Session 1 Flashcards
surgery flow
check in
preop
surgery
pacu/icu
fire triad
ignition
fuel
oxidizer
how to extinguish fire
CO2 fire extinguisher
line isolation monitor
helps prevent electrocution in the OR
monitors input and output of devices in the OR and alarms if they are not equal
10microA leakage threshold
electrical current factors
Location
Duration
Frequency
Magnitude
fibrillation directly on myocardium
100 microA
overall max leak in OR
10 microA
radiation yearly max
5 Rem
Radiation protection
time
distance
shielding
6ft distance =
2.5mm lead
lead apron
0.25-0.5mm lead thickness
lead impregnated glass
0.5mm lead equivalency
valecula
attachment point at base of tongue and epiglottis
vocal cords
ligaments moved by muscles
airway obstruction techniques
chin lift
jaw thrust
what can cause difficulties with mask ventilation
obesity
facial hair
snoring
diabetes
rheumatoid arthritis
facial deformity
edentulous
C-collar/fixator
increased age
max mask ventilation pressure
20cmH20
Oral airway measure
from distance angle to mandible to corner of the mouth
mouth to earlobe
Nasal airway measure
nare to ear lobe
think about diameter
supraglottic airways
airway devices that can be inserted into the pharynx to allow ventilation, oxygenation, and gas administration
Laryngeal Mask Airway
(LMA)
no aspiration protection
no paralytic needed
“hands free” mask
pressure under 20cmH20
pressure for LMA
20cmH2O
why should you not overpressurize LMA
can cause air to leak into stomach
Features on some LMA
bite blocks
oral gastric ports
Esophageal-tracheal combitube
no airway protection against aspiration
2 balloons
laryngeal tube
no airway protection
not common
