Issues
The main concern is the higher cost, challenges in training HCWs to
safely remove PAPRs without contamination, the need for re-training if
infrequently use, inability to re-use disposable filters between
patients, the need for explicit decontamination and recycling of blower
units, potential compromise of disposable components through
inappropriate attempts to sterilise and reuse to conserve supply leading
to infection risk, communication challenges due to the fan noise, and
increased risk of infection from doffing the additional layers of
PPE.(1, 23, 100, 104)
