NSG 3315 Lecture Notes - Lecture 21: Hydrothorax, Atelectasis, Pleurisy
Document Summary
Hypoventilation > hypercapnia, hypoxia depression of respiratory center diseases of respiratory nerves or muscles thoracic cafe disorders. Po2 < 60 mm hg - aerobic metabolism stops and anaerobic metabolism takes over producing lactic acid. Impaired function of vital centers agitated or combative behavior, impaired judgement, convulsions, delirium, stupor, coma. Increased drowsiness, headache, intellectual impairment and disorientation > may lead to coma decreased muscle contraction vasodilation - headache, warm ushed skin. Pain is sudden and sharp localized to a particular area. Pleural effusions: collection of uid in the pleural space. Occurs when the rate of uid accumulation overcomes the rate of uid removal increased capillary pressure (chf) increased capillary permeability (in ammation) decreased colloidal pressure. Hydrothorax - accumulation of serous uid most common cause of chf. Chlyothorax - accumulation of lymph from the gi tract n the pleural spaces most common in cancer patients. Occurs from injury, malignancies, aortic aneurysm, or chest surgery.
