No smoking or allowing others to smoke; post signage outside the home for visitors prior to entry. Store properly (e.g., upright, as the tank can roll away).
What is oxygen Wound Therapy?
Hyperbaric oxygen therapy involves exposing the body to 100% oxygen at a pressure that is greater than normal. . Wounds need oxygen to heal properly. Exposing a wound to 100% oxygen may speed healing. Hyperbaric oxygen therapy can be done in a number of ways.
What are oxygen treatments called?
Hyperbaric oxygen therapy (HBOT) is a type of treatment used to speed up healing of carbon monoxide poisoning, gangrene, wounds that won't heal, and infections in which tissues are starved for oxygen.
How does hyperbaric oxygen help heal a wound?
During the treatments, the patient breathes 100 percent oxygen inside a pressurized chamber, quickly increasing the concentration of oxygen in the bloodstream, where it is delivered to a patient's wound site for faster healing. Essentially, HBO therapy helps heal the wound from the inside out.
What types of infections can be treated using hyperbaric oxygen?
HBOT is used as either a primary or adjunctive treatment in the management of infections such as gas gangrene, necrotizing fasciitis, diabetic foot infections, refractory osteomyelitis, neurosurgical infections and fungal infections.
What does an oxygen therapy treatment do?
The extra oxygen moves through your blood and to your organs and body tissues. HBOT is used to treat certain serious wounds, burns, injuries, and infections. It also treats air or gas embolisms (bubbles of air in your bloodstream), decompression sickness suffered by divers, and carbon monoxide poisoning.
How does hyperbaric treatment work?
Hyperbaric oxygen therapy increases the amount of oxygen your blood can carry. With repeated scheduled treatments, the temporary extra high oxygen levels encourage normal tissue oxygen levels, even after the therapy is completed. Hyperbaric oxygen therapy is used to treat several medical conditions.
What are the side effects of hyperbaric treatment?
Side effects and possible complications of HBOTLung damage.Fluid buildup or bursting (rupture) of the middle ear.Sinus damage.Changes in vision, causing nearsightedness, or myopia.Oxygen poisoning, which can cause lung failure, fluid in the lungs, or seizures.
Why would the patient be ordered to have hyperbaric therapy at the wound care center?
HBOT enhances oxygen-rich blood flow to overcome the effects of radiation and trigger deep healing along uncomfortable radiation wounds. This saves cancer survivors from additional health dangers and stops potential infection in its tracks.
Who is not a candidate for hyperbaric oxygen therapy?
The one absolute contraindication to hyperbaric oxygen treatment is a patient with an untreated pneumothorax. All patients should have lung imaging before treatment.

Do I need a prescription for hyperbaric oxygen therapy? Yes, a prescription is required for HBOT. You will meet with our medical director for a consultation to determine if your condition may benefit from HBOT. After a prescription is written, a series of specified treatments can be scheduled.
Why is oxygen important for healing?
Oxygen is vital for healing wounds. It is intricately involved in numerous biological processes including cell proliferation, angiogenesis, and protein synthesis, which are required for restoration of tissue function and integrity.
What is wound healing?
Wound healing isa dynamic and carefully orchestrated process involving blood cells, cytokines, parenchymal cells (i.e.,fibroblasts), and extracellular matrix reorganization. In the normal wound, this interactive process ultimately restores dermal and epidermal functional integrity in a sequential and timely fashion.
What is the role of HIF stabilizers in wound healing?
As oxygen levels decrease within the wound, cell response mechanisms (hypoxia inducible factor [HIF]) trigger the transcription of genes that promote cell survival and angiogenesis . HIF stabilizers are currently being tested to determine wound healing potential . Clinically, topical oxygen therapy (TOT) has been proved as an effective therapeutic modality for chronic wounds. TOT is reputed to have several advantages over hyperbaric oxygen therapy. Namely, TOT has a lower risk of oxygen toxicity, it is less expensive and is relatively easy to apply to target areas.
Why do chronic ischemic wounds fail to heal?
Chronic ischemic wounds fail to heal appropriately secondary to extreme hypoxia that leads to cellular demise. Wound tissue hypoxia is typically greater at the center of the wound. Accordingly, oxygen requirements of the regenerating tissue will vary.
What is redox signaling?
Redox signaling and ROS generation is a process reliant on the NADPH oxidase (NOX) family of enzymes. The redox signals produced serve critical roles within the wound bed: (1) they provide the phagocytic immune cells with potent disinfecting capabilities, (2) in physiologic concentrations, they function as signaling molecules that mediate various responses, including cell proliferation, migration, differentiation, gene expression, and vascular tone.7,8
What causes a chronic wound microenvironment?
In the chronic wound microenvironment, there inevitably exists a substantial imbalance between the supply of oxygen and the high energy demand of the healing tissue. From a molecular standpoint, the key factors that propagate this imbalance include the following: (1) the increased utilization of oxygen by the hypermetabolic regenerating tissue, (2) the sustained and increased production of ROS by phagocytes (respiratory burst), and (3) reduction-oxidation (redox) signaling.1
What is the key moderator of wound healing?
A key moderator of normal wound healing is oxygen. Indeed, oxygen is a requirement for various processes in the healing of wounds including collagen deposition, epithiliazation, fibroplasia, angiogenesis, and resistance to infection.
How is oxygen delivered?

