Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

After informed consent, each volunteer will undergo the following techniques:

Simple mask at "flush" flow (40-60 L/min) Non-rebreather mask at 15 L/min Non-rebreather mask at 60 L/min Bag valve mask with one way exhalation valve at 15 L/min

After 3 minutes, the exhaled oxygen will be measured with an oxygen sensor

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Preoxygenation

All participants were enrolled in a single arm in which they underwent 4 interventions in series: 1) Simple mask at 60 L/min for 3 minutes 2) Non-rebreather at 15 L/min for 3 min 3) Non-rebreather at 60 L/min for 3 minutes 4) Bag valve mask at 15 L/min for 3 minutes

Group Type EXPERIMENTAL

Preoxygenation

Intervention Type DEVICE

After 3 minutes of oxygen supplementation (preoxygenation), with each of the devices listed below, the exhaled oxygen content will be measured. All participants were enrolled in a single arm in which they underwent 4 interventions in series: 1) Simple mask at 60 L/min for 3 minutes 2) Non-rebreather at 60 L/min for 3 min 3) Non-rebreather at 15 L/min for 3 minutes 4) Bag valve mask at 15 L/min for 3 minutes
