ClinConnect Summary

This clinical trial is investigating the best way to prepare patients for anesthesia by comparing three different methods of increasing oxygen levels in the body. The methods being tested include a non-rebreather face mask, a bag-valve-mask with extra pressure support, and a bag-valve-mask without that extra support. The study aims to find out which method is most effective in raising oxygen levels during emergencies.

To join the study, participants should be healthy adults or children aged 6 to 12. Eligible adults should have a normal weight or be slightly overweight but in good health. People with certain health conditions, those under 6 or over 18, pregnant women, and anyone showing signs of respiratory illness on the study day cannot participate. Participants will undergo a series of oxygen tests while lying down, using each of the three methods in a random order. The study will measure how well each method works in increasing oxygen levels over a short period. This research could help improve safety for patients undergoing anesthesia in emergency situations.
