Terminology Flashcards
anoxia
lack or absence of oxygen
apnea
no breathing
dyspnea
difficult or labored breathing. It is a symptom reflective of decreased ventilatory capacity and increased work of breathing.
eupnea
normal breathing at rest
hypercapnia
(hypercarbia) excess PaCO2 in blood. May be result of hypoventilation or diffuse bronchopulmonary disease (CO2 retention)
hypocapnia
(hypocarbia) low PaCO2 in blood. May be result of hyperventilation
hyperoxemia
higher than normal PO2 in blood
hypoxemia
lower than normal O2 concentration or pressure or saturation in the blood
hyperoxia
high O2 concentration, pressure, or saturation in lung, blood, or tissues
hyperpnea
increase in rate and depth of breathing in proportion to metabolic rate.
hypopnea
decrease in rate and depth of breathing compared to breathing at rest.
hypoventilation
decreased ventilation in regards to metabolic needs resulting in increased PaCO2 (hypercapnia) and decreased PaO2. (hypoxemia) May be result of decreased respiratory rate and/or tidal volume and may lead to respiratory acidosis.
hyperventilation
increased ventilation in excess of metabolic needs resulting in decreased PaCO2 (hypocapnia) and increased PaO2 (hyperoxemia). May be result of increased respiratory rate and/or tidal volume. Produces signs/sx of dizziness, numbness, tingling, may lead to respiratory alkalosis.
