Anesthesia Machine and Its Parts: A Complete Guide
Introduction
An anesthesia machine and its parts play a critical role in modern medical practice. This equipment delivers a continuous supply of medical gases, mixed with anesthetic vapors, to patients during surgical procedures. A proper understanding of the anesthesia machine anatomy and its accessories ensures safety, efficiency, and better patient care.
In this guide, you will find a detailed explanation of the anaesthetic machine explained step by step, including essential accessories and commonly used terms such as what an anesthesia machine is also known as in different medical contexts.
What is an Anesthesia Machine?
An anesthesia is a medical device that delivers controlled concentrations of oxygen, nitrous oxide, and anesthetic agents to patients. It provides ventilation support, monitors breathing parameters, and ensures a safe environment during surgeries.
Anesthesia machine also known as:
- Anaesthetic machine
- Gas machine
- Boyle’s machine (traditional name)
- Anesthesia workstation
Anesthesia Machine Anatomy
The anesthesia anatomy includes several major components, each designed to maintain precision, safety, and functionality. Below is a detailed breakdown of the anesthesia and its parts.
1. Gas Supply System
- Oxygen, nitrous oxide, and medical air sources
- Pressure gauges to monitor flow
- Pipelines and cylinders
2. Flowmeters
- Measure the amount of gas flow
- Oxygen flowmeter marked with safety features
- Ensures precise gas delivery
3. Vaporizers
- Convert liquid anesthetic agents into vapor
- Control concentration for inhalation
- Temperature-compensated design for accuracy
4. Breathing Circuit
- Connects the machine to the patient
- Includes tubing, inspiratory, and expiratory valves
- Maintains a closed or semi-closed breathing system
5. Ventilator
- Provides mechanical breathing
- Adjusts tidal volume, respiratory rate, and pressure
- Essential during long or complex surgeries
6. Scavenging System
- Removes excess gases from the operating room
- Maintains environmental safety
- Protects healthcare professionals
7. Monitoring Devices
- Oxygen analyzers
- Pressure alarms
- Capnography for CO₂ monitoring
