Use of Calibration
Use of Calibration
Testing and calibration (is preparation of a usable scale on a measuring instrument) of bio-medical equipment to ensure quality control in equipments by biomedical technicians who specifically trained to calibrate and maintain is becoming increasingly significant today. Testing and calibration of equipment ensures accuracy, effectiveness and long life of equipments, which ultimately enables one to achieve the highest degree of quality control. Any measuring equipment or device needs to be tested and checked for its accuracy and calibrated whenever the need arises. Testing is done in accordance to domestic standards, very often this means, in accordance with manufacturers specifications, for both safety and performance test. The test results need to be formally documented.
Anesthesia machines and vaporizers must be in good working condition to reduce anesthetic gas leaks, to have the best performance of scavenging equipment, and ensure the appropriate percentage of anesthetic is being delivered. Personnel must be trained in the proper use of anesthetic machines and vaporizers prior to operation. Each piece of equipment involved in the delivery of inhalant anesthetics should be evaluated regularly to assure its proper function and integrity.
All anesthetic vaporizers must have preventive maintenance performed at least annually by the biomedical technician. Preventive maintenance includes:
- Physical inspection for loose or missing screws, sharp edges, or loose connectors.
- Visual inspection for mechanical or electrical damage.
- Verify operation of safety interlock if applicable.
- Verify operation of hand wheel lock and release button.
- Verify hand wheel turns smoothly through entire range.
- Check Fill / Drain system operates properly and that there are no leaks.
- Verify concentration delivery accuracy at 0, 1, 3, & 5% settings using room temperature 100% Oxygen at 5 LPM flow is within manufacturer's specifications.
