The formula to determine minute ventilation is:
O VA - (Vd x f)
O fx Vt
O fx (Vt - Vd)
O None of these are correct
O (Vd - Vt) x f
Pulmonary ventilation (VE) is determined by two variables. What are they and what do
they represent?

- Although respiratory muscles are voluntary, you cannot hold your breath until you lose consciousness because your brain will force you to ventilate (= breathe) before then. Explain how the brain ‘knows’ when to stimulate ventilation. please help with examplesarrow_forwardMinute ventilation (Ve, L/min) is the result of tidal volume (TV, L/breath) and frequency (f, breaths/min) such that Ve = TV x f. The Ve which would result in the greatest alveolar ventilation would be: %3D O Ve = 5, TV =1.0 , f = 5 O Ve = 5, TV = 0.5, f = 10 O Ve = 5, TV = 0.25, f = 20arrow_forwardCalculate the respiratory rate (RR) and maximal voluntary ventilation (MVV) using the values provided in the table.arrow_forward

- Discuss the Respiratory quotientarrow_forwardMechanical ventilation is indicated when the patient's spontaneous ventilation is inadequate to sustain life by hooking the patient into a mechanical ventilator. It provides breathing support until lung function is restored, delivering warm (body temperature 37° C [98.6° F]), 100% humidified oxygen at FiO2 levels between 21% to 100%. 1.

Suppose the person exercises, so that tidal volume increases to 4000 mL, dead space increases to 300 mL due to dilation of the respiratory passageways, and respiratory rate increases to 24 breaths per minute. What is the alveolar ventilation then? How is the change in alveolar ventilation beneficial for doing exercise?arrow_forward
