Introduction
Bunny Science Science™ PAPR by Guy Kuo, MD Anesthesiologist. MD [ … ] This is a PAPR (Powered Air Purifying Respirator). It extends use of FDA approved anesthesia viral filters to create a Sealed Compliant Volume PAPR. [ … ] Bunny Science Science™ PAPR isolates user via positive pressure instead of requiring a perfect face to mask seal. [ … ] Bunny Science Science™ PAPR extends use of approved, viral filters. These are ubiquitous in the operating room setting and provide N99 filtering for patients. [ … ] Design Highlights [ … ] * Filters air via FDA approved, ventilator viral filter or medical air/oxygen * Covers entire head and face against * Use positive pressure to maintain isolation * Dramatically lower airflow requirements * Use disposables that are readily available [ … ] Developmental Testing [ … ] The Bunny PAPR has been tested at my hospital against nebulized N95 test aerosols for proper isolation. To simulate worst case test conditions, test aerosol was directed at air intake, exhausts, and neck seal. Although, this is not identical to NaCl challenge, there is no logical reason to require re-testing of filters already accepted by FDA as having 99.99% viral filtering. [ … ] Physiologic monitoring for CO2 clearance, oxygen saturation, and respiratory rate was verified as sustainable using OR patient monitor and continuous gas sampling analysis. User ability to wear system for 11 hours was confirmed. Wearer has ability to carry out typical operating room procedures, intubate, extubate, monitor, fill out EHR, walk and push gurneys.
