Hayat will request for ordering physician to qualify a patient for a portable concentrator in order to create a continued active life for oxygen patients.  The traditional tank system creates a challenge for patients to ensure an active life due to their dependency on having enough tanks in order to be mobile.  Hayat will reach out to the physician for an order so that Hayat can test the patient on pulse mode oxygen concentrator in order to provide the patient with the lightest and most effective system within 7 – 10 days of being discharged.  Finally, Hayat will provide all oxygen patients on the portable concentrator model in order to promote a more active lifestyle and less dependency on tanks.
