FDA Product Code BZD: Ventilator, Non-continuous (respirator)

FDA product code BZD covers non-continuous ventilators, also known as intermittent positive pressure breathing (IPPB) devices and home respiratory support equipment.

Unlike continuous ventilators, these devices deliver assisted breaths only when triggered by the patient or on an intermittent schedule. They are used for the treatment of chronic respiratory conditions, post-operative respiratory therapy, and as backup support for patients with mild ventilatory insufficiency.

BZD devices are Class II medical devices, regulated under 21 CFR 868.5905 and reviewed by the FDA Anesthesiology panel.

Leading manufacturers include Respironics, Inc., Sleepnet Corporation and ResMed Corp.
