The present project plans to detect pregnant pulses using this portable ANS (autonomic nervous system) Watch connected to a laptop. One hundred pregnant women and 100 non-pregnant women will be recruited.
ANS(autonomic nervous system) Watch has been developed as to detect pulse waves using a pressure detector. It is used to measured cardiovascular indices, including cardiac output, and vessel stiffness. ANSWatch is developed to apply to the prediction of traditional Chinese medicine (TCM) pulses, such as the wiry pulse. There are 28 types of pulses in TCM. Among them, the slippery pulse is the most commonly seen pulse in pregnant women. The present project plans to detect pregnant pulses using this portable ANSWatch connected to a laptop. One hundred pregnant women and 100 non-pregnant women will be recruited. After taking the indices of the subjects, a neural network is designed to provide the prediction for pregnancy constitution, pregnancy pulse and slippery pulse in pregnant women.

The indices of pulse waves measured by ANSWatch , a pulse wave machine(https://www.taiwanscientific.com.tw/%E5%BF%83%E5%BE%8B%E5%A4%A7%E5%B8%ABanswatch). A neural network is designed to provide the prediction for pregnancy pulse.
Time frame: Day 1
Constitution
Nine constitutions will be measured using the "Nine constitution Questionnaire" (in Chinese). This questionnaire defines whether subjects have Yin-deficiency, Yang-deficiency, Qi-deficiency, Phlegm-dampness, Dampness-heat, Special dialesis, Blood-stasis, Qi-depression, and Neuter constitutions. The questionnaire is divided into several sections, each addressing different aspects of the subject's constitution. Within each section, there are 6 to 8 sub-questions, and responses are rated on a scale from 1 to 5, reflecting the intensity or frequency of the subject's experiences.Sum the scores from all sub-questions within the section to obtain the raw score,which is then transformed to a 0-100 scale. If the transformed score falls below 30, it suggests that the subject does not exhibit characteristics of this constitution.Scores between 30 and 40 indicate a tendency towards this constitution.Scores exceeding 40 indicate that the subject belongs to this constitution.
