Effectiveness of Two Different Body Positions During Facemask Ventilation in Obese Patients
Effectiveness of Two Different Body Positions During Facemask Ventilation in Class 3 Obesity Patients: a Randomized Crossover Trial
Source: ClinicalTrials.gov · Last updated 17 Jun 2026
Brief summary (registry, in English)
It is important to provide enough oxygen to the patients who are asleep during surgery. One way to do this is by using a mask placed over the face to help them breathe. When it becomes difficult getting enough oxygen into the patient's body using the mask, it's called difficult mask ventilation. There can be different reasons for this, and having a higher BMI is one of them. Body physique is assessed by Body Mass Index (BMI). This calculation gives an indication of a person's weight relative to their height. There is some evidence in the research literature to suggest that when the patient is positioned in a way that helps their airway, like using a device to lift their head and torso 25 degrees , it might help the process of getting enough oxygen work better. The study aims to determine if patients with high BMI can breathe better using a face mask while they are in a head elevated position compared to lying flat on their back.
