Generally, full mechanical ventilation is only used if a very deep state of general anaesthesia is to be induced, and/or with a profoundly ill or injured patient. Induction of general anaesthesia usually results in apnea and requires ventilation until the drugs wear off and spontaneous breathing starts. In other words, ventilation may be needed ...
Anesthesia (American English) or anaesthesia (British English) is a state of controlled, temporary loss of sensation or awareness that is induced for medical or veterinary purposes. It may include some or all of analgesia (relief from or prevention of pain ), paralysis (muscle relaxation), amnesia (loss of memory), and unconsciousness .
Associate membership was open to paramedics and nurses which later again changed to offering full membership recognising the changing roles of these professions . [ 7 ] : 45 [ 8 ] In 1991, the organisation increased their involvement in educational aspects, making available residential courses covering pre-hospital care and resuscitation.
Anesthesiology, anaesthesiology or anaesthesia is the medical specialty concerned with the total perioperative care of patients before, during and after surgery. [1] It encompasses anesthesia, intensive care medicine, critical emergency medicine, and pain medicine. [2]
To determine the depth of anesthesia, the anesthetist relies on a series of physical signs of the patient. In 1847, John Snow (1813–1858) [1] and Francis Plomley [2] attempted to describe various stages of general anesthesia, but Guedel in 1937 described a detailed system which was generally accepted.

The second edition appeared in 1986, with total content filling more than 2400 pages spread over three separate volumes. Although it was criticized for lack of cross-referencing and noticeable differences in writing styles due to a higher number of contributors, Miller's Anesthesia soon became the "standard encyclopedic textbook of anesthesia".

General anaesthetics (or anesthetics) are often defined as compounds that induce a loss of consciousness in humans or loss of righting reflex in animals. Clinical definitions are also extended to include an induced coma that causes lack of awareness to painful stimuli, sufficient to facilitate surgical applications in clinical and veterinary practice.
The hypothesis correlates lipid solubility of an anaesthetic agent with potency (1/MAC) and suggests that onset of anaesthesia occurs when sufficient molecules of the anaesthetic agent have dissolved in the cell's lipid membranes, resulting in anaesthesia. Exceptions to the Meyer-Overton hypothesis can result from: convulsant property of an agent
