B Respiratory System

(1) Hypostatic pneumonia. The depth and rate of respirations and the movement of secretions in the respiratory tract is decreased when a person is immobile. The pooling secretions and congestion predispose to respiratory tract infections. Signs and symptoms include:


Increased temperature.


Thick copious secretions.




Increased pulse.


Confusion, irritability, or disorientation


Sharp chest pain.



(2) Atelectasis. When areas of lung tissue are not used over a period of time, incomplete expansion or collapse of lung tissue may occur.

(3) Impaired coughing. Impairment of coughing mechanism may be due to the patient's position in bed decreasing chest cage expansion.
