Table 1-Normal Breathing Run Description Mean O2 concentration (%) Co2-02 Tee alone CO2-02 Tee+ 15 cm PVC pipe CO2-O2 Tee +30 cm PVC pipe 16 16 2 3 15 82 Table 2-Deep Breathing Run Description Mean O2 concentration (%) CO2-O2 Tee alone CO2-02 Tee + 15 cm PVC pipe CO2-02 Tee +30 cm PVC pipe 2. 2 17 53 3 DATA ANALYSIS 1. The varying lengths of PVC pipe act to increase the volume of inhaled air that is not available for gas mixing and exchange- the so-called "dead space." Calculate the volume of air in the 15 and 30 em lengths of PVC pipes (ur 'h), respectively. To each value, add 30 mL to account for the volume of air present in the CO2-O2 Tee. Record your answers in the table below in the column labeled "Volume" (remember that cm3 mL). Add these volumes to your anatomical dead space (150 mL), and enter the total values into the table.

Explanation / Answer

Pipe length 15--> 15+ 30 --> 30 +150

45 --> 180 ml

Pipe length 30--> 30+30=60--> 30+150

60 --> 180ml
