ANZCA Fellowship Equipment and Safety Exam 2025 Questions and Answers 2022A14 Safety precautions and equipment requirements for providing anaesthesia in MRI - ....ANSWER☑️☑️...-MRI uses magnetic fields and radiowaves to image hydrogen atoms abundant in fat and water. Numerous safety and equipment precautions must be taken to ensure safe anaesthesia care EQUIPMENT REQUIREMENTS - Must be MR safe or conditional - "Safe" equipment poses no additional hazard in any MR environment - "Conditional" equipment may have limits on static field strength, spatial gradient and rate of change of magnetic field that it can be used with - "Unsafe" equipment poses a hazard in any MR environment and must not be used - All monitoring and anaesthetic equipment must conform to operating theatre and MR safety standards - E.g. Reports of burns from standard pulse oximeters, so fibreoptic and MRI-safe oximeters are preferable, transmit signals via light vs electrical current - Monitoring equipment should be kept outside the scanning room, meaning cables that are required are long (invasive arterial line, capnography sampling line- which can lead to damping, or delays in displayed waveform) FOR STUDY PURPOSES ONLY ©️ 2025 ALL RIGHTS RESERVED 1
