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.
Yes. It is good for people of any age to get that much exercise in per day.

An advantage of the syringe method is that blood appears in the hub when the vein has been entered.
It is the aorta. It is the biggest and the main artery
I’m pretty sure they included more than one independent variable.
