Marfan syndrome
|
|
|
the inability to maintain cardiac output sufficient to meet the metabolic demands of the body. occurs most frequently secondary to congenital heart defects in which there is structural abnormalities. This results in increased volume or increased pressure on the ventricles
|
pediatric CHF
|
|
|
S/S- tachycardia (>160), tachypnea (>60), grunting, nasal flaring, rales, wheezes or cough
facial/eye edema, neck vein distention, enlarge liver and spleen, and decreased peripheral perfusion and output Mottling, cyanosis, pallor Lethargic, irritable or fatigued Wt gain-earliest sign of edema (sacral and scrotal) neck vein distention |
CHF
|
|
|
4 Goals of treatment of CHF
|
1. Improve cardiac function
2. Remove accumulated fluid 3. decrease cardiac demands 4. Improve tissue oxygenation and decrease oxygen consumption |

|
if pulse is below 90 and 110 bpm in newborns
below 70 in children below 60 in adults |
