With the increasing world population, the need for health prevention is also increasing. In these recent years, there is a rapid advancement in clinical care due to the technological advancements in the various fields of sensors, micro-controllers, and computers for assuring fast recovery of patients in the hospitals. The major and crucial necessity of the hospitalized patients is that each patient ought to be provided with a better treatment and observation and ought to be provided the right measure of vital nutrition at the right time. Whenever a saline is fed to the patients, the patient needs to be persistently administered by a nurse or a care-taker. There are many cases where patients are being harmed due to the staff inattentiveness, as their absence does not notice the completion of saline level in the container. This arises the problem of back flow of blood immediately after the completion of saline in container. By developing this system, it can overcome the risk of air embolism, electrolyte imbalance, etc. An air embolism occurs when air bubbles enter a vein or artery and block the flow of blood. This can be a serious and potentially life-threatening condition. an IoT based saline Alert system was developed in order to protect the patient and to provide them with safety during saline feeding hours. The primary objective of the project is to develop a state-of-the-art system for real-time Saline Alert System using a blend of Arduino UNO, sensors and C programming.
