Please use this formula Va=(Vt-Vd)×RR TV=Vt

Prior to begin training for a marathon, you have some lung function tests performed. Your measured tidal volume at rest is 550 mL, your dead space volume is 150 mL, and your resting breathing rate is 12 breaths per minute. On a treadmill, your tidal volume increases to 1150 mL and your breathing rate increases to 30 breaths per minute. What is your alveolar ventilation rate when you are on the treadmill? O 30 Liters/min O 4.8 Liters/min O 12 Liters/min O 34.5 Liters/min O 6.6 Liters/min

A 6-year-old child inhales a peanut while playing which lodged in his right bronchus. The part of the lung being ventilated by the right bronchus will be showing which of the following regarding V/Q situation. High V/Q rationormalLow V/Q ratioDead spacevasodilation

What are the mechanisms that affect ventilation at a high altitude? Why the change in ventilation is beneficial and how it can also be detrimental. What other factors operate at a high altitude to improve the oxygen delivery to the tissues?
