The Critical Incident Technique was used to study anaesthetics given in a major tertiary care teaching hospital in order to define indications for monitoring with a pulse oximeter during anaesthesia. Anaesthetists were asked to use a pulse oximeter in every case and trained to report Critical Incidents in order to determine if the oximeter can shorten the(More)
Pulmonary hemodynamics and gas exchange were studied in four physicians during 72 hr acclimatization to 12,470 ft. Pulmonary catheters were left in three subjects for 72 hr. Resting mean pulmonary arterial pressure (PAP) rose progressively during the first 24 hr from 10.3 +/-1.0 to 21.1 +/-4.0 torr and remained at this level. During this same 24 hr period(More)
Lung areas with a low V/Q ratio cause hypoxaemia. The low alveolar oxygen concentration may cause local hypoxic pulmonary vasoconstriction (HPV) which reduces perfusion, raises the V/Q ratio, and hence reduces the tendency to a low PaO2. By changing PCO2, the HPV response can be altered. We examined this relationship in anaesthetized dogs by using a(More)
Narrow diameter implants are a lower cost alternative to conventional implants and are used to retain mandibular dentures. The experiences at a dental school predoctoral clinic are reviewed. The cumulative success rate for 626 fixtures placed in a six-year period is 92.6 percent with high patient satisfaction. Narrow diameter implants are a useful adjunct(More)
Previous papers have evaluated extravascular thermal volume of the lung (ETVL) as a measure of lung water by using median transit time (tmed) rather than the correct mean transit time (tmean). Calculation of ETVL using tmean (ETVLmean) and tmed (ETVLmed) gave an excellent relationship, ETVLmean = 1.48 ETVLmed - 0.74 (r = 0.99). This allowed us to calculate(More)
