Stationary electric high-frequency ventilator

Stationary electric high-frequency ventilators are AC-powered machines designed to assist or control alveolar ventilation by delivering breaths at a frequency much higher than normal breathing rates and with tidal volumes equal to or less than anatomic dead space. They are commonly used in critical care settings to support patients with respiratory failure, often through an artificial airway like an endotracheal tube or tracheostomy.

These devices are typically supplied as part of a critical care system and may operate independently or in conjunction with standard ventilators to provide high-frequency percussive ventilation. Their use is specialized and intended for patients with severe respiratory conditions requiring advanced ventilatory support.
