Apnoea, bradycardia, and oxygen saturation in preterm infants.
To analyse the effects of apnoea and bradycardia on the oxygen saturation (SaO2) of preterm infants and to make recommendations for apnoea alarm limits, polygraphic recordings were made on 89 occasions of 27 preterm infants; 1029 apnoeic episodes were analysed. Reduction in SaO2 was positively correlated with duration of apnoea, but the scatter of results was such that reductions in SaO2 of up ...
متن کاملSleep apnoea profile in preterm infants recovering from respiratory distress syndrome.
Polygraphic recordings were made on 10 preterm infants recovering from respiratory distress syndrome and 12 healthy preterm control infants at 40, 52, and 64 weeks' conceptual age to study the influence of respiratory distress syndrome on the development of the sleep apnoea profile. Two significant differences were found: infants with respiratory distress syndrome not only had a lower incidence...
متن کاملEffect of positioning on the breathing pattern of preterm infants.
Respiration, as judged by gas exchange and pulmonary function, is improved in preterm infants kept in the prone rather than the supine position. The influence of position on the breathing pattern as documented by the pneumogram was studied in 14 stable preterm infants with recent clinical apnoea. Ten of the infants had oximetry and nasal flow studies simultaneously with the impedance pneumogram...
متن کاملRelation between apnoea duration and type and neurological status of preterm infants.
The incidence, duration, and type of apnoea were determined in 28 preterm infants born at 27 to 34 weeks' gestation, using polygraphic records of abdominal breathing movements and nasal airflow. Of the 1520 episodes of apnoea of 10 or more seconds duration, 1002 (66%) lasted 10 to 14 seconds, 311 (20%) lasted 15 to 20 seconds, and 207 (14%) lasted more than 20 seconds. Overall, 69% were central...
متن کاملUpper airway patency during apnoea of prematurity.
Twenty four preterm infants (median birth weight 1120 g and gestation 29 weeks) were studied on 83 occasions by measuring upper airway airflow. Airway patency was detected by the transmission of cardiac impulse up the airway and airway closure by its absence. A total of 309 apnoeas of at least five seconds' duration were recorded. One hundred and eighty (58.0%) were central, 109 (35.5%) mixed, ...
