Introduction
Emergency responders need massive amounts of information to guide their decision-making when a crisis threatens lives and livelihoods. The decision-makers take the information promptly and with sufficient precision to accurately appraise the situation. Visual pictures and other remotely sensed data are critical for response preparation because they provide a fast breakdown of the incident and a detailed description. In today’s worldwide environment, the frequency of accidents is rather significant, and the danger of death rises in case of delayed medical assistance (Baumgarten et al., 2021). Thus, it is essential to deploy a drone ambulance to expedite this process due to poor road conditions and traffic congestion since it will follow a much quicker path than the roadways.
Currently, drones can only carry a single kind of medical help, such as a defibrillator. Within minutes of an abrupt cardiac arrest, administering defibrillation may save a life (Baumgarten et al., 2021). Despite massive spending and the difficulties in the Public Access Defibration (PAD) systems, healthcare can still deliver this for most people through Emergency Medical Services (EMS) (Baumgarten et al., 2021). This article explores the medical uses of drones equipped with Unmanned Aircraft Systems (UAS). UAS has a minimal operating cost that can quickly deliver defibrillators to the victim, regardless of the victim’s geographic location, provide visual feedback and situational information to the Emergency Medical Services (EMS) dispatcher, and aid a bystander in giving better cardiopulmonary resuscitation (CPR) (Baumgarten et al., 2021). Although there are several real-world impediments to practical implementation, all these impediments will be overcome as technology advances.
Details of the UAS application and the data collected
Drones’ ability to collect real-time data and deliver payloads cost-efficiently has accelerated the emergence of a wide variety of industrial, commercial, and recreational uses. For instance, drones monitor disaster sites and places with biological dangers and epidemiology research and disease monitoring (Rakha & Gorodetsky, 2018). Telemedicine drones can diagnose, offer treatment, perioperative assessment, and telemonitoring in distant places. Similarly, telemedicine drones can carry microbiological and laboratory samples, medications, vaccinations, and emergency medical equipment of the patients (Van de Voorde et al., 2017). Government agencies have elevated the use of drones to a national priority. The following phases include vigorous safety research, industry development, enhanced public awareness, and engagement (Rakha & Gorodetsky, 2018). These applications present opportunities for effective remote procedures in the medical field.
Importance of the data/deliverables
Drones have several significant applications in diagnostics. For instance, they improve access to and the speed of delivery of life-saving drugs and vaccinations (Laksham, 2019). Similarly, specific diagnostic tests are time and temperature-sensitive, and it is crucial to deliver to the laboratory after obtaining a patient’s sample. As a result, the medical community must transfer drugs, laboratory tests, diagnostics, blood, and tiny medical gadgets efficiently from point one point to another (Laksham, 2019). All this illustrates the importance of a drone’s ability to fly quickly and far and carry a substantial payload enables it to overcome the time constraints associated with performing a diagnostic test.
Current Methods of Obtaining Data Deliverables
Today, patients, healthcare locations, and EMS systems gain from helicopter emergency medical services (HEMS) and Ground emergency medical services (GEMS). The most crucial outcomes demonstrate prospective patient benefits, such as functional survival and pain alleviation (Pham et al., 2017). Compared to Ground Ambulances, HEMS teams have pharmacologic and procedural capabilities that allow them to provide a higher quality of treatment at a trauma scene or a small referring hospital.
Strengths and Weaknesses of UAS applications
Strengths
A key advantage of drone deployment is the possibility of reducing travel time for diagnosis and treatment. A drone may reach patients ten times quicker than regular emergency responders (Laksham, 2019). Drones are an expensive alternative to vehicle transport in rugged terrain. According to a computer model, drones can increase vaccination availability while decreasing costs (Laksham, 2019). By flying near the Earth’s surface, drones circumvent the limitations of satellite images, such as cloud contamination, and can provide reliable data. Drones have supported rescue teams in locating and photographing operations under challenging areas like mountains, valleys, and winter weather terrain (Laksham, 2019). Despite all these strengths, there are still some weaknesses in using drones.
