Body weight changes point to a need for monitoring fluid volume status in HF.
Sudden weight gain > 5 pounds or significant weight loss, determined at the same time each day, can be HF “warning signs.”
An increased respiratory rate (> 16 breaths/min) accompanied by dyspnea may indicate the onset of acute HF decompensation.
Pulse and blood pressure abnormalities can be signs of worsening HF.
