Respiratory review

A reduced number of red blood cells (RBCs) in the blood results in the following change in the oxygen saturation (SaO2) of the blood:

• The SaO2 would increase.

• The SaO2 would decrease.

• The number of RBCs will not affect SaO2.

• There will be a decrease only if the osmotic is also decreased.

Emphysema differs from chronic bronchitis in that emphysema:

• Is characterized by mucus production and inflammation.

• Obstructs the large airways.

• causes enlargement of the alveoli

• is virtually the same condition as chronic bronchitis
