Right atrial and CVP monitoring
What is CVP Monitoring? - answerCVP (central venous pressure) is the pressure in the
large thoracic veins near the right atrium.
The CVP directly measures pressure in the superior vena cava and the right atrium
(since they openly communicate) - answerRAP is measured
CVP usually correlates with the end-diastolic (filling) pressure of the - answerright
ventricle
Since the tricuspid valve is open and there is open communication between the right
atrium and ventricle, CVP reflects - answerright ventricular heart function.
Overall, CVP reflects the relationship among - answerthe intravascular volume, venous
tone, and right ventricular heart function.
In patients with no cardiovascular disease, CVP correlates with - answerleft ventricular
end-diastolic pressure (indirect measurement).
what two readings can be seen off of the new CVP catheters? - answerScvO2 or SvO2
-This reading measures continuous central venous oxygen saturation.
-Good for monitoring for early signs of hypoxemia.
CVP monitoring can measure the right heart function directly, - answerand left heart
indirectly
normal CVP: - answer0-8 mmHg
CVP is usually inserted through the - answerjuglar or subclavian vein and it's
radiopaque catheter lies in the SVC near the right atrium.
Ideally, CVP measurements should be taken with the - answerpatient supine, without a
pillow ) with the transducer at the level of the phlebostatic axis.
If patient is orthopneic, they may be placed at a - answer30o angle or a position where
they are somewhat comfortable.
An upright position will yield a - answerlower CVP
The patient's position should be recorded, as subsequent readings should be measured
- answerin the same position.
, When measuring CVP with a pressure transducer, a continuous RAP tracing will be -
answerobserved on the monitor
Three upward deflections typically correspond to the phases of the - answercardiac
cycle
The CVP is the pressure in the large thoracic vessels of the chest and reflects the
pressure - answerpressure in the right side of the heart.
CVP is a reflection of right ventricular end-diastolic pressure or preload. -
answerAlterations in preload affect CO
Abnormal CVP may indicate - answeraltered right heart function or volume status.
CVP is most valuable when used as - answera series of readings (as opposed to one
isolated reading).
What Does an Increased CVP Indicate? - answerIntravascular volume overload
Cardiac tamponade or pericardial effusion
Right-sided valve disease
Right ventricular failure, secondary to left sided heart failure such as MI, mitral or aortic
stenosis, or cardiomyopathy
Right ventricular failure secondary to increased pulmonary vascular resistance
Right ventricular failure secondary to right ventricular infarction or cardiomyopathy
Volume overload (overaggressive IV fluids admin.)
Pulmonary hypertension
Right ventricular failure
What Does a Decreased CVP Indicate? - answerHypovolemia (dehydration or blood
loss)
Alteration in venous tone
Common Complications of CVP Monitoring - answerHemorrhage
Pneumothorax
Vascular erosions
Dysrhythmias
Infection
Fluid overload or hypothermia
Thromboembolic complications
Air embolus
PA pressure monitoring is the monitoring of - answerthe pressures within the pulmonary
artery leading to the lungs.
PA pressure monitoring provides a reflection of the - answerpulmonary blood pressure
