Anesthesia machines are equipment basically used to keep the patient unconscious when surgery is done. The equipment is equipped with ventilators capable of providing mechanical ventilation to patients with respiratory failure. By means of re-inhalation systems, these equipments have a circular internal circuit, which allows the partial reuse of the anesthetic gases exhaled by the patient. The common devices contain a fresh gas flow to administer the gas entering the circuit, in addition to adjustable limiting valves, to inspect the pressure inside the system, which allows the sweeping of waste gases, and a reservoir bag to store gas.

The anesthesia machine currently works with The elements, composed of safety systems, are the flow meters, vaporizers, gas supply, patient circuit including mechanical ventilator and monitoring associated with the patient. 

Steps of Using the Anesthesia Machine

To adjust and comply with the correct use of anesthesia machines, carefully monitor each patient’s needs with their medical condition, anesthetic reactions and surgical requirements. Also, not only must comfort be ensured during surgery, but also correct medical decisions must be made to protect the patient.

In addition, in order to comply with good management through the use of the anesthesia machine, the following steps should be followed:

• The anesthetist is the only one in charge with levels of experience to handle the anesthetic equipment.
• Test that a handheld breathing bag that holds all anesthesia machines is available.
• Place antimicrobial filters into the inspiratory and expiratory branches of the ventilator.
• Justify proper connection of gas measurement lines, antimicrobial filters and water trap.
• The ventilator should be located at a visible and audible distance from the assistance personnel.
• Use only controlled or assisted-controlled modes of mechanical ventilation.
• Adjust the APL valve to the level required by the patient.
• Continuous monitoring of the anesthetized patient.
• Measurement of vital values, constantly.
• Be alert before any visible and audible alarm.

It should be noted that the entire gas distribution procedure, cylinder, keys, pipes, hoses, etc., should be properly classified by the anesthesiologist to avoid irreparable errors, thus making a wrong connection and avoiding irreparable situations.

Functions of the Medical Personnel in charge of operating the Anesthesia Machine

Anesthesiologists are responsible for handling anesthesia machines, and administering the appropriate drugs to patients who require it, from the monitoring of the patient awake or with varying degrees of sedation, without anesthesia or with local anesthesia, to the realization of various types of peripheral blocks, neuraxial blocks or different types of general anesthesia (inhalation, total intravenous or a mixture of both).

Its activity has extended externally from the surgical ward, especially to radiological, hemodynamic, oncological, endoscopic and dental programs.

The training of health professionals within a team of specialists is essential for optimal results, for reducing perioperative morbidity and mortality of patients subjected to different anesthetic-surgical processes. The system for using anesthesia machines and technological evolution are becoming more complex, since the implementation of more anesthetic processes, both surgical and diagnostic, and analgesic techniques, demonstrate the need for a long training that adjusts to the pace of scientific and technical development. Thus, knowledge can be renewed to offer assistance with maximum effectiveness, quality and safety for the patient.
