Increases oxygenation via alveolar recruitment.Positive pressure applied during exhalation via resistor in exhalation port.f may be lower than respiratory rate if breaths are patient triggered.Target should be lung protective: goal of less than equal to 6 cc/Kg.Fraction of inspired air that is oxygen.The following are the various variables on a ventilator: FiO2 Tailoring the ventilator settings can help achieve specific goals, for example, to improve oxygenation, option include increasing the FiO2 and PEEP and to improve ventilation, the tidal volume ( Vt), inspiratory pressure and respiratory rate (f) may be increased (this follows the basic principle of minute ventilation = Tidal volume x respiratory rate). The variables include fraction of inspired oxygen ( FiO2), tidal volume (Vt), respiratory rate (f), positive end expiratory pressure ( PEEP), inspiratory time, inspiratory flow rate, peak inspiratory pressure (PIP) and plateau pressure (Pplateau). They can be adjusted according to the clinical condition of the patient and to achieve specific goals of management. Ventilator variables modulate the oxygenation achieved.
