Document Summary
Lecture: respiratory disorders: structures of the airways, conducting - upper resp. Problems - you likely shouldn"t feed the patient and will likely have cardiac problems too. Abnormal collection of fluid in the pleural cavity. Normal - fluid enters pleural space via capillaries. Fluid can enter from the interstitial spaces in the lungs through the visceral pleura or from small holes in the diaphragm. Regulates how much fluid goes back and forth - keeping it from going to the alveoli and blocking gas exchange. Show up with fever (even if not infective), wbc rise, inflammation signs, dyspnea, dull breath sounds, decreased breath sounds. Complain of pleuritic pain - have to treat the pain. Blunt trauma - non-penetrating the pleural space that presses on the lung and causes lobe to collapse; air-filled bleb/blister) Hyper-inflated alveoli but no gas exchange bc of loss of capillary bed. Smoking increases number of neutrophils and elastase activation - increases damage of alveoli.
