pNeuton (pronounced "new-ton"): 

a small, lightweight transport ventilator designed for use on patients from pediatric to adult in size.  Operating without the need of electrical power, the ventilator can care for the most difficult patients wherever they may be located.  pNeuton has simple to use controls with a built-in high output demand flow CPAP system.  The oxygen control system allows the operator to choose between 100% and 65% oxygen for spontaneous and mandatory breaths without the need for an oxygen mixer and air tank.  Use pNeuton in your ambulance, on your aircraft, within MRI or wherever you need mechanical ventilation.
