C) speaking in a moderate and assertive tone
A bag-mask is a medical device designed to ventilate a patient in respiratory arrest.
It must be on hand in an emergency department of the hospital or an ambulance.
It can be used before or after intubation while waiting for a mechanical respirator.
It can be used in CPR.
The bag-mask is preferably connected to a source of oxygen.
To use it requires 2 hands:
The right-hand holds the ball and exerts pressure with the 4 fingers to push the air (press with the thumb is an error).
The left hand applies the mask to the mouth and the nose, keeping a good seal, then putting the hand on the chest of the victim to check if there is an expansion/shrinkage of the rib cage due to the entry of the air.
Parasites I believe, but if this is multiple choice it would be helpful if you were to list the answers.∞
