Population Research of Sublingual Microcirculation Data of Healthy Volunteers

This study will enrolled 90 healthy volunteers. The sublingual microcirculation will be examined by sidestreamdark-field videomicroscopy (MicroScan;Microvision Medical, Amsterdam, The Netherlands). Five video sequences (20 s) was obtained from different sublingual sites, and digitally stored the images with code numbers that did not reflect volunteers' information for later offline analysis by automated analysis software (AVA 3.0; Academic Medical Centre, University of Amsterdam, Amsterdam, The Netherlands).
