When mechanical ventilation is initiated, a humidification method should be chosen. There is two methods: heat and humidity exchanger filters or heated humidity. The second method is recognized to be more efficient, but many external factors can influence its performance. Insufficient humidity results in observable problems, such as difficult management of respiratory secretions. The study compare two heated humidifiers already used in ICU. Data will be collected retrospectively from June 1, 2021.

RECRUITINGEndotracheal tube occlusion requiring emergency tube change
Under-humidification episodes are defined as follows: \- Occurence of endotracheal tube occlusion requiring emergency tube change
Time frame: At the end of the mechanical ventilation period or at 21 days ( the first of the 2 occurred)
Bronchoscopy
Under-humidification episodes are defined as follows: \- Occurence of performing a bronchoscopy for a suspected sub-occlusion (thick or sticky secretions), and the total number of bronchoscopies performed per patient
Time frame: At the end of the mechanical ventilation period or at 21 days ( the first of the 2 occurred)
Tracheal saline instillations
Under-humidification episodes are defined as follows: \- Occurence of tracheal saline instillations due to sticky secretions or suspected endotracheal tube sub-occlusion
Time frame: At the end of the mechanical ventilation period or at 21 days ( the first of the 2 occurred)
Thick secretions
Under-humidification episodes are defined as follows: \- Occurence of tracheal secretions describe at thick secretions (rated at 5 on the secretions scale used at the hospital) or "sticky secretions" if specified
Time frame: At the end of the mechanical ventilation period or at 21 days ( the first of the 2 occurred)
Change humidifier settings
Under-humidification episodes are defined as follows: \- The number of operations required to change humidifier settings if the plate temperature is below 62 degrees Celcius (with the MR850).
Time frame: At the end of the mechanical ventilation period or at 21 days ( the first of the 2 occurred)
Other elements that may be influenced by the quality of the humidification used during mechanical ventilation
These data will be collected: * mechanical ventilation time * length of stay in intensive care * ventilation pressures * use of bronchodilator aerosols. * Ambien room air temperature
Time frame: At the end of the mechanical ventilation period or at 21 days ( the first of the 2 occurred)
