Always use an armboard for patients with an arterial line
___________
the phlebostatic axis (4th intercostal space/halfway point between anterior and posterior)
An arterial line should be leveled to
1. Stress
2. Dehydration
3. Pain
Causes of sinus tachycardia 4. Fever
5. Hypoxia
There needs to be adequate volume for there to be adequate stretch and contractility. This is
Starlings Law why with hypovolemia, contractility will eventually go down
1. Intravascular volume
2. Venous tone/pressure
3. Intra-pericardial pressure
4. Body position
Determinants of preload 5. Atrial Contraction
6. Pumping Action
Normal CVP 5
Normal wedge pressure 10
Measures of contractility CO/CI, SV/SVI, EF
Normal ejection fraction 60-65%
1. Preload/Afterload
2. Ventricular musculature
3. Neural control
4. Physiological depressants
5. Drug therapy
Determinants of contractility 6. Intrinsic depression
7. Electrolytes

Stage represents the presence of disease. Class indicates the presence of symptoms
Stage vs. Class of HF
No limitation of physical activity. Ordinary physical activity does not cause undue fatigue,
Class 1 HF patient symptoms palpitation, or dyspnea (shortness of breath)
Slight limitation of physical activity. Comfortable at rest, but ordinary physical activity
Class 2 HF patient symptoms results in fatigue, palpitation, or dyspnea.
Marked limitation of physical activity. Comfortable at rest, but less than ordinary activity
Class 3 HF patient symptoms causes fatigue, palpitation, or dyspnea.
Unable to carry out any physical activity without discomfort. Symptoms of cardiac
Class 4 HF patient symptoms insufficiency at rest. If any physical activity is undertaken, discomfort is increased.
Corticosteroids: sodium and fluid retention, blood pressure.
