We examined the effect of no music, classical music or rock music on simulated patient monitoring. Twenty-four non-anaesthetist participants with high or low levels of musical training were trained to monitor visual and auditory displays of patients' vital signs. In nine anaesthesia test scenarios, participants were asked every 50-70 s whether one of five(More)
BACKGROUND In a full-scale anesthesia simulator study we examined the relative effectiveness of advanced auditory displays for respiratory and blood pressure monitoring and of head-mounted displays (HMDs) as supplements to standard intraoperative monitoring. METHODS Participants were 16 residents and attendings. While performing a reading-based distractor(More)
(2003). Operating theatre patient monitoring: The effects of self paced distracter tasks and experimental control on sonification evaluations. Abstract Three experiments were conducted to explore the effectiveness of continuous auditory displays, or sonifications, to convey information about simulated patient physiological state in dual task trials.(More)
1. The actions of ether and methoxyflurane on the evoked potentials of in vitro preparations of the guinea-pig olfactory cortex were studied. Following stimulation of the lateral olfactory tract (l.o.t.) evoked potentials could be recorded from the cortical surface; these potentials consisted of an initial wave (the compound action potential of the l.o.t.)(More)
Postoperative recovery from muscle weakness was investigated by handgrip strength after general anaesthesia using short- and long-acting muscle relaxants. Handgrip strength was measured on four occasions, preoperatively, before and after premedication, and postoperatively, both as soon as the patient could sustain a five-second headlift and one hour later.(More)
A simple hydraulic hand dynamometer was used to assess the hand grip force before and after general anesthesia. Eight patients received a general anesthetic of nitrous oxide and oxygen and an inhalational agent without relexants (non-relaxant group). Ten patients received a similar anesthetic of nitrous oxide and oxygen and an inhalational agent with(More)
McComas (1977) has published a method of estimating the number of motor units in human sketal muscle, based on peripheral nerve stimulation and recording of the surface electromyogram (EMG). One assumption of the method is that individual motor units, recruited by peripheral nerve stimulation just above threshold, give discrete observable increments to the(More)
