What are the key functions of an aesthesia machine ?
Provide Oxygen and stable ventilation (if needed) to a patient.
Mix gases with anaesthetic gases.
Minimise anaesthesia related risk.
What features may be present in a block diagram for an anaesthesia machine ?
Gas pipelines
Flowmeters for each gas
Hypoxia guards
A vaporiser to mix gases
A common manifold (plumbing)
Common Gas Outlet (CGO)
Scavenging Circuit (to reduce gas waste )
Breathing Circuit
Disposal Tubing
Why do anaesthesia machines contain gas tanks ?
In the fail safe case of leaks in wall gas tubing so the patient can be still under anaesthesia.
What is the function of a vaporiser ?
What subsystems are found in modern anaesthetic machines ?
High Pressure System
Intermediate Pressure System.
Low Pressure System
What electrical components are used in an anaesthesia machine ?
Master Switch –> to turn on and off the electrical and pneumatic functions.
Power Failure Indicator
Reserve Power
Data communication
Electrical Outlets + Circuit Breakers.
What pressure does the gas coming from the low pressure system come into the patient ?
