TermDefinition
Eupnea normal breathing
Dyspnea difficult or labored breathing
Apnea not breathing
Bradypnea abnormally slow breathing
Tachypnea very rapid breathing (increased f)
Orthopnea dyspnea experienced only while supine, may be associated with CHF, asthma, or anxiety
Hyperpnea increased ventilation during exercise—increased f & Increased TV = increased total minute ventilation. Ventilation increases to meet metabolic needs
Hyperventilation increased ventilation beyond metabolic needs, decreased arterial CO2 (PaCO2) & increased arterial O2 (PaO2)
Hypoventilation ventilation which does not meet metabolic needs, increased PaCO2 and decreased PaO2
Apneustic breathing prolonged periods of inspiration followed by short, abrupt expirations
Kussmaul breathing rapid, deep breathing observed in diabetic acidosis
Cheyne-Stokes breathing a form of periodic breathing characterized by cycles of gradually increasing f and increasing TV, followed by a gradual decrease in both f & depth of breathing
Biot’s breathing a form of periodic breathing characterized by irregular periods of apnea alternating with periods in which four or five breaths of identical depth are taken
Cyanosis bluish discoloration due to deoxy-hemoglobin concentration in excess of 5gm/100gm of blood or O2 sat decreasing to 83% in a person with normal Hgb concentration
Hypoxia decreased amount of O2 at the tissue level
Hypoxemia decreased amount of O2 in the arterial blood
Hypercapnia (hypercarbia) an excess of CO2 in the blood
Hypocapnia (hypocarbia) a deficiency of CO2 in the blood
Hyperoxia O2 levels above 21%
Atelectasis collapse of alveolar units
Hyperinflation increased air I the lungs, such as seen in emphysema or severe asthma, FRC is increased
