Oxygen therapies, including hydrogen peroxide and ozone treatments, are unproven cancer cures lacking scientific evidence. These dangerous alternatives have led to adverse events and deaths, distinct from legitimate respiratory care.
Area of Science:
- Alternative Medicine
- Oncology
- Immunology
Background:
- Oxygen therapies are promoted as cures for serious illnesses like cancer and acquired immune deficiency syndrome (AIDS).
- Clinics in Mexico, the US, and Europe offer these unproven treatments.
- Proponents falsely claim oxygen deficiency causes disease and that oxygenation can restore health.
Purpose of the Study:
- To evaluate the scientific validity of oxygen therapies.
- To identify the types and claims associated with oxygen therapies.
- To document the safety and adverse outcomes of oxygen therapies.
Main Methods:
- Review of scientific literature and clinical evidence.
- Analysis of claims made by proponents of oxygen therapies.
- Documentation of reported adverse events and patient outcomes.
Main Results:
- There is no scientific evidence to support any claims made for oxygen therapies.
- Oxygen therapies include hydrogen peroxide treatments (intravenous, ingestion, colonic, topical) and ozone therapies (autohemotherapy, colonic).
- Reported adverse events include serious harm and fatalities.
Conclusions:
- Oxygen therapies are unproven and lack scientific support for treating cancer, AIDS, or other diseases.
- These therapies pose significant health risks, including death.
- Oxygen therapies should not be confused with standard medical oxygen used in respiratory care.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
Administering Oxygen by Mask
Administering oxygen by mask is a common nursing intervention that provides supplemental oxygen to patients with respiratory distress or chronic lung conditions. This procedure involves delivering oxygen at a specified rate through a face mask connected to an oxygen source.
