Instrument Uses
Continuous-flow anaesthetic machine used to provide an measured and continuous supply of gases (oxygen, nitrous oxide, etc), mixed with an required concentration of anaesthetic vapour to the patient at a required pressure and rate; vide link
Variable performance devices & Fixed performance devices used to deliver oxygen in different ways; vide How do I administer Oxygen?
Anaesthetic vaporizers vaporises the anaesthetic
Oxygen mask delivering gases up to the nostrils to assist in oxygen intake or to administer aerosolized or gaseous drugs
Nasal oxygen set -do-
Guedel airways[3] hard part of the airway maintenance that connects the mouth part to the pharyngeal part
Suction catheter Suction catheters used to remove secretions from the mouth, oropharynx, trachea and bronchii
Water & sand weight bag
Artificial resuscitator (Bag valve mask) manual ventilation
Bain circuit respiratory maintenance circuit
Laryngoscope used to view larynx including the vocal cords, the glottis, etc
Endotracheal tube a tube introduced into the patient's trachea to maintain a patient to ensure that air reaches the lungs for respiration
Laryngeal mask airway (LMA) a less painful but less useful alternative to an endotracheal tube
Tracheostomy tube it is a metal or plastic tube used to keep an artificial opening in front of the neck into the trachea open to act as an alternative pathway for respiration; vide tracheostomy
Endoscopes to look inside the oesophagus, stomach, upper intestines, bile duct, larynx, trachea, bronchi-through the mouth
Eschmann stylet or Gum elastic bougie a flexible device introduced through the mouth during some intubation procedures; if the stylet is in the trachea, while passing in, gives a sensation of bumps and then finally stops going in at a point, it indicates that it was gliding over tracheal rings and has stopped at one of the bronchi (the patient may even cough during this time); if it goes into the oesophagus, it will not bump and neither will it stop going in; used to judge where the endotracheal tube has gone in[4]
Filters air filters - to filter out dust particles or certain gases from the gas being given to the patient
Needles for injections, infusions, etc.
Tuohy needle for epidural catheter insertion
Lumbar puncture needle / Epidural anesthesia set / Spinal needle used for puncturing into the spine (or cisterns or fontanelles of a new born) for cerebro-spinal fluid aspiration or for injection drugs, specially anesthetics in spinal blocks, epidurals, etc
Epidural catheter used to pass drugs into the epidural space
Syringe to inject drugs; larger ones can be used with mucus suckers
Mucus sucker to aspirate any fluid specially mucus from the respiratory passage
