Hemodynamics, Shocks and Oxygenation Study Guide
1. Be sure to study hemodynamics first and get a beginning
understanding of how the heart works.
2. The Youtube video and questions will help you with terminology.
Your text will add in any gaps in learning you have. Hemodynamics is a
tool which nurses can use to care for patients. Think about scenarios in
which this tool will be beneficial.
3. 3. Review the Powerpoint on shocks and Answer the questions
provided. You also have thebrainshark recorded lecture on shock if you
want to understand better.
4. Oxygenation has been added to the packet- use as a guide to learn
the
Concepts

5. Application Time! Under each shock, identify appropriate nursing
interventions. Be sure to learn the medications. For instance,
Dobutamine — which shock is this used in? This will help you on the
next exam
6. Some students build flashcards on shocks and learn it this way.
Understanding Hemodynamics of the Heart

nursing students
Take notes. This is a short video which explains hard concepts in simple
terms. You may need to watch it more than once.
Hemodynamics:
● Regulation of blood flow
○ Heart rate
○ Strength of contraction
○ Blood vessels diameter
○ Degree of turbulence
○ Pressure
1. What does a CVP measure? How does a nurse use this information?
● Central venous pressure (right atrial pressure) measures preload
● Normal 2-6
● High = fluid excess symptoms(albumin used to treat )
● Low = fluid deficit symptoms

2. What is cardiac output and why is it important? How
is it different from Cardiac Index? Which would be
more accurate?
● Cardiac Output: the amount of blood pumped in L/min. SV x HR = CO
● Normal is 4-6 L/min
● Cardiac output is important because its the amount of blood that travels to the
organs
● Cardiac Index: it determines how precisely the CO sufficient is by factoring
body surface area (takes BP divided by weight), normal is 2.8-4.2 L/min ● Index
is more accurate
2. Define these terms.
Preload: the amount of blood to the heart (in the ventricles) at
diastole, measured by CVP, PAP (pulmonary artery occlusive
pressure) , normal 2-6
- increased in vasoconstriction
Afterload: resistance the ventricles pushes against, measured by SVR (systemic vascular
resistance, elevated is high resistance, low is little resistance), easiest is BP, PVR for left side
of heart.
Pulmonary Artery Pressure (PAP) = BP inside lungs, high=pulmonary HTN, Low = PE
Stroke Volume: the amount of blood pumped with each systolic ejection
Contractility: the force of a contraction(inotrope): beta blockers reduce contractility,
measured by CO & CI
Mean Arterial Pressure (MAP) : average pressure within the arterial system that is felt
by organs in the body, SBP + 2(DBP) / 3= MAP, normal is 65-70 or greater ● low MAP=
not enough blood flow traveling
