ANESTHESIA MACHINE EXAM 1 QUESTIONS WITH CORRECT ANSWERS

ANESTHESIA MACHINE EXAM 1 QUESTIONS WITH CORRECT ANSWERS There are two gas supply systems - the ? which consists of cylinders and the ? which consists of the pipeline - Answers High pressure supply system; intermediate pressure supply system This system supplies gas from the cylinder and is used for emergency and when the pipeline is unavailable (i.e. traveling out of the OR) - Answers High pressure supply system Safety system that uses geometric features on the yoke to ensure that pneumatic connections between a gas cylinder and a machine that uses pressurized gases are not connected to the wrong gas yoke - Answers Pin index safety system (PISS) The PSI of a full oxygen E cylinder is ? - Answers 1900 psi The PSI of a full nitrous oxide E cylinder is? - Answers 745 psi This system is the primary source of gas that delivers gases at 50 psig. It has gas hoses that connect the gas inlet to the machine - Answers Intermediate supply pressure The pipeline system (intermediate supply pressure) delivers gases at ? psig - Answers 50 psig A ? shows us pipeline and cylinder pressures found on the front of the machine (nitrous oxide, oxygen, air) - Answers Bourdon tube/gauge Located underneath the anesthesia machine. This reduces cylinder pressures to 45 psig. They do not reduce pipeline pressures (which enter at 50 psig). The higher gas pressure will have preferential flow (pipeline). - Answers Primary pressure regulator The primary pressure regulator reduces cylinder pressures to ? - Answers 45 psig Located underneath the anesthesia machine. This device prevents hypoxia by detecting oxygen pressures and alarms with decreased pressure. - Answers Oxygen pressure failure device This device reduces pressures even further. It reduces oxygen pressure to 14 psig and nitrous oxide pressure to 26 psig. It supplies constant pressure to the flow control valves. - Answers Secondary pressure regulator The secondary pressure regulator reduces oxygen pressure to ? psig and nitrous oxide pressure to ? psig. - Answers 14; 26 This system consists of flow control valves to the common gas outlet. Includes flowmeter tubes, flow control valves, vaporizers, and check valve. - Answers Low pressure system The ? allows for precise control of gases to the common gas outlet. - Answers Flowmeters/flow control valves Floats or bobbins are different gas indicators. All types are read at the ?, except for the ball type, which is read at the ? - Answers Top; middle The ? is a proportion limiting control that prevents other gas flow without oxygen flow. It prevents a hypoxic mixture of gas. - Answers Hypoxic guard The ? helps change anesthetic agents from a liquid state to a gaseous state, regardless of temperature or gas flow rate. It is controlled by a single calibrated control knob. It is agent specific - each gas has its own. - Answers Vaporizer The ? receives all gases and vapor, including fresh gas flow (FGF). It delivers the gas mixture to the breathing system. - Answers Common gas outlet (CGO) The ? is an emergency oxygen supply that goes directly to the common gas outlet at a flow rate of 35 to 75 liters per minute. It bypasses the vaporizer, going straight to the CGO. - Answers Oxygen flush valve The ? begins at the fresh gas inlet and ends at the point gas enters the scavenger system. Its function is to provide anesthetic gases to the patient and eliminate carbon dioxide. - Answers Breathing circuit INSPIRATION:
