DAANCE Module IV & V-emergency protocolSedation
Flow meters- what are these used to monitor? - Correct Answer determines the ratio of
the O2/N2O mixture as well as the rate at which it is delivered.
Anesthesia Machines
What are the two types of anesthesia?
Where are each type of anesthesia used?
What are the two machines used with the first type of anesthesia?
What are two safety features of the second type of anesthesia? - Correct Answer -
Inhalation and N2O2/O2 Anesthesia
- Inhalation at the hospital, N2O2/O2 in office
- vaporizers and ventilators
- Regulator-fail safe Mechanism and Scavenging System
Vaporizer
What does this device do?
What kind of maintenance does this device have? - Correct Answer A device that
converts liquid anesthetic to gases suitable for delivery with other gases.
Maintenance and Checks: periodic maintenance and frequent calibrated
Ventilator
What does this device do?
Why is this device so useful?
What type of anesthesia is this used with?
What kind of maintenance does this device have? - Correct Answer -A machine that
breathes for the pt using a bellows type apparatus with +/- pressure to move gases in
and out of the lungs.
-Eliminates the need to manually squeeze the reservoir bag.
-Used with a closed system (i.e. Endotracheal Intubation)
-The anesthetic system should have a high/low pressure alarm to indicate excessive
pressure or a disconnect has occurred.
Regulator-Fail Safe Mechanism
What setting are these used?
What level of O2 will these mechanisms be engaged at?
What kind of maintenance does this mechanism require (5 things)? - Correct Answer -
Office based anesthesia.
-Most anesthesia machines will stop delivering automatically when the O2 level is
unsafe (20%).
Maintenance and Checks:
-Flow meters, reservoir bags and delivery tubes checked daily or patentcy and leaks.
-Calibrate to manufacturer specs
-A record should be kept during surgery.
, -Turn off O2 daily
-Have back up O2 available (Sep. O2 tanks)
Scavenging System
What does this system do?
Why do we use this system? - Correct Answer -It reduces the level of noxious agents to
an acceptable level by exhausting them outside the room.
-Excess gases and vapors may be expelled in the operatory from leaks in the System or
through pressure relief/pop off valves.
Anesthetic Gases (color coded cylinders)
Why do we color code gas tanks?
Match the color to the gas (green, blue, gray, yellow, black, brown)
Which gases are associated with 2000psi and 750psi?
What maintenance is required for tanks? - Correct Answer - to minimize potential for
incorrect connection to anesthesia systems.
Oxygen- Green (2000psi)
Nitrous Oxide- Blue (750 psi)
Carbon Dioxide- Gray
Compressed Air- Yellow
Nitrogen- Black
Helium- Brown
-shut off after last pt.
Airway Adjuncts
-What is the first thing used in the case of airway obstruction?
-What is the second step is obstruction continues? How is this placed?
-What is the first type of airway placed if the initial 2 steps do not work? How is it placed,
and is the patient awake or asleep?
- What is the second type of airway placed? How is this placed and what is the benefit
of this? Are patients awake or asleep? - Correct Answer 1. Bag/Valve/Mask/Full
Facemask
2. Tongue Traction Suture- 1 or 2 sutures can be placed through the dorsum of the
tongue and grasped with a lg. hemostat.
3.Nasopharyngeal Airway- lubricated tube passed through the nares into the nasal
cavity through the oropharynx to posterior of the tongue. Easily inserted and tolerated in
awake patients.
4. Oropharyngeal Airway- not tolerated well by pts. It may be placed to position the
tongue more anterior.
Supraglottic Airways (2 types)
