Medical Ventilator System and Method Using Oxygen Concentrators
First Claim
1. A method of using a medical ventilator system for at least one of increasing fraction of inspired oxygen delivered to a patient and conserving oxygen, the medical ventilator system including an oxygen source for pulsed delivery of a bolus of oxygen;
- a medical ventilator;
a ventilator circuit for connecting the ventilator to the patient, the ventilator circuit including a location proximal to the patient, comprising;
delivering with the ventilator a breath to the patient during an inspiration cycle;
adding a pulsed delivery of a bolus of oxygen from the oxygen source to the breath from the ventilator during the inspiration cycle to the location proximal to the patient of the ventilator circuit for at least one of increasing fraction of inspired oxygen delivered to a patient and conserving oxygen.

Abstract
A medical ventilator system that allows the use of pulse flow of oxygen to gain higher FIO2 values and/or conserve oxygen is described. In one embodiment, the ventilator system includes an oxygen concentrator, a medical ventilator and a breathing circuit between the ventilator and a patient. In one embodiment, the oxygen concentrator includes a controller module that is configured to generate a trigger signal to initiate the distribution of one or more pulses of oxygen from the oxygen concentrator to the patient circuit at the onset of a ventilator supplied breath. A small flow of oxygen can be added in between pulses to aid in gaining higher FIO2.
