Unit 2: Chapter 41 Flashcards
Acute Coronary Syndrome
AKA Myocardial Infarction; sudden decrease in coronary blood flow
Afterload
resistance to the ejection of blood from the left ventricle
Angina Pectoris
transient imbalance between myocardial oxygen supply and demand
Bilevel positive airway pressure (BiPaP)
works by providing assistance during inspiration and preventing alveolar closure during expiration
Capnography
AKA end-tidal CO2 monitoring; provieds instant info about patients ventilation, perfusion, and how effective CO2 is produced
Cardiac Output
Blood ejected from the left ventricle
Cardiopulmonary rehabilitation
Patients achieve and maintain an optimal level of health through controlled physical exercise, nutritional counseling, relaxation and stress management techniques
Chest tube
catheter inserted through the rib cage into the pleural space to remove air, fluids, or blood
Cheyne-Stokes respiration
dec. blood flow or injure to the brainstem; breathing appears with patterns of apnea followed by deep breathing and then shallowing breathing
Continuous positive airway pressure (CPAP)
maintains a stream of pressure throughout a patients breathing cycle
Diffusion
responsible for moving the respiratory gases from one area of concentration to another
Ventilation
process of moving gas in and out of lungs
Perfusion
body’s ability to pump oxygenated blood through body and return deoxygenated blood to the lungs
Hematemesis
vomiting of blood
Hemoptysis
coughing up blood
hemothorax
Accumulation of blood and fluid in the pleural space
hypovolemia
reduced circulating blood volume
Hypoxia
inadequate tissue oxygenation
Kussmaul Respiration
fast, deep breaths as a response to metabolic acidosis
Pneumothorax
Air in the pleural space
Preload
amount of blood in left ventricle before next contraction
Stroke Volume
volume of blood ejected from ventricles during systole
