Unformatted text preview: 2 8 Chapter 3 Start of End of capillary capillary l ’ ‘ l Alveolar—> ————— 02 (Normal) 02 (Abnormal) Partial pressure —‘l_ | _‘| O .25 .50 .75 Time in capillary (sec) Figure 3-2. Uptake of carbon monoxide, nitrous oxide, and 02 along the pul- monary capillary. Note that the blood partial pressure of nitrous oxide virtually reaches that of alveolar gas very early in the capillary so that the transfer of this gas is perfusion limited. By contrast, the partial pressure of carbon monoxide in the blood is almost unchanged so that its transfer is diffusion limited. 02 transfer can be perfusion limited or partly diffusion limited, depending on the conditions. ...
