2.5 Technical description of function
2.5.1 Principles of function
The medinCNO
®
is a CPAP driver that can be used in combination with the Medijet
®
nCPAP generator to
administer CPAP therapy. The role of the medinCNO ® in this CPAP system is to provide the necessary, possibly
oxygen-enriched drive flow, which is fed to the nCPAP generator Medijet ® via the tubes connected to the
patient and is converted into CPAP pressure within the generator.
An internal electronic blender combines the air and oxygen coming from an external source and administers
the total volume so that the drive flow reaching the patient can be enriched with oxygen as necessary to any
oxygen level between 21% and 100%.
The flow volume of the gas mix within a range of 4 L/min to 15 L/min can be set depending on the mode
selected. According to the flow volume set, the medinCNO ® provides a constant drive flow. This generates a
constant CPAP pressure in the Medijet ® CPAP generator, or the medinCNO ® assesses the CPAP pressure signal
measured in the Medijet
®
in order to react to the patient's breathing and trigger a higher flow impulse in the
event of apnoea or synchronously with the patient's inhalation. This triggers a pressure impulse with elevated
CPAP pressure in the Medijet ® CPAP generator. The medinCNO ® can also trigger oscillation between 5 Hz and
20 Hz in the CPAP pressure applied by Medijet ® by means of an oscillating drive flow.
The monitor which is part of the medinCNO ® displays the parameters selected by the user, the sensors’
readings, the length of time that CPAP pressure has been applied by Medijet
®
in the form of a graph, and any
alarms.
The medinCNO
®
can operate for up to three hours without mains power thanks to its rechargeable battery.
Warning:
The medinCNO
®
may not be modified without permission from the manufacturer and subsequent appropriate
examinations and testing to ensure continued safe use.
