Module 6: Respiratory Disorders Flashcards
Dyspnea
Discomfort in breathing (shortness of breath)
Orthopnea
Discomfort in breathing while lying down
PND
Paroxysmal nocturnal dyspnea - waking up at night unable to breathe normally
Hemoptysis
Coughing up blood
Cyanosis
Bluish pigment of skin and mucous membranes due to increased amount of deoxygenated hemoglobin in the blood
Clubbing
Selective bulbous enlargement at the end of a finger
Hypercapnia/hypercarbnia
Increased amount of arterial carbon dioxide
Hypoxemia
Reduced oxygenation of arterial blood
Hypoxia
Reduced oxygen supply to tissues
V/Q ratio
Refers to the ratio of air reaching the alveoli (ventilation) and the blood that the alveoli receives via capillaries (perfusion)
Physiological right to left shunt
Blood moving through unventilated parts of the lungs so no GAS EXCHANGE occurs between alveoli and the blood. Basically, blood moves from the right ventricle, to the lungs, then to left ventricle without being oxygenated
Flail chest
Chest moves in with inspiration and out with expiration (paradoxical movement) caused by trauma to chest that fractures consecutive ribs
Pneumothorax
Presence of air in the pleural cavity caused by a rupture in visceral or parietal pleura
Pleural effusion
Excess fluid in the pleural space
Empyema
Infected pleural effusion
