INTRODUCING EXHALED HUMAN BREATH WATER VAPOR AS PROPOSED MECHANISM INFLUENCING SUPERFICIAL CUTANEOUS WOUND HEALING

Abstract [English]

The concept that moist wounds heal faster than dry wounds was introduced in 1962. Most recently, in 1990 the concept was revisited with the introduction of a highly permeable wound dressing exposed to water vapors. The latter allows for water as a humidifying agent. Ideally, acceleration of superficial wound healing had been accomplished by the introduction of a highly water vapor permeable wound dressing. The breathable property allows for water vapor to interact with already present fibrin(ogen) material in blood clots. This manuscript adds a mechanism for the ultimate undisturbed success in cutaneous wound healing, being the dependency on a continuos supply of water vapor. In vitro experiments are introduced showing the cessation of exhaled human breath vapor onto a dry human blood smear as the end point of said interaction. Additionally the experiments were reproduced by exposing the blood smears to steam (water vapor) generated by machinery. In conclusion, exhaled human breath water vapor blown onto a blood clot has the same effect as water vapor emitted by machinery boiling water. Both causing a disappearance of the clot organized fibrin strands into a semisolid gelatinous state. Additionally, discontinuation of the water vapor infusion is also documented triggering a return of organized fibrin strands, albeit of greater intensity.
