The lungs’ real-time states are reflected in the tissue at its related acupuncture points
This data compliments a paper entitled: The lungs’ real-time states are reflected in the tissue at its related acupuncture points. The paper fully describes and analyses the data. At the time of writing, the paper is still in production. Please see the links at the end of this dataset, which will be updated once the paper is published.

The monitored acupoints were bilateral Lung-1 (Zhongfu), right Lung-6 (Kongzui), and right Lung-9 (Taiyuan). And two control locations were also monitored, at 35/15 mm medial/caudal to left Lung-1; and 30 mm medial to right Lung-6. The acupoints were first located by an acupuncturist with 13 years experience in Chinese acupuncture, then the location of lowest impedance was verified electrically, and this was used as the test location. A thermistor was also placed under the subject’s nose to monitor the breath at his nostril. At each acupoint, a pair of custom-made electrodes were used, set at a distance of 6 mm apart, and a standard ECG electrode was attached at 4-10 cm from each acupoint, as an earth. Gel was used on each electrode. A 40 kHz 200 mv sine wave was passed through the electrodes, and the voltage monitored. A custom-made unit converted the monitored voltages to DC, then passed these to a data logger which sampled the voltages at 1 kHz. The thermistor was attached to a simple voltage divider circuit and a dc current passed through it. The voltage across the thermistor was monitored by another data logger, also sampling at 1 kHz. An Access database and macro was used to control the data loggers and convert the voltage samples into kΩ and Celsius values, before they were imported into Matlab and filtered to produce the plots. Full details of all the techniques and equipment used (including how to reliably locate acupoints electrically) can be found in the following documents. http://www.curiouspages.com/research/locate.pdf http://www.curiouspages.com/research/monitorImpedance.pdf http://www.curiouspages.com/research/monitoringTemperature3.pdf http://www.curiouspages.com/research/PicoGetSamples02.mdb The subject was a male, aged 34. In Chinese medicine terms, he suffered poor stomach and pancreas function (usually known as “Stomach chi deficiency” and “Spleen chi deficiency”); and also poor “kidney” function (known as “Kidney chi deficiency”). On the morning of the experiment, 20 July 2018, he did not eat a meal. The recording then began at 12:37 PM. During the recording, he raised a finger on his left hand to indicate the start and end of the periods when he changed his breathing. The researcher pressed a software switch to mark these moments, which produced 6 time values, marked on the plots with vertical green lines. The recording lasted for 360 s (6 mins). At 86 s, he took 4 deep breaths, lasting for 15.7 s in total. At 168 s, he breathed rapidly for 8.6 s. And at 236 s, he held his breath for 25 s.
