Document Summary
Eupnea normal breathing, including a normal respiratory rate (12 -20 breaths per minute), depth, and rhythm. Tachypnea increased respiratory rate greater than 20 breaths per minute. Caused by hypoxia, fever, pain, or a central nervous system problem. Bradypnea decreased respiratory rate less than 12 breaths per minute. Caused by sleep, drugs, alcohol, and metabolic disorders. Hyperpnea increased respiratory rate, rhythm, and depth of breathing. Cheyne-stokes an abnormal breathing pattern with periods of progressively deeper breaths alternating with periods of shallow breathing and apnea. Biot"s breathing characterized by irregular periods of apnea alternating with periods in which four or five breaths of identical depth are taken. Cheyne-stokes except that each breath has the same depth. Increased respiratory rate and depth, with an irregular rhythm. This is a labored form of breathing that is usually associated with diabetic ketoacidosis.
