The main driver of normal quiet ventilation is: Select one: O a. the H* concentration in the arterial blood, which is monitored by central chemoreceptors O b. the PO2 of the arterial blood, which is monitored by central chemoreceptors O c. the PO2 of the arterial blood, which is monitored by peripheral chemoreceptors O d. the H* concentration in the CSF, which is monitored by central chemoreceptors O e. the PCO2 of the arterial blood, which is monitored by peripheral chemoreceptors

Describe the effects of Increasing frequency vs tidal volume on minute ventilation and alveolar ventilation. I'm confused about what type of effects it will cause.
You want to calculate a patient's Inspiratory Capacity (IC). You already know that their Tidal Volume (TV) is 400mL. What volume or capacity would be the best thing to measure so you can best calculate IC? 1-Vital Capacity (VC) 2-Expiratory Reserve Volume (IRV) 3-Total Lung Capacity (TLC) 4-Inspiratory Reserve Volume (IRV)
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 examples
1) During alveolar HYPERventilation, levels of blood CO2 drop while blood O2 is elevated. What reflexive responses will this stimulate from the CPG? a) Increased DRG and VRG activity in the medulla, stimulating I and E motor neurons. b) Decreased DRG and VRG activity in the medulla, stimulating I and E motor neurons. c) Decreased DRG and VRG activity in the medulla, inhibiting I and E motor neurons. d) Increased DRG and VRG activity in the medulla, inhibiting I and E motor neurons.
