Unlike hyperbaric oxygen treatment for chronic wounds, oxygen treatment used in this therapy is not systemic in nature and treats only the wound area. This treatment differs from topical oxygen treatments, as topical oxygen typically involves sporadic treatments of 1–3 hours several times per week, while TCOT treatment is 24/7 by nature.
In some cases treatment may extend to improving oxygen capacity of the blood, which may include volumetric and circulatory intervention and support, hyperbaric oxygen therapy and treatment of intoxication. Invasive ventilation may be necessary or an elective option in surgery.

Negative pressure wound therapy (NPWT) is a treatment that improves ischemic tissues and removes wound fluid used by bacteria. [ 8 ] [ 14 ] This therapy, also known as vacuum-assisted closure, reduces swelling in tissues, which brings more blood and nutrients to the area, as does the negative pressure itself. [ 8 ]
Without comorbidities, wounds are thought to be able to heal if the oxygen tension is greater than 40 mmHg. [1] In the presence of comorbidities, such as diabetes or edema, a higher value is likely needed. Patients with oxygen tensions less than 20 mmHg are likely to need revascularization to promote adequate wound healing. [3]
Additionally, oxygen in a confined space can be consumed if carbon dioxide scrubbers are used without sufficient attention to supplementing the oxygen which has been consumed. Hypoxic or anoxic breathing gas mixtures, and exposure to a vacuum or other extreme low pressure environment will remove oxygen from the blood in the alveoli.
Negative-pressure wound therapy (NPWT), also known as a vacuum assisted closure (VAC), is a therapeutic technique using a suction pump, tubing, and a dressing to remove excess wound exudate and to promote healing in acute or chronic wounds and second- and third-degree burns.
Situations that can cause asphyxia include but are not limited to: airway obstruction, the constriction or obstruction of airways, such as from asthma, laryngospasm, or simple blockage from the presence of foreign materials; from being in environments where oxygen is not readily accessible: such as underwater, in a low oxygen atmosphere, or in a vacuum; environments where sufficiently ...
