FAQ – Wounds
What stages does the therapy work?
PhotoMed’s studies welcomed people unexpected to improve. Some had years-old wounds or diabetic ulcers that were worsening. Others had fresh wounds from pets and nicks while on blood thinners. Immaculately cleaned wounds typically didn’t have fresh blood exude like wounds with biofilms. Moist wounds appear to be the most responsive.
Scars may respond by flattening, becoming suppler, and less itchy. People with spinal cord stimulators have reported cessation of rupturing of stitches and overall faster recovery. Otherwise healthy people also remark that their wounds healed faster than expected.
Bruising in people on blood thinners may change from yellowish to dark within minutes. Subjects reported that clearing the bruise took days instead of weeks.
What can I see during treatment?
To be stimulated, the material must absorb light. In white light, colored stuff looks the color of wasted photons. That is, red material turns relatively dark in green or blue wavelengths. Varying the wavelength (Vari-Chrome Pro setting #2) through orange to yellow-green lets the operator see the wound with varying contrast during treatment. Exudates typically become visible as tiny dots 1-3 minutes after therapy begins. If nothing happens during a treatment, try a different wavelength. About 10 minutes total should get things going, or not.
Wound specialists have remarked about early changes, such as granulation, or tension around the margin.
You can see that 50nm change in wavelength makes a big difference in absorption (relatively darker). https://www.photomedtech.com/fresh-exudates
Why does it work so fast?
We don’t know. It just does.
Speculators have suggested that the wound stalls just like pain for unknown reasons. (Wounds meet the definition of pain.) The appearance of fresh exudate typically occurs on a similar timescale as for other impaired functions. Could the wounds exhibit a switch from an impaired state to “normal” such that the next step progresses, irrespective of wound state?
Other speculators suggest that the varying wavelengths differentially stimulate wavelength-sensitive molecules. This line of thinking suggests that the body exquisitely ignores signals from a broad range of wavelengths, such as sunlight. The differential model accounts for the lack of response from the application of a fixed wavelength.
The Instant Verification System is ready when some researcher wants to check out the various speculations.
What settings for a scabbed-over wound?
The color of the scab presents a barrier to getting the “right” wavelength to the interior of the wound. Applying a similar color may penetrate the scab. Red (Vari-Chrome Pro setting #1) may prompt generally increased blood circulation and reduction of inflammation. Varying wavelength from about 630-690nm traverses wavelengths used by red lasers and LED devices.
Could pain prevent wound healing?
Maybe. People with pain and wounds frequently have general health problems, diabetes for example.
That said, a practitioner reported that an abdominal wound from a shotgun blast began to heal after a single treatment for intractable pain in the man’s feet (no one thought that the wound would restart). Granulation became visible by the second day. Images are available on request.
Does this therapy work better than laser therapy?
No comparisons were made, PhotoMed’s studies were for developing its algorithms. Our team gave up know precisely which wavelength “works” in favor of efficiency of restarting healing.
High-powered red and infrared wavelengths may penetrate deeper tissue that could be responsible for the “stuck” process.
Why do you only talk about restarting wound healing?
The goal is to enable the practitioner to objectively document resumed processes during the first visit. When the patient leaves the clinic, the possible associations with the therapy weaken. Before and after images with the same lighting may show changes in the blue channel that might be missed in the full color image.
Could the Instant Verification System™ be used in an every-day clinic?
Yes, but it would likely be used for special occasions. Most wounds become boring after operator has seen a dozen or two fresh-exudate responses.
PhotoMed’s high resolution camera (4k HDR monochrome) fills a hard drive at about 3Gb/minute. We use a monochrome camera that can “see” all the visible wavelengths with a single sensor. The illuminating wavelength is recorded from the Vari-Chrome® Researcher for embedding in the output MP4s from PhotoMed’s playback module.
