June 18, 2007 — Newport Medical Instruments, Inc. recently announced that its newest generation of ventilator, the Newport e360, has added a new Biphasic breath type in its latest software version.
Biphasic Pressure Release Ventilation (BPRV) allows free inhalation and exhalation during a pressure-controlled breath by means of a partially open, actively controlled exhalation valve. The goal of BPRV is to improve patient comfort, reduce the expiratory work of breathing and possibly improve oxygenation when the patient has an intact respiratory drive.
