Humidifier Lung, Mechanical Fragility, Respiratory Complication
Conditions
Brief summary
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.
Interventions
This humidifier will be used straight away for patients whose intubation is expected to last longer than 24 hours.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Endotracheal tube occlusion requiring emergency tube change | At the end of the mechanical ventilation period or at 21 days ( the first of the 2 occurred) | Under-humidification episodes are defined as follows: \- Occurence of endotracheal tube occlusion requiring emergency tube change |
| Bronchoscopy | At the end of the mechanical ventilation period or at 21 days ( the first of the 2 occurred) | 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 |
| Tracheal saline instillations | At the end of the mechanical ventilation period or at 21 days ( the first of the 2 occurred) | Under-humidification episodes are defined as follows: \- Occurence of tracheal saline instillations due to sticky secretions or suspected endotracheal tube sub-occlusion |
| Thick secretions | At the end of the mechanical ventilation period or at 21 days ( the first of the 2 occurred) | 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 |
| Change humidifier settings | At the end of the mechanical ventilation period or at 21 days ( the first of the 2 occurred) | 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). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Other elements that may be influenced by the quality of the humidification used during mechanical ventilation | At the end of the mechanical ventilation period or at 21 days ( the first of the 2 occurred) | These data will be collected: * mechanical ventilation time * length of stay in intensive care * ventilation pressures * use of bronchodilator aerosols. * Ambien room air temperature |
