Arterial Blood Gas (ABG) Analysis and Interpretation questions with correct answers

Atmosphere - Answer Mostly N2 (78%), Some O2 (21%), and a little C02 (.03%). Partial pressures correspond to size of percentage. Gas Pressures - Answer Dalton's law. Each of these pressures is independent. If gas exerts a pressure in the atmosphere, it exerts a pressure in your body. Gas diffusion occurs based on... - Answer The pressure exerted, aka the pressure gradient Inspired Gas Pressure - Answer Inspired air undergoes warming and humidification. Pressure steadily goes down as it moves down towards your lungs because the cells in our body need a lower pressure. Water vapor pressure - Answer 47 mmHg. Pressure goes up with fever, but down with hypothermia. A-C (arterial-capillary) membrane - Answer Oxygen crosses the membrane and has two choices: combines with hemoglobin, or dissolve into the blood plasma. Blood travels around the body where oxygen is off-loaded to the tissues. % of O2 that combines with hemoglobin - Answer 97% % of O2 that dissolves into blood plasma - Answer 3% CO2 and the A-C membrane - Answer Carbon dioxide is produced in the body's tissues, it enters the blood and is carried in plasma and