Weaknesses
Drones are subject to several regulations in terms of public health. Consider the labor and the infrastructure. Drone operations need trained operators and continuous on-the-ground supervision (Laksham, 2019). Another possible concern is a lack of infrastructure, such as a runway. When using drones for medical reasons, individuals who now deliver medical supplies may lose their employment even though operating the drones may need additional workers.
Technical Restriction is a related notion. Unlike commercial aircraft and helicopters, drones cannot deliver large cargo over long distances because of a smaller payload capacity. The more sophisticated a drone develops, the heavier and more costly it becomes (Laksham, 2019). Similarly, the safety and effectiveness of drones are not entirely known. For instance, biological samples are sensitive and need careful packing to prevent tampering during shipment (Laksham, 2019). When carrying drugs or vaccines, drones must have ice packs or coolers to stop the drugs from going bad. The tolerance of drones to adverse environmental conditions like wind and turbulence is unclear, and electromagnetic interference has hindered signal reception in drones’ ground-based monitoring (Laksham, 2019). These are some of the limitations of drone UAS applications as drone ambulances.
Detailed Mission Operations and Requirements
Public Health and Medical Surveillance
Drones can monitor disaster zones, including biological or chemical hazards, and identify disease spread. For instance, drones can compile information on the number of patients needing care and prioritize those with high-risk diseases (Rosser et al., 2018). Drones are advantageous for epidemiological research because they can record high-resolution temporal and geographic data in real-time. Hence, to keep an eye out for possible emergency patients, this operation will need monitoring for deforestation, agricultural development, and other activities that affect natural ecosystems and biological populations (Rosser et al., 2018). Additionally, drone technology can discover potential health hazards such as heavy metals, pollution, and radiation (Rosser et al., 2018). For example, researchers used drones equipped with high-resolution photogrammetry software in southern Italy to accurately analyze and estimate cancer risk related to higher copper concentrations in agricultural districts (Rosser et al., 2018). This detection will require the employment of drones equipped with an integrated sampling platform capable of accurately monitoring aerosol and trace gas concentrations in rugged terrain.
Telemedicine
Telemedicine is the practice of diagnosing and treating patients remotely via communications technologies. It involves drones that require establishing a cellular communications system between the doctor and the robot to conduct telesurgery (Rosser et al., 2018). The telesurgery will include working surgical techniques with the assistance of a robot, with the technician operating from a remote location away from the patient. This surgery will require a telemedical drone that will transfer medical supplies and communication packets to make the procedure possible in an emergency clinical circumstance.
Medical Transport
Drones are an intriguing medical delivery platform because of their rapid reaction times and ability to penetrate otherwise impenetrable terrain. Transporting microbiological specimens from outpatient settings to National Health Location facilities for speedy HIV testing will need compact coolers to ensure that the material arrives at the hospital in excellent condition for screening (Rosser et al., 2018). Similarly, it has been crucial to use drones in emergency care to carry automated external defibrillators (AEDs) to people experiencing cardiac arrest (Rosser et al., 2018). There is a need for correctly stationed drones and fewer airspace rules for this distribution to be efficient.
Client Data Needed, and the UAS platform Required to Capture data
Every day, medical professionals and third-world humanitarian workers encounter many obstacles. Drones enable remote regions to get blood, vaccinations, birth control, and snakebite serum, among other medical supplies (Sigala & Langhals, 2020). They may transfer medication inside hospitals, move blood between buildings, and assist seniors aging in place. However, none of this is feasible without using mobile applications to accomplish this goal without information interchange. Location, age, the nature of the client’s illness, medical history, and a feeling of urgency are only a few pieces of information necessary to carry out the surgeries (Sigala & Langhals, 2020). Smartphones are capable of data collection. Fixed-wing aircraft are an excellent platform for conducting operations since, in comparison to other platforms, they typically have flying periods of 45 to 90 minutes or nearly double the length of rotorcraft (Sigala & Langhals, 2020). Fixed-wing aircraft travel a greater distance in a single flight, making it the best UAS platform to capture data.
