pH and proteinionized calcium is pH dependent; ph will increase if CO2 is lostCa will increase with increased protein

249
Q

3 things that regulate calcium/increase/decrease

A

VitD/PTH: increase Ca-VitD increases GI absorption of Ca-low Ca will stimulate PTH productionCalcitonin: decrease Ca-inhibits bone reabsorption

250
Q

Hypocalcemia causes

A

Tetany (decreased Ca,Mg)VitD def, hypoPTHhypo mag, albuminNormally, the parathyroid glands release a hormone that increases blood calcium levels when they are low. Magnesium is required for the production and release of parathyroid hormone, so when magnesium is too low, insufficient parathyroid hormone is produced and blood calcium levels are also reduced (hypocalcemia).
