The measurement of gaseous exchange during nitrous oxide anaesthesia.
A method is described for the estimation of carbon dioxide output, oxygen uptake, and respiratory exchange ratio during nitrous oxide anaesthesia. The inspired and expired minute volumes are measured with a box-bag system, the carbon dioxide concentrations with a carbon dioxide sensitive electrode, and the oxygen concentrations with a polarograph. Carbon dioxide output can be measured with a co...
متن کاملRespiratory and Metabolic Changes during Methoxyflurane and Halothane Anaesthesia.
Respiratory and metabolic changes were studied in twenty normal children during inhalation of 1.5 per cent methoxyflurane or halothane. Both agents caused a significant reduction in pH, and this acidosis was entirely due to a raised Pco2. It was calculated that after 30 minutes anaesthesia the approximate arterial tension of methoxyflurane was 0.3 per cent and that of halothane 0.8 per cent. Si...
متن کاملActive inspiratory impedance and neuromuscular respiratory output during halothane anaesthesia in humans.
The aim of this study was to measure, in 11 patients with healthy lungs, active inspiratory impedance during anaesthesia. In addition, we recorded changes in inspiratory occlusion pressure at 100 ms (P0.1) and ventilatory pattern while awake and during anaesthesia with a mean inspiratory fraction (FI) of 0.017 halothane in O2. The total active inspiratory resistance and elastance values were 5....
متن کاملEffect of airway occlusion on respiratory timing during anaesthesia with enflurane or halothane.
Eighteen patients were studied, during operations under subarachnoid or extradural anaesthesia combined with general anaesthesia, to assess the influence of occlusion of inspiration on the duration of inspiration, and the likelihood of a relationship between lung volume and duration of inspiration. Ten patients breathed 2% enflurane and eight breathed 1% halothane, using 67% nitrous oxide in ox...
متن کاملHalothane anaesthesia in turkeys.
An anaesthetic technique employing halothane in oxygen for use in adult turkeys is described. The mixture was administered using a Magill attachment and a Hall cat mask. Induction was rapid and excitement-free. Anaesthesia was maintained for varying periods of time up to a maYimnm of 80 minutes. Recovery was rapid. In a total of twenty-five turkeys no deaths occurred which were attributable to ...
