(resusc./ventilator) PEEP VALVE 20, inlet conn.30mm,reusable
Valid Article
PEEP - Positive End Expiratory Pressure Valve
Definition
A non-sterile device used in a respiratory or anaesthesia breathing circuit or system to maintain a selected level of positive end expiratory pressure (PEEP) in a patient's airway during ventilation.
The device is typically constructed of plastic and metal materials, and has a valve(s) actuated with a spring(s) to provide the airway resistance, and an adjustable knob or dial (usually graduated) to adjust the resistance level typically between 5 to 20 cm H2O.
It is used with ventilators, stand-alone breathing systems for oxygen delivery, pulmonary resuscitators, or anaesthetic breathing systems often having an expiratory valve function. This is a reusable device.
