The human middle acupoint is located at the midpoint of the nasolabial sulcus in the human body and is an important emergency acupoint. Pinching or needling this acupoint can be used to treat stroke, heatstroke, poisoning, allergies, as well as coma, respiratory arrest, blood pressure drop, shock, etc. that may occur during surgical anesthesia. Why does stimulating the middle acupoint have a first aid effect? This is because rhythmic, continuous weak or strong stimulation can increase arterial blood pressure in humans, and in critical situations, hypertension can ensure blood supply to various important organs of the body and maintain vitality. Stimulating the acupoints in the human body can also affect respiratory activity. For example, continuous stimulation can cause sustained inhibition of exhalation. Proper rhythmic stimulation is beneficial for the operation of rhythmic respiratory activity.
However, the influence of acupoints on respiration is not always beneficial. If continuous stimulation causes inhalation excitation or inhibition, it can lead to respiratory activity pause. Therefore, in practical application, attention should be paid to the application of stimulation techniques. Research has shown that appropriate rhythmic stimulation is the most appropriate. In practical operation, pinch or needle the Renzhong acupoint with the tip of your thumb, pressing or twisting the needle 20-40 times per minute for 0.5-1 seconds each time.
