Anesthesia Machine - ✔✔this machine receives oxygen and nitrous oxide from the supply lines, and
through the use of flow meters or valves on the machine, provides these games to the patient
what does an oxygen analyzer do? - ✔✔it measures the exact amount of oxygen in the mixture being
delivered to the patient
at what level will an alarm sound to warn of unsafe mixture of gases? - ✔✔20%
Vaporizer - ✔✔device that heats a liquid and releases it into the air in the form of steam
Ventilator - ✔✔device that breathes for the patient
what should an anesthetic system have when a ventilator is in use? - ✔✔a high and low pressure alarm
at what percent will an anesthesia machine stop delivering nitrous or other gases automatically when
oxygen is below a safe level? - ✔✔30%
how often should flow meters, reservoir bags and delivery tube be checked? - ✔✔daily
why should you check flow meters, reservoir bags and delivery tubes daily? - ✔✔to check for leaks and
patency
Scavenging system - ✔✔a means for reducing the levels of these noxious agents to an acceptably low
level by exhausting the outside the operating room
when should anesthetic gases be shut off? - ✔✔after the last patient
what will a full oxygen tank read? - ✔✔2000 psi
, what will a full nitrous oxide tank read? - ✔✔750 psi and will remain there until almost empty
Head tilt/chin lift - ✔✔the airway is maintained throughout the procedure by using a head tilt, using the
chin for titling the head
Jaw thrust - ✔✔protruding the jaw by using bimanual pressure to push to angles of the lower jaw
forward
Nasal mask or hood - ✔✔covers the nose only
nasal prongs/cannula - ✔✔inserted into the nares to delivery oxygen without covering the nose
suction - ✔✔the process of withdrawing or sucking up fluid; should be available in operatories and
recovery
back-up system - ✔✔additional suction source should be ready that is powered by water, gas or some
non-electric source in case of power failure
what is the initial intervention in the event of an airway emergency? - ✔✔bag/valve/mask ventilation
what does bag/valve/mask ventilation depend on? - ✔✔mandibular positioning to posture the tongue
forward
what can you do if the tongue continues to obstruct the airway? - ✔✔tongue traction suture; a
nasopharyngeal airway; an oral pharyngeal airway
Tongue traction suture - ✔✔When the tongue is obstructing the airway one or two sutures can be placed
through the dorsum of the tongue and grasped with a large hemostat
nasopharyngeal airway - ✔✔a flexible breathing tube inserted through the patient's nostril into the
pharynx to help maintain an open airway; can be used on awake patients; is well tolerated
