Larson, Project ManagerDate: 11/14/2011Re: Motor Sizing for Oxygen Pressure ControlDist: H.L. Smith, M.D., Director of Research, Respiration DivisionOur company is currently developing a new type of oxygen delivery system for emergency response personnel, and we require an expert opinion on how to size our pumping components. Existing protocols for oxygen delivery typically call for a fixed flow rate of oxygen to the patient, with manual pressure on a breathing mask or oxygen bag used to adjust pressure. We believe that for certain medical conditions where the patient is clearly conscious and responsive, more benefit may be obtained if an oxygen supply is maintained at slightly elevated pressures, but with flow rate variable according to the patient’s own activity.
