Vaping is the act of inhaling and exhaling the vapor produced by an electronic cigarette or similar device. These devices heat a liquid, often containing nicotine, flavorings, and other chemicals, to create an aerosol that is inhaled into the lungs.Western University’s
Surfactant, a critical layer made of lipids and proteins, is essential for easy breathing by reducing surface tension in the lungs. Without surfactant, it would take more effort to breathe and a person would need mechanical help to do so. The research team was able to study the effects by placing a film of surfactant inside a syringe and, then using a vaping device to push aerosol into the syringe. This allowed the vapor to directly interact with the surfactant. The researchers then mimicked inhaling and exhaling vapor into the syringe 30 times to resemble a standard vaping session.
The team also examined different vaping devices, flavors, additives, and nicotine to see if there were any differences in effects.
