What is the main function of a ventilator?

The main function of a ventilator is to assist or control the breathing of a patient. Ventilators are essential medical devices used in various clinical settings to support individuals who are unable to breathe adequately on their own due to illness, injury, or sedation. They deliver a controlled flow of oxygen and can be set to provide the necessary pressure and volume to ensure that the patient receives an appropriate level of ventilation. This function is critical in emergency situations, surgeries, or for patients with chronic respiratory conditions.

The design of a ventilator allows it to tailor the breathing support according to the patient's specific needs, which can include continuous positive airway pressure (CPAP), pressure support, or mechanical ventilation. By doing so, ventilators help maintain adequate oxygenation and carbon dioxide removal, thereby stabilizing the patient's respiratory status.
