Calculate both minute ventilation and alveolar ventilationgiven the following:respiratory rate = 12 breaths per minutetidal volume = 500 mL per breathphysiologic dead space = 150 mL per breath
Describe the ventilatory response to constant load, steady-state exercise. What happens to ventilation if exercise is prolonged and performed in a hot environment?
Ventilation disorders have a significant effect on the volume of air entering the lungs and its availability for gas exchange. Explain the association between decreased ventilation and pulmonary hypoxic vasoconstriction. Link your understanding of this physiological phenomenon to pulmonary hypertension and cor pulmonale in relation to chronic obstructive pulmonary disease (COPD).

Increase During normal resting conditions, arterial Pco2 is 40 mm Hg and minute ventilation is approximately 6.5 L/min. If the arterial Pco2 increased by 4 mm Hg. to what approximate value would minute ventilation increase? [Select] During normal resting conditions, arterial Poz is 100 mm Hg and minute ventilation is approximately 6.5 L/min.

- Respiratory epithelial cells are involved in mucus maintenance within the airway. Explain theroles of pumps, channels, and carriers in this process – emphasize CFTR’s role in chloridepassage, and how chloride triggers water movement which maintains the mucus fluidity in theairway.arrow_forwardHow will changes in arterial Po2 impact ventilation? Select the one most accurate response. Small changes in arterial Po2 will result in fine changes to VÊ in order to maintain relatively stable arterial Po2. O Arterial Po2 will not affect ventilation unless it drops below 60mmHg. O₂ cannot cross the blood/brain barrier, thus cannot interact with central chemoreceptors to have an impact on ventilation. O Breathing 100% O2 at atmospheric pressure will greatly reduce the urge to breathe.arrow_forwardDuring quiet breathing ventilation and perfusion both vary from the top to the bottom of the lungs when the body is upright. Discuss the reasons for these differences in their effect on the ventilation perfusion ratio.arrow_forward
