Changes in arterial oxygenation and physiological deadspace under anaesthesia.
The changes in lung function commonly associated with anaesthesia and spontaneous or controlled ventilation are a reduction in lung compliance, an increase in physiological deadspace and an increase in alveolar-arterial oxygen tension difference. In 1959 Mead and Collier showed that there was a progressive fall in lung compliance in anaesthetized dogs whether ventilation was spontaneous or cont...
متن کاملThe effect of extradural analgesia combined with light general anaesthesia and spontaneous ventilation on arterial blood-gases and physiological deadspace.
Arterial Po2 and Pco2 were measured at half-hourly intervals in eleven patients anaesthetized for lower limb vascular surgery with a combination of nitrous oxide 67% and halothane 0.3-0.5% in oxygen, and an extradural injection of bupivacaine. Values for the alveolar-arterial oxygen tension difference, physiological deadspace and deadspace-tidal volume ratio were calculated. Although both the a...
متن کاملRelationship between alveolar deadspace and arterial oxygenation in children with congenital cardiac disease.
Fifty-eight children were studied during nitrous oxide in oxygen and fentanyl anaesthesia before undergoing closed or open cardiac surgery. FlO2 was 0.5. Alveolar deadspace was measured using the carbon dioxide single breath test (SBT-CO2) obtained from a computerized online system for monitoring expired CO2 and airway flow, based on the Servo ventilator, Arterial blood was sampled simultaneous...
متن کاملChanges in the electroencephalogram during anaesthesia and their physiological basis.
The use of EEG monitors to assess the level of hypnosis during anaesthesia has become widespread. Anaesthetists, however, do not usually observe the raw EEG data: they generally pay attention only to the Bispectral Index (BIS™) and other indices calculated by EEG monitors. This abstracted information only partially characterizes EEG features. To properly appreciate the availability and reliabil...
