Understanding How The Oxygen Study Was Conducted
To be included in the study, patients had to be diagnosed diabetes and have a non-healing, full-thickness foot wound. These individuals had to meet the standard classification, known as the University of Texas Classification grade 1 or 2 diabetic foot ulcer, measuring more than 0.39 of an inch but less than 7.8 inches after surgical removal of unhealthy tissue .2 On average, patients were in their 60th decade of life.
These patients had had food ulcers for as little as a month and lasting up to one year, and they had been receiving the standard care during this time. According to the American Podiatric Medical Association, several factors are key in the typical management of foot ulcers, such as preventing infection, taking pressure off the area , removing dead skin and tissue , topical medications or dressings, as well as assuring that patient is under care for blood glucose management and related health issues.1
After three months of treatment, 15 of the wounds that were present at the beginning of the study were completely healed in the group getting active oxygen therapy but only 5 wounds, or 13.5%, in the group receiving no treatment .
Put another way, those receiving the pure oxygen were 4.5 times more likely to have their foot ulcer heal. After the researchers took into account the severity of the ulcers, the patients on the oxygen showed even greater improvement6 times more likely to completely healover the 12 weeks.
Vitamin E For Immunity And Recovery
Vitamin E is essential for the optimal functioning of the body. In the case of foot ulcers too, vitamin E produces amazing results. Vitamin E speeds up the healing process. It also improves the circulation of blood in the body. A proper supply of blood and oxygen to the wounded region prevents the wound from getting infected.

Reasons Diabetes May Lead To Amputation
Uncontrolled blood sugar can lead to numerous diabetes health complications, including peripheral artery disease and peripheral neuropathy .
PAD, common in people with diabetes, causes blood vessels to narrow, restricting blood flow to the feet and legs. Reduced blood flow causes wounds to take a longer time to heal. For example, an injury that starts small may turn into an infection that doesn’t heal, leading to tissue death or a further spread of infection.
Nerve damage can also cause foot or toe amputation if numbness keeps you unaware of foot injuries. If such wounds go undetected and untreated, they can lead to a bad infection.
PAD and neuropathy make it easier to develop ulcers or infections that raise the risk of amputation.

Symptoms Of Foot Ulcers
Foot ulcers may look almost like a wound on the flesh of the foot. Key points about ulcer and their appearance:
Summary:
The symptoms of the foot ulcer are different from person to person. If you notice any change of skin color or a wound around the foot, consult the doctor.
The cause of diabetic foot ulcers is mainly due to the following:
- Poor blood circulation
- Feet irritated or wounded
Due to vascular disease, the blood flow is not proper in the body. This results in poor blood circulation and results in leg swelling, blood clots, etc. These can cause ulcers in the inner part of the leg just below the knees.
Summary:
Diabetes, poor circulation, nerve damage, swelling in lymph, and improper diabetes management are causes of foot ulcers.

Can My Foot Ulcers Be Treated
Yes. Lets take a look at some of the foot ulcer treatments and methods that your doctor may recommend or perform:
- Avoiding putting weight on the ulcerated foot. Your doctor may fit you with a cast, special boot, or surgical shoe that keeps pressure off the area.
- Maintaining blood sugar levels in order to facilitate healing.
- Medical debridement of your injury, which will involve your doctor removing the infected tissue so the healthy tissue below can heal over the wound.
- Keeping the ulcer dry by covering it with appropriate wound dressings. Clean the wounds each day and re-cover them with fresh wound dressings in order to encourage healing of the ulcer.
With proper treatment and if caught early, a diabetic foot ulcer can show massive improvement within a week. If left untreated, and if the ulcer does not heal, it can worsen over time which may lead to amputation of one or more toes or the foot in order to stop the infection and save your life.
After The Ulcer Has Healed
Once you have had a venous leg ulcer, another ulcer could develop within months or years.
The most effective method of preventing this is to wear compression stockings at all times when you’re out of bed.
Your nurse will help you find a stocking that fits correctly and that you can manage yourself.
Various accessories are available to help you put them on and take them off.

Cleaning And Dressing The Ulcer
The first step is to remove any debris or dead tissue from the ulcer, wash and dry it, and apply an appropriate dressing. This provides the best conditions for the ulcer to heal.
A simple non-sticky dressing will be used to dress your ulcer. This usually needs to be changed 1 to 3 times a week.
Many people find they can manage cleaning and dressing their own ulcer under the supervision of a nurse.
How To Prevent Diabetic Foot Ulcers
The first line of defense in preventing diabetic wounds is to follow the guidelines recommended to keep the disease itself under control:
- Maintain healthy blood sugar levels through a healthy diet and by taking medications as instructed by your doctor.
- Keep your blood pressure within a healthy range.
- Avoid alcohol and tobacco.
You should also take measures to avoid causing sores or wounds on the feet:
- Never walk barefoot.
- Wear shoes that fit properly and dont rub the skin.
- Wash your feet daily with mild soap and lukewarm water to prevent the buildup of bacteria on the skin, which can cause infection even in the tiniest skin breaks.
Because a loss of sensation in the feet may mean theres no pain felt even when an ulcer is present, its also extremely important for those with diabetes to regularly check for any foot sores or skin irritation. This way, the ulcer can be properly treated as early as possible.

