Abstract

Purpose: To increase patient safety, ultrasound detection acupuncture (UDA) has been developed, which can detect a safe depth for acupuncturists to avoid causing pneumothorax. This study aims to develop and evaluate a single-transducer ultrasound for acupuncture (UFA) to promote UDA. Methods: Special A-mode and M-mode signals were analyzed to identify the depth of the lung. Six subjects were recruited to test the reliability and validity of UFA on GB21, LV14 and BL43 acupuncture points. Results: The result showed UFA’s coefficient of variation was less than 0.2 and no difference in age, gender, and BMI of the subjects statistically, demonstrating excellent reliability. However, the content validity index of 0.51 did not meet expectations. UFA has good reliability, but it cannot reach the level of medical ultrasound. UFA uses A-mode and the seashore sign of M-mode to make a good identification of the lung, and it would be useful in the promotion of UDA.
