ICU Flashcards
decreased mm mass and protein synthesis. Insulin resistance w/in 5 days.
ICU Aquired Weakness ICUAW
early intervention and increased activity in ICU leads to…(2)
- decreased stay
2. better outcomes
with disuse, bone density changes occur after…
3-6 weeks
mm atrophy occurs in which mm first?
biggest and strongest
TF bone density and mm changes are likely to occur in the ICU
False. Usually short stay
primary cause for ICU care
hypoxia
inflated particle bed, reduces pressure on skin to reduce ulcer formation
clinitron
tachycardia =
bradycardia =
> 140 bpm
<60 bpm
Normal ejection fraction EF
60-65%
Hypotension BP
Hypertension BP
<60 mmHg
>200 mmHg
ventilator that does all the work
CMV constant mechanical ventilation
pt can take some breaths on their own, ventilator fills in to reach set rate/depth of breath
SiMV
ventilator suspended but not removed to see how pt does on their own
SBT spontaneous breathing trial
breathe out against a force. Balloon inflates before fully deflating
PEEP positive end expiratory pressure
constant amount of pressure throughout respiratory cycle. makes alveoli stay open longer. sleep apnea
CPAP constant positive airway pressure
normal room FiO2
can be increased up to
21%
60%
FiO2 increases _____ for every 1L of O2
4%
trache tubes, endotrache tubes. Not own breaths
invasive ventilator supported
CPAP (1 pressure), BiPAP (2 pressure)
Non invasive ventilator supported
Nasal cannula, venturi mask, non-rebreather mask. Pt’s own breaths
non invasive non ventilator supported
% of hemoglobin with O2 / total hemoglobin
sO2
% of O2 in space being measured
FiO2
sedation meds
Propofol vs Ativan/Fentinyl
fast acting vs slow acting
decreased drugs to see if pt can respond and breathe on their own
sedation holiday
4 types of ICU lines
- peripheral
- indwelling
- monitoring
- drains
example of peripheral lines
IV
example of indwelling lines
central line
example of monitoring lines
vitals
example of drains
chest tube, catheter
drain line placed at bottom of wounds
J-P (Jackson-Pratt)
In/Out line. Skinny tube for feeding
Dobhoff
In/Out line. Drains the gut
G-tube
In/Out line. Directly into stomach for feeding
PEG
In/Out line. Directly into jejunum for feeding
J-tube
gives you a head start on how tx session will go. Observe status, lines, cultural background
doorway assessment
TF you should talk to pt and introduce yourself even if they are unresponsive
true
number 1 goal for pts in the ICU
Get out of ICU. Functional activity is best
TF you may do ROM exercises w/ neurologically involved pts, if that is all that can be done
true
FiO2 over 60% increases….
CO2
when performing a ventilator walks, coordinate w/…
respiratory therapist, other team members
must be turned off/clamped before changing positions
lumbar and v-drains
if FiO2 is greater than _____, you should think before getting pt up
50%
if sO2 is below 88%…
below 85%
give supplemental O2
don’t tx (hypoxic)
do not tx is hemoglobin levels are…
Light ex…
Resistive ex…
< 8g/dL
8-10 g/dL
>10 g/dL
