Question

1-How would you know that the airway is obstructed in an unconscious patient?

2-How would you keep air in the cuff of an airway which does not have a one-way valve at the pilot balloon?

3-What are some reasons why the cuff may not hold a given volume of air?

4-Why might it be a good idea to use a three-way stopcock arrangement needed to measure cuff pressure?

Answer 1

answer is given below

1.place the ear close to the patients mouth and watch for chest movement.look,listen ,you feel for breathing for 5 seconds.if the chest still does not rise,the air way is likely blocked

2 A cuff is a balloon attached around the outside of the tube .the cuff is inflated by filling the pilot balloon with air,which fill the cuff

3 usually inject 0.5cc of air at a time until air cannot be felt or heard escaping from the nose or mouth(usually 5 to 8 cc )

4. the cuff pressure was measured with a commercial manometer extension to the tracheal tube pilot ballon via a three way stopcock
