Study of ICU patient condition alert generation process using D2D under LTE network

An ICU patient is vulnerable at any moment and requires constant monitoring and fast response from the doctors and nurses at critical moments. To do so, the doctors and nurses must know when the critical situation arises to attend the patient right on time. In this paper, we propose a heterogeneous network merged with an automated system to generate alert signal if the patient is in critical condition and pass the alert mode to the nurses and doctor for fast response from them. Another issue is to inform the patient´s worried visitor/attendant waiting at the hospital by sending a report periodically with selective data stating his condition. Since D2D communication under LTE network works well in close proximity, we can deploy this technique to alert the doctor about his patient´s critical condition and also to transfer the report of the ICU patient´s attendants waiting outside or nearby. Simulations showed that the time required for transmitting alert signal to the doctors is only few seconds indicating critical condition of the patient. This proposal needs 4G LTE network enabled smart phones as it uses D2D communication from server point to nurse station, doctor and patient attendants. Still, employing D2D will be very cost effective as we emphasis on saving human lives in time.
