Air & Gas Embolism

Hyperbaric oxygen is the definitive treatment for air and gas embolisms

HBOT is the primary medical treatment for resolving decompression sickness and air or gas embolisms. A retrospective review of 656 cases showed 78% full recovery rate with HBOT.

Understanding air and gas embolisms and why HBOT is the primary treatment

Air and gas embolisms occur when gas bubbles enter the bloodstream and obstruct blood flow in blood vessels. This blockage leads to tissue hypoxia, inflammation and organ damage, with symptoms ranging from joint pain and dizziness to severe neurological and cardiopulmonary complications. Decompression sickness (DCS) is a related condition affecting divers who surface too quickly, causing dissolved nitrogen to form bubbles in the body.

HBOT is the definitive and primary medical treatment for both conditions. By increasing atmospheric pressure in the chamber, gas bubbles shrink and dissolve back into the bloodstream, restoring normal blood flow. Simultaneously, the 100% oxygen dramatically increases plasma oxygen concentration, ensuring tissues receive adequate oxygen even while bubbles are being resolved. Prompt HBOT administration is critical for preventing permanent neurological and systemic damage.

  • Joint pain, dizziness, fatigue and shortness of breath

  • Neurological symptoms including confusion and paralysis

  • Cardiopulmonary complications from blocked blood flow

  • Risk of permanent organ and tissue damage without treatment

How pressurized oxygen dissolves gas bubbles and restores blood flow

HBOT addresses air and gas embolisms through multiple mechanisms that resolve the bubbles and heal the damage they cause.

Reduces gas bubble size and volume

Enhances oxygen delivery to ischemic tissues

Counteracts ischemic injury from blocked blood flow

Accelerates nitrogen elimination from the body

Supports neovascularization in damaged areas

Reduces inflammation and reperfusion injury

Clinical evidence for HBOT in air and gas embolism treatment

Hyperbaric oxygen therapy is the established standard of care for air and gas embolisms and decompression sickness, supported by decades of clinical evidence.

Bubble reduction mechanism: The primary mechanism of HBOT involves reducing gas bubble size through increased atmospheric pressure (Boyle's Law). As chamber pressure increases, gas bubbles shrink proportionally, reducing their ability to obstruct blood vessels. The smaller bubbles are then reabsorbed into the bloodstream and eliminated through respiration.

Clinical outcomes: A retrospective review of 656 cases showed that patients treated with HBOT had a significantly higher rate of full recovery (78%) compared to those who did not receive HBOT (56%). The mortality rate for HBOT-treated individuals was substantially lower, confirming HBOT's effectiveness in managing air and gas embolisms.

Cerebral arterial gas embolism: A systematic review and meta-analysis published in Critical Care Journal indicates that early initiation of HBOT for cerebral arterial gas embolism (CAGE) is associated with significantly better neurological outcomes. Efficacy decreases as treatment initiation is delayed, emphasizing the critical importance of prompt HBOT administration.

Tissue protection: Beyond bubble reduction, HBOT protects tissues through enhanced oxygen delivery to ischemic areas, accelerated nitrogen elimination, reduced inflammatory response, prevention of leukocyte adhesion to damaged endothelium, and attenuation of ischemia-reperfusion injury. These combined mechanisms prevent the secondary damage that causes long-term complications.

Neovascularization: HBOT promotes the formation of new blood vessels in areas affected by embolism, supporting tissue recovery and reducing long-term complications from vascular damage.

HBOT reduces the size of gas bubbles and enhances their absorption, effectively restoring normal blood flow and oxygenation to affected tissues

A systematic review and meta-analysis indicate that early initiation of HBOT for cerebral arterial gas embolism (CAGE) is associated with significantly better outcomes. The study showed that starting HBOT within the first few hours post-injury maximizes the likelihood of favorable neurological recovery, with efficacy decreasing as treatment initiation is delayed

Hyperbaric oxygen is among the most studied and frequently reported applications in the treatment of delayed radiation injuries. This application of hyperbaric oxygen to the treatment and prevention of delayed radiation injury will be the topic of this chapter. The management of delayed radiation injury, especially when bone necrosis is present, requires mult-disciplinary management. The nature of delayed radiation injury, the mechanisms whereby hyperbaric oxygen is effective, clinical results, the effects of hyperbaric oxygen on cancer growth and future areas for research will be discussed.

TESTIMONIALS

Patient experiences after embolism treatment

Lisa St John, the clinic director for Bay Area Hyperbarics, had chronic refractory osteomyelitis that lasted seven years with no relief. The infection induced severe fatigue and cognitive impairment that prevented her from working and required her to sleep up to 18 hours per day. Finally, a physician recommended hyperbaric oxygen therapy with antibiotics, which after 60 osteomyelitis treatments, healed her. Shortly after being healed, she sold her home to begin her first hyperbaric oxygen therapy clinic, which she has owned for 25 years!

Lisa, 44

Jennifer had osteomyelitis of the lower jaw (mandible), which proved difficult to heal. Her teeth were becoming loose, and her doctor thought she would need surgery. However, he prescribed hyperbaric oxygen therapy before the surgery, and after 60 osteomyelitis treatments, her chronic refractory osteomyelitis healed completely, regrowing bone in her mandible. Jennifer was able to keep her teeth, and was able to return to her active lifestyle, hiking regularly with her husband.

Jennifer, 68

How it works

Emergency treatment protocol for air and gas embolisms

Air and gas embolisms require urgent treatment. Contact us immediately if you suspect an embolism.

1

Urgent assessment and immediate pressurization

Our medical team evaluates the severity and type of embolism to determine the appropriate treatment pressure, oxygen concentration and session duration.

Laptops
2

HBOT sessions to dissolve bubbles and restore oxygen

You breathe 100% oxygen at increased atmospheric pressure. The combination of pressure and oxygen shrinks bubbles and restores blood flow. Acute cases may require multiple sessions.

Laptops
3

Monitoring and follow-up for complete resolution

We monitor for residual symptoms and neurological effects. Additional sessions may be administered to ensure complete bubble resolution and tissue recovery.
