3 components of the Fire Triad
Oxidizer, Fuel, + Ignition
Type of shock caused by small amounts of electrical current with an external conduit that is in direct contact with the heart
Bellows are named either ascending or descending based on this phase of breathing
Expiration
In cases where airway fire is a risk, FiO2 should be reduced to this
30% or less
In order to reduce the risk of electrical shock, most power supplied to the OR is this (grounded vs. ungrounded)
Ungrounded
Two types of ventilation modes that can be used with SGA devices
PCV, PCV-VG, or PSVPro
Type of goggles that should be worn when CO2 lasers are being used
Clear goggles
Maximum current leakage allowed in the OR
10 µA
To reduce the risk of hypoxia, bellows are driven by this pressurized gas
Oxygen
Type of laser with the deepest tissue penetration
Nd:YAG
If the LIM alarms at you after plugging in a piece of equipment, this is the first step you should take
UNPLUG the last equipment cord that was plugged in
Volume Control Ventilation mode poses this risk to the pt as it ensures a set tidal volume delivered
Barotrauma
In the event that an airway fire occurs, list 4 steps that should be taken
STOP the oxygen source, lower O2 flows + disconnect the circuit, remove the ETT, pour sterile water or saline into the airway, resume ventilation, re-establish the airway, examine the airway with a FIO bronchoscope for inhalation injury
confines current + eliminates the need for a return electrode, reduces the risk of burn injury, can be used in pts w/a cardiac device
The O2 flush valve should only be used during this phase of breathing to reduce the risk of barotrauma