How Should A Diabetic Foot Ulcer Be Treated
The primary goal in the treatment of foot ulcers is to obtain healing as soon as possible. The faster the healing of the wound, the less chance for an infection.
There are several key factors in the appropriate treatment of a diabetic foot ulcer:
- Prevention of infection
- Taking the pressure off the area, called off-loading
- Removing dead skin and tissue, called debridement
- Applying medication or dressings to the ulcer
- Managing blood glucose and other health problems
Not all ulcers are infected however, if your podiatric physician diagnoses an infection, a treatment program of antibiotics, wound care, and possibly hospitalization will be necessary.
Preventing Infection
There are several important factors to keep an ulcer from becoming infected:
- Keep blood glucose levels under tight control
- Keep the ulcer clean and bandaged
- Cleanse the wound daily, using a wound dressing or bandage
- Do not walk barefoot
Off-Loading
For optimum healing, ulcers, especially those on the bottom of the foot, must be off-loaded. Patients may be asked to wear special footgear, or a brace, specialized castings, or use a wheelchair or crutches. These devices will reduce the pressure and irritation to the ulcer area and help to speed the healing process.
Applying Medication and Dressings
For a wound to heal there must be adequate circulation to the ulcerated area. Your podiatrist may order evaluation test such as noninvasive studies and or consult a vascular surgeon.
Managing Blood Glucose
Diabetic Foot Ulcer: Treatment And Prevention
Estimates are that by 2030 there will be 550 million individuals with diabetes in the world. Because almost a quarter of all people with diabetes will develop a foot ulcer at some point, health care workers need to know the best practices for diabetic foot ulcer prevention and treatment.
Determining which diabetic foot ulcer type is important to determine an effective treatment. Here are the different types of these wounds:
- Neuropathic ulcers arise when the nerve damage from diabetic neuropathy causes the individual with diabetes to not feel pain from an injury, which often leads to the ulcer progressing substantially before the person is even aware of it. Foot and toe deformities, corns, calluses and areas repetitive stress are likely places of injury. Footwear can not only hide these issues, but can exacerbate the injury if the shoe is ill-fitting.
- Ischemic ulcers or arterial ulcers as they are sometimes called may occur due to lack of blood flow to the extremity. When an ulcer occurs as the result of an injury to the extremity, the lack of blood flow makes these ulcers difficult to heal.
- Neuroischemic ulcers occur in individuals with both neuropathy and poor arterial blood flow and are the most difficult to heal.
- Infected wounds occur in about half of patients with a diabetic foot ulcer and require particularly close care.

What Does A Diabetic Foot Ulcer Look Like
A diabetic foot ulcer looks like a crater on the foot. It can be shallow, only penetrating the surface of the skin, or it can involve deep tissue penetration. Tendons and bones in the foot can be affected along with other deep structures. Often, there will be an open wound in the middle of the crater that varies in size, depending on the severity of the ulcer.

Common Diabetic Foot Ulcer Symptoms
Wounds can develop anywhere on the body, but diabetics are most vulnerable to cuts, scrapes, and sores on their feet. In fact, diabetic foot injuries are the most common cause of hospitalization among diabetic patients. Its critical for every diabetic to learn how to identify foot ulcers in order to stop the cycle of injury before it requires an amputation.

What Wounds And Ulcers Are Commonly Confused With Diabetic Foot Ulcers
There are several types of ulcers and wounds that can mimic a diabetic foot ulcer. Venous and arterial ulcers are both open sores that are often found on the lower extremities of the body, frequently the feet. Arterial ulcers are the resulting development from arterial damage from inadequate blood flow to the tissues.
Physicians must exercise high levels of attention to detail when assessing the difference between a diabetic foot ulcer and malignant melanoma. Malignant melanoma on the foot is frequently mistaken for a diabetic foot ulcer. There is a great need for biopsy in the early stages of foot ulcers. This is the only way that the rate of misdiagnosis can be reduced, and this erroneous diagnosis can be critical.
What Can Caregivers And Loved Ones Do To Contribute To Prevention
Education and instruction on the proper process for general foot care should be available to the patient and family, especially anyone who carries the most responsibility for daily care. General foot care steps include:
- Daily foot washing
- Drying the feet thoroughly
- Proper moisturization
If the patients feet are not sweating or visibly dirty, a little means a lot when it comes to soap. Older patients already have reduced natural body oil, so it is necessary to preserve the moisture that is there. Moisturizing soaps are recommended. If bedside bathing is necessary, a few drops of baby oil can be added to the water for extra moisturization followed by moisturizing lotion after the body has been patted dry. Getting dressed for the day after moisturizing is important, as the clothing will easily slide over the lotioned limbs.
Do not apply moisturizer between the toes of the foot, as this can promote fungal growth. If excessive feet sweat is an issue, roll-on antiperspirant can be applied to the soles of the feet before putting on socks.
Socks and shoes should always be worn whether the patient is in a wheelchair or not. Footwear is not for walking, but for protection, in diabetics. Shoes are barriers between toes and items a patient may kick accidentally and a support structure. Footrests should be kept on wheelchairs. When the patient is pushed, they may be dragging their feet and not even realize it, and an injury can be sustained.
