In this preliminary study, artificial respiration was produced in four anesthetized horses using trains of stimuli applied to long needle electrodes inserted bilaterally at the base of the neck. The needles were insulated to within 1 cm of the tips. The frequency of the stimuli (0.1 msec) was 35/sec and the train duration (duration of inspiration) was 1(More)
The threshold for ventricular fibrillation was determined in 12 pentobarbital anesthetized dogs using transthoracic electrodes located at the optimal axillary electroventilation sites. Electroventilation is the name used to designate inspiration produced by stimuli applied to body surface electrodes. The optimal stimulation site for electroventilation was(More)
During a previously published study on gaseous microemboli (GMEs) and perfusionist interventions, it was noted that emboli could be detected after the arterial filter when blood/air challenges entered the membrane oxygenator's integral cardiotomy. The findings indicated that further study into the oxygenator's integral cardiotomy reservoir was warranted.(More)
It is well known that extracorporeal surfaces have the ability to bind such drugs as fentanyl, nitroglycerine and propofol. Adsorption of the injectable anesthetic agent Diprivan (propofol) onto uncoated and heparin-coated extracorporeal surfaces during cardiopulmonary bypass (CPB) has been previously investigated; however, propofol adsorption onto(More)
