generally is defined as a plasma sodium level of less than 135 mEq per L (135 mmol per L).1,2 This electrolyte imbalance is encountered commonly in hospital and ambulatory settings.3 The results of one prevalence study4 in a nursing home population demonstrated that 18 percent of the residents were in a hyponatremic state, and 53 percent had experienced at least one episode of hyponatremia in the previous 12 months. 2022 eHealthMe.com. With medical big data and proven AI algorithms, eHealthMe provides a platform for everyone to run phase IV clinical trials. Hyponatremia and ESRD. 30 Foods High in Sodium and What to Eat Instead Table salt, known chemically as sodium chloride, is made up of 40% sodium.

It is calculated in mmol per L by using this formula: Total body sodium is primarily extracellular, and any increase results in increased tonicity, which stimulates the thirst center and arginine vasopressin secretion. The site is secure. Previously mentioned ECG changes become more pronounced. Each enema contained 19.2 g of monobasic NaP and 7.2 g of dibasic NaP. The high levels of both calcium and phosphate increase the risk of ectopic calcification. intracellular phosphate/potassium deficit due to malnu-trition. With medical big data and AI algorithms, eHealthMe is running millions of phase IV trials and makes the results available to the public. Hyponatremia is reported only by a few people who take Sodium Phosphates. FOIA Blood pressure, pulse, and serum chemistries were evaluated at screening; baseline; and 10, 60, and 120 minutes after receiving the enema. Calcium Hypercalcemia Causes of hypercalcaemia. Intravenous replacement of phosphorous should be reserved for patients with severe (<1 mg/dl, 0.32 mmol/l) symptomatic hypophosphatemia until the serum phosphorous exceeds 1 mg/dl and the patient can be switched to oral therapy. This is a salt found both in hydrated and anhydrous salts among which anhydrous (water-free) sodium phosphate is more common in nature. 8600 Rockville Pike 2. Sodium Correction Rate in Hyponatremia and Hypernatremia Calculates recommended fluid type, rate, and volume to correct hyponatremia slowly (or more rapidly if seizing). Hypokalemia may also cause monomorphic ventricular tachycardia. The phenomenon of pseudohyponatremia is explained by the increased percentage of large molecular particles, such as proteins and fats in the serum, relative to sodium. [1, 8]. Excess renal sodium loss can be confirmed by finding a high urinary sodium concentration (more than 30 mmol per L). Primary hyperparathyroidism and malignancies cause 90% of all cases of hypercalcemia. Abnormal shift of phosphate into the cell - This may be caused by hyperventilation, respiratory alkalosis, hyperglycemia, and hypercalcemia.
