What are common signs of circulatory overload?

Circulatory overload, a situation often arising from excessive administration of fluids, can lead to several notable clinical signs. The presence of crackles and shortness of breath is particularly significant, as these symptoms indicate fluid accumulation in the lungs due to increased blood volume. This excess fluid can interfere with normal gas exchange, leading to respiratory distress. Crackles—characteristic lung sounds heard during auscultation—suggest fluid in the alveoli, while shortness of breath, or dyspnea, typically follows as the body's demand for oxygen increases.

Monitoring for these signs is crucial in IV therapy to prevent complications arising from fluid overload. Recognizing crackles and shortness of breath allows healthcare providers to take timely action, such as adjusting fluid rates or implementing diuretics, promoting patient safety and comfort.
