Contact transmission can occur between nasal cannula prongs and the patient environment.

Contaminants from mold and dust to viruses can potentially transfer onto medical oxygen tubing such as nasal cannula prongs upon contact with surfaces such as beds, chairs, doorknobs, floors, and oxygen flow meters.

In Clinical Infectious Disease, nasal cannula prongs tested positive for Middle East Respiratory Syndrome (MERS).

The O2 FRESH nasal cannula cover keeps nasal cannula prongs from contacting fomites when taken off the patient's face. A fomite is an object or materials which are likely to carry infection. 

"It is worth noting that many environmental swab samples contained MERS-CoV despite daily cleaning and disinfection of the patients' rooms."

"Once a fomite is contaminated, the transfer of infectious virus may readily occur between inanimate and animate objects, or vice versa, and between two separate fomites (if brought together)."

"Currently, laboratory studies, epidemiological evidence, and disinfection intervention studies have generated strong indirect and circumstantial evidence that supports the involvement of fomites as a vehicle in respiratory and enteric virus transmission.”

Off the floor and so much more...O2 FRESH is the new standard of care!

Plastic bags seal in moisture in which bacteria can grow. O2 FRESH cannula prong covers are ventilated.

California State University study showed that putting nasal cannulas into ventilated storage, instead of a sealed plastic bag, "decreases the amount of bacteria and likely minimizes cross-contaminants and re-introduction of large numbers of bacteria in the nose."
