1. cheyne stokes
2. bitots
3.kussmaul
4.apneustic

  #2

which one is normal if it occurs in infants or neonates ?

  #3

Kussmaul breathing: deep, regular breathing due to metabolic acidosis (diabetic acidosis & coma), and the rate may be fast, normal or slow

Apnea: cessation of respiration lasting from 2 to 60 second. Seen in Primary Respiratory disorders:Respiratory Distress syndrome, Bronchopulmonary dysplasia; Infection/Inflammation: Pertussis, Pneumonia, Septicemia, Meningitis, Bronchioloitis; Drug related: Drug withdrawal (maternal addiction), Early cessation of theophylline/aminophylline, Analgesic or anaesthetic drugs in labor; CNS: Convulsions, Intracranial haemorrhage: tentorial tear, intraventricular haemorrhage, subdural haemorrhage, cerebral edema; Gastrointestinal disorders: Gastroesophageal reflux; Cardiac disorders: congenital heart disease, cardiac conduction disorders (rare); Sleep apnea: enlarged tonsils and adenoids, extreme obesity (rare), narcolepsy (rare), primary alveolar hypoventilation (rare); Other: Hypoglycemia/Hypocalcaemia, Obstruction of the nasal airway by vomitus, milk, mucus, nasogastric feeding tube, meconium, choanal atresisa (rare), Other airway obstructions: transient obstruction at level of larynx, excessive flexion of neck, mandibular hypoplasia (Pierre-Robin syndrome), Preterm, Introduction of milk feed in preterm infants, Hypoxia: birth asphyxia, acute hypoxia, anaemia
Unpleasant stimulus, Low or high body temperature, Arnold-Chiari malformation/hydrocephalus/Inborn errors of metabolism (rare), Munchausen syndrome by proxy (rare)/Joubert syndrome (rare)

Biots’ Breathing: Characterized by several short breaths followed by long irregular periods of apnea. It is seen in increase intracranial pressure

Cheyne-Stokes respiration: periods of apnea of 10-20 sec separated by approximately equal periods of hyperventilation
This may be a normal pattern for children during sleep
. Seen in Severe heart disease; congestive heart failure, Brain damage (typically on both sides of the cerebral hemispheres of diencephalon), Uremia, Drug-induced respiratory depression, Increased intracranial pressure
