oxygenation in adults under general anaesthesia using Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE)- A physiological study," British Journal of Anaesthesia, vol.
In SDB, termination of apnoeic
episodes is accompanied by a sudden and brief arousal from sleep, with an accompanying increase in sympathetic activity, reduction in vagal tone, and resultant peripheral vasoconstriction [5, 12].
Of these, apnoeic
group consisted of 18 patients who had AHI > 5/h (female 6, male 12) while the remaining 32 were non-apnoeic with AHI <5/h (female 11, male 21).
Eisler's assertion "that sleep [is] a regressive phenomenon, a return to hypothetical preoral or apnoeic
stage, such as might be imagined for the unborn child" (419).
The incidence of hoarse cry, laryngospasm, apnoeic
spell, number of episodes of vomiting, time for first oral intake and any other complications in first 24 hours were recorded by an anaesthesiologist who was blinded to group allocation.
Aspiration pneumonia, respiratory distress, apnoeic
spells, hypoglycaemia and jaundice were recorded complications.
However, such practice of sudden temperature crash from hyperthermia to hypothermia and a quick buildup back to hyperthermia without any obvious thermal stability creates a condition of neonatal "thermal shock" that could readily initiate apnoeic
Intermittent positive pressure ventilation (IPPV) of an apnoeic
patient is an essential part of respiratory support in anaesthesia and resuscitation.

The removal of the wakefulness drive to breathe renders ventilation dependent on the prevailing chemical stimuli and unmasks a highly sensitive hypocapnic apnoeic
Secondly, closure of the airway and an apnoeic
interval during the pharyngeal phase prevents the bolus being sucked towards the negative pressure within the airway and finally, the sequential stripping action of the superior, middle and inferior pharyngeal constrictors moves the bolus into the upper oesophagus.
He suffers from serious respiratory problems, including apnoeic
attacks - an involuntary halt to breathing.
