In this study we used laser doppler flowmetry to investigate the parameters of peripheral blood flow in the upper extremities in young males both right- and left-handers. Based on the data obtained we found that in right-handers (dextrals) active mechanisms of regulation of blood microcirculation prevail on the leading hand, In left-handers (sinestrals) active and passive mechanisms of its regulation are involved in the regulation of blood flow on the leading hand (left) and on the opposite (right). However, the contribution of active mechanisms is lower than that of right-handers.

Novel, non-invasive wearable laser Doppler flowmetry (LDF) devices measure real-time blood circulation of the left middle fingertip and the topside of the wrist of the left hand. The LDF signals are simultaneously recorded for fingertip and wrist. The amplitude of blood flow signals and wavelet analysis of the signal are used for the analysis of blood perfusion parameters. The aim of this pilot study is to validate the accuracy of blood circulation measurements recorded by one such non-invasive wearable LDF device for healthy young non-smokers and smokers. This study reveals a higher level of blood perfusion in the non-smoker group compared to the smoker group and vice-versa for the variation of pulse frequency. This result can be useful to assess the sensitivity of the wearable LDF sensor in determining the effect of nicotine for smokers as compared to non-smokers and also the blood microcirculation in smokers with different pathologies.
