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)
We reviewed the use of advanced display technologies for monitoring in anesthesia. Researchers are investigating displays that integrate information and that, in some cases, also deliver the results continuously to the anesthesiologist. Integrated visual displays reveal higher-order properties of patient state and speed in responding to events, but their(More)
We discuss the phenomenon of system tailoring in the context of data from an observational study of anaesthesia. We found that anaesthetists tailor their monitoring equipment so that the auditory alarms are more informative. However, the occurrence of tailoring by anaesthetists in the operating theatre was infrequent, even though the flexibility to tailor(More)
We investigate the effectiveness of sonification (continuous auditory display) for supporting patient monitoring while reducing visual attentional workload in the operating theatre. Non-anaesthetist participants performed a simple continuous arithmetic task while monitoring the status of a simulated anaesthetised patient , reporting the status of vital(More)
BACKGROUND Head-mounted displays (HMDs) can help anesthesiologists with intraoperative monitoring by keeping patients' vital signs within view at all times, even while the anesthesiologist is busy performing procedures or unable to see the monitor. The anesthesia literature suggests that there are advantages of HMD use, but research into head-up displays in(More)
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)
(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)
The operating theatre is a noisy place with many uninformative and redundant alarms. Using data from a recent observational study, we demonstrate that anaesthetists actively respond to only 3.4% of all audible alarms. We outline a range of possible solutions to the alarm problem. Ecological Interface Design (EID) helps to outline the requirements for an(More)
The relative potency of lignocaine, bupivacaine and etidocaine was estimated by forearm skin weals in four volunteers. Potency was estimated as the time to half-recovery of a sharp sensation in response to a needle-prick. The increase in duration of action with increased concentration was greater for bupivacaine and etidocaine as compared with lignocaine.(More)
