Answer: Some reasons for why we should being wearing masks is that it protects us from diseases. It doesn’t completely help us, but it does lower the chance by a lot of getting sick. It protects us from sicknesses from other people as well. When you cough, sneeze, or talk sometimes you can get some of you’re spit or mucus from the nose into the mouth of a person near you. Even if you do not have any sicknesses it is helpful to wear a mask so you do not. The type of material in a mask is important as well. If it may have a vent or something of the sort of in it, air and mucus can still get into the mask. One more reason you should wear a mask is that it could save you’re life.
Biotechnology researchers perform test and collect data and biotechnology technicians help operate the equipment.
I hope you figured it out
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.
