<unk>  ventilator<unk>  should be modified and tailored according to the clinical condition of the patient and specific goals of management. Selection of ventilatory mode, sensitivity at flow trigger mode, tidal volume, rate, inspiratory flow, positive end expiratory pressure (PEEP), pressure limit, inspiratory time and fraction of inspired oxygen (FiO2) should be made according to the underlying etiology of hypoxemia/hypercapnia. Other factors for example, age of the patient, weight and height also play an important role in deciding the<unk>  ventilatory<unk> . General rules that help physicians to choose the<unk><unk>  in a time-efficient manner include choosing a tidal volume of 12 mL per kg body weight delivered at a rate of 12 a minute (12-12 rule) in adults and adolescents. In infants and children without existing lung disease a tidal volume of 4-10 ml/kg may be delivered at a rate of 30-35 breaths per minute. With respiratory distress syndrome (RDS), a decreased tidal volume and increased respiratory rate sufficient to maintain pCO2 between 45-55. Allowing higher pCO2 (sometimes called permissive hypercapnia) may help prevent ventilator induced lung injury. Ventilator triggered breaths may be<unk> ed via either a pressure-triggered or a flow-triggered mechanism. Pressure triggered breaths are<unk> ed when the ventilator senses a negative pressure (indicating that the patient is trying to<unk> e a breath). During the flow-triggered mechanism, a continuous flow is delivered and a ventilator-delivered breath is<unk> ed when the return flow is less than the delivered flow.
