How can you avoid SARS CoV-2 contamination in an anesthetic machine?

Anesthetic machines are medical equipment used in hospitals and clinics to deliver anesthetic gases to a patient during a surgical process. These gases, among other things, inhibit the functioning of skeletal muscles. The diaphragm is the main muscle in inhalation. If this is inhibited, there will be a need to artificially ventilate the patient.

The SARS-COV2 pandemic triggered a series of alarms and led to the implementation of new logistics in the use of respiratory systems in health centers, including the anesthesia machine, to avoid contamination with this new respiratory virus, whose main transmission is by droplets and aerosols from the respiratory system, hence the relationship and the utmost importance of the anesthesiologist’s role in the management of patients with COVID-19.

Using an anesthetic machine

An anesthesia machine is an essential tool in the operating room, able to transport anesthesia to the patient, in addition to controlling their respiratory function. And using an anesthesia machine creates optimal and safe conditions for the work of surgeons, because modern anesthesia machines today allow to control a number of vital functions and still calculate particular dose ranges:

  • Heart rate.
  • Pressure in the airways.
  • Oxygen concentration and flow.
  • Automatic ventilation of the patient’s lungs.

Reasons to protect an anesthetic machine from contamination

There are two reasons to protect an anesthesia machine from contamination that could spread by a COVID-19 infected patient. First if the virus is allowed to enter the internal parts of the machine, the virus could be transmitted to the subsequent patient.

Second, the respiratory gases sampled for gas analysis can transmit the virus to other patients or health personnel when they leave the gas analyser if not handled properly.

What to do to prevent contamination of anesthesia machines?

The ideal is to place a high quality filter (HMEF) that have an antiviral and antibacterial filtration of 99.99%, between the respiratory circuit and the patient’s airway to protect the machine against contamination and also gases sampled for analysis. Heat and humidity exchange filters are the best option because they preserve the humidity of the airways and are manufactured to filter the sampled gas before entering the gas analyser.

The use of filters in the respiratory circuit is essential for two clear reasons: first, they allow to filter the air exhaled by the released patient to the environment reducing the risk of viral contamination, and second, it allows to heat and humidify passively the air inspired by the patient improving the tolerance and management of secretions.
