A drop in phosphate in the bloodstream.
48
Hyperphosphatemia AC
An excess of phosphate in the blood that can be caused by tumor lysis syndrome, rhabdomyolysis, lactic acidosis, or diabetic ketoacidosis.
49
Acidosis AC
A condition that occurs when the pH of blood and/or extracellular fluid drops below the normal range, less than 7.35.
50
Metabolic Acidosis AC
A form of acidosis occurring when excess acid is produced, bicarbonate is lost, or the kidneys do not excrete enough acid.
51
Respiratory Acidosis AC
A form of acidosis resulting from slow breathing and retention of carbon dioxide in the blood.

Alkalosis AC
A condition that occurs when there is a relative excess or bicarbonate in the blood and/or extracellular fluid and the pH rises above the normal range, more than 7.45.
53
Metabolic Alkalosis AC
A form of alkalosis occurring when excess acid is excreted via the kidneys or acid is lost from the stomach.
54
