Document Summary

80 torr then you can enter a comatose: hypoxemia: low o2 in blood, hypercapnia: high co2 retention, hypocapnia: low co2 compared to normal blood levels. Alveolar gas composition & blood gas transport: lecture 7: each polypeptide chain (4 aa chains make up hb 2 alpha & 2 beta) is attached to a heme group which contains an iron atom. Increase po2 = increase o2 saturation (sao2: sao2 = o2 saturation (how much o2 is bound to the hb, 1g of hb binds to 1. 34ml of. No because they are still at normal arterial blood point (flat on curve) only administer when drop further onto shoulder curve. Alveolar gas composition & blood gas transport: lecture 7. P50: po2 at which sao2 is 50, changes in p50 (i. e. changes in po2) indicate if there is a shift in the position of the hbo2 dissociation curve to the left or right.
