In healthy humans, ventilation is tightly controlled by a system that is concerned with both the precise constancy of alveolar and arterial blood gases and acid–base status as well as with minimising the work and metabolic cost of each breath. Breathing must remain a largely involuntary act of which we are unaware.

The ventilation rate (V) refers to the volume of gas inhaled and exhaled from the lungs in a given time period, usually a minute. It can be calculated by multiplying the tidal volume (volume of air inhaled and exhaled in a single breath) by the respiratory rate. In an average man, the ventilation rate is roughly 6L/min. Ventilation is the movement of air in and out of the body. Minute ventilation (MV) is a product of tidal volume (TV) multiplied by rate (MV = TV × RR) Alveolar ventilation is the amount of oxygen delivered to the alveoli during one breath. Respiratory physiology is maintained by changing pressures within the chest.

Control of ventilation • 3. A survey 1. Gas exchange in the lungs Measurement of alveolar ventilation Alveolar ventilation is defined as a flow of respiratory gases through perfectly functioning (=exchanging gases) alveoli (it should be better called: „gas exchange Normal inspiration generates negative intrapleural pressure, which creates a pressure gradient between the atmosphere and the alveoli, resulting in air inflow. In mechanical ventilation, the pressure gradient results from increased (positive) pressure of the air source.

It can be calculated by multiplying the tidal volume (volume of air inhaled and exhaled in a single breath) by the respiratory rate. In an average man, the ventilation rate is roughly 6L/min. PAH is a significant contributor to right ventricular dysfunction. 22–24 The challenges to mechanical ventilation in patients with PAH are significant, as positive pressure ventilation can exert a destabilizing hemodynamic impact on an already stressed right heart.
