ventilator mechanics

Ventilator mechanics involve how a machine assists or takes over breathing by moving air in and out of the lungs. It works through two main processes: delivering precise amounts of air (tidal volume) at set rates (respiratory rate) and adjusting pressures to ensure the lungs expand properly without damage. The ventilator can control how much air enters (volume control) or how much pressure is used (pressure control). It also manages the timing of breaths and can synchronize with a person's natural breathing efforts. Overall, it supports gas exchange—bringing in oxygen and removing carbon dioxide—especially when the lungs can't do so adequately on their own.
