Fundamentals part 2 Flashcards
VS info typically shown on the space lab/monitor
Heart rate
ART
CVP
Pulse ox
What is an ART or arterial blood pressure
Standard reading times?
Coding?
Invasive BP with a line.
q15min
if coding, q3m
What is an NIBP reading
Noninvasive BP
- done with a BP cuff
You get an NIBP or cuff pressure on your hypertensive pt. The BP is oddly low compared to the trends. what do you check
Check to see if the cuff was too large
so if its large its false low
if its small, itll be a false high
You have a patient on q15min NIBP cuff checks and they are stable as can be. what should you do
max bp reading schedule
what is the final thing to remember when doing NIBP
Assess to see if they even need to have their cuff read that much due to skin damage and comfort reasons
1 hr max
check titrating drips
Which method is more accurate ART Or NIBP for bp readings
ART due to invasiveness
Four ART sites
most common?
assessments?
radial - common
femoral
pedal
brachial
for any of these make sure you are assessing for signs of a clot
- call doc for blood thinner if need be
What does the saline pressure bag provide for an ART blood pressure line
good indicator?
pressure value?
do u need to worry about fluid overload?
Provides pressure to prevent clot or occlussion of the line.. also keeps blood in patient
green
300 mmh
, 3 ml/hr
- so don’t have to worry about fluid overload
pros of art blood pressure
direct and continuous
can do blood draws
what does the transducer do for the art blood pressure
provides electrical read out
what is a three way stopcock for on ART
need to pull it to get blood, put 10 ml of waste in syringe, get your good blood, then flush blood back to patient
What is MAP?
range?
mean arterial pressure
- often better indication of status
60-100
what should you do before every shift concerning ART?
what can you look at the see accuracy?
zero it out
waveform
- aortic closure on wave
What is CVP?
what does it reflect? and what does this mean for you
central venous pressure (a type of line)
fluid volume status
- if their cvp is in deficit it means they are dry…so we don’t wanna infuse meds
Which line can you infuse meds through?
CVP only
normal CVP range
what if it is 0-1?
what if it is 8+/higher?
What can cause the cvp to drop?
0-8 mmhg is the range
o-1 = hypovolemia
Above 8 means/higher means hypervolemia/rt sided HF
Sooo in short, we use cvp to assess right side of heart and volume status of fluids
CVP can alter due to patient positioning
Normal range for ICP
what does ICP monitor
0-15 mmHG
Cerebral spinal fluid + brain pressure
If a patient has a ICP drain in , what do you need to do before repositioning them?
What position should you keep them in?
Clamp the drain before moving them bc fluid will shift
Midline position for pt is best
Where are drains placed for ICP?
Ideal icp for a patient already having ICP issues?
Lateral ventricles via intraventricular catheter
20-25 mmhg. Anything above that and we have an emergency
