What is the recommended action if venous pressure increases immediately during treatment?

When venous pressure increases during treatment, it often indicates an issue such as infiltration or a blockage in the access site. Infiltration occurs when the needle has moved out of the vein, causing fluid to enter surrounding tissues rather than the bloodstream. This can lead to complications such as swelling or discomfort for the patient and requires immediate attention.

Stopping the pump and checking for infiltration is crucial because it ensures appropriate action is taken to assess the patient's safety and address the cause of the pressure increase. This action allows the healthcare provider to evaluate the access site, ensure proper venous access, and potentially reposition the needle if needed or take other corrective measures.

Taking immediate action in response to increased venous pressure helps prevent further complications and ensures that the treatment proceeds safely and effectively.
