In this study 7 healthy volunteers were exposed to a 3 min period of vascular stasis of the right arm. The resultant reactive hyperaemia with associated skin erythemia was monitored on the forearm and finger tip of the 2nd digit with Infrared Thermography (IR) and with Laser Doppler Flowmetry (LDF).<SPAN style="mso-spacerun: yes">&nbsp; </SPAN>Following vascular stasis clear increases in skin perfusion as measured with LDF were seen at both the finger tip and forearm. However, a concomitant increase in skin temperature was only seen at the finger tip. This finding indicates that changes in skin blood flow associated with skin reactive hyperaemia and its associated erythemia may not be the same as that used for thermoregulatory purposes. It is concluded that caution should be applied when using IR thermal imaging to monitor blood flow changes associated with induced changes in skin perfusion associated with erythemia.<o:p></o:p></SPAN></P> <P style="MARGIN: 0cm 56pt 6pt 26.95pt; TEXT-ALIGN: left; tab-stops: 936.0pt; mso-line-height-alt: 10.4pt" align=left><SPAN lang=EN-GB style="COLOR: #221e1f; FONT-FAMILY: Garamond; mso-ansi-language: EN-GB; mso-bidi-font-weight: bold">KEYWORDS: Infrared Thermography, Skin blood flow, Laser Doppler Flowmetry, Vascular stasis <o:p></o:p></SPAN></P> <P style="MARGIN: 0cm 56pt 6pt 26.95pt; TEXT-ALIGN: left; tab-stops: 936.0pt; mso-line-height-alt: 10.4pt" align=left><SPAN lang=EN-GB style="COLOR: #221e1f; FONT-FAMILY: Garamond; mso-ansi-language: EN-GB; mso-bidi-font-weight: bold"><o:p>&nbsp;</o:p></SPAN></P> <P style="MARGIN: 0cm 56pt 6pt 26.95pt; TEXT-ALIGN: left; tab-stops: 936.0pt; mso-line-height-alt: 10.4pt" align=left><SPAN lang=EN-GB style="COLOR: #221e1f; FONT-FAMILY: Garamond; mso-ansi-language: EN-GB; mso-bidi-font-weight: bold">BEURTEILUNG DER HAUTDURCHBLUTUNG AM UNTERARM UND AN DEN FINGERN MITTELS INFRAROTHERMOGRAPHIE UND LASER-DOPPLER-FLUSSMESSUNG NACH KURZEM DURCHLUTUNGSSTAU<o:p></o:p></SPAN></P> <P style="MARGIN: 0cm 56pt 6pt 26.95pt; TEXT-ALIGN: left; tab-stops: 936.0pt; mso-line-height-alt: 10.4pt" align=left><SPAN lang=EN-GB style="COLOR: #221e1f; FONT-FAMILY: Garamond; mso-ansi-language: EN-GB; mso-bidi-font-weight: bold">Der Einsatz der Infrarot-Thermographie zur Diagnose von Durchlutungsstörungen beruht auf der Annahme, dass <SPAN class=GramE>die</SPAN> Veränderungen der Hauttemperatur mit Veränderungen der Hautdurchblutung vergesellschaftet sind.
