A client with heart failure may have a normal looking blood pressure while fluid is accumulating, or may become acutely breathless before peripheral edema changes.
A client with heart failure may have a normal-looking blood pressure while fluid is accumulating, or may become acutely breathless before peripheral edema changes. The RPN's first clinical question is not simply how much edema is present; it is whether congestion is now impairing oxygenation or reduced cardiac output is impairing perfusion. The ventricle's difficulty filling or ejecting creates two linked problems: pressure rises behind the failing pump, and forward blood flow falls. That relationship explains why crackles and orthopnea can become an emergency, why urine output and mental status reveal perfusion, and why a weight trend may identify deterioration before the client looks dramatically swollen.
