CLMMRH, PhilippinesTitle: A – Aegis Mark II S – Study on P – Powered Air P – Purifying I – Innovation R – Respirator E – Efficiency: ASPIRE
Abstract
Introduction: The COVID-19 pandemic has caused approximately 7 million mortalities worldwide and evidence suggests that it is transmitted through respiratory droplets resulting to shortages of Personal Protective Equipment (PPEs) needed for prompt patient care. This study was done to assess the locally developed Aegis Mark II Powered Air Purifying Respirator (PAPR).
Methodology: This laboratory controlled non-interventional testing included: battery and usable power; mechanical construct of hood and blower unit; user acceptance through a clinical simulation that included the training and education, clinical performance, communication, comfort and PAPR care; and filtration efficacy using NaCl particulate.
Results: The Aegis Mark II PAPR has a 20,000mAh rechargeable Lithium battery pack with a mean usable time of 11:34, (Std. dev.: 0:16 (H/M)), and 8:34, (Std. dev.: 0:38 (H/M)), for low and high flow blower settings, respectively. The mean charging time of 2:20, (Std. dev.: 0:19 (H/M)), using a Fast Cellphone Charger (2.4 Amps). It had significantly better survey responses compared to the commercial PAPR. The mean particle counts inside the hood of the Aegis Mark II PAPR and Commercial PAPR showed that PM2.5 (5.7 and 6.2), and PM10 (6.2 and 6.6) values were within acceptable Ambient Air Quality Standards.
Conclusion: The Aegis Mark II PAPR battery power supply is adequate and showed significantly better survey scores compared with the commercial PAPR and the filtration efficacy was comparable with the commercial PAPR. It can provide a high degree of protection and will alleviate the logistical strain during pandemics and public health emergency.
