this type of respiration consists of a deep breathing in with a wide open mouth and retracting of hte tongue and head; sometimes a smacking sound is heard; occurs in irregular intervals with periods of arrest. Often occurs in premature babies as their condition deteriorates or follows situations in which a great deal of energy is expended
gasping or snatch
this respiration pattern includes slowly increasing or decreasing respiratory excursions that are separated by respiratory arrest; it is frequently seen in premature infants; in the mature infant, efforts of feeding, vomiting, crying, etc. may result in temporary pattern; includes Cheyne-Stokes breathing pattern

(2) arrest of respiration accompanied by groaning or wheezing
(3) rapid expiration
this type of breathing is the oldest and most primitive form of air breathin; can be learned and used by patients with respiratory muscle paralysis' as a form of emergency breathing, small amounts of air are taken into the mouth and larynx, the lips are pressed together, and the soft palate is lifted to let the air pass; the air is presed through the pharynx with the aid of the tongue and cheeks

irregular respiration
this respiration is characterized by visible lowering of the jaw during inspiration, mouth open, tongue raised and lowered, jugular retractions, intercostal and epigastric reactions, snoring or gargling sounds and stridor; calvicular breathing may accompany; usually associated with obstruction of the upper airway, pneumonia, whooping cough, micrognathia or severe CNS dysfunction

thoracic respiration
at what age do you commonly see a child practicing thoracic respiration?
7 years and older
what is the common respiratory rate for a child practicing abdominal/diaphragmatic respiration as a term infant?
35-40 breaths per minute
