Portable medical ventilator system using portable oxygen concentrators

A method of delivering inhalation gas and supplemental oxygen to a patient using a ventilator and a supplemental oxygen source, the method comprising:

• directing, using a positive pressure source positioned within the ventilator, the inhalation gas to a patient circuit for delivery to the patient;
• generating, using a negative pressure source positioned within the ventilator, a negative pressure;
• applying the negative pressure against the supplemental oxygen source, wherein applying the negative pressure against the supplemental oxygen source triggers the supplemental oxygen source to release the supplemental oxygen;
• and
• routing the supplemental oxygen to the patient circuit for delivery to the patient.

A method of delivering a first gas and a second gas to a patient using a ventilator and a supplemental gas source, the method comprising:

• directing, using a positive pressure source positioned within the ventilator, the first gas to a patient circuit for delivery to the patient;
• generating, using a negative pressure source positioned within the ventilator, a negative pressure;
• applying the negative pressure against the supplemental gas source, wherein applying the negative pressure against the supplemental gas source triggers the supplemental gas source to release the second gas;
• and
• routing the second gas to the patient circuit for delivery to the patient.

A method of delivering supplemental oxygen to a patient using a ventilator and a supplemental oxygen source, the method comprising:

• generating, using a negative pressure source positioned within the ventilator, a negative pressure;
• applying the negative pressure against the supplemental oxygen source, wherein applying the negative pressure against the supplemental oxygen source triggers the supplemental oxygen source to release the supplemental oxygen;
• and
• routing the supplemental oxygen to a patient circuit for delivery to the patient.
