. STARTING UP / INSTALLATION
II.1. Use in direct oxygen therapy
a. Ensure that the switch (1) is in the
0
(OFF) position.
b. If used with a humidifier:
Unscrew the flask and fill it with water up
to the line (see humidifier instructions). Then
screw the lid on the humidifier flask until there
are no leaks.
c. Connect the oxygen tube to the humidifier outlet nozzle
or to the concentrator outlet if a humidifier has not been
prescribed. The tube between the cannula and the
Mark 5
Nuvo MB
should be limited to 20 meters (60 feet) long
,
in order to ensure that the oxygen flow rate remains within
specification values.
d. Ensure that all of the parts are connected correctly so as
to avoid leaks.
e. Plug the power cable into a power outlet
of the correct voltage and frequency as
defined on the manufacturer's technical
label (8).
f. Press the power switch
( I / 0 )
to the ON position
( I )
.
The green indicator will light when the oxygen concentration
exceeds the set point (OCSI) or normal operating pressures.
Note:
After turning the unit off, the user must wait 3-5
minutes before turning it back on. System pressure must
dissipate before the unit will properly restart.
g. Turn the flow adjustment knob (4) to the prescribed value.
This knob may have already been locked in the medically
prescribed position. In this case, do not force it. Only the
technician or medical personnel are authorized to release
it.
Note
: View the flowmeter in the horizontal plane for
accurate settings.
h. Check that the oxygen flows out of the administration
device (nasal cannulas or other) by placing the orifice(s) on
the surface of a glass of water. The flow should disturb the
surface of the water.
i. Adjust the nasal cannula to suit your face.
Note
: the required oxygen concentration is normally obtained
within five minutes after the unit is started.
At the end of the treatment, press the
I/0
Switch to place it
in the
0
(OFF) position to stop the device. The oxygen enri
-
ched air flow continues for approximately one minute after
the device is stopped.
