What is Pulse Dose?

Pulse flow or pulse dose is the delivery of a “bolus,” or a puff of oxygen every time you breathe, or more specifically, when you inhale. A sensor in the Airsep Focus, detects the force or pressure of your breath and triggers the concentrator to deliver your dose of oxygen prescribed by your doctor.

Pulse flow delivery on a Airsep Focus can help maximize your unit’s battery life by giving you the oxygen when you inhale and not wasting precious battery power by constantly delivering oxygen. On an oxygen portable unit pulse dose delivery helps maximize your portable duration by giving you oxygen when you inhale and not wasting any oxygen. This allows the oxygen portables to last for many hours and allows you to stay most active without worrying about having to refill or run out of oxygen. Pulse flow is typically used for portability and when a patient is active.

How Does an Oxygen Concentrator Work?

The ambient air we breathe contains approximately 21% oxygen, 78% nitrogen, and 1% other gasses. The Airsep Focus does not “create” its own oxygen. It draws in room air into the machine using an air compressor. This air usually passes through some type of filtration as it enters the concentrator to remove dust and other small particulates. Once inside of the concentrator, the room air passes through an adsorbent material called molecular sieve. The molecular sieve adsorbs the nitrogen in the room air, separating the oxygen from it and allowing the oxygen to pass through. Oxygen exits the concentrator and is delivered to the patient in high concentrations of > 90% purity.
