A Patient Risk Minimization Model For Post-Disaster Medical Delivery Using Unmanned Aircraft Systems, Mark J. Simpson

Doctoral Dissertations and Master's Theses

The purpose of this research was to develop a novel routing model for delivery of medical supplies using unmanned aircraft systems, improving existing vehicle routing models by using patient risk as the primary minimization variable.

The vehicle routing problem is a subset of operational research that utilizes mathematical models to identify the most efficient route between sets of points. Routing studies using unmanned aircraft systems frequently minimize time, distance, or cost as the primary objective and are powerful decision-making tools for routine delivery operations. However, the fields of emergency triage and disaster response are focused on identifying patient injury severity …

Modelling Air Quality In An Aircraft Passenger Cabin Using Health Care Standards, Bert Silich

International Journal of Aviation, Aeronautics, and Aerospace

The interest in aerosol contamination of aircraft passenger cabins has increased since the onset of the COVID-19 pandemic. Mathematical models have been developed to help describe how an aerosol behaves in a closed space. The number of infectious particles inhaled is of scientific interest because it can be related to the risk of getting ill from a pathogen. The data required to calculate these results is often difficult to obtain in real world settings. In fact, particle inhalation details are not obtained in the day-to-day routine of a health care environment and are they not required to maintain safety. Hospital …

Engineering Controls For Bioaerosols In Non-Industrial/Non-Healthcare Settings, David Krause, Cheri Marcham, Bill Mele, Jack Springston, Rob Strode, Donald Weekes, Neil J. Zimmerman

Publications

The list of disease pathogens that can be transmitted in the air is extensive. This list includes the common cold, SARS, measles, Hansen’s disease (leprosy), polio, influenza, Legionella (Legionnaires’ disease and Pontiac fever), and tuberculosis (TB). TB, SARS-CoV-1, avian influenza, varicella, and now SARS-CoV-2 all have received public notice due not only to their known or assumed ability to be transmitted in the air rapidly from one individual to another, but also for their virulence. Other bioaerosols that can be transmitted through the air include bacteria, fungal spores and fragments, dust mites, and pollen. This document was developed to address …

A Model For Inhalation Of Infectious Aerosol Contaminants In An Aircraft Passenger Cabin, Bert A. Silich

International Journal of Aviation, Aeronautics, and Aerospace

Aerosol contamination of an aircraft cabin by infectious passengers is a concern of passengers, aircrew and the aviation industry. This may be especially important during a pandemic, such as COVID-19, where the full extent of aerosol transmission is not well understood. A statistical method to determine the number of infectious passengers on board along with a mathematical model estimating the contaminant concentration of aerosols in the cabin and the number of inhaled infectious particles by passengers is presented. An example is used to demonstrated how the results can be estimated during normal operations and emergency conditions with malfunctions of the …

Face Mask Effects Of Co2, Heart Rate, Respiration Rate, And Oxygen Saturation On Instructor Pilots, Andrew R. Dattel, Nicola M. O'Toole, Guillermina Lopez, Kenneth P. Byrnes

Publications

The COVID-19 pandemic has required people to take new measures to mitigate the spread of the communicable virus. Guidelines from health organizations, government offices, and universities have been disseminated. Adherence to these guidelines cannot be more critical for flight training. This study explored the effects face masks had on CO2, heart rate, respiration rate, and oxygen saturation while wearing a face mask at an oxygen level simulated to 5,000 feet. Thirty-two instructor pilots (IP) volunteered to participate in the study. IPs spent 90 minutes in a normobaric chamber while wearing a cloth face mask or a paper face mask. Participants …

Integrating Aviation Technology, Emergency Services, And Human Resilience: Considerations From Social Scientists, Chelsea A. Lenoble Ph.D., Joel M. Billings Ph.D., Allison A. Kwesell Ph.D., Ray H. Chang Ph.D.

National Training Aircraft Symposium (NTAS)

Unmanned aerial systems (UAS) have a range of applications within the field of disaster response. This presentation offers a novel framework of psychosocial considerations designed to advance UAS and disaster management integration. Social scientists highlight important challenges to the effective integration of three primary entities: UAS, the team of teams that responds to disasters, and populations affected by disasters.

The presentation adopts an emerging theoretical perspective on the intersection between UAS capabilities and disaster phases and extends it by bringing necessary attention to social science issues. Specifically, the framework outlines psychosocial considerations and areas of improvement for preparation (training), response …

Surgical And Medical Applications Of Drones: A Comprehensive Review, Brent Terwilliger, James C. Rosser Jr., Vudatha Vignesh, Brett C. Parker

Publications

Drones have the ability to gather real time data cost effectively, to deliver payloads and have initiated the rapid evolution of many industrial, commercial, and recreational applications. Unfortunately, there has been a slower expansion in the field of medicine. This article provides a comprehensive review of current and future drone applications in medicine, in hopes of empowering and inspiring more aggressive investigation.

Background: Drones have the ability to gather real time data cost effectively, to deliver payloads and have initiated the rapid evolution of many industrial, commercial, and recreational applications. Unfortunately, there has been a slower expansion in the field of medicine. This article provides a comprehensive review of current and future drone applications in medicine, in hopes of empowering and inspiring more aggressive investigation. Database: A literature search was performed by EBSCO (Elton B. Stephens Company) Discovery Service, searching the phrases "drones," "UAV," "unmanned aerial vehicles," "UAS," and "unmanned aerial systems." A second search was used to identify sources that contained …

General Aviation Hypoxia And Reporting Statistics, Timothy B. Holt, Jacqueline Luedtke, Claire Schindler

Publications

“All too often, pilots tell me they don't need physiological training because they don't fly that high. The statement points out the general feelings of a large majority of the aviation population. I suppose then the burning question is ‘why do we still have aircraft accidents?’” (Boshers, 2015). To this day there are no statistics on how often general aviation pilots experience hypoxia during everyday operations. General aviation pilots (i.e. non-commercial operations) were chosen for this study because:

• Little regulation regarding flight physiology training
• General attitude of invulnerability towards hypoxia
• No requirement to report hypoxia or similar events

Design And Commissioning Of A Community Scale Solar Powered Membrane-Based Water Purification System In Haiti, Shavin Pinto, Yung Wong, Kyle Fennesy, Yan Tang, Marc Compere

Publications

This paper presents the design and commissioning of a solar powered water purification system at the Ryan Epps Home for Children (REHC) in Michaud, Haiti. This system supplies clean drinking water to the 200 children who live and go to school at REHC and also to the community in the form of a micro-business. This micro-business is the mechanism for income generation for sustainable system operation. The purifier uses a three stage filtration system with a disc-type sediment filter, a 0.1 micron ultrafiltration membrane, and an ultraviolet light for disinfection. The backwash cycle extends the life of the ultrafiltration membrane …
