The “Manual Breath” can be activated during FOT, but this will deactivate FOT.
To re-enable FOT after a Manual Breath / Sustained Inflation, you must restart
FOT from the beginning.
The Start / Stop button can be used to interrupt mechanical ventilation for two
minutes, but this will deactivate FOT.
Any FOT measurements taken during Standby are NOT vaild.
Inaccurate measurements may be caused by:
• Flow sensor not calibrated or defective;
• Incorrect pressure measurement line application or use;
• Excessive patient spontaneous breathing (strong active respiratory
drive);
• Excessive leakage at the patient interface.
12.6.5 FOT procedure
Perform the following steps to complete an FOT procedure.
1. Terminate any ongoing EtCO
2
measurements during FOT procedure as it can affect the results.
2. Ventilate in one of the compatible ventilation modes with an active flow sensor.
2.1. Verify that the flow sensor in the selected mode is calibrated.
2.2. If Flow sensor is NOT calibrated, calibrate the Flow sensor and continue with the
procedure.
3. Go to the Curves / Loops menu by pressing the Graphics button on the front panel and select
FOT submenu.
4. Set the three adjustable parameters (FOTsteps, low and high-pressure settings) according to the
needs (FOT contains a recruitment and a derecruitment phase starting at the set low pressure
level and turning back at the high-pressure level).
4.1. Adjust the pressure related alarms to avoid unnecessary patient alarms during the
maneuver.
5. When all FOT parameters are set appropriately for the patient’s respiratory system, FOT is
ready to be initiated by pressing the ON / OFF button, which will turn Green and a confirmation
message will appear on the display.
