What is the recommended initial setting for ventilating pressure when delivering NIV in a pressure-triggered mode?

When delivering noninvasive ventilation (NIV) in a pressure-triggered mode, the recommended initial setting for ventilating pressure is 8 - 12 cm H2O. This range is ideal because it provides adequate support to initiate ventilation without excessively increasing the work of breathing for the patient.

Setting the pressure within this range helps to ensure that the patient receives sufficient tidal volume while remaining comfortable. It also minimizes the risk of complications associated with higher pressures, such as increased airway resistance or potential barotrauma.

In practice, clinicians may adjust the pressure based on the patient’s clinical response, oxygenation and ventilation needs, as well as comfort, after starting within this recommended range. This initial setting balances effective ventilation support and patient tolerance, making it a crucial starting point in the management of respiratory failure with NIV.
