The tube is then secured to the face or neck and connected to a T-piece, anesthesia breathing circuit, bag valve mask device, or a mechanical ventilator. Once there is no longer a need for ventilatory assistance or protection of the airway, the tracheal tube is removed; this is referred to as extubation of the trachea (or decannulation, in the ...
General anaesthesia (UK) or general anesthesia (US) is a method of medically inducing loss of consciousness that renders a patient unarousable even with painful stimuli. [5] This effect is achieved by administering either intravenous or inhalational general anaesthetic medications, which often act in combination with an analgesic and ...
It channels oxygen and inhalational anaesthetic to the lungs. It can be used during anaesthesia, or while a patient is unconscious. Laryngeal mask airways are designed to be an easy way to secure the airway and ventilate a patient – they are easier to place than tracheal intubation due to the lack of muscle relaxants and laryngoscopy.
This procedure is used where general anesthesia must be induced before the patient has had time to fast long enough to empty the stomach; where the patient has a condition that makes aspiration more likely during induction of anesthesia, regardless of how long they have fasted (such as gastroesophageal reflux disease or advanced pregnancy); or where the patient has become unable to protect ...
General anesthesia does not always require the anesthetic machine, tested daily, as basic equipment. Anesthesia machines may differ in appearance, size and degree of sophistication but generally speaking, they consist of sections for: ventilation; Peripheral Nerve Stimulator; space for monitoring equipment; accessories; storage space; worktop
[20] [23] A tracheostomy tube can be placed through the opening created by the incision, which allows breathing through the tube rather than the nose and mouth. [ 20 ] [ 24 ] Although the terms are sometimes used interchangeably, a " tracheotomy " is the surgical procedure creating an incision into the trachea, while " tracheostomy " refers to ...

In general, features of an ideal supraglottic airway include the ability to bypass the upper airway, produce low airway resistance, allow both positive pressure as well as spontaneous ventilation, protect the respiratory tract from gastric and nasal secretions, be easily inserted by even a nonspecialist, produce high first-time insertion rate ...
