ifl fullyl compensated,l checkl whetherl itl isl leaningl highl orl lowl tol determinel ifl itl isl acidosisl orl alkalosis
Q:l try: pHl =l 7.30 PaCO2l =l 50 HCO3-l =l 30
Answer:
l partiallyl compensatedl respiratoryl acidosis
1.l thel pHl isl 7.30.l Thisl isl lowerl thanl normal,l sol wel havel anl acidosis.
