Anesthetic care is provided using an anesthesia machine and integrated monitors (ie, the anesthesia workstation (figure 1)) that include systems for:

Blending a precision mixture of respiratory and anesthetic gases (anesthesia machine and vaporizers)

Dispensing those gases to the patient (anesthesia breathing system)

Delivering positive pressure ventilation (anesthesia ventilator)

Removing waste gases (scavenger system)
