16. Operational considerations
16.1 General
16.1.1 Standby mode
The patient must not be connected to the unit in “Standby” mode. The unit
does not deliver any therapeutic flow in this modes. In “Standby” mode all
patient and gas alarms are disabled with the exception of the “Low battery”
alarm and all system failure alarms.
16.2 CPAP
16.2.1 CPAP setting of 2 to 4 mbar
If the user is using the SLE1000 with small or medium prongs and a CPAP
pressure of between 2 and 4 mbar, the unit may not detect the disconnection of
the patient from the circuit.
The SLE1000 must not be used as the sole form of patient monitoring.
Independent monitoring of blood gases must be used in conjunction with
the SLE1000. Breath detection technology used in the apnoea monitor
function is based on rate and magnitude of change in the pressure
measured in the patient interface (that is shown on the bar graph). The
sensitivity of the technology has limitations with the smallest patients
(<1000g) and if a leak exists or if the patient opens/breathes by the mouth.
The apnoea monitor may be disabled if breath non-detection results in
nuisance apnoea alarms.
16.2.2 Setting pressure trigger sensitivity
When delivering CPAP with Apnoea detection turned ON the user may have to
adjust the pressure trigger sensitivity. The method of setting the pressure trigger
sensitivity is described in’9.2.1 Pressure trigger sensitivity’ on page 37. If the user
deems that the BPM rate is high due to reasons other than patient effort then they
can decrease the sensitivity by reducing the value from the default of 3 down to 1.
The user can increase the sensitivity by increasing the value from 3 to 6. Patient
trigger detection determines the delivery of backup breaths in an apnoeaic
episode.
