Evaluation of Gas Humidification Practices in Patients Under Invasive Mechanical Ventilation: Benefit of the F & P950 Heated Humidifier Compared With the MR 850 on Clinical Events of Under-humidification

What this Trial Is About

Researchers are evaluating the use of two different heated humidifiers for patients who require invasive mechanical ventilation in intensive care. The study aims to compare the effectiveness and clinical outcomes of the Fisher & Paykel MR850 and FP950 humidifiers. Mechanical ventilation requires proper humidification to manage respiratory secretions and prevent complications, and this study focuses on assessing these humidification methods based on data collected retrospectively starting from June 2021. The study involves two groups of patients, each using one of the two heated humidifiers (MR850 or FP950) during their mechanical ventilation period, which is expected to last longer than 24 hours. Both humidifiers are already in use in ICU settings, and the study will observe their impact on clinical events related to insufficient humidification. The comparison focuses on practical application and performance in real clinical scenarios. Participants are monitored for events such as endotracheal tube occlusion requiring emergency tube change, bronchoscopy, tracheal saline instillations, presence of thick secretions, and changes in humidifier settings during the mechanical ventilation period or up to 21 days. Data collection is retrospective, and the study will also look at other factors potentially affected by humidification quality. This research is sponsored by Laval University and will continue until July 2026.
