Nitroprusside is a vasodilator agent that shares many features with nitroglycerin. One of these is the participation of nitric oxide in the vasodilator actions of the drug. It contains one nitrosyl group (NO), and this is released in the bloodstream as...

The universal goal of resuscitation is to maintain oxygen uptake (VO2) into the vital organs and thereby sustain aerobic metabolism. The determinants of oxygen uptake are identified in the equation shown below. VO2 = Q x Hb x 13 x (SaO2 - SvO2) The...

The total volume of body fluids represents 60% of lean body weight (or 600 mL/kg) in men and 50% of lean body weight (or 500 mL/kg) in women. The volume of whole blood is 6.0 to 6.6% of lean body weight (or 60 to 66 mL/kg), which means that only 11...
