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 |
