Know Your D'OXYVA

D’OXYVA® (deoxyhemoglobin vasodilator) carbon dioxide pressurized mini gas cartridges (pronounced: DOX-ee-va)

Read the Patient Information and User Manual that comes with D’OXYVA before you start taking it and each time you get a refill. There may be new information. This overview does not replace talking with your doctor about your condition or solution.

D’OXYVA is intended for significant enhancements in the regulation of the autonomic nervous system (ANS) including tissue microcirculation with cellular oxygenation, which is being recognized in a rapidly growing number of published randomized trials leading to a variety of significant outcomes. In short, D’OXYVA has demonstrated outsized improvements in blood circulation, cellular oxygenation, tissue perfusion in the microvessels, micro-, and macro-vascular functions, and neural signal activation in the autonomic nervous system according to randomized human trials.

Microcirculation and autonomic nervous system dysfunction is increasingly regarded by the mainstream scientific medical community as the underlying cause of the most widespread health complications for both the young and elderly. Among other things, restrictions in these processes impede normal organ functions, the flow of antibodies, white blood cells and platelets, and rob the skin and body of oxygen and essential nutrients.

D’OXYVA is a relatively affordable, low-risk, non-invasive, non-toxic, non-opioid, both adjunct and stand-alone solution for the forward-looking health facility and patient wanting to significantly reduce cost of solution and readmission rates, while improving patient compliance.

For example, in controlled human studies with D’OXYVA, severe (Wagner stage II – III) diabetic ulcer wounds typically healed and closed within 4 – 8 weeks with an average 2 applications per day and 125 total, costing about $1,500 at out-of-pocket retail price. In comparison, according to various market research studies such as conducted by the Mayo Clinic, the direct cost to treat such wounds with existing modalities yielding only 15 – 20% success is roughly $6,000 – $20,000 annually in the U.S. (not counting indirect cost estimates that are multiples of direct cost) that affects well over 7 million people in the U.S. alone.

The recommended average starting dose of D’OXYVA is 16g CO2 twice daily for 5 days per week for the first 2 weeks and once daily for 5 days per week for another 2 weeks. The average maintenance application frequency of D’OXYVA can be once a day for 3 days per week. The starting and maintenance dose of D’OXYVA should be individualized according to patient characteristics such as goals of solution and response.

Blood flow (perfusion index), oxygen (SpO2 and TcPO2), blood pressure, blood glucose, heart rate variability, sympathetic/parasympathetic nerve activity, blood pH, and other vitals should be analyzed within 2 to 4 weeks after starting D’OXYVA and dosage adjusted according to results.

Stopping D’OXYVA after only 4 weeks is not recommended and it may not provide the expected long-term benefits even if major benefits and outcomes were realized!

D’OXYVA is becoming exceptionally advantageous for the patient, health care practitioner, and the entire healthcare system, and is starting to provide substantial cost savings and improvements in quality of life for a wide variety of health complications for people of all ages and backgrounds.

Do not take D’OXYVA if you:

•are pregnant or think you may be pregnant, or are planning to become pregnant. D’OXYVA has never been reported or tested to cause harm to a pregnant woman or an unborn baby. U.S. FDA regulatory compliance requires that you are notified of any potential risks and if you get pregnant, stop taking D’OXYVA and call your doctor right away.

•are allergic to D’OXYVA or any of its ingredients. The active ingredient is purified carbon dioxide.

D’OXYVA has not been studied in children under 10 years of age.

D’OXYVA has never been reported to cause any serious side effects. Mild side effects have happened only to a small number of people such as lightheadedness. Your doctor can monitor you for them. These side effects usually go away after a few applications or if D’OXYVA is stopped.Call your doctor right away if you have:•muscle problems like weakness, tenderness, or pain that happen without a good reason, especially if you also have a fever or feel more tired than usual. This may be an early sign of a rare muscle problem.•muscle problems that do not go away even after your doctor has advised you to stop taking D’OXYVA. Your doctor may do further tests to diagnose the cause of your muscle problems.•allergic reactions including swelling of the face, lips, tongue, and/or throat that may cause difficulty in breathing or swallowing which may require solution right away.•nausea and vomiting.•passing brown or dark-colored urine.•you feel more tired than usual•your skin and whites of your eyes get yellow.•stomach pain.•allergic skin reactions.In clinical studies, patients reported no adverse side effects while taking D’OXYVA.Talk to your doctor or pharmacist if you have side effects that bother you or that will not go away.These are not all the side effects of D’OXYVA. Ask your doctor or pharmacist for a complete list.

•Store D’OXYVA at room temperature, 68 to 77°F (20 to 25°C).

•Do not keep medicine that is out of date or that you no longer need.

•Keep D’OXYVA and all medicines out of the reach of children. Be sure that if you throw medicine away, it is out of the reach of children.

What You Need to know

D’OXYVA has achieved over 90% elimination of all sorts of chronic pain in 100% of subjects either the same day or in a few days, such as from a very high 8 to a very low 1 on the Visual Analog Scale (VAS). Including, but not limited to neuropathy, fibromyalgia, chemo and radiation therapy, chronic wounds, arthritis, osteoporosis, migraine and lower back pain. It significantly helps improve the rest and digestive function (parasympathetic) in the autonomic nervous system in the brain.

Correct. That’s why D’OXYVA’s gentle process demonstrated that it does NOT significantly increase the CO2 content in the blood or tissue and instead reduces the CO2 content per partial pressure of oxygen (O2). This just means D’OXYVA oxygenates the blood and tissue due to inducing the beneficial Bohr effect. In addition, CO2 is a so-called gasotransmitter that signals the autonomic nervous system in the brain to launch protective mechanisms that tend to move a host of critical functions into balance (homeostasis).

Search the terms we use on this site on the internet to learn more and measure your own results at home or with your doctor with a pulse oximeter for one example. Then watch your blood oxygen (SpO2) and perfusion index (peripheral blood flow) rise quickly in just a half an hour and hour that stays elevated for several hours after a single 5-minute D’OXYVA (single 16g cartridge)! Measure results with your blood pressure and blood glucose meter. For example, take it before your workout to boost energy and after for rapid recovery. Take it to restore healthy blood flow for your foot wounds or back pain or headaches. Reduce the risks of major infections, chronic illnesses and skin damage.

Simply by reducing the need to spend on expensive modalities that just don’t work at the underlying problem, they only act as an expensive bandaid. However, with the help of D’OXYVA your body gets to the bottom of the problem and starts regulating critical functions to restore order and even generate new and highly beneficial resources such as vessel structure growth, tissue repair, cell production and other hormonal and neural functions. Take D’OXYVA together with your beloved supplements, vitamins and even necessary medications and treatments to boost their efficacy and likely reduce any negative effects you may be experiencing from some of them.
