YOUR DEVICE
2.1
Intended Use and Operation
The Mark 5 Nuvo Lite Family (Nuvo Lite and Nuvo Lite
3) Oxygen Concentrators are used as a means of
providing continuous oxygen enriched product gas for
patients, adolescent to geriatric, suffering from health
conditions that cause low levels of oxygen in the blood
(hypoxaemia).
To ensure your safety, use only after one or more
settings have been individually determined or prescribed
for you at your specific activity levels – AND – only use
the accessories that were used when your settings were
determined.
While undergoing oxygen therapy, if you feel discomfort
or experience a medical emergency, seek medical
assistance immediately.
The Mark 5 Nuvo Lite Family begins their operation
with air being pulled into the external air intake filter.
This filtered air enters the compressor via a suction
resonator and fine filter. Pressurized air then exits the
compressor and passes through a heat exchanger, which
reduces the temperature of the compressed air. Next, an
electronic valve system directs the air into one of two
tubes that contain molecular sieve (sieve beds). The
molecular sieve adsorbs (physically attracts) the nitrogen
from the air as it is pushed through the sieve beds. This
allows the oxygen enriched product gas to pass through
before being delivered to the pressure regulator. As one
tube is generating the product gas, the other is being
purged of the adsorbed nitrogen, this process is called
pressure swing adsorption (PSA). After passing through
the regulator, the rate of product gas being delivered to
the patient is set by the flow meter adjusting valve.
Finally, it passes through a fine particle filter and then
over a sensor that detects the oxygen concentration of the
product gas before it exits the device through a fire
resistant outlet.
