RAP/CVP Monitoring Flashcards
Why is RAP monitoring used?
to assess a patient’s CENTRAL VENOUS PRESSURE or FLUID VOLUME status
How to measure RAP
either a central venous catheter
or
the proximal port of a pulmonary artery catheter
(also used for CVP)
If using a central venous catheter, the line is placed WHERE by a physician most often?
superior or inferior vena cava
Central venous catheters infuse fluids via
single, double, or multiple (triple) lumens
Right atrial pressures are used to assess?
preload of the right heart,
the value of which reflects the fluid volume status of the patient
RAP/CVP Measured values are used to guide?
- ) fluid replacement and
2. ) assess the status of the right ventricle.
Normal central venous pressures range between
2 and 6 mm Hg
During breathing, Right atrial pressure is measured when?
on end exhalation
to ensure that pulmonary changes do not skew the numeric value
RAP/CVP provide a direct measurement of what?
pressures in the right atrium
Nursing Implications
Best Patient position for accurate BP ?
Head of bed between 0 and 60 degrees = accurate BP
Nursing Implications
BP drops when the pt changes what position
sitting up
Correlate values with assessment:
High CVP means
- ) right sided failure,
- ) pulmonary hypertension,
- ) hypervolemia,
- ) Vents,
- ) vasconstriction
Correlate values with assessment:
Low CVP means
- ) hypovolemia,
- ) vasodilation,
- ) patient position
Possible Complications of RAP/CVP Catheter Insertion
- ) Infection
- ) Pneumothorax or hemothorax
- ) Carotid puncture
- ) Heart perforation
- ) Dysrhythmias
Can the nurse: RAP/CVP Catheter Insertion?
NO
Where is the RAP/CVP catheter inserted?
Inserted at subclavian
- a pair of large arteries in the thorax that supply blood to the thorax itself, head, neck, shoulder and arms
How do you assess for Pneumothorax?
What are the expected findings?
Assess: lung sounds
- absent lung sounds (pneumo),
- diminished breath sounds
Pneumothorax Assessment
What do you do if no breath sounds are heard?
call the HCP,
Expect
- x-ray order
- Chest tube placement
Pneumothorax Assessment
Nursing interventions as you wait for x-ray/chest tubes?
- give O2,
- raise HOB 30-40 degress
(think of resp distress interventions = comfort and safety)
Carotid puncture Assessment
What would this complication look like?
hematoma development/formation
Carotid Puncture
Nurse Interventions
- apply pressure
- monitor site
- feel around the proximal area to make sure there is no hematoma build-up
- Then call for help
(* build-up would mean an arterial leak)
Then call for help
Heart perforation Assessment
Expected finding?
- dysrhythmias
- arrhythmias
- chest pain
- pressure dropping
