Eupnea - normal respiration. Is quiet, rhythmic, and effortless.
Apnea - absence of breathing
Dyspnea - short of air
hyperventilation that accompanies metabolic acidosis - Kussmaul's breathing
Marked rhythmic waxing and waning of respirations from very deep to very shallow with short
periods of apnea - Cheyne-Stokes respiration
Orthopnea - inability to breathe easily unless sitting up right or standing
Conditions that decrease cardiac output - Congestive heart failure and hypovolemia
Diagnostic studies for o2 - Pulmonary function tests, arterial blood gases, sputum specimens,
incentive spirometers
