One such example is smart wrist-watch based sensors.įor the patients of accidents and sudden injuries, the time they are monitored remotely could be only the time they are being transferred to the hospital in an ambulance. Even if there are wearable sensors, these pose minimum effect to the activities. So, these applications support activities like sitting, standing, using the bathroom, watching television, reading and sleeping, with least inconvenience to the user. With the new remote health monitoring applications, elderly patients can engage in daily activities without support from a caretaker. Therefore, whole systems are being built to support this concept with the use of different technologies. Most research follow the policy of allowing the mobility and activity freedom at home or personal environments which are beneficial for the patients rather than being confined into a high-cost hospital room. The aim of good healthcare is the ability to support ordinary life as much comfortable as possible to all patients. All these types of patients have conditions that are better to be monitored continuously. Remote monitoring of patients target several sub-groups of patients, such as patients diagnosed with chronic illnesses, patients with mobility issues, or other disability, post-surgery patients, neonates and elderly patients. The advantages of remote monitoring of patients are: early and real-time detection of illnesses, ability to continuously monitor patients, prevention of worsening of illnesses and untimely deaths, cost reduction in hospitalizations, reduce the number of hospitalizations, obtain more accurate readings while permitting usual daily activities for patients, improve efficiency in healthcare services by utilizing communication technology, emergency medical care, service for patients with mobility issues, emergency care for traffic accidents and other injuries and usage of non-invasive medical interventions. telehealth, mobile health) all of which mean monitoring of patients outside hospital conditions by the means of technology. Remote healthcare has many categories, (e.g.

Remote healthcare is an emerging research field as the world moves towards remote monitoring, real-time and fast detection of illnesses. The paper also includes some directions for future research. With the review, the authors discuss some issues available in most systems. This study provides a review of the recent advances in remote healthcare and monitoring in both with-contact and contactless methods.

Fall detection systems and applications to monitor chronical ill patients have already become familiar to many. The technology varies from sensors attached to body to ambient sensors attached to the environment and new breakthroughs show contactless monitoring which requires only the patient to be present within a few meters from the sensor. These new technologies can monitor patients based on the illness or based on the situation. Range of remote healthcare varies from monitoring chronically ill patients, elders, premature children to victims of accidents.

Sensors for monitoring essential vital signs such as electrocardiogram reading, heart rate, respiration rate, blood pressure, temperature, blood glucose levels and neural system activity are available today. With relatively simple applications to monitor patients inside hospital rooms, the technology has developed to the extent that the patient can be allowed normal daily activities at home while still being monitored with the use of modern communication and sensor technologies. A recent development in this area is remote monitoring of patients which has many advantages in a fast aging world population with increasing health complications.

Healthcare is a field that is rapidly developing in technology and services.
