What type of power source do most noninvasive ventilation (NIV) ventilators utilize?

Most noninvasive ventilation (NIV) ventilators utilize an electrically powered source. This is primarily due to the need for precision and control in delivering positive airway pressure to the patient, which electrically powered units can provide effectively. These ventilators require a stable and consistent power supply to operate complex functions such as adjusting pressure levels, monitoring patient responses, and managing alarms.

Electric power enables the ventilators to integrate with other hospital equipment, ensuring seamless operation in clinical environments. It also allows for features like humidification and heating of inspired gases, which are crucial for patient comfort and airway protection during ventilation.

Choosing an electrically powered option ensures that the device can quickly respond to patients' needs and provide the necessary ventilation support without relying on other less reliable power sources.
