The ventilator will use the exhaled tidal volume measured at the end of that breath's expiratory phase to calculate the pressure of the next breath. If the exhaled tidal volume is lower than the software threshold, the next breath will be delivered at a higher pressure, and if the exhaled tidal volume is higher than the software threshold, the ...
[2] [3] The use of artificial ventilation can be traced back to the seventeenth century. There are three ways of exchanging gases in the body: manual methods, mechanical ventilation, and neurostimulation. [4] Here are some key words used throughout the article. The process of forcing air into and out of the lungs is known as ventilation.
Modes of mechanical ventilation are one of the most important aspects of the usage of mechanical ventilation.The mode refers to the method of inspiratory support. In general, mode selection is based on clinician familiarity and institutional preferences, since there is a paucity of evidence indicating that the mode affects clinical outcome.
These include current availability, [17] [18] the challenge of making more and lower cost ventilators, effectiveness, [19] functional design, safety, [20] [21] portability, [22] suitability for infants, [23] assignment to treat other illnesses, and operator training. [24] Deploying the best possible mix of ventilators can save the most lives.

Non-invasive ventilation (NIV) is the use of breathing support administered through a face mask, nasal mask, or a helmet.Air, usually with added oxygen, is given through the mask under positive pressure; generally the amount of pressure is alternated depending on whether someone is breathing in or out.
Airway pressure release ventilation (APRV) is a pressure control mode of mechanical ventilation that utilizes an inverse ratio ventilation strategy. APRV is an applied continuous positive airway pressure (CPAP) that at a set timed interval releases the applied pressure. Depending on the ventilator manufacturer, it may be referred to as BiVent.
High-frequency ventilation (HFV) is a type of mechanical ventilation which utilizes a respiratory rate greater than four times the normal value [1] (>150 (V f) breaths per minute) and very small tidal volumes.
