Serva-Vita: Prevents coding in the form of an in-hospital wireless bracelet used to notify medical personnel of the deterioration of patients’ vitals

Catalina F. Provenzano Serva-Vita Throughout the majority of hospitals around the world, cardiopulmonary arrest, or coding, is a frequent and sudden cause of death. Based off of the research of the American Heart Association, an estimated 209,000 patients, both adult and pediatric, experienced an in-hospital cardiac arrest in the year of 2012 in the United States (1). An estimated average of only 23.1% of these adult patients and 35.0% of these pediatric patients survived after the trauma had occurred, even though they were under hospital care (1). The main reason cardiopulmonary arrests have particularly low survival rates is because medical professionals are not alerted until the patient’s heart has physically stopped, where severe damage to the body, brain, and cardiac muscle has already occurred, even with resuscitation. In hospitals, nurses especially have a large number of patients to attend to and they cannot constantly monitor all of their patients during all hours of their shifts. Although cardiopulmonary arrest is a leading cause of death all across the world, there is no doubt that it is preventable because patients start showing symptoms hours before the arrest happens. Therefore, I propose the development of Serva-Vita, an in-hospital wireless bracelet that constantly monitors patient's individual respiratory rates (RR), body temperatures (T), heart rates (HR), blood oxygenation levels (SpO2), and blood pressures (BP). Designed primarily for the use of doctors and nurses, Serva-Vita notifies healthcare professionals when a patient’s vital signs drop below or exceed a range of values that is personalized for each patient. Since the bracelet is connected to a wifi network, it is synched to the individual hospitals computers, along with the hospital monitors and is therefore able to detect changes in a patient’s physical state immediately. Once one or more of these values drop below or rise above an individual’s unique vital range, the particular patient’s primary nurse is notified with a vibration and screen displaying the patient’s room number, vital sign abbreviation, and an arrow indicating whether the value has dropped or risen. Once a patient experiences a life-threatening drop in the case of, for example, cardiac arrest, every nurse present on the unit is notified when each of their bracelets vibrates and emits an alarming sound. Thus, the reaction rate is lowered dramatically and the coding patient has a better chance of receiving help in a timely manner. Because this technology will notify nurses of when their patients’ vital signs fluctuate outside of the programmed normal range, the hope is that nurses will be able to reach patients before their condition worsens and thus prevent further damage to their patient’s health. This will affect the mortality rates in hospitals globally. In the future, as populations grow, more pressure and obligations will be placed on the health care team. This device will increase the amount of time that nurses have available for their patients’ care. Serva-Vita could significantly improve survival rates as well as allow more time for the essential patient to caretaker relationship. 1. Alan S Go, MD (et al).
