Background
What is measured?
- Flow Mediated Skin Fluorescence (FMSF) is a technique based on the measurement of NADH fluorescence from skin tissue cells.
- Nicotinamide adenine dinucleotide (NADH) and its oxidized form (NAD+) play a crucial role in biological systems as redox coenzymes.
- The NADH/NAD+ pair is the carrier of electrons in the respiratory chain of each living cell.
- Although NADH emits significant fluorescence, this is not the case with NAD+.



- The fluorescence from NADH is the strongest component of the overall fluorescence emitted from human skin.
- The penetration depth of excitation light for NADH (340 nm) in skin tissue is low (about 0.5 mm), therefore a substantial fraction is absorbed by the epidermis and papillary dermis.
- In these skin regions, the density of blood microvessels is low and the changes in NADH fluorescence depend on the supply of oxygen diffused from deeper layers.
How is it measured?
- The FMSF technique measures changes in the intensity of NADH fluorescence from the skin on the forearm as a function of time, in response to blocking and releasing blood flow in the forearm.
- Blood flow in the forearm is blocked using a typical occlusion cuff, as used to measure blood pressure.
Advantages of FMSF method
- useful for assessing circulatory status by comparing the vascular response to reactive hyperemia (PORH) to the resting state (before occlusion),
- suitable for assessing the degree of ischemia and reperfusion in skin cells depending on blood flow in the vessels,
- useful for assessing the progress and remission of microcirculation disorders, metabolic regulation and vascular complications,
- optimal for the observation of microcirculation oscillations, the amplitude and frequency of which may signal irregularities in the microcirculation,
- helpful for monitoring vascular circulation disorders and selecting individualized forms of therapy.
The FMSF method has intellectual property protection, including in the following countries: EU, USA, Canada, China, Japan, Australia, Russia.
Main parts of a typical trace recorded for an individual patient using AngioExpert
- Baseline – collected for 3 min (or 4 min if unstable).
- Ischemic response (IR) – 3 min occlusion with cuff inflated to 60 mmHg above systolic blood pressure, resulting in an increase of NADH fluorescence.
- Hyperemic response (HR) caused by releasing pressure in the occlusion cuff – NADH fluorescence decreases below the baseline, reaching a minimum followed by a return to the baseline.
- Hyperemic response (HR) with two distinct phases:
1) hyperemia – related to a sharp drop in NADH fluorescence for 20–30 s;
2) reperfusion – a much slower return to the baseline.
Definition of measured parameters
Hyperemic response parameters HRmax and HRindex express changes in NADH fluorescence (mainly from the keratinocytes in the epidermis) and determine the metabolic reaction of the skin cells to hyperemia and reperfusion.
Ischemic response parameters IRmax and IRindex express changes in NADH fluorescence (mainly from keratinocytes in the epidermis) and determine the sensitivity of skin cells to hypoxia caused by blocking blood flow in the forearm. This sensitivity is determined primarily by the efficiency of oxygen transport to the epidermal cells just before occlusion.


Interpretation of the measured parameters
- HRmax refers to the efficacy of oxygen supply to the epidermis during hyperemia via skin microcirculation and can be treated as an indirect measure of NO bioavailability in the microcirculation.
- HRindex refers to the recovery of metabolic status in the epidermis following hyperemia caused by the release of pressure in the occlusion cuff.
- HRmax and HRindex are key parameters demonstrating the diagnostic power of the FMSF technique.
- Parameters IRmax and IRindex are sensitive to deviations from the measurement procedure and carry auxiliary diagnostic significance.
- Microvascular oscillations on the baseline and the hyperemic response line express the efficacy of vascular-metabolic regulation related to microvascular dermal flow. A weakening of their amplitude and changes in frequency may indicate the presence of microvascular dysfunction.
Threshold values of the key parameters for diabetes
Based on the results of tests and experiments, threshold values have been established indicating serious disorders in microvascular and metabolic regulation and signaling the risk of vascular complications in diabetes patients.
