Pressure Injuries in Elderly Patients: Prevention, Staging, and Treatment with HBOT

Pressure injuries, formerly known as bedsores or pressure ulcers, are a significant health concern for elderly patients, particularly those with limited mobility. These wounds develop when sustained pressure on the skin reduces blood flow to the tissue, causing it to break down. At Elite Wound Care Center in Palm Harbor, we treat pressure injuries at all stages and help patients and caregivers develop prevention strategies.

Why Elderly Patients Are at Higher Risk

Aging brings several changes that increase susceptibility to pressure injuries. The skin becomes thinner and more fragile, losing the protective padding of subcutaneous fat. Circulation naturally decreases with age, meaning tissues receive less oxygen and fewer nutrients. Reduced mobility from conditions like arthritis, stroke, or dementia means some patients spend extended periods in the same position. Nutritional deficiencies, particularly inadequate protein intake, further impair the skin's ability to withstand pressure and repair itself.

Understanding the Stages

Pressure injuries are classified into four stages based on severity. Stage 1 presents as a non-blanchable area of redness on intact skin. The skin may feel warmer or cooler than surrounding tissue. Stage 2 involves partial-thickness skin loss with a shallow, pink wound bed. It may also present as an intact or ruptured blister. Stage 3 extends into the subcutaneous fat layer, creating a deeper wound. Undermining and tunneling may be present. Stage 4 is the most severe, with full-thickness tissue loss that may expose muscle, tendon, or bone. These wounds carry a high risk of serious infection.

Prevention Strategies

Prevention is always preferable to treatment. Key strategies include repositioning the patient at least every two hours, using pressure-redistributing mattresses and cushions, keeping skin clean and dry, maintaining adequate nutrition with emphasis on protein and vitamin C, conducting daily skin inspections with particular attention to bony prominences like the sacrum, heels, hips, and shoulder blades, and managing moisture from incontinence to prevent skin maceration.

How HBOT Helps Heal Pressure Injuries

For stage 3 and stage 4 pressure injuries that are not responding to standard wound care, HBOT can be a valuable addition to the treatment plan. The therapy increases oxygen delivery to the compromised tissue, stimulates new blood vessel formation in the wound bed, enhances collagen production for stronger tissue repair, and boosts immune function to help control bacterial contamination.

HBOT is particularly effective when the pressure injury is located in an area with naturally limited blood supply, such as the sacrum or heels, where healing is often slow due to the distance from major blood vessels.
