partial rebreather mask flow
6-10
-
partial rebreather mask how many one way valves
0
-
COPD pt, if you give them too much o2 you will knock out their
hypoxic drive
-
COPD Pao2 should maintain around
50-65
-
low flow devices

- partial nonrebreather
-
high flow devices
- nonrebreather
- air entrainment/ venturi mask
- briggs adapter/ tpiece
- aerosol
- trach collar
- high flow nasal can
-
non rebreather delivers fio2
21-100
-
non rebreather mask is used to deliver 100% in an emergency such as
- co poisoning
- pneumothorax
- burns
- chf
- mixed gas therapy (he/o2)
-
non rebreather ideally has __ one way valves
3
-
if the bag collapses, what should you increases
flow
-
air entrainment/ venturi mask delivers
precise fio2 concentrations
-
ideal for pts with IRREGULAR vt, rates, and breathing patterns
air entrainment/venturi mask
-
what is the precise fio2 can you give to a COPD pt
24-28% on a venturi
-
fio2 will remain the same with increases or decreases in the
flow through the o2 inlet
-
the fio2 will increase on a air entrainment only if the
- internam diameter of the gas injector increases
- with increased resistance or obstruction downstream
-
briggs adapter delivers fio2
21-100
-
reservoir tubing should be utilized on a briggs adapter to maintain the appropriate
fio2
-
what happens if the reservoir tubing is removed
fio2 will decrease due to to entrained room air
-
should you see aerosol from the reservoir tubing during inspiration?
yes
-
what should you do if aerosol disappears
- increase flow
- add more reservoir tubing
- set up a device to provide more flow-- blender, tandem set up, change flow meter
-
flow range for oxy hood
7-14
-
oxy hood can be used inside incubator to provide the infant with a more stable fio2
t/f
t
-
croup pt, and kids that are 3-6 year old can tolerate what type of o2 device
o2 tent
-
fio2 for o2 tent
40-50 and hard to control
-
if fio2 is fluctuating make sure the tent is
tightly tucked in
-
incubator administers o2 to neonate by
-
radiant warmer is ideal for
unstable newborns who require constant care
-
incubator is ideal for
stable newborns
-
diseases freq treated by HBO
- co poisoning
- decompression sickness
- tissue transplants/grafts
- anaerobic infections- gas gangrene
-
HBO therapy is conducted at pressures btwn
2-3
-
o2 is adminitered by mask or through the chamber at
100%
-
decreased the pts WOB by delivering low density gas that can easily maneuver around OBStructions.
he/o2
-
when using a o2 flowmeter to refulate the floww, actual flow delivered to the pt must be calculated
1.8 =
1.6 =
-
physiologic effects of nitric oxide are due to its ability to relax smooth muscle. decreases PVR
nitric oxide
-
indications for NO
- pulm htn
- resp dist syn
- persistent pulm htn of the newbown
-
recommend starting dose of NO is
20 ppm
-
nitric oxide is most commonly delivered via
mech vent INO
-
results in poor correlation of pox, monitor w/ coox/hemox
methemoglobinemia
-
d/c therapy when the Nitric oxisde level is at its lowest possible dose, usually around
5 ppm or less
-
if a massive leak occurs after removing a flowmeter:
- trey reinserting into the wall
- contact personall and supply supplemental o2 to pt
- turn off zone valve
-
purpose of air-o2 blender is to control the mixing of air and o2 to obtain
specific fio2
-
provides a compressed gas source w/out using an air cylinder
air compressor
-
air compressor can be used in
- hosp
- out patient clinic
- home setting
-
air compressor can be used to power a
hand held neb for a COPD pt in a home setting
-
if FIO2 is LESS than 36% use
tic toc box
21% for the tic toc box
