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.
Genetics or lifestyle. Meaning tobacco use, etc.

<span>Congestive
heart disease and asthma are examples of chronic conditions. Chronic diseases
refer to diseases that have lasted for three months or more. It cannot be
prevented by vaccines, cured by medications, and they do not just disappear. It
requires medical attention and proper care. Congestive heart diseases (CADs)
usually appear in many forms, the common ones are arteriosclerosis (hardening
of the arteries) and atherosclerosis (blockages in the blood vessels). While
asthma is a disease that is hereditary and can worsen when exposed to different
environmental pollutants (e.g. smoke, extreme cold).</span></span></span>
