Re: Gary Hall Sr. Test: 9% less drag riding on your bubbles [hugoagogo]
When the lungs are full, increased pressure in the chest decreases blood return to the heart and cardiac output. Deep inspirations (high tidal volume) and rapid expiration (increased pressure) are not optimal ventilation. There are a number of ventilator settings that demonstrate this relationship. In fact, individuals on a ventilator need to be sedated so that the don’t “fight” the optimal setting (volume and frequency) and decrease gas exchange (CO2 and O2) and cardiac output (delivery to and from the lungs and body). Sucking and blowing are bad! Expiration is relaxation and elastic recoil... not a muscular contraction.
