Mary has a body mass of 64.5 kg and a predictied vital capacity of 4.8 L. A pulmonary function test at her doctors office revealed the following.  TLC is 5.2 L       TV is 0.5 L IRV is 1.5 L FEV1.0  is 2.4 L FVC is 3.4 L   Question 1. What is Marys Expiratory reserve volume (in L) ? Answer should include 1 decimal point.  Question 2: Marys results are consistent with a) obstructive pulmonary disorder b) restrictive pulmonary disorder c)  normal ventilatory function d)  both a and b

A soccer coach is seeking your advice about using a tank of oxygen on the sidelines so players might breathe from it during time outs or when they come off the field. Provide 3 mechanisms to explain/justify your answer to the coach. Consider the following in your answer. 98% O2 Hb saturation is achieved with each breath. The other way for oxygen to be carried to muscle would be dissolved in blood. This is minimal and still doesn’t affect Hb saturation Pulmonary ventilation is not considered to limit aerobic capacity A higher breathing rate actually helps to eliminate CO2 and therefore raise pH CO2 transport in blood also involves buffering H+ forming bicarbonate HCO3. On exhalation the H disassociates and forms water – again helping to maintain pH
