The anaesthesia machine mixes the correct concentrations of gas and drugs to be inhaled and exhaled
by the patient so they lose consciousness. They are held unconscious and have no sensation while being
operated on, then regain consciousness after the operation.
Physiology Anaesthetic gas affects the nervous system, resulting in a numbing of the nerve pathways. The patient
becomes unconscious, unaware of what is happening, has no pain, is immobile (may need breathing
support) and free from memory while under the influence of the anaesthetic agent.
How it works Air, Oxygen, and Nitrous Oxide are supplied from wall outlets or cylinders. The pressures are reduced by
pressure regulators then pass through an O2 failure alarm. The flow of gas is controlled by flowmeters.
The gas is mixed and passed over a vaporiser containing the anaesthetic agent. An Anti-hypoxic device
ensures that the flowmeters deliver a minimum of 25% O2 to the agent vaporiser. The gas then goes
through an over pressure relief valve and back flow valve, then to the common gas outlet (CGO), ready to
be given to the patient.
There is an emergency O2 flush valve connected to give 100% O2 if required. The gas then enters a
patient circuit and ventilator. Expired gas can be stripped of CO2 in a soda-lime filter and recirculated, or
scavenged out of the room.
Units of
measurement
Flow: L/min, Pressure: kPa and cmH2O
Typical values Dependant on patient size, rate and strength of breathing, circulation and solubility of the anaesthetic.

Do you stop breathing under general anaesthetic?
yes that is why u are put on a machine called a ventilator it breathes for u
Do Arthrograms hurt?
Yes - and no... The procedure involves an injection of 'dye' into the joint to provide a contrast for an e-ray machine or ultrasound. The injection is usually done after a local anaesthetic has been administered. The initial injection of anaesthetic can be felt as a sharp prick - but takes seconds to work. The needle used for the main procedure shouldn't be felt, as the area should be numb.
