Contraindications for oxygen therapy are generally relative, meaning caution should be exercised, and the benefits weighed against the risks. There are few absolute contraindications. Here's a breakdown:
Relative Contraindications
| Condition | Reason for Caution | Considerations |
|---|---|---|
| COPD (Chronic Obstructive Pulmonary Disease) | Potential loss of hypoxic drive to breathe | High concentrations of oxygen can suppress the respiratory drive in some COPD patients. Titrate oxygen carefully, aiming for SpO2 of 88-92%. |
| Eustachian Tube Dysfunction | Risk of barotrauma to the tympanic membrane | Relevant in hyperbaric oxygen therapy, where rapid pressure changes can occur. Avoid rapid pressure changes. |
| High Fever | Higher risk of seizures | Oxygen therapy itself doesn't directly cause seizures, but hyperbaric oxygen therapy can lower the seizure threshold in some cases, especially with high fever. Manage fever aggressively. |
| Pacemakers or Epidural Pain Pumps | Potential malfunction or deformation under pressure | Primarily a concern in hyperbaric oxygen therapy due to pressure effects. Evaluate the specific device and consult with the manufacturer. |
Considerations for Hyperbaric Oxygen Therapy (HBOT)
HBOT involves breathing 100% oxygen in a pressurized chamber. It has specific contraindications beyond those for general oxygen administration:
- Untreated Pneumothorax: HBOT can worsen a pneumothorax (collapsed lung).
- Certain Medications: Some medications, such as bleomycin, doxorubicin, disulfiram, and cisplatin, can increase the risk of pulmonary toxicity or other adverse effects during HBOT.
- Pregnancy: While not an absolute contraindication, HBOT should be used cautiously during pregnancy, weighing the potential benefits against the risks to the fetus.
Important Note: Always consult with a qualified healthcare professional to determine the appropriate course of treatment and to assess any potential risks or contraindications for oxygen therapy or hyperbaric oxygen therapy.
