hyperventilation

depression of respiratory center

impaired diffusion of gases is…

hypoxemia but not hypercapnia

impaired diffusion

interstitial lung disease, ARDS, pulmonary edema, and pneumonia

mild hypoxemia

increase heart rate peripheral vasoconstriction diaphoresis

chronic hypoxemia

pulmonary vasoconstriction cyanosis clubbing

hypercapnia

High CO2

effects of hypercapnia

increase respiratory

Pleuritis inflammation symptom

Pain

Pleural effusion

Accumulation of fluid in the pleural cavity

Hemothorax

Blood in the pleural cavity

Pneumothorax
