Term
|
Definition
|
|
Term

BNP 100-400 NT proBNP 400-2000 |
|
|
Term
|
Definition
|
|
Term
arterial line: continuous arterial BP monitoring, frequent ABG draws central venous catheter: delivers fluid and drugs into central circulation, measures central venous pressure (CVP), measures venous oxygen saturation pulmonary artery catheter (Swan-Ganz): measures and calculates hemodynamic parameters, such as left ventricular pressure, fallen out of favor due to high complication rates |
|
Definition
invasive monitoring: arterial line central venous catheter pulmonary artery catheter (Swan-Ganz) |
|
|
Term
|
Definition
pulmonary capillary wedge pressure (PCWP) estimates ( ) |
|
|
Term
|
Definition
cardiac index is CO divided by BSA. it is standardized so comparisons can be made. Tells you if a patient is ( ) |
|
|
Term
|
Definition
systemic vascular resistance estimates ( ) |
|
|
Term
|
Definition
mean arterial pressure (MAP) evaluates ( ) |
|
|
Term
|
Definition
at what point does a PCWP reading indicate AHF? |
|
|
Term
|
Definition
at what point does a cardiac index reading indicate HF? |
|
|
Term
refractory HF symptoms refractory hypotension (SBP < 80) worsening renal function during therapy concurrent cardiac and pulmonary disease hypoxia in need of intubation |
|
Definition
patients with these conditions will be considered for invasive monitoring |
|
|
Term
|
Definition
therapy used if the patient is fluid overloaded [image] first line treatment of symptoms due to mild to moderate fluid retention if once daily dosing at home, double the dose and give as IV bolus OR if on multiple doses at home, total daily dose given as IV bolus if no adequate diuresis, double the subsequent doses until achieved try to maintain a net loss of 1L |
|
|
Term
|
Definition
lack of or inadequate increase in urine output despite increasing diuretic dose decreased intravascular volume -> increased RAAS and SNS decreased renal perfusion due to low CO Na overload |
|
|
Term
Na and water restriction (2g of Na and 2L of water) increase diuretic dosing frequency or give as continuous infusion combine with another diuretic may consider cautious fluid replacement if intravascularly dry may consider adding inotrope if hypoperfusion is suspected |
|
Definition
how to overcome diuretic resistance |
|
|
Term
vasodilators venous vasodilators: nitroglycerin, nitroprusside, nesiritide arterial vasodilators: nitroprusside, nesiritide |
|
Definition
should be considered in patients with persistent symptoms despite aggressive loop diuretics and have SBP > 110-120 mmHg (avoid in SBP < 90) |
|
|
Term
nitroglycerin: tolerance nitroprusside: cyanide or thiocyanate accumulation nesiritide: increased risk of worsening renal function, increased risk of death |
|
Definition
adverse effects of vasodilators |
|
|
Term
|
Definition
therapy used if the patient is intravascularly dry [image] however, further increase in preload in a failing heart may exacerbate the condition if unsure of preload and the patient has signs of hypoperfusion (cardiogenic shock) this may be attempted if no improvement in BP, inotrope should be considered |
|
|
Term
dobutamine dopamine milrinone |
|
Definition
( ) is the inotrope of choice. concurrent use of BB should be DC'd ( ) is indicated in SBP <90 or symptothetic hypotension, despite dobutamine ( ) is indicated for low CO, but SBP is > 90 and on concurrent BB. |
|
|
Term
|
Definition
therapy reserved for sicker patients signs of hypoperfusion despite vasodilators and/or diuretics unresponsive/intolerant to vasodilator (add to or replace vasodilators) severe LV systolic dysfunction (low EF) cardiogenic shock may allow continued diuretic +/- vasodilator therapy lowest possible dose for the shortest possible duration continuous monitoring of BP and EKG used most in subset 4 patients (wet and cold) |
|
|
Term
vasopressors adrenergic agonists EPI and NE |
|
Definition
only use in cardiogenic shock with severe hypotension (SBP < 70) may exacerbate high SVR and further decrease organ perfusion |
|
|
Term
for fluid overload patient with inadequate response to diuretic therapy |
|
Definition
ultrafiltration filters the blood in order to remove excess Na and water. It pulls off more fluid than IV diuretics without effecting BP, HR, or electrolytes. when is it used? |
