Oxygenation (test 3) Flashcards
Cardiac Output
Amount of blood ejected from the left ventricle each minute
Hypervolemia
Fluid overload
Stroke Volume
Amount of blood ejected from the left ventricle with each contraction
Afterload
Resistance to left ventricle ejection
Preload
End diastolic pressure
SA node speed
60-100 bpm
AV node speed
40-60 bpm
Purkinje Fibers speed
20-40 bpm
Atelectasis
collapse of the alveoli
Compliance
ability of the lungs to expand
Airway resistance
pressure difference between the mouth and alveoli related to the rate of gas exchange
Diffusion
Exchange of respiratory gases in the alveoli and capillaries
Pulmonary Edema
Lung or part of a lung filling/swelling with fluid
Perfusion
Blood flow to lungs and tissues
Hypovolemia
Low fluid volume
Esophageal varices
Extremely dilated submucosal veins in the esophagus. Similar to varicose veins in the esophagus.
Hyperventilation
Ventilation in excess of that required to eliminate carbon dioxide produced by cellular metabolism
Hypoventilation
Alveolar ventilation inadequate to meet the body’s oxygen demand or to eliminate sufficient carbon dioxide
Cyanosis
Blue discoloration of the skin and mucous membranes
Hypoxia
Inadequate tissue oxygenation at the cellular level
Acute Coronary Syndrome
Condition when blood supplied to the heart muscle is suddenly blocked
Angina Pectoris
Transient chest pain caused by imbalance between myocardial oxygen supply and demand
Apnea
absence of breathing
BiPAP
bilateral positive airway pressure
