Miniturizing the pediatric circuit / Pediatric Test 2 Flashcards
Surface coatings have been shown to reduce
inflammatory responses to CPB as well as maintain better platelet function
VAVD has been shown to
increase the risk of air embolization
Circuit condensation can be accomplished by both product design as well as clinical techniques such as?
RAP
Miniaturizing circuit has been shown to reduce what ?
SIRS
Incidence of blood transfusions
More and more perfusionists are beginning to route suction blood away from the circuit. This practice has been shown to reduce what ?
lipid embolization as well as white blood cell activation.
Active cooling has been linked to
platelet activation
With the increased usage of cerebral monitoring, in tandem with continuous blood gas monitoring, CCP’s are now able to increase or decrease cerebral blood flow by doing what ?
changing PaCO2, based on the clinical needs or risks.
3 Motivations for circuit miniaturization
Avoidance of donor blood
Avoidance of hemodilution
Reduction of synthetic surface area
