Oxygen is a basic human need. We would not survive without it. The
air that we breathe accounts for around 21% oxygen. It can be
sufficient for most people with healthy lungs, but for some people
with certain health conditions whose lung function is impaired, the
amount of oxygen that is obtained through normal breathing is not
enough. Oxygen concentrator can separate oxygen and nitrogen
molecules from each other for generation of high concentration
oxygen. Trapping the nitrogen out of the compressed air and
provides supplemental oxygen by compressing room air to 4
atmospheres of pressure. This concentrates the oxygen in the
compressed air without the need of adding chemicals.
When deciding what kind of oxygen concentrator is best for you, it
is important to determine what kind of oxygen delivery you would
prefer: Pulse Dose or Continuous Flow.Pulse Dose vs. Continuous
Flow: The DifferencePulse Dose (PD) is based on breathing and
inhaling, whereas Continuous Flow (CF), as its name implies, is
delivered at a constant rate indiscriminate of the user's
breathing.For continuous flow, think of it like a water fountain:
If an individual stands in front of a water fountain flowing at 1
liter per minute, they don't actually drink one full liter of
water. The amount of water a person drinks is a product of the
number of sips and the size of the sip. The rest of the water is
wasted.he amount of water a person drinks is a product of the
number of sips and the size of the sip. The rest of the water is
wasted. The same applies to continuous flow oxygen; the net amount
inspired is a combination of the flowrate, the number of breaths
and the size of the breaths.Pulse Dose is more sophisticated. Pulse
Dose mechanisms are more sensitive, utilizing an oxygen conserver
and other technology to deliver oxygen based on breathing rates and
other factors. PD is more akin to a glass of water with a straw
than a fountain; the intake will be based purely on the amount and
intensity of sips. When an oxygen concentrator is said to be a
"single-solution" for on-the-go, at home, and sleep, it usually
employs this type of technology so that it can deliver the proper
amount of oxygen during all phases of daily activity and during
rest.
