			==Common Features of a "standard" machine"==
			*a way of measuring and controlling the volume pumped and the breath rate to avoid volutrauma
			*monitoring for inspiratory pressure, respiratory rate (bpm), and inspiratory-to-expiratory time (I/E) ratio
			*for non-sedated patients, an "assist" mode that, instead of forcing air in at a fixed frequency, only increases the pressure when the patient inhales;
			*for ARDS, support for setting positive end-expiratory pressure (PEEP) to avoid alveoli collapse;[6][7]
			*humidification to avoid drying and cooling the alveoli
