What are the three common modes seen on NIV ventilators?

The selection of CPAP, spontaneous, and timed as the three common modes seen on noninvasive ventilation (NIV) ventilators is particularly accurate because these modes are widely used to manage patients with respiratory failure while ensuring patient comfort and adequate ventilation.

CPAP (Continuous Positive Airway Pressure) maintains a constant level of positive pressure in the airways throughout the breathing cycle, preventing airway collapse and improving oxygenation. This mode is often utilized in conditions such as obstructive sleep apnea and certain types of acute respiratory failure.

The spontaneous mode allows patients to initiate their breaths, with the ventilator providing support as needed. This is beneficial for patients who can breathe independently but still require some assistance to meet their ventilation needs.

Timed mode, also known as timed spontaneous ventilation, allows the ventilator to provide assistance based on a preset respiratory rate while still allowing spontaneous efforts by the patient. This gives flexibility in supporting patients who may have varying degrees of respiratory effort.

Together, these modes provide a balanced approach to noninvasive ventilation, catering to the needs of various patients while promoting comfort and participation in the breathing process.

Other choices do not represent standard modes for NIV. For instance, volume control and pressure control are more closely associated with invasive mechanical ventilation rather than non
