generation/initiation of process
*caused by a process which results in one or more of the following conditions...
→ net
loss of {{c1::hydrogen (H+)}} and {{c2::chloride (Cl-)}} ions via GI tract (e.g., vomiting, nasogastric drainage) or kidney (e.g., hyperaldosteronism)
→ {{c3::alkali}}
loading (usually
requires concomitant renal insufficiency)
→ disproportionate
loss of {{c2::chloride}} with increased
{{c4::HCO3-}}
absorption by
the kidney (diuretics, mineralocorticoid excess, idiopathic chloride-resistant
alkalosis which can occur with severe potassium depletion)
maintenance phase
*three causes of metabolic alkalosis...
- {{c6::chloride}} depletion: most common cause
- hypo{{c6::kalemia}}
- abnormally increased {{c5::mineralcorticoid/aldosterone}} activity
*reduced
effective blood volume is NOT another cause...not a standalone cause of (contraction) alkalosis
