Does anybody know how to code a vascular reactivity procedure?

For this they use a standard arm cuff. During the cuff occlusion the lack of blood flow elicits a microvascular dilative response (opening small vessels). Upon releasing the cuff,blood flow rushes into forearm and hand, not only restoring baseline flow but also resulting in an overshoot (reactive hyperemia). This overshoot causes shear stress in the larger arteries, which stimulates these arteries to dilate and acommodate the increased blood flow. VENDYS monitors, records, and analyzes fingertip temperature during the above cuff occlusion and release procedure. Temperature changes serve as a surrogate marker of blood flowchanges that result from vascular reactivity.

Measurement of vascular reactivity using this technology has been correlated with coronary heart disease burden.
Thank you for your opinion,
