pNeuton model S ventilator with built-in CPAP for pre-hospital and hospital environments The pNeuton model S ventilator provides mask CPAP plus volume or pressure ventilation for use in the pre-hospital and hospital environments. The built-in CPAP (Continuous Positive Airway Pressure) system allows you to start with mask CPAP and if the patient needs it, provide ventilation as well. With simple-to-use controls – Tidal Volume, Respiratory Rate and Pressure Limit – pNeuton S can provide volume-targeted or pressure-limited ventilation. The built-in high output demand flow CPAP system insures critical care ventilation needs are optimized for spontaneous and mandatory breaths. Operates with no batteries, no electrical power Fully pneumatic and MRI compatible, the pNeuton S does not use batteries or electrical power. And it can help you care for the most difficult patients, from trauma site to the emergency room, for inter-facility transport, wherever the patient may be located; including the MRI.
