NR 341 Exam 2 Hemodynamics ABGs
|\ |\ |\ |\ |\ |\
questions with answers |\ |\
What does CVP stand for
|\ |\ |\ |\
- Central Venous Pressure
|\ |\ |\
What does Preload mean?
|\ |\ |\
- The VOLUME of BLOOD going INTO the HEART during Diastole
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
(AKA the Volume of blood in ventricles***)
|\ |\ |\ |\ |\ |\
What is the normal range of Preload?
|\ |\ |\ |\ |\ |\
- 2-6 L
|\ |\
What level normally is responsible for measuring Preload?
|\ |\ |\ |\ |\ |\ |\
- CVP is normally responsible
|\ |\ |\ |\
What does a CVP level of < 2 indicate is occurring?
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
- Fluid Volume Deficit
|\ |\ |\
,What does a CVP level of > 6 indicate?
|\ |\ |\ |\ |\ |\ |\ |\
- Fluid Volume Excess
|\ |\ |\
What medication can be utilized to treat High (>6) CVP (or
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
Preload)?
- Albumin can be utilized to treat high preload
|\ |\ |\ |\ |\ |\ |\ |\
What level increases when CVP increases?
|\ |\ |\ |\ |\
- The PAOP will also increase
|\ |\ |\ |\ |\
If a patient has a CVP (Preload) < 2, what type of fluids would we
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
utilize to increase fluid volume in the patient?
|\ |\ |\ |\ |\ |\ |\ |\
- Isotonic Fluids
|\ |\
What are some Isotonic fluids that can increase CVP (preload) in
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
a patient?|\
- 0.9% Normal Saline
|\ |\ |\
- Lactated Ringers (LRs)
|\ |\ |\
What is the definition of Cardiac Output (CO)?
|\ |\ |\ |\ |\ |\ |\
,The amount of blood pumped out to the body (L/min)
|\ |\ |\ |\ |\ |\ |\ |\ |\
What is the equation for Cardiac Output (CO)?
|\ |\ |\ |\ |\ |\ |\
CO = Stroke Volume (SV) x Heart Rate (HR)
|\ |\ |\ |\ |\ |\ |\ |\
Why is cardiac output (CO) very important?
|\ |\ |\ |\ |\ |\
- b/c it is responsible for delivering everything (Oxygen, nutrients,
|\ |\ |\ |\ |\ |\ |\ |\ |\
etc), the organs/ tissues need to survive
|\ |\ |\ |\ |\ |\ |\
What is the definition of Cardiac Index (CI)?
|\ |\ |\ |\ |\ |\ |\
- Utilized To determine how precise the CO sufficiently is within
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
the individual patients body
|\ |\ |\
What is the equation for Cardiac Index (CI)?
|\ |\ |\ |\ |\ |\ |\
- Cardiac Output (CO)/ Total Body Surface Area
|\ |\ |\ |\ |\ |\ |\
What is the normal Cardiac Index (CI) levels?
|\ |\ |\ |\ |\ |\ |\
- 2.8-4.2 L
|\ |\
, Which is more accurate: Cardiac output (CO) or Cardiac Index
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
(CI)?
- Cardiac Index is more accurate b/c it is individualized to the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
person
If the Stroke volume of the patient is low, what increases?
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
- The patient will have an increase in Heart Rate (HR) to
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
accommodate the decrease in Stroke Volume (SV) |\ |\ |\ |\ |\ |\
What is the Stroke volume consist of?
|\ |\ |\ |\ |\ |\
- Preload
|\
- Afterload
|\
- Contractility
|\
- Cardiac output
|\ |\
What do you need in order to measure Preload (CVP)?
|\ |\ |\ |\ |\ |\ |\ |\ |\
- Central line
|\ |\
- Swans Ganz
|\ |\
What does a Central line give you, when assessing Preload(CVP)?
|\ |\ |\ |\ |\ |\ |\ |\ |\
- The Pressure of the Right Ventricle
|\ |\ |\ |\ |\ |\
