A client abruptly sits up in bed, reports having difficulty breathing and have an arterial oxygen saturation of 88%. Which oxygen delivery method would give the greatest level of inspired oxygen?

a. Non-rebreather mask

Explanation:

The Non-rebreather mask is a mask that has a reservoir-like bag attached to it. It enables for the free delivery of high concentration of oxygen. It also have a reservoir where the patient can exhale carbon dioxide.

It delivers oxygen concentration between 60% to 80%.

Non-breather masks.

Explanation:

If the client could have percentage saturation of oxygen at 88%, it indicate active breathing by the client, and he/she did not need to be assisted with breathing. Therefore to sustain her oxygen saturation pressure high percentage of oxygen must be given to the client. This is the uses of Non-breather mask to deliver oxygen at high concentration to patients in chronic conditions but  still capable of self breathing.

The mask  is worn around the nose and mouth,  and held by plastic cord around the head. It is directly connected to a 1 liter reservoir  of oxygen for continuous supply. .And exhaled air is empty through a  valve  with one opening to the surrounding environment with no infiltration from surrounding oxygen.

it is applicable to patients with CO gas poisoning, smoke inhalation, and physical trauma.

the more fit you are, the faster the recovery. your heart rate drops most sharply in the first minute after you stop exercising; it should then fall about 20 beats a minute—a drop of less than 12 beats a minute is considered abnormal. this “recovery heart rate” is measured as part of an exercise stress test.
