A person has a VC of 4500ml, IRV of 2800ml and an ERV of 1000ml.What would there minute ventilation be if they had 15 breaths per minute? Minute ventilation MV= TV X breaths per minute

you  measure mr.johnson respirations as 16 breaths in 30 seconds what would you record

After finishing last in the gymnastics competition (they had to cut him free from the rings), it is now time for synchronised swimming. In order to be able to breathe under water, Marco has snuck in a balloon which he will breathe in and out of while submerged. Consider how the following parameters will change over time as he continues to re-breathe from the balloon. Ignore the pressure effects of the water on Marco and the balloon. Central chemoreceptor activity Minute ventilation Plasma pH Arterial PO2 [Choose ] ✓ [Choose ] Diameter of pulmonary arterioles Decrease No change Increase [Choose ] [Choose ]

Which is a more effective way to increase alveolar ventilation ? doubling tidal volume while maintaining normal breathing rate or doubling breathing rate while maintaining normal tidal volumes   PLEASE HELP PRACTICE QUESTION

While having a physical examination, a young male informed his doctor that at age 8 he has lobar pneumonia and pleurisy in his left lung. The physician decided to measure his VC. Describe the apparatus and method used for taking this measurement . Define the following terms used in the description of lung volumes. TV, IRV, ERV, RV, and VC.

While a subject was exercising vigorously the measurements in the Table were made. All measurements are referenced to BTP. Note that tidal volumewas 1000 ml (not 500 ml) and the breathing rate was 25 breaths/min. Whatwere the subject’s O2 consumption rate and CO2 production rate (ml gas atSTP per minute)?

Why do we use FEV1/FVC which is a measure of exhalation rate in pulmonary function testing instead of rate of inhalation?

List three ways the respiratory system of an individual might respond to overcome the challenge of hypoxia while travling at high altittude.

Given the following values: ERV=1700mL ERV+TAV= 2200 mL VC= 3000 mL 1) Calculate TAV and IRV. 2) If they have a breathing rate of 14 breaths/min, what is their minute ventilation? 3) If they have the normal dead space ventilation of 150 mL, what is their alveolar ventilation? (show dead space volume as part of the calculation). 4) If they start exercising and increase their breath volume to 1600 mL with 25 breaths per minute, what is their alveolar ventilation now?
