|
normal PCWP |
6-12 mmHg |
|
|
PCWP |
Pulmonary capillary wedge pressure the momentary balloon inflation of a pulmonary artery catheter, it is reflective of left ventricular end-diastolic pressure. |
|
|
what is cardiogenic shock |
it is the failure of the heart to pump adequately thereby reducing cardiac output and compromising tissue perfusion. to necrosis is more than 40% of the left ventricle usually as a result of occlusion of major CORONARY vessels |
|
|
what is central venous pressure? |
it is the pressure within the superior vena cava that reflects the pressure under which blood is returned to the superior vena cava and right atrium the normal severe pressure is about 3 to 8 mmHg elevated means an increase in blood volume, as a result of sodium and water retention excessive fluid iv and alteration in fluid balance or renal failure decrease indicates a decrease in circulating blood volume, and may be a result of fluid imbalances hemorrhage or severe vasodilation with pulling of blood in the extremities that limits venous return. |
|
|
cardiac tamponade |
an accumulation of fluid in the pericardial cavity, happens when the space between variable and visceral layers of the pericardium fills with fluid
it can occur when small volumes 20 to 50 ml (150 ml) of fluid accumulate rapidly in the pericardium |
|
|
cardiac output formula |
Stroke volume (preload, afterload, contractility, [SVR and HR] ) x Heart rate |
|
|
Unna boot |
a compression dressing made by wrapping layers of gauze around your leg and foot |
|
|
embolectomy |
removal of an embolus from an artery using catheter |
|
|
Normal PR and QRS |
PR = 0.12 - 0.20 QRS = 0.04 - 0.10 |
|
|
what is morphine surfate |
binding to opioid receptors blocks transmission of nociceptive signals, signals pain-modulating neurons in the spinal cord, and inhibits primary afferent nociceptors to the dorsal horn sensory projection cells Antidote: Naloxone |
|
|
Digoxin normal therapeutic serum level |
0.5-2 ng/mL |
|
|
4 interventions for ventricular fibrillation |
1. Defibrillate (200,300,360 J) 2. Initiate CPR 3. Administer oxygen as prescribed 4. Administer antidysrhythmic therapy as prescribed |