Output and Resolution of Data Needed
With the growing significance of unmanned aircraft systems (UAS) in data gathering for medical investigations, two critical issues are harmonizing and standardizing data collecting instructions and developing procedures adaptable to a wide variety of circumstances. For example, gathering high-ground spectral resolution data in Public Access Defibrillation programs and long-range surgical procedures ensures that the EMS and physicians know what is occurring on the ground and can respond appropriately (Singh & Frazier, 2018). As a result of the evolving nature of this technology, the optimum reaction requires high-quality pictures and data. To send and record reliable quality data, drones should use defined processes, radiometric and atmospheric correction, sensor calibration and error characterization, or even a classification accuracy evaluation.
Safety Concerns and the correct type of drone to use
Numerous groups are now engaged in a comprehensive effort in the United States and globally to develop legislation permitting the safe operating of UAS in the medical field. Federal laws controlling unmanned aircraft are currently restricted in scope, and their absence impedes realizing the full potential advantage of UAS operations (Fang et al., 2018). When integrating UAS operations into the medical field, it will be critical to evaluate the ramifications of varying degrees of vehicle control and autonomous capabilities and the system’s source of traffic observation. The projected degree of protection varies according to vehicle features and population density in the case of ground impact hazards and traffic density in the case of airborne accidents.
The best drones for the job vary in terms of safety. Safety measures indicate that it may be feasible to fly tiny UAS over the bulk of the United States with minimal operating and size constraints (Fang et al., 2018). As the mass of UAS rises, mitigating measures must be implemented to limit further the danger of ground contact and midair collision to the FAA-recommended standards. It is in the public interest to maximize the advantages of UAS operations in the medical field while maintaining safety via effective risk reduction with the fewest limitations feasible.
When UAS Application will be put into Use
Many of the constraints on drone operations have been lifted by technological improvement. Drones are a good option in various ways due to their effectiveness, accessibility, and durability. Local governments are becoming more comfortable with drones in their simple search and rescue missions (Olsen, 2017). Authorities are collaborating to devise a solution using drones. Drones may also be used with thermal imaging to locate missing humans, such as when an Amber Alert is issued for a missing kid. Due to such advancements and the growing need for swift application services, especially in the medical area, it is only a matter of time until the application becomes routinely used (Olsen, 2017). Once the rules necessary to safeguard the safety of residents are in place, the UAS applications will be ready for usage.
Airworthiness considerations
Air traffic safety is the primary issue owing to the possibility of public injury. Drones cannot fly over-regulated airspace or dense crowds of people in most cases. The FAA issued two new safety guidelines governing drone operations to improve aviation safety and foster potential commercial uses (Olsen, 2017). By categorizing drones based on their registration, further information on the kinds and sizes of drones on the market will be gathered. Magnetic interferences may be more prevalent in North/South Poles places. Additionally, targeted radio or cellphone jamming might disrupt flying frequencies. Operators may be required to establish encrypted channels specifically for urban operations. Safe flying zones might be set to prevent drones from flying in random areas for recreational reasons (Olsen, 2017). Due to these factors, drones may transfer medications from pharmacies to nursing homes.
Sensor Selection and Why
An Inertial Measurement Unit is a sensor used (IMU). The IMUs aggregate data from several sensors to provide results that may be used to determine the direction, altitude altimeter, and speed of the UAS (Chen et al., 2017). It is equipped with Gyroscopes, which help detect the vehicle’s rotation rate, angular momentum, and tilt when carrying medical services. It has accelerometers that detect linear movement along any axis, ensuring the drone’s speed. As a result, it will get to its destination swiftly and safely (Chen et al., 2017). Finally, it includes magnetometers that detect and signal the direction of the magnetic field to confirm heading and prevent magnetic interruptions while carrying a valuable specimen or responding to an emergency.
