Family 1st Medical is pleased to feature a variety of portable systems. Conventional oxygen systems deliver a continuous flow of oxygen, wasting gas when the patient exhales. These units are also heavy and awkward to carry. The Oxygen Conservation Device (OCD) portable systems sense each breath and deliver oxygen only when the patient inhales. Oxygen is conserved making tanks last 3-5 times longer. These lightweight - easy to carry systems can be rented or purchased. Contact our Respiratory Staff for details. Once again lead an active fulfilling life thanks to portable systems. Contact us at: respiratory@family1stmedical.ns.ca
