| Περίληψη: | Post-ischemic flow mediated dilation (FMD), an indicator of endothelial functionality, seems to decrease after underwater diving. Until now in clinical practice, FMD is studied with an ultrasound Doppler method that measures the diameter of brachial artery before and after a five-minute forearm ischemia and subsequent hyperemia, caused by external compression with a blood pressure measurement cuff. This practice has major disadvantages like poor repeatability, extensive fluctuation in the measured values, low imaging resolution and being dependent on ultrasound operator. The aforementioned drawbacks are not present when employing an EU patented, non-invasive electrical impedance spectroscopy device (European Patent Office, 3005942 Α1, 2015), which reads bioelectrical signals of exceptional high sensitivity and accuracy using simple ECG-type electrodes placed at the forearm site of humans. Tests are performed in the NEMO 33 swimming pool (Brussels, Belgium), where volunteer divers are subjected to a well-defined dive profile at 33m depth for 20 minutes with water at 31oC. Post-dive endothelial functionality is investigated by means of electrical impedance and ultrasound measurements for 2h and they are in fair agreement. Specifically, acquired electrical impedance signals’ frequency component 0.5-10Hz seems to carry crucial information about endothelial functionality. In an effort to identify the detection limits and classify obtained results, cutting-edge algorithms are currently employed to further analyse obtained impedance signals in both time and frequency domain. |
