How long will the oxygen in a SmartDose unit last on a patient?
Because the SmartDose units deliver a prescribed dose per breath, then adjust when the wearer exerts, this will vary from patient to patient. A patient on a “2” setting breathing at 20 breaths per minute will have more ambulatory time than someone on a “3” setting who is breathing at 35 breaths per minute. This is not specific to SmartDose, however, as duration of all oxygen portables is subject to how the patient uses the unit. Frequently users of other units turn the setting up and sometimes forget to turn it down again, limiting the duration of the unit. With its automatic adjustment technology, SmartDose minimizes the need to “self-titrate” and increases the amount of time the oxygen in the unit will last.
