Introduction

Redness of the palm during blood pressure measurement may be related to factors such as anxiety, excessive cuff inflation, or blood vessel dilation. This can be relieved by improving emotional state, reducing inflation pressure, or applying physical interventions. Besides these common causes, redness could also be associated with skin conditions like eczema, fungal infection, or Raynaud's disease. If redness on the palms persists for a prolonged period without improvement, prompt medical evaluation at a hospital is recommended.

Redness of the palm during blood pressure measurement may be related to factors such as anxiety, excessive cuff inflation, or blood vessel dilation. This can be alleviated through emotional regulation, reducing inflation pressure, or physical interventions. Specific explanations are as follows:

1. Anxiety

During blood pressure measurement, some individuals may feel nervous or anxious, leading to activation of the sympathetic nervous system, which can alter blood flow and cause localized redness of the skin. It is recommended to remain emotionally calm during measurement; listening to music or engaging in conversation may help divert attention.

2. Excessive Inflation

If the cuff is overinflated, it increases pressure on the arm, causing excessive compression of blood vessels, which may lead to symptoms such as numbness, redness, or purplish discoloration of the skin. In such cases, inform the healthcare provider promptly so they can adjust the cuff inflation level and prevent over-pressurization.

3. Vascular Dilation

When the cuff inflates, it compresses the blood vessels in the measured arm, restricting blood flow. Upon deflation, the blood vessels suddenly dilate, increasing blood flow, which may cause congestion in the palm and fingers, resulting in changes in skin color. After blood pressure measurement, gently massaging the fingers or palm can effectively improve abnormal skin discoloration.

Besides the above common causes, redness may also be associated with conditions such as eczema, fungal infection, or Raynaud's disease. If redness persists for a prolonged period after blood pressure measurement, prompt medical evaluation at a hospital is advised.
