While telemedicine refers specifically to remote clinical services, telehealth can refer to remote non-clinical services, such as provider training, administrative meetings, and continuing medical education, in addition to clinical services.
Telehealth is a subset of E-Health, which includes the delivery of health information, for health professionals and health consumers, education and training of health workers and health systems management through the internet and telecommunications.
Telemedicine involves the use of electronic communications and software to provide clinical services to patients without an in-person visit. Telemedicine technology is frequently used for follow-up visits, management of chronic conditions, medication management, specialist consultation and a host of other clinical services that can be provided remotely via secure video and audio connections. In short, all telemedicine is telehealth, but not all telehealth is telemedicine.

Suing operations were performed on a phantom in simulated zero gravity environment to measure the capabilities of surgeons controlling the robots from Seattle. This time the Aquarius was connected to the mainland through a Spectra 5. A group of three professionals guided the robot using commercial internet connection, and the communication lag time was increased till up to 1 s. The M7 demonstrated the first image-guided autonomous surgery using a portable ultra sound system.
The M7 was able to insert the needle into a tissue phantom by itself. To facilitate exploration missions beyond Earth, space agencies have always been pushing for more advanced telehealth concepts.
Surgical experiments laparotomy and celiotomy on rabbits were first reported from Russian cosmonauts in The first survival procedure was performed on STS Neurolab mission on rats in Campbell el al.
ESA had plans to perform teleoperation in with a robot controlled through satellite connection, but the mission was postponed. On a DC-9 hyperbolic aircraft suturing tasks were performed with the M7 Figure 7.
The performance of classical and teleoperated robotic knob tying was measured. Both the master and the slave devices were equipped with acceleration compensators, otherwise it would have been almost impossible to succeed with the tasks. The results showed that humans can still better adapt to extreme environments, however, advanced robotic solutions do not fall far behind. The M7 on board of a NASA parabolic flight, and the robot performing autonomous ultrasound-guided tissue biopsy.
Effectiveness of surgical care heavily relies on the prompt delivery of treatment, and extreme teleoperation serves this principle. Beyond the obvious challenges of reduced medical equipment, constrained resources and probably limited experience of the on-site staff, several technical difficulties arise with extreme telesurgery.
Significant delay in the sensor feedback can totally distract the surgeon and cause serious safety hazard, as examined by different research groups. Engineering methods have been developed to overcome the difficulties originating from the absence of communication infrastructure, unpredictable propagation condition changes and hardware failures. Robotics roadmap points to robotic telesurgery as a major focus of research in order to improve quality of care Christensen et al.
It calls for engineering solutions to ensure natural interaction between the human operator and the remote robot through specific patient models, from whole-body level to tissue characteristics. This would allow for advanced off-site surgical planning, automated guidance and also for realistic training opportunity. The primary difficulty with teleoperation over large distances or low quality network infrastructure is the communication lag time.
The continuous development of the internet backbone infrastructure has resulted in a significant reduction of typical delays. Using commercial services, delay may be around 85 ms, across the United States, and lag time might be anywhere from ms world-wide.
Typical roundtrip delays are 40 ms, but the bandwidth is only 64 kbps per channel. Currently developing O3b Networks scheduled for deployment late would provide 1 Gbps with approximately ms lag time.
Geosynchronous satellites provide higher latency due to their 36, km altitude above the equator. Round trip latency is ms typically. Understandably, designated military satellites can provide a lot faster communication channel, the minimum latency per satellite hop is expected to be 4. Despite the recent improvement in surface line speed, satellite communication has the potential to overcome ground lines primarily in speed, with a reasonable quality of service and availability.
Beyond Earth orbit radio and microwave frequency signals propagate at almost the speed of light in space, however already in the range of long distance manned space missions, several minutes of latency can be experienced. Planet Mars orbits 56,, km to ,, km from Earth which means a 6. In addition, for about two weeks every synodic period, direct communication can be blocked, as the Sun stays in between Earth and Mars, direct.
Most humans are capable of adapting to sensory feedback latency up ms Anvari, and some experiments suggest that individuals might be able to perform tasks even with a consistent ms delay Lum et al. It is advisable to use the consistent, maximum latency of system to achieve performance continuity. However, in extreme cases this prevents the effective work and firm reaction to unexpected events.
