Advances in respiratory protective equipment: practical experiences of CleanSpace® HALO™ by healthcare workers

Personal protective equipment (PPE) offers protection from infections and hazardous materials. Advances in technology have seen rapid improvement of respiratory PPEs but real-world evaluations are needed to understand whether newer devices offer greater usability and overcome common barriers to correct use.

To survey the user experiences of a new PPE device, CleanSpace® HALO™, in comparison to existing masks and respirators to determine advantages and disadvantages.

Frontline healthcare workers of a large healthcare provider cluster in Singapore with practical experience of using respiratory PPE, including the CleanSpace® HALO™, were surveyed. Ease of communication, comfort, usability, ability to provide care, perceived effectiveness, barriers, and enablers to respiratory PPE use were investigated.

A total of 93 respondents were included in the analysis. CleanSpace® HALO™ was rated highly in terms of perceived safety (92%), comfort (40%), and ease of donning and doffing (53%). CleanSpace® HALO™ was less disruptive to patient care (8%), although the ability to communicate effectively remained an obstacle (22%). Respondents also noted the incomplete facial protection provided by CleanSpace® HALO™.

Respiratory protective devices are integral to effective infection control protocols, but their usefulness is limited by their impact on care delivery and incorrect use. The CleanSpace® HALO™ demonstrated advantages over existing powered air purifying respirator devices but some issues remain. Future iterations must strive to overcome communication challenges and address common side-effects. Better education is also needed to improve user confidence with CleanSpace® HALO™.
