1.

the pco2 level in the expired air under normal condition is approximately 1 )49mm of hg 2) 100mm of hg 3) 32 mm of hg 4) 116 my of hg

Answer»

It is 49mm of Hg. The influence of CO2 storage in lung tissue and CERTAIN pathophysiologic conditions on the accuracy of these methods was systematically investigated with a COMPREHENSIVE multi-chamber computer simulation of the lung.


For normal levels of CO2 storage capacity, satisfactory estimates of arterial-venous O2 content difference are feasible for DIFFERENCES less than 8 volumes percent; with high levels of CO2 storage capacity, large errors can occur.
