COVID-19 Airway Management Isolation Chamber.

ABSTRACT:

Objective

During the coronavirus pandemic (COVID-19), health care workers are innovating patient care and safety measures. Unfortunately, many of these are not properly tested for efficacy. The objective of this study was to determine the efficacy of the novel COVID-19 Airway Management Isolation Chamber (CAMIC) to contain and evacuate particulate.

Study design

Multi-institutional proof-of-concept study.

Setting

Two academic institutions: Walter Reed National Military Medical Center (WRNMMC) and Madigan Army Medical Center (MAMC).

Subjects and methods

Smoke, saline nebulizer, and simulated working port models were developed to assess the efficacy of the CAMIC to contain and remove ultrafine particles. Particulate counts were collected at set time intervals inside and outside the system.

Results

With the CAMIC on, smoke particulate counts inside the chamber significantly decreased over time: r(18) = -0.88, P < .001, WRNMMC; r(18) = -0.91, P < .001, MAMC. Similarly, saline nebulizer particulate counts inside the chamber significantly decreased over time: r(23) = -0.82, P < .001, WRNMMC; r(23) = -0.70, P < .001, MAMC. In the working port model, particulate counts inside the chamber significantly decreased over time: r(23) = -0.95, P < .001, WRNMMC; r(23) = -0.85, P < .001, MAMC. No significant leak was detected in the smoke, saline nebulizer, or working port model when the CAMIC was turned on.

Conclusions

The CAMIC system appears to provide a barrier that actively removes particles from within the chamber and limits egress. Further studies are necessary to determine clinical applicability. The CAMIC may serve as an adjunct to improve health care worker safety and patient outcomes.

Project description:The whole world at present is dealing with the COVID 19 pandemic. As per studies worldwide SARS-CoV-2 by sequencing analysis is 95% homogenous similar to the bat coronavirus and almost 70% similar to the SARS-CoV-1. SARS CoV 2 is a respiratory problem which in its worst form of disease causes ARDS and hampers the patient's ability to breathe on his own and has to be put on Ventilator. As per WHO (World Health Organization) guidelines, sanitization is an effective way of prevention from the infection. The proper sanitization being not feasible and time consuming in certain cases, faster and effective alternatives of sanitization processes are necessary. As per recently published study by researchers in Beijing, China, it was observed that with each degree rise in temperature and percent humidity, the contagiousness of the disease caused by the Coronavirus, named COVID 19 goes down significantly. R-naught or RO can be referred as the average number of people that gets infected from one sick person among a population which is not immune to the virus. The closer to zero an RO value the better the results indicating less spread of the disease. A lower RO means the outbreak is slowing or declining while a higher one means its swelling or growing at faster rate. The RO of the coronavirus hovers between 2 and 2.5 as per World Health Organization or WHO meaning that each new person spreads the disease to about 2.2 people on an average. The chamber being developed is aimed at lowering the Ro value so that the infection rate slows down. RO is not a fixed value, it changes depending on various factors such as proximity among people, the environmental surroundings and climatic conditions. The higher temperatures (38 °C) at 80-90% relative humidity decreases the virus activity within 24 h. Moreover, in a condition where the virus that was dried was stored at higher temperature (>38 °C) and high relative humidity (>95%), there was observed an additional degradation in virus activity at each point in time. Taking into consideration the above research, we developed a COVID De-Incubator chamber to disinfect the clothes and commonly used daily wear items. Our results were exciting as the disinfection proved to be effective at temperatures of 75 °C-80 °C and humidity levels at 80%-90%. Moreover, the chamber was developed at significantly lower costs. In this study, an attempt has been made to fabricate a chamber with temperature and humidity-controlled environment to disinfect daily used material. Using fins and momentum source, a homogenous environment is created inside the chamber for better results, with the help of numerical simulation to decide the optimum angle for the inclination of fins and location of the momentum source.