Although oxygen therapy may be common in the hospital, it can also be used at home. There are several devices used to deliver oxygen at home. Your healthcare provider will help you choose the equipment that works best for you. Oxygen is usually delivered through nasal prongs (an oxygen cannula) or a face mask.
Why is oxygen important for wound healing?
Continuous supply of oxygen to the tissue through microcirculation is vital for the healing process and for resistance to infection. Evaluation of tissue perfusion and oxygenation is important in all types of wound patients. Monitoring systems should measure the hemodynamic situation and the ability of the cardiovascular system to deliver an adequate volume of oxygen to meet the metabolic demands of the peripheral tissue. Oxygen therapy is important in relation to both healing and resistance to infections. External factors have been shown to significantly decrease the peripheral oxygen supply, and supplementary perioperative oxygen to reduce the surgical wound infection rate by one- half in patients undergoing colorectal resection. Hyperbaric oxygen therapy may be beneficial in situations where the nutritive flow and oxygen supply to the healing tissue are compromised by local injury, and particularly if anaerobic infection is present. However, the definitive proof for the effect and indications of this therapy in wound healing still has to be established. It can be concluded that adequate delivery of oxygen to the wound tissue is vital for optimal healing and resistance to infection. Assessment of perfusion and oxygenation is essential for the wound patient, as well as the treating personnel. The indication for hyperbaric oxygen treatment still needs to be defined. During wound healing the continuity and function of the damaged tissue are re-established. This is only possible through a restoration of the microcirculation and thereby the nutrition to the tissue. The main component of the nutrition is oxygen, which is critically important for healing a wound by production of granulation tissue and for ensuring resistance against infection. This has been shown experimentally, but recently a short period of supplementary oxygen has been shown to decrease wound complications in clinical practice as well.
Why is oxygen therapy important?
Oxygen therapy is important in relation to both healing and resistance to infections. External factors have been shown to significantly decrease the peripheral oxygen supply, and supplementary perioperative oxygen to reduce the surgical wound infection rate by one- half in patients undergoing colorectal resection.

What is the role of fibroblasts in wound healing?
Deposition of collagen is a fundamental step in the wound healing process as it provides a natural scaffold or substrate for new tissue growth. The formation of the collagen triple helix is O 2 dependent. Without the triple helix, procollagen is non-functional. It is these extracellular cross-linkages that are ultimately responsible for the tensile strength needed in prolonged wound healing. 6 Hunt and colleagues used a rabbit model to track the rate and density of collagen formation with changes in oxygen levels. The results demonstrated that exposure to hyperoxic environments accelerated collagen synthesis. 6
What is the role of VEG-F in wound healing?
The formation of new blood vessels, or angiogenesis, is critical in wound healing. This neovascularization provides channels for active cells, nutrients and O 2 to travel to the wounded tissues. Vascular endothelial growth factor (VEG-F) is a major angiogenic stimulus. Initially, hypoxia acts as a stimulus to VEG-F. However, prolonged hypoxia inhibits VEG-F formation and function and obstructs neovascularization. 7 Topical oxygen therapy has been shown to increase both VEG-F levels as well as angiogenesis.
