CVR Flashcards
Clinical measures: preload
end-diastolic pressure
end-diastolic volume
right atrial pressure
Define minute ventilation
Volume of air expired in one min
Define alveoli ventilation
Volume of air reaching respiratory zone per min
Define respiration
Process of generating ATP either with an excess or shortfall of oxygen
Define anatomical dead space
Capacity of airway incapable of undertaking gas exchange
Define alveoli dead space
Airways that should be able to undergo gas exchange but cannot
Define Physiological dead space
Sum of alveoli and anatomical dead space
Define Hypoventilation
Deficient ventilation- acidosis, unable to meet metabolic demand
Define hyperventilation
Excessive ventilation. Atop of metabolic demand. Alkalosis
Define hyperpnoea
Increase depth of breathing
Define hypopnoea
Decrease depth of breathing
Define apnoea
Cessation of breathing. No air movement
Define Dyspnoea
Difficulty in breathing
clinical measures- afterload
systolic blood pressure
dalton law
pressure of gas mixture = sum of pp of all gases in that mixture
