The 3-T valve is constructed of clear plastic to allow the surgeon and perfusionist
to view its status at all times.
"Then the surgeons do their magic," says Holt, "while the perfusionist
manages the patient's lungs and bloodflow using the heart-lung machine."
The questionnaire mainly comprised structured questions and a validated 10-item instrument specifically developed to measure job satisfaction among the perfusionists
; the Yildirim-Kaptanoglu and Demir Job Satisfaction Scale (KDJS), which discloses and measures the areas that are essential for perfusionist
comes from the Latin for "pour through." The diversion of the patient's blodd through the heart-lung machine during surgery is termed "extracorporeal circulation," extracorporeal being Latin for "outside the body." Perfusionists
practice extracorporeal technology.
The surgeon, surgical nurses and the perfusionist
look at the technical side and we look after the medical part.

(operator of an oxygenator) waits at his machine, which will empty all the blood from the patient into the heart-lung machine, oxygenate it and then send it circulating back into the baby's body.

The mean perfusion pressure was maintained at 70 to 90 mmHg where possible by small boluses of phenylepherine (100 [micro]g) and sodium nitroprusside infusion at the discretion of the perfusionist
. Systemic temperature was permitted to drift to 28[degrees]C during CPB and patients were actively rewarmed to 36[degrees]C before separation from CPB.
