through the valve the opposite way; valve becomes a two way door
What does regurgitation cause? - ✔️✔️A murmur
What is Preload? - ✔️✔️The amount of stretch on the ventricles at the end of diastole
How can preload be measured? - ✔️✔️Central Venous Pressure, Stroke volume (The
amount of blood the ventricles contracts/shoots out), Passive Leg Raise
Passive leg raise to measure preload - ✔️✔️If stroke volume increases by more than 10%
when legs are raised above the head, could benefit from more fluids
Ways to improve a low preload - ✔️✔️Fluids
Ways to improve a high preload - ✔️✔️Diuretics or dialysis in the case of kidney failure
Physical Assessment of Low Preload - ✔️✔️Hypovolemic so dry skin, dry mucus

of systole
How to measure Afterload - ✔️✔️SVR (Systemic Vascular Resistance): how
dilated/constricted blood vessels are
How to improve a low Afterload - ✔️✔️Vasopressin, dopamine (high doses),
norepinephrine, epinephrine
How to improve a high Afterload - ✔️✔️Nitroglycerin, Nicardipine, Labetelol
What is contractility? - ✔️✔️How the heart is squeezing
Ways to Measure Contractility - ✔️✔️Cardiac output, cardiac index (more individualized)
Ways to improve Contractility - ✔️✔️Epinephrine, dopamine and dobutamine, digoxin
What are example of invasive lines? - ✔️✔️Peripheral lines, Arterial lines, Central Venous

What if a transducer is too low? - ✔️✔️Artificially too high of a BP
What if a transducer is too high? - ✔️✔️Artificially too low of a BP
How to care for a Peripheral Line? - ✔️✔️Check for infiltration, redness and swelling at
the sight, Check for infection
How to care for a Central Venous Catheter? - ✔️✔️Inserting sterile and keeping a sterile
dressing over it, Clean off ports before you give medication, Green caps that are full of
alcohol to keep the ports clean when they aren't being used, Flush every 8 hours, CHG
bath, bath every day in general
How to care for a Pulmonary Arterial Line? - ✔️✔️Similar to Central Lines
Normal Sinus - ✔️✔️PR interval 0.20, QRS interval less than .11, Rate is 60-100

60
