Official Description

Noncontact near-infrared spectroscopy studies of flap or wound (eg, for measurement of deoxyhemoglobin, oxyhemoglobin, and ratio of tissue oxygenation [StO2]); image acquisition only, each flap or wound

Common Language Description

Noncontact near-infrared spectroscopy (NIRS) is a sophisticated imaging technique utilized for the assessment of wounds and skin flap oxygen perfusion through the application of light. This method enables the calculation of the percentages of oxygenated hemoglobin (oxyhemoglobin) and deoxygenated hemoglobin (deoxyhemoglobin), as well as the ratio of tissue oxygenation (StO2). These measurements are critical for predicting wound healing, evaluating the viability of skin flaps, and determining the success of biologic wound matrix applications. The principle behind NIRS is based on the relative transparency of tissue to near-infrared light, which reflects differently depending on the oxygenation levels present in the blood. By utilizing a noncontact hand-held imaging device, such as SnapshotNIR, healthcare professionals can measure the oxygenation levels within the capillary bed without direct contact with the skin. The device emits six near-infrared electromagnetic wavelengths of light, which are absorbed variably by oxygenated and deoxygenated hemoglobin molecules. The light that is not absorbed is reflected back to the device, where it is recorded for analysis. Proprietary calculation software processes the return signal to assess the oxygen saturation level at each pixel, resulting in a color-coded map that visually represents the oxygenation status alongside the clinical image. This data is then interpreted to generate a comprehensive report detailing the healing progress or viability of the flap, as well as predicting the healing trajectory. Such information is invaluable in mitigating risks associated with wound healing and enhancing patient outcomes.

1. Indications

Noncontact near-infrared spectroscopy studies are indicated for the assessment of various conditions related to wound healing and skin flap viability. The following are the specific indications for performing this procedure:

Wound Assessment Noncontact near-infrared spectroscopy is utilized to evaluate the oxygenation status of wounds, which is crucial for determining the healing potential and necessary interventions.
Skin Flap Viability This procedure helps in assessing the viability of skin flaps, ensuring that adequate blood flow and oxygenation are present for successful healing.
Monitoring Healing Progress The technique is employed to monitor the healing trajectory of wounds and flaps over time, providing valuable data for treatment planning.
Evaluation of Biologic Wound Matrix Applications NIRS is used to assess the effectiveness of biologic wound matrix applications by measuring tissue oxygenation levels.

2. Procedure

The procedure for conducting noncontact near-infrared spectroscopy studies involves several key steps that ensure accurate image acquisition for the assessment of flaps or wounds. The following procedural steps are outlined:

Step 1: Preparation of the Patient The patient is positioned comfortably, and the area of interest is exposed to allow for unobstructed access. It is essential to ensure that the skin is clean and free from any obstructions that may interfere with the imaging process.
Step 2: Device Setup The noncontact hand-held imaging device, such as SnapshotNIR, is prepared for use. The operator ensures that the device is functioning correctly and is calibrated according to the manufacturer's specifications.
Step 3: Image Acquisition The device is held over the flap or wound area without making contact with the skin. The device emits six near-infrared electromagnetic wavelengths of light, which penetrate the tissue and interact with the hemoglobin present in the blood. The reflected light is captured by the device, which records the data for analysis.
Step 4: Data Processing The proprietary calculation software processes the captured data, assessing the oxygen saturation levels at each pixel based on the return signal. This analysis generates a color-coded map that visually represents the oxygenation status of the tissue.
Step 5: Reporting The results of the imaging study are compiled into a report that details the oxygenation levels, healing progress, and viability of the flap or wound. This report is essential for guiding clinical decision-making and treatment planning.

3. Post-Procedure

After the noncontact near-infrared spectroscopy study is completed, there are several considerations for post-procedure care. The patient may resume normal activities immediately, as the procedure is noninvasive and does not require any recovery time. The clinician will review the report generated from the imaging study to assess the healing progress and viability of the flap or wound. Based on the findings, appropriate follow-up care and treatment plans will be discussed with the patient. Continuous monitoring may be recommended to track the healing trajectory and make necessary adjustments to the treatment approach as needed. It is important for healthcare providers to communicate the results effectively to the patient and ensure that any questions or concerns are addressed.
