During bag-mask ventilation, giving a breath just until you see the chest rise is recommended to minimize the risk of gastric inflation. The compression-to-ventilation ratio for 1-rescuer adult CPR is 30:2<span>. The compression-to-ventilation (or breaths) ratio for 2-rescuer child/infant CPR is </span>15:2<span>.</span>
Can you provide more of the question so I can answer it?
I believe 6CO2 is the answer
Answer:
The answer is the accessory nerve.
Explanation:
We have 12 pairs of cranial nerves, the accessory nerve is the XI pair. This is responsible for the innervation of the sternocleidomastoid and trapezius muscles.
The fibers of the accessory nerve originate from neurons that are located in the upper spinal cord. These fibers join together forming roots and once the nerve is constituted, it enters the skull through the great hole that is located at the base of the skull.
Then, the nerve continues its path along the inside of the skull in the direction of the jugular hole and then leaves the skull next to the glossopharyngeal nerve (IX) and the vagus (X).
Thus, the accessory nerve enters and leaves the skull again, characterized by being the only cranial nerve which has this behavior.
