Do you know how to use PAPRs?
You should use a positive-air pressure respirator (PAPR) to protect against bacteria and viruses up to 0.3 microns in length if you suspect a patient has smallpox, recommends Darlene Matsuoka, RN, BSN, CEN, CCRN, ED clinical nurse educator at Harborview Medical Center in Seattle. "It should protect against smallpox droplets, but is not a guarantee against the virus itself," she cautions.
At Harborview’s ED, all new nursing staff receive training in tuberculosis given by the employee health department. The training includes discussion about administrative controls such as policies and screening, environmental controls such as isolation rooms, and use of personal protective equipment, including PAPRs. (See "Resources" at the end of this article for information on obtaining PAPRs.) Nurses watch a video on how to check the airflow of the respirator unit by placing a pressure flow cup in the tubing assembly, which is done with each use.
"The hospital switched to the PAPRs because the hoods require only a basic fitting, are not problematic with facial hair, and have no requirements about semiannual testing like the negative-pressured masks," says Matsuoka. "We are a large teaching facility, so the testing requirement was a huge issue." Next, individual departments train nurses and provide the PAPR hoods. "I do it during the "sit-down" ED orientation day, when unit-specific issues are discussed," says Matsuoka.
In the ED, the PAPR hoods are kept in a four-drawer cart in a utility room across the hall from the isolation rooms. "The top drawer holds the flow cups and extra tubing assemblies, the second drawer holds extra hoods of both sizes, and the bottom two drawers are fitted for five PAPRs each with power charging units," she says.
It’s a mistake to assume that a mask will protect you from smallpox, says Sue C. Felt, RN, MS, MPH, CIC, associate hospital epidemiologist and infection control coordinator at San Francisco General Hospital. "All persons who were in the room or the vicinity of the patient should consider themselves exposed and get the vaccine," she says. "Public health should immediately arrange for this through the CDC." Felt says the importance of hand washing can’t be overemphasized. "Hand washing always reduces the risk of transferring illness," she says. "Though smallpox is spread via respiratory route, reminders about hand washing are always appropriate. It is the single most ignored infection control measure, everywhere."
Matsuoka advises limiting the time you spend in the isolation room. "Scrupulous hand washing, as with all body substance isolation practices, is warranted," she stresses.
Other types of personal protective equipment may not protect you from contracting smallpox, according to Felt. "I, myself, would wear an N95 mask — well placed and snug — and hope for the best," she says. "I would hope to get vaccinated within four days."
