Factors that may induce or sustain [2] hyperventilation include: physiological stress, anxiety or panic disorder, high altitude, head injury, stroke, respiratory disorders such as asthma, pneumonia, or hyperventilation syndrome, [5] cardiovascular problems such as pulmonary embolisms, anemia, an incorrectly calibrated medical respirator, [1] [3 ...
The diagnosis of respiratory alkalosis is done via test that measure the oxygen and carbon dioxide levels (in the blood), chest x-ray and a pulmonary function test of the individual. [ 1 ] The Davenport diagram is named after Horace W Davenport a teacher and physiologist which allows theoreticians and teachers to graphically describe acid base ...
[8] [6] Metabolic alkalosis can be caused by repeated vomiting, [2] resulting in a loss of hydrochloric acid in the stomach contents. Severe dehydration, and the consumption of alkali, [3] are other causes. It can also be caused by administration of diuretics [2] and endocrine disorders such as Cushing's syndrome.
Hypovolemia then leads to metabolic alkalosis (increase in blood pH) by stimulating bicarbonate reabsorption in order to maintain extracellular volume. [5] [10] In summary, the symptoms of alkalosis is the net result of over-consumption of absorbable alkali, hypercalcemia-induced hypovolemia, and impaired glomerular filtration rate. [5]
Diagnosis of contraction alkalosis is made by correlating laboratory data with clinical history and examination. Metabolic alkalosis in the presence of decreased effective circulatory volume, loop diuretic use, or other causes of intravascular depletion such as profound diarrhea should raise suspicion for contraction alkalosis as a likely etiology in the absence of other causes.
Acute hypocapnia causes hypocapnic alkalosis, which causes cerebral vasoconstriction leading to cerebral hypoxia, and this can cause transient dizziness, fainting, and anxiety. [3] A low partial pressure of carbon dioxide in the blood also causes alkalosis (because CO 2 is acidic in solution), leading to lowered plasma calcium ions ...
Hypocalcemia is a medical condition characterized by low calcium levels in the blood serum. [5] The normal range of blood calcium is typically between 2.1–2.6 mmol/L (8.8–10.7 mg/dL, 4.3–5.2 mEq/L), while levels less than 2.1 mmol/L are defined as hypocalcemic. [1] [3] [6] Mildly low levels that develop slowly often have no symptoms.
Metabolic alkalosis is an acid-base disorder in which the pH of tissue is elevated beyond the normal range (7.35–7.45). This is the result of decreased hydrogen ion concentration, leading to increased bicarbonate (HCO − 3), or alternatively a direct result of increased bicarbonate concentrations.
