Oxygenation, Circulation, Perfusion Flashcards
ventilation
process of moving gases in and out of the lungs
tidal volume
amount of air exhaled after normal inspiration
residual volume
amount of air left after a full exhalation
forced vital capacity
the max amount of air removed during a full exhalation
perfusion
ability of the cardiovascular system to pump oxygenated blood to the tissues and return deoxygenated blood to the lungs
dysrhythmia
disturbance in conduction; irregular heart rhythm
cardiac conduction pathway
stimulus starts from SA node –> travels through intermodal pathways to AV node –> bundle of His –> separates left and right –> ends at Purkinje fibers
stenosis
hardening of the valves; valves cannot fully open and close
angina pectoris
chest pain caused by imbalance between myocardial oxygen supply and demand
myocardial infarction
necrosis of heart muscle caused by total blockage of coronary artery
atelectasis
collapse of alveoli; a cause of hypoventilation
bronchoscopy
pass a flexible tube (bronchoscope) into the patient’s respiratory tract for visualization
thoracentesis
involves surgical perforation of chest wall with a needle, into pleural space, to aspirate fluid for diagnostic purposes or to remove effusion
hemogram
complete blood count
