Question

intensive care unit patients who are on respirators are usually lying on their back. In this position, sometimes high air pressures are required to inflate the lungs adequately for gas exchange. This high inflation pressure poses the danger of rupturing the lung. If the patient is turned on their side, however, ventilating the lungs becomes easier, and the higher pressures are not necessary. This is becauses when a person on their:

a. side, the phrenic nerves are less compressed by thoracic and abdominal contents.  

b. side, their rib cages have a higher elasticity, allowing for better expiration.

c. back, abdominal contents put pressure on the diaphragm.

d. back, the phrenic nerves are more stretched by the artifically expanded diaphragm.  

Explanation / Answer

Answer

Phrenic nerve: It is bilateral nerves which passed information from brain to thoracic cavity .It is positioned towards neck and pass to the thoracic cavity from both side.

When a person in lay down position the sectreat from the lung is accumulated in the alveolar tissue and prevent the person in breathing or difficulty in breathing but when the person lay down in side position then the secret is passed to the deep tissue and there is no clouging in the lung and helps in normal breathing.

So

b) side,their rib cage have a higher elasticity,allowing for better expiration.
