Oxygen Conservation Devices: Key Technologies for Reducing Oxygen Usage
Oxygen conservation aims to reduce the amount of supplemental oxygen required by patients who need it for medical reasons. Conserving oxygen can help patients remain more independent and active while still receiving the oxygen therapy they require. It also reduces healthcare costs by decreasing the quantity of expensive medical-grade oxygen that must be delivered and refilled. Several key technologies have been developed to allow for more efficient oxygen delivery and conservation.
Pulse Dose Oxygen Delivery
One method for optimizing oxygen use is pulse dose or pulse flow delivery. This involves delivering oxygen in periodic pulses or bursts rather than continuously. The bursts are timed to coincide with the patient's breathing cycle so Oxygen Conserving Devices is delivered only during inhalation. This mode of delivery reduces the amount of oxygen wasted during exhalation phases when no oxygen is absorbed by the lungs. Pulse flow devices sense the patient's breathing pattern and control solenoid valves to release oxygen only for the duration of inhalation. They have been shown to reduce oxygen consumption by up to 50% compared to continuous flow.
