The TheraPEP features a built-in durable pressure indicator, 22mm OD patient end, inspiratory valve, and six fixed orifice options. The TheraPEP can accommodate the lung capacity of virtually every patient and provides immediate feedback of the prescribed pressure. It's strong design is resistant to breakage and the device can be used with a mask, mouthpiece, or a Nebulizer, and allows inhalation and exhalation without requiring removal from the mouth.