The HRindex parameter has particularly high diagnostic sensitivity and specificity for assessing the risk of developing vascular complications:
HRindex > 13% | low risk |
8% < HRindex < 13% | moderate risk |
HRindex < 8% | high risk |
Advantages of the FMSF technique
- enables early diagnosis of dysfunctional vascular circulation,
- identifies diabetic patients at risk of vascular complications at an early stage,
- assesses the risk of metabolic disorders in patients with type 1 diabetes,
- assesses the risk of serious cardiovascular complications in patients with type 2 diabetes,
- is recommended for monitoring patients with diabetes over time to enable early identification of dysfunction and disturbances in vascular circulation and metabolic regulation.
Oscillations in the microcirculation, known as flowmotion, are a well-recognized characteristic of cutaneous blood flow. Since flowmotion reflects the microcirculatory status of the vascular system, which is frequently impaired in many diseases and disorders, a quantitative assessment of skin flowmotion could be used to screen for early symptoms of such conditions. Skin flowmotion can be monitored closely and precisely using the FMSF technique, as there is very low noise in the recorded FMSF traces.
Since NADH fluorescence is sensitive to the supply of oxygen to the epidermis via skin microcirculation, use of the FMSF technique to monitor flowmotion appears to be a unique tool for the characterization of microcirculatory status.
Flowmotion parameters
Two different periods of oscillations can be distinguished in the FMSF signal:- basal oscillations at rest,
- flowmotion during the reperfusion stage.
Microcirculatory oscillations in the recorded FMSF signal are analyzed in three major frequency intervals, namely ≤ 0.021 Hz, 0.021 – 0.052 Hz, and 0.052 – 0.15 Hz, which correspond to endothelial (endo), neurogenic (neuro), and myogenic (myo) activity, respectively.
In addition, the strength of the oscillations, the so-called Power Spectral Density (PSD) is determined. PSD is strongly correlated with the FM and FM(R) values. FM and FM(R) represent the mean deviations of the fluorescence signal (amplified 106 times) from the polynomial function fitted to the oscillatory curve at baseline and reperfusion, respectively. FM and FM(R) remain unitless values because the fluorescence changes were normalized in the algorithm used in the program.
In summary, the following quantitative measures of oscillations have been defined:
- FM – a parameter characterizing basal flowmotion at rest,
- FM(R) – a parameter representing flowmotion during the reperfusion phase, which reflects the strong effect of hypoxia on flowmotion, mainly due to the increased activity of the vessels. This parameter enables the assessment of vascular wall stiffness,
- HS(Hypoxia Sensitivity) - a direct measure of the intensity of flowmotion related to myogenic oscillations (0.052 – 0.15 Hz) recorded during reperfusion.
Hypoxia Sensitivity parameter (HS)
Myogenic oscillations are stimulated on the reperfusion line after transient ischemia, which is achieved by restricting blood flow in the brachial artery using an occlusion cuff. Since the HS (Hypoxia Sensitivity) parameter measures the intensity of flowmotion, it is well-suited for quantitative characterization of the microcirculatory response to hypoxia. The HS parameter describing the microcirculatory response to hypoxia has been found to depend on age, gender, hypertension, diabetes, and CVD.Four ranges of HS values describing distinguishable levels of microvascular function (very low, low, moderate and high) are determined:
high | HS ⩾ 100 |
moderate | 30 ≤ HS < 100 |
low | 10 ≤ HS < 30 |
very low | HS < 10 |
Intended uses
- assessment of microcirculation dysfunction in diabetes, cardiovascular diseases, and hypertension,
- prognosis of the healing process in chronic wounds (including diabetic foot ulcers),
- assessment of physical exercise tolerance in amateur and competitive sports,
- assessment of adaptation to high altitudes,
- identification of patients in possible need of preventive or therapeutic interventions.
Summary
The FMSF technique appears to be uniquely suited to the analysis of basal flowmotion and its hypoxia response, and may be used for characterization of microcirculatory status. The FMSF technique enables disorders to be detected at an early stage of development and facilitates monitoring of the treatment process.Publications:
