Anesthesia Machine Available in Kenya

Most people are familiar with the word anesthesia. It is a collective word for taking painkillers and being sedated during surgery. It is a significant medical advancement that benefits both patients and physicians. Anesthesia refers to a loss of pain perception, particularly when it is brought on artificially through the ingestion of medications or the delivery of gases. It makes it possible for patients to endure surgery painlessly. Before the discovery of painkillers, people used to have to put up with the agony of surgery, which could range from minor to agonizing. With anesthesia, doctors and surgeons may complete their work without being interrupted by a patient writhing in pain or trying to flee from it.


  • Pipeline and cylinders for gas delivery
  • Gas and vapor flow that is controlled by vaporizers and flowmeters
  • Gas delivery: ventilator and breathing apparatus
  • Scavenging for waste gases
  • Monitoring

Working Principle

The main duties of an anesthesia machine are to deliver oxygen and anesthetic gases, remove carbon dioxide from the respiratory system, and provide controlled ventilation. It is crucial to comprehend how the anesthetic machine works to ensure proper utilization. Most veterinary clinics obtain oxygen and other medicinal gases from compressed gas cylinders. These cylinders come in the two most popular sizes, H and E. Roughly 700 liters of oxygen can be found in an E cylinder, and about 7,000 liters can be found in a cylinder. Both have a pressure of 2,200 pounds per square inch when fully inflated.

The components of an anesthetic machine known as breathing circuits are responsible for providing a patient with the necessary gasses and then getting rid of the CO2 they exhale. They are essential in describing how this device operates. The circle and non-rebreathing circuits are the two different types of breathing circuits. Non-rebreathing circuits work just as they sound; the patient does not rebreathe the gases once they have been expelled from the body. The opposite is true with circle circuits; they take away the CO2 the patient exhales while allowing the rebreathing of the anesthetic gasses. Vaporizers assist in precisely adjusting the anesthetic dosage within a breathing system. The vaporizer in most machines receives the entire gas flow and divides the fresh gas into a


  • Scavenging system: This keeps the machine from contaminating the nearby atmosphere by removing any extra gases. The other persons in the room may suffer if gases escape the space.
  • Heads-up display - A monitor on the apparatus enables medical professionals to keep track of the gas flow and ensure that it remains steady. The technician will be informed of any flow changes when they appear on the screen.
  • Source of oxygen: Unconscious Patients will need assistance breathing. Therefore oxygen is crucial. Depending on where the procedure will take place, the room may have pressurized air tanks or airlines flowing through it.
  • Oxygen flowmeter: The flowmeter maintains a constant flow of oxygen. Most machines use electronic proportional control valves that maintain consistency since the airflow must be consistent.
  • Vaporizer: The vaporizer turns the anesthetic's liquid form into a vapor in which the patient can breathe.
  • The anesthesia is frequently administered to the patient using a face mask that covers their mouth and nose, along with a hose. This is known as the patient's breathing circuit.

Product issues and how to solve them

In the event of a power outage

The pipeline gases can be turned off for at least 45 minutes while there is battery backup - If the pipeline gas supply is turned on and the workstation power supply is the only source of power loss, this can be extended by up to 90 minutes. A safety oxygen valve that can deliver 0–12 liters of oxygen via the closed circuit "Y" piece has been supplied in the case of battery failure or battery exhaustion.

Gases are not delivered via the open circuit. It uses manual ventilation as its way of operation. Based on their dial concentration, volatile anesthetic drugs can be administered concurrently. The Primus machine might act like a simple Boyles machine with only a pneumatic component.

When the cylinder is accidentally left open:

  • The machine preferentially uses the pipeline line oxygen. It does not use the oxygen in the cylinder when the pipeline supply is on, and the oxygen and nitrous oxide (N2O) cylinders are also open.


Additional safety elements and a computerized safety self-checkout mechanism activated at startup are built into this cutting-edge anesthetic equipment. Before every case, this should be reviewed again; ideally, it should be noticed. However, it can only be gotten around in an emergency several times. Pre-use inspection and regular maintenance are essential to preventing accidents caused by machine malfunctions.
