Anesthetic technicians assist the anesthetist with:

• waking the patient.by administration of reversal agent to access spontaneous recovery
• removing airway devices.
• transferring patients to post-operative care units

Regional variations exist, but anesthetic technicians may also be involved with:^[1][6]

• Airway establishment & management.
• Intra-operative intra-aortic balloon pump setup, operating and monitoring.
• Elective & Emergency Blood Management.
• Swan-Ganz pulmonary artery catheter insertion and monitoring.
• Intra-operative blood salvage setup, operating and monitoring.
• Drawing of blood Samples.
• Arterial blood gas analysis, including maintenance of analysers.
• Arterial line insertion and monitoring.
• Peripheral IV line insertion.
• Cardiopulmonary resuscitation.
• Central IV lines.
• TEG Sampling.
• Point of Care Analysis.

Anesthesia practice comes with a variety of physical, ergonomic, chemical, and biological risks in the workplace.^[7][8] The physical hazards associated with anesthesiology practice include noise exposure and ionizing radiation in the operating room.^[9][10][11] Anesthesia technicians also face ergonomic risks. In 2013, 85% of anesthesiologists reported having ergonomic inconveniences,^[7] and anesthesia technicians largely use the same equipment as anesthesiologists on top of having their own physically demanding responsibilities, such as restocking the anesthesia and setting up the equipment before operations.

Inadequate disposal of waste anesthetic gases is one of the most common mistakes in the practice.^[7] Outdated or inadequate ventilation systems results in continuous exposure. Nitrous oxide is one of the most common gases used when conducting anesthesia operations.^[7][9] Chronic exposure has many side effects depending on how long technicians are exposed for. Short term exposure can lead to nausea, dizziness, and decreased cognitive performance while long term may affect reproductive functions.^[12]

Anesthesia technicians are exposed to various infectious disease inside the clinical environment. Being in the vicinity of patients often leave technicians susceptible to airborne diseases such as Influenza and Coronavirus. Bloodborne disease also play significant role as hazards inside the work environment. Equipment, especially sharp objects, often graze or touch the technicians which can lead to infection of HIV or Hepatitis C. 25% of needlestick injuries occur inside operating rooms, with many reporting fatigue and high pressure environments.^[13]
