Effect of Environmental Temperature on Vascular Ultrasound Vein Scan Measurements

NCT06191237 | Not Yet Recruiting

• 1 other identifier: DVS009
• Study Type: observational
• Target: 30
• Locations: 0 countries
• Sites: N/A

Brief Summary

We wish to conduct two vascular ultrasound scans conducting vein measurements in two separate scanning rooms to assess if environmental temperature affects the vein diameter recorded.

Conditions

Critical Limb Ischemia

Outcome Measures

Primary Outcomes (1)

• Vein diameter measurements in two temperature controlled rooms

  Two vascular ultrasound scans will be performed on the lower limb. A defined scanning protocol will be adhered to which will ensure consistency and accuracy. During the course of both ultrasound scans, vein measurements will be taken and recorded on the study sheet which will have the participant study identification number, age and gender. The second room will be set at a higher temperature which we have defined as being 6-10 degrees greater than ambient room temperature.
