Summary

The objective of the current study is to investigate the hemodynamic changes in the peripheral microcirculation system as a response to various changes, using noninvasive thermography and laser doppler

Detailed description

This study includes a single session per subject. Microvascular and systemic variables will be monitored in response to a number of non-invasive interventions/device that are approved for clinical use and known to elicit microvascular responses. These interventions are applied consecutively, include breathing at different rates, low power visible light in the red-to-near-infrared range, increase in local temperature, and changes in the arm position.

Conditions

• Microcirculation

Interventions

Type	Name	Description
DEVICE	Omnilux new-U (Red LED)	The left wrist (including area of radial artery) will be illuminated with the Omnilux new-U (Red LED) light source, while the right wrist will not be illuminated
DEVICE	Omnilux new-U (Near infrared LED)	The left wrist (including area of radial artery) will be illuminated with the Omnilux new-U (Near infrared LED) light source, while the right wrist will not be illuminated
DEVICE	RESPeRATE	The subjects will be guided by a digital metronome to breath at 15, 10, and 6 breaths/min for 2 minutes each using the metronome function of the device RESPeRATE (InterCure, Israel) that guides breathing using musical tones played at selectable rhythm
DEVICE	Heating bag	Applying a standard 10X13 \[cm\] heating bag on the surface of the hand at 43-45 degree Celsius for 10 seconds
