WebPulmonary ventilation is the act of breathing, which can be described as the movement of air into and out of the lungs. The major mechanisms that drive pulmonary ventilation are … 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. Fish and birds have unidirectional respiration.

"WebWeak patients may draw small tidal volumes on these extra breaths while strong patients may take in larger tidal volumes. Pressure control ventilation is quite different than either volume targeted AC or SIMV. In this mode, the clinician sets the peak inflation pressure and respiratory rate but does not specify the tidal volume. " - How does tidal ventilation work in humans

WebTidal Volume. Tidal volume is a measure of the amount of air a person inhales during a normal breath. Traditional preset tidal volumes higher than 10 ml/kg have been proved to be associated with increased risk of pulmonary barotrauma and should be avoided. High tidal volumes also decrease venous return and reduce cardiac output.
