How often should an anesthesia machine be serviced?

Any machine with a rebreathing circuit must be inspected and serviced by an authorized anesthetic machine service provider annually. The Soda lime/Baralyme (CO2 absorbers) should be changed regularly; minimally this should occur at least once after every 12 hours of use.

How do you check an anesthesia machine?

Check the machine for leaks by covering the common gas outlet with your thumb. DO NOT maintain the pressure for long (as this may cause damage). The oxygen flow will drop from 4L/min and there should be an audible hiss from the high pressure relief valve.

How does an anesthesia machine work?

The anesthesia machine receives medical gases from a gas supply, controls the flow and reduces the pressure of desired gases to a safe level, vaporizes volatile anesthetics into the final gas mixture, and delivers the gases to a breathing circuit that is connected to the patient’s airway.

How do you calibrate an o2 sensor on an anesthesia machine?

For the galvanic oxygen sensor, calibrate to room air (the time to 90% response is 15-20 seconds, so if it takes longer than 40-60 seconds to read 21%, change the sensor). Then expose to 100% oxygen and ensure it reads close. You may recalibrate at 100%, but it is not necessary with all monitors.

What equipment is used for anesthesia?

The anaesthetic machine is not a machine that makes anaesthetics, but a complex collection of equipment. It has three major components: a gas mixing and delivery system; an anaesthetic breathing system (circuit) and a ventilator; and an array of monitors.

Who should check the Anaesthetic machine?

The anaesthetist has a responsibility to understand the function of anaesthetic equipment and to check it before use.

Why do we check the Anaesthetic machine?

Checking each component of anaesthesia machine for appropriate functioning prior to use is essential to ensure patient safety.

How to check the anesthesia machine checklist?

Basic Anesthesia Machine Checklist 1 Turn oxygen ON, if pressure is at or below 500 pounds per square inch it is time to open a second tank 2 Turn alarm ON 3 Turn scavenger ON

What do you need to know about the anesthesia gas machine?

Verify that there are no leaks in the gas supply lines between the flowmeters and the common gas outlet. The gas supply in this part of the anesthesia delivery system passes through the anesthetic vaporizer (s) on most anesthesia delivery systems.

What to do if your anesthesia machine has a leak?

Once the leak is found, dry the area, repair the problem, spray with water and check to be sure the leak is truly fixed. Repeat pressurizing the machine. If no leak has yet to be found continue to another part of the anesthesia machine following the above procedure until the leak is found and the machine is 100% functioning.

What do you need to know about anesthesia monitoring?

Standards for patient monitoring during anesthesia are clearly defined. The ability to conform to these standards should be confirmed for every anesthetic. The first step is to visually verify that the appropriate monitoring supplies (BP cuffs, oximetry probes, etc.) are available.
