How to understand and read an Anesthesia Machine?

The anesthesia machine is a hospital equipment essentially used for general, regional and intravenous sedation and resuscitation, its mechanism is based on a mechanical ventilator, a breathing system, suction devices and patient monitoring instruments, through medicinal gases mixed with a concise concentration of anesthetic vapor, continuously at an appropriate pressure and flow rate.

Typically, the anesthesia machine consists of five main mechanisms, made up of elements and systems with their respective safety conditions, they are: gas supply, flowmeters, vaporizers, patient circuit which includes the mechanical ventilator and associated patient monitoring.

Functional characteristics of the anesthesia machine

Anesthesia machines have the following functional characteristics:

  • Fluxometers: are used to measure the quantities of a gas in circulation, and are identified by yellow, green and blue tones.
  • Vaporizers: keep volatile liquid vapors within the required anesthetic concentration. Connection is important to avoid leaks.
  • Regulator: Reduces the pressure of a gas, facilitating compression at a prolonged rate to control cylinder output at adequate and constant pressure, and normalizing gas flow.
  • Manometer: Calculates the ejection rate or flow of gas from the normalizer in liters per minute. It consists of a device designed to calculate the tension of aeriform fluids.
  • Jus: Circular or rectangular metal clamp-like device, with a zipper that can be adjusted and used to attach gas cylinders to the regulator or anesthesia machine. Inside, it has a piece that is ideally attached to the corresponding part of the cylinder valve.

It should be noted that the entire gas distribution system: cylinder, keys, hoses, pipes, etc., must be color-coded, and the connections between the gas source and the anesthesia machine are unique for each gas, thus avoiding incorrect connection and irreparable situations.

Anesthesia machine visual indicators

The anesthesia system captures the parameters of the controlled interval and the data is displayed by an external system for record-keeping purposes. The same are displayed by airway pressure, respiratory rate, minute volume, inspired and final CO2 concentration and inspired oxygen concentration. In addition, drugs administered, laboratory data and intra-operative events can only be added manually.

In addition, the recording of the respiratory system with mechanical ventilation in the use of anesthesia, It will allow the doctor to know the conditions, follow and monitor the patient, through numbers and / or graphs reflected in the monitor, which will bring safety, prevention and identification of certain complications. These parameters will be displayed on the anesthesia monitor screen, as waves or curves representing the patient’s values.

In addition, the anesthesia machine is equipped with audible and visual alarms, which establish a significant safety measure for the patient. These must be sufficiently sensitive to quickly manifest a critical event, depending on the risk of the situation and the urgency with which it needs to be handled.
