3.4.4 Output data (live and trend data)
3.4.4.1 Live data
The live data of the medinCNO ® contain the patient pressure, the set flow, the measured oxygen concentration,
whether a push is currently being emitted, all alarms, the set additional push flow and the current mode. In
addition, date, time, device name and software version are regularly indicated. The live data are automatically
and constantly indicated in normal operation. However, they are not saved in the medinCNO
®
. If the live data
are of interest, they must be recorded and saved by a computer or data system or the data will be lost. The
exact structure of the live data is described below:
Every 10 min., a line with these data is indicated:
- ***;
- Date;
- Time;
- Device name (can be set in the service menu);
- VXXX (CPU software version);
In the interim, the following data are provided every 0.1 sec (separated by ; ) via the USB interface:
- The currently measured CPAP pressure (in the CPAP, Apnoea CPAP and SNIPPV mode) or the CPAP
average value (in oscillation mode) in XX.X mbar
- Set target flow in XX.X L/min for the basic CPAP level; in the case of additional activation of the leak
assist, the target flow + correction flow is emitted.
-
Measured oxygen concentration FiO
2
XXX%;
- Current push activity X: 2 = Backup actively running (independent of whether there is currently a
push or not), 1 = push active (without backup), 0 = no push active;
- High-priority alarms (active alarms are indicated by a bit set at the corresponding site). The sum of
all active alarms XXXX is given (calculation in hexadecimal):

0x0001: Disconnection

0x0002: CPAP pressure high (fixed)

0x0004: Feed pressure high

0x0008: Gas feed oxygen

0x0010: Gas feed air

0x0020: Device error patient pressure measurement

0x0040: Flow stopped, reactivation via alarm reset

0x0100: Device error restart necessary
- Medium-priority alarms XXXX:

0x0001: Battery almost empty – Connect power supply unit

0x0002: CPAP pressure high (adjustable)

0x0004: CPAP pressure low (adjustable)

0x0008: Oxygen concentration high

0x0010: Oxygen concentration low

0x0020: Internal temperature too high
- Low-priority alarms XXXX:
