Anesthesia Equipment & Instruments: Definitions & Principles of Practical Usage

Anesthesia equipment

Anesthesia, or anesthetic equipment, is a set of instruments and devices used in anesthesiology, which is the medical science or a branch of medicine that studies and applies or administers anesthetics. Probably, the most common part of anesthesia equipment is the anesthesia machine, also called Boyle’s machine (named after Henry Boyle, the British anesthesiologist, who in 1917 invented the machine’s original concept), which is a special medical device that consists of a ventilator, suction unit, and a patient monitoring device and is used primarily for supporting anesthesia administration to the patients.


Anesthesia Workstation vs. Portable Anesthesia Machine

Anesthesia machines can be of two main types: stationary or portable. Anesthesia workstations are common for hospitals, clinics, where they are under the most practical usage. The most popular type of anesthetic machine is a continuous-flow type, designed to provide a continuous and measured supply of gases (e.g. nitrous oxide or oxygen) mixed together with an anesthetic vapor concentration (e.g. isoflurane), and delivered to the patient at necessary flow and pressure. What concerns portable anesthesia machines, they are advantageous mainly in those practices or situations where portability and shortage of time are of primary importance. Portable anesthesia unit is a complete system which can used within workrooms, examination and labor rooms, and which combines all the basic components needed for a manual procedure anesthesia.

When choosing an anesthetic machine, it is important to pay attention to the features like quality and reliability of a device to be purchased. Exquisite performance and high performance are most viewed not only by buyers, but also by manufacturers who provide those machines, in order to meet the needs of the medical sphere in the most advanced medical technologies & solution. And thus we present you the list of the most reliable anesthesia machine manufacturers that have already gained a world reputation: Maquet (Sweden), Drager (Germany), Rajas Enterprise (India), Mindray (China), Heyer Medical (Germany), Siare (Italy), Hersill (Spain), Spacelabs Healthcare (USA), Penlon (UK), Oricare (USA), Okuman (Turkey), Foures SAS (France), Nison Instrument (Shanghai), F. Stephan (Germany), Landwind Medical (China), Dameca (Denmark), Comen (China) and others.

The Diversity of Anesthetic Equipment & Instruments

Except the equipment mentioned above, in the practice of anesthesia the following instruments are also used:

  • air filter (for filtering out dust particles or specific gases from the gas given to the patient);
  • anesthetic vaporizer (for vaporizing the anesthetic);
  • artificial resuscitator (for manual ventilation);
  • endoscope (for looking inside the esophagus, upper intestines, stomach, larynx, bile duct, bronchi-through the mouth, trachea);
  • endotracheal tube (for maintaining a patient, thus ensuring that air reaches the lungs for respiration);
  • epidural catheter (for administering drugs into the epidural space);
  • laryngeal mask airway (an alternative to an endotracheal tube);
  • laryngoscope (for viewing larynx (vocal cords, glottis, etc.);
  • mucus sucker (for cleaning (aspirating) the respiratory passage out of any fluid build-up, especially mucus);
  • nasal oxygen set (for delivering oxygen);
  • needles (for infusions, injections, etc.);
  • oxygen mask (for delivering oxygen or for administering gaseous or aerosolized drugs);
  • peripheral venous catheter (for delivering drugs or medication through a peripheral vein);
  • suction catheter (for removing secretions from the mouth, trachea and bronchi, oropharynx);
  • syringe (for injecting drugs).
