Final Exam Flashcards
Indic. warm inspired gas
Bypassing the upper airways, Treath Hypothermiea, Patient with airways reactive to cold
Prim. goal of humidity therapy
Maintain normal physiologic conditions
Does aerosol carry pathogens easier than H20 vapor
yes
Aersol
liquid thats suspended in a delivery gas (can heat continuous aerosol)
Short term delivery of hypertonic saline via small volume neb is used to
induce sputum
Isotonic saline =
0.9% saline
cool aerosol trwats
post extubation edema, upper airway edema, croup
HFA used in propellant on
MDI
DPI
creates turbulent flow and is affected by humidity
what percent of neb reaches lower airways
10%
what percent of DPI/MID reaches lower aiways
10-20%
particle size of aerosol medication
1-5 microns
how to deliver with neb
valve t adapter
absorption ni without atelectasis
mucus/ obstructive/ increase FiO2
absolute contraindication
tension pneumothorax
IS=
sustained maximum inspiration
good start flow on EZ pap
5-7 LPM
therapeutic EZ pap pressures
10-20 cmH2O
wick humid
adds molecular H2O (vapor) to gas
important factor affecting humidifier
temp
can you add heat to a bubble bottle when delivering O2 thro NC
never
traps patients body heat
heat moisture exchange
signs of atelectasis
increase RR, increase temp, increase opacity
atelectasis breath sounds
bronchial, diminished, crackles
dep of transportation
FDA regulates construction of cylinders used to transport comp. gas in the US
oxygen in heliox
atleast 20%
supports combustion
o2 and heliox
fractional distillation
O2 med used in hospital
yellow
air
h tank psi
3.14
E tank psi
.28
standard working pressure
50 psi
tank that can lay on side
bourdon gauge
bourdon gauge
has adjustable pressure reducing valve, gravity independent, indirectly measures flow
Thorpe tube
fixed pressure, gravity dependent, directly measures flow
critical temp
absolute warmest temp at which a substance can exist as a liquid even under pressure
Daltons law
know
