During a ventilation sequence, the user started the "100% O2" function. This function lasts for two minutes but can be interrupted by pressing the 100% O2 key. Note: after the 100% O2 function has been used, the FiO2 setpoint originally entered is reapplied. The user wanted to change the FiO2 setpoint a few seconds before the end of the two-minute period of the 100% O2 function, and the confirmation of this setpoint took place just after the end of the 100% O2 function, which can cause a conflict between the setpoint applied and its display.