Processing and Analytical System Selection
UAS, often known as drones, are unmanned aerial devices capable of surveying large regions and reaching human-hostile locations. The process to follow when processing and analyzing to select UAS systems include the following: remotely piloted or autonomously controlled systems, sizes ranging from centimeters to tens of meters, weights ranging from tens of grams to thousands of kilograms, and operational altitudes ranging from tens of meters to thirty kilometers (Chen et al., 2017). Similarly , it is critical to remember that UAs-related technology constantly evolves when selecting processing and analytical systems. The number of UA-related applications is growing exponentially (Chen et al., 2017). These applications include real-time monitoring, wireless coverage, remote sensing, search and rescue, package delivery, security and surveillance, precision agriculture, and civil infrastructure inspection.
Systems Required and Why
Rotor wing unmanned aerial systems are optimal since they are a kind of aerial vehicle with widespread adoption and generating rising attention among academics. Rotor Wings are capable of vertical landing and take-off and are often used in quadcopters; their diminutive size makes them simpler to manage.
Crew Personnel Required
Drones are piloted using remote ground control systems (GSCs), often known as ground cockpits. A method for uncrewed aerial vehicles comprises two components: the drone and the control system (Olsen, 2017). All sensors and navigational devices are located in the nose of the uncrewed aerial vehicle. Prospective remote pilots must undergo Part 107 training or an equivalent program produced under an authorization certificate to fly a drone commercially (Olsen, 2017). The objective is to ensure the continued safety and success of activities. Thus, crew members flying UAS ambulance drones must be educated and equipped similarly to commercial pilots and adhere to all FAA requirements.
Skills and Experience of UAS drone Pilots
A commercial drone pilot must be meticulous, socially confident, and organized to operate a UAS safely and effectively. A competent drone pilot follows all applicable laws and regulations and takes the time to examine the ramifications of their actions. They must arrive early enough on-site to do a comprehensive site and weather assessment, explore the area, identify risks, and test their equipment (Pham et al., 2017). A good pilot will recognize the possibility of mishaps and not exaggerate their talents but will still be confident enough to complete a mission successfully. Effective drone pilots are data collection machines! They inquire about obtaining a better understanding of a situation. A pilot who takes the time to prepare and acquire information significantly increases the likelihood of executing safe and successful flights. Commercial drone pilots must be aware of their role as Pilot in Command (PIC). The PIC is ultimately responsible for all choices made by themselves or their team (Pham et al., 2017). Drone pilots must make sound Go/No-Go decisions and understand when to impose flying restrictions or limits.
Regulatory Considerations
Given the regulatory difficulties inherent in the growing field of counter-UAS and detection capabilities, enterprises confront a challenging challenge in evaluating, procuring, and deploying such equipment. By avoiding the deployment of counter-UAS equipment that actively mitigates UAS flight through RF broadcasts, airport operations may be impacted, such as navigation beacons or airport communications infrastructure (Olsen, 2017). Each business must understand its unique UAS danger profile and develop customized UAS risk management plans. The strategic and operational concerns are exacerbated by the legal and regulatory issues that mission leaders must address. Currently, only the Departments of Defense (DoD), Energy (DOE), Justice (DOJ), and Homeland Security (DHS) are authorized to conduct UAS signal analysis and mitigation efforts (Olsen, 2017). The DOJ is responsible for enforcing the United States criminal code sections that pertain to systems that detect UAS. Entities contemplating integrating drone security solutions into their infrastructure should have these regulatory issues in mind.
Conclusion
Drone use for medical purposes has several benefits, including providing immediate assistance, reducing travel time to the patient, reducing complications in the injured due to a short wait for rescue, assisting and improving basic operations of medical emergency teams, and the ability to reach areas inaccessible to conventional modes of medical transport.
However, it is critical to be informed of current restrictions. There are several safety awareness programs, but neither they nor the most flawless rules can guard against hazards posed by the presence of a drone in an area it was not designed for. The arrival of unidentified aircraft in a regulated environment is a concern that has been highlighted as a threat to aviation safety on a global scale. Examples include recording a vast passenger aircraft nearby or interfering with an international airport’s arrival due to a drone’s identification.
