Overview

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.
