What is the difference between passive, semi-active and active scavenging system?
Passive is: The most reliable with the least maintenance solution as a scavenging system.
Semi-active is: An interface connected to each anesthesia machine.
Active is: A system consisting of an interface on each anesthesia machine connected to a blower assembly.
Passive is: Charcoal filters and a tube connecting the anesthesia machine to the exterior of the building.
Semi-active is: A blower assembly system with scavenger interfaces at every anesthesia machine that allow the unused gases during anesthesia to be evacuated.
Active is: One central vacuum pump and a scavenger interface for each anesthesia machine.
Passive is: One central vacuum pump and a scavenger interface for each anesthesia machine.
Semi-active is: A blower assembly system that allows the gases used during anesthesia to be evacuated.
Active is: charcoal filters and a tube connecting the anesthesia machine to the exterior of the building.
Can you find the right affirmations on the Universal F circuit and the Coaxial circuit?
A. The Universal F circuit has 2 independent connections, one for inspiration and one for expiration. The Coaxial circuit increases breathing resistance of the patient.
B. When the patient exhales into the Universal F circuit and the gas changes direction, it increases breathing resistance. The Coaxial circuit has 2 independent connections one for inspiration one for expiration.
C. A disadvantage of the Universal F circuit is that it is possible to connect the circuits on the wrong ports. One of the advantages of the Universal F circuit and the Coaxial circuit is that when the patient exhales the warmer exhaled gas partially preheat the inhaled gases.
D. The Coaxial circuit consists of a tube within a tube. One goes on the inhalation port and the other one on the exhalation port. The inhalation travels through the center tubes up to the patient. The Universal F circuit has less breathing resistance compared to the Coaxial circuit.
