WebMinute ventilation (or respiratory minute volume or minute volume) is the volume of gas inhaled (inhaled minute volume) or exhaled (exhaled minute volume) from a person's lungs per minute. It is an important parameter in respiratory medicine due to its relationship with blood carbon dioxide levels.

WebIn the vertebrate world, there are two major types of respiration: unidirectional and bidirectional (or tidal). In unidirectional ventilation, the medium (air or water) moves across tissues in one direction. This method is efficient because the medium is always fresh.