The on-site medical assistant can also help with imminent moves and minor tasks Hanly et al. By reflecting e. The compression and decompression of the video stream can be reduced by the use of novel CODECs and state-of—the-art computing hardware, but it still takes significant time, generally ms. Approaching from the control theory point of view, several strategies have been developed to overcome the difficulties on the master side.
One solution is to realize communication delays as force reflection for the human operator Nohmi, It feels as if the remote manipulator was controlled through a virtually coupled spring, applying adequate forces. When humans are adapting to asynchronous sensory feedback, they tend to create a virtual representation of the remote site to predict the consequences of their moves and project the tools ahead.
A similar concept has been proposed for virtual reality based simulators Frank, The optimal control of the robot is calculated autonomously with high frequency on the patient site, while the Intelligent Surgical Interpreter provides an interface to the master controller.
Sensory updates are processed by the simulators at the surgeon site, and the virtual environment is updated according to the new measurements.
This framework allows the smooth integration of different modalities, but require a very precise 3D model of the patient, gained from pre-operative MRI, CT and PET scanning.
The models might be continuously updated through intra-operative imaging techniques. A variety of operations and possible outcomes could be simulated and analyzed before the actual surgery takes place, reducing the risk of complications. The concept of virtual reality extended control of surgical robots in order to locally deal with the disturbing effects of latency. Further difficulties may arise with the data protocol of the robots that links the master consol and the slave arms.
Presently, the majority of telepresence systems communicate through Transmission Control Protocol TCP that is used along with the Internet Protocol IP to send data in the form of individual units—packets. In the case of communication breakdown, the recovery time may be critical, therefore redesigned gateway architecture should be added to allow TCP transfers to survive a long duration blockage. The Zeus and the da Vinci were designed to discard each packet that has any sort of internal error; they do not correct bit-level errors.
If several packets are lost, or there is a breakdown, the robots suspend their operation. Military Standards. To ensure superior quality visual and tactile feedback, high sampling rate must be used on the patient site app. Along with the high definition video feedback this has a significant bandwidth demand. While advanced internet based communication networks enables effective telesurgery all over the Earth with the discomfort of latency , serious technological problems arise in the case of long-haul space exploration missions.
Despite the current financial difficulties, the overall goal and future direction in exploration is towards the continuous human presence on the Moon and on Mars. The presently used communication systems have serious limitations concerning the achievable minimum communication lag time, maximum bandwidth and robustness. Based on recent experiments illustrated above, we have a better understanding of the effects and drawbacks of extreme long distance telesmedicine that also apply for telementoring.
As long as a new level of machine automation is not reached, it seems inevitable to have a flight surgeon on board of the spacecraft, to adapt to any unforeseeable event.
Flight surgeons should receive special training for a better command over computer integrated surgical technology to be provided on board. The rest of the crew should also undergo comprehensive medical training to attain the skills required to monitor any surgical procedure, and to interact in the case of immediate danger.
It is also important to practice the skills with the surgery robot throughout the mission, even if no accident occurs. Based on the pre-described conditions, difficulties and system requirements, a three-layered mission architecture is proposed to achieve the highest degree of performance possible, by combining robotic and human surgery Figure 9. Depending on the physical distance between the space ship and the ground control centre, different telepresence technologies may end up with the best result.
With its uniqueness that lets expert care to be accessed by rural areas and inner cities, it is done through telecommunication like ezTalks services can be an assistance of. Especially when the patient is in a remote area, the expert can still be contacted and consulted.
It can also be installed easily on any device so anyone can use this service anytime. With the power of telecommunication like ezTalks offers, the combination of it with medical services brings telemedicine the power and benefits that it should have.
Even though the presence of an expert next to a patient can bring its healing merits, it is not possible to have expert and competent medical practitioners to be there wherever their field of expertise is needed. In addition, in the case of web conferencing and videoconferencing that reduce costs by lowering the cost of traveling, telemedicine can benefit the people that do not have the means to get the expert medical care.
Currently, telediagnostics truly provide quick hour service and save costs. An example of uses of telemedicine is a telecare to prisoners is provided as it is a challenging occurrence to either transport the inmate to a medical facility or to bring a medical expert to the prison environment.
Numerous applications of telemedicine surface today, such as teleconsultation, telecheckup, teledematology, teleradiology and telesurgery, among others.
