Smart Dose – The SmartDose Oxygen Conserver by Drive Medical will sense patient breath rate and turn oxygen flow up and down as needed, within seconds. As you perform strenuous activities you will receive an appropriate amount of oxygen to keep you going, while at low breathing rates this conserver excels at saving money by lowering the dosage. This technology maximizes conservation so that each tank will last longer, saving money and time spent replacing them. Electronic conservers are necessary if you are looking for a conserver, but your respiration is too weak to power a pneumatic conserver. The easy to read panel makes using the SmartDose simple and aggravation-free.
