Hemodynamic Monitoring Flashcards
accuracy in hemodynamic monitoring depends on these things
**positioning at the phlebostatic axis (4th intercostal space, midaxillary line*nipple line)
**zeroing reference (negate atmospheric pressure, “0” stopcock)
dynamic response testing
3 types of hemodynamic monitoring
A-lines
cvp/rap - central venous catheters (RAP/CVP)
pa catheters - pulmonary artery
primary goal of hemodynamic monitoring
assess and trend tissue perfusion adequacy
2 ways to assess tissue perfusion
noninvasive and invasive
noninvasive measures for tissue perfusion
BP, JVD
invasive measures for tissue perfusion
right atrial pressure (aka CVP)
pulmonary artery pressure
arterial pressure
tell me about lactate levels (non-invasive monitoring)
end product of cellular metabolism under anaerobic conditions
trend values
venous or arterial
***indications for invasive monitoring
decreased cardiac output
ineffective tissue perfusion
fluid volume excess or deficit
indications for noninvasive monitoring
low BP - hypotensive
flat JVD
decreased urine output
complications of invasive monitoring
infection
thrombosis
what can alter lactate levels
liver dysfunction
what 5 pcs compromise invasive monitoring systems

The nurse returns from the cardiac catheterization laboratory with a patient following insertion of a pulmonary artery catheter and assists in transferring the patient from the stretcher to the bed. Prior to obtaining a cardiac output, which action is most important for the nurse to complete?
Zero reference the transducer system at the phlebostatic axis.
why do we use a-lines or arterial lines
measure arterial BP - its more accurate (sepsis)
frequent ABG’s (easy access)
most frequent insertion site for Aline
radial artery
