Abstract :

Continuous patient vital sign monitoring is prevalent in hospitals nowadays. It helps to significantly reduce caregiverâ??s work load. Out of all the vital signs, respiratory rate is seldom continuously monitored. Nurses usually manually estimate the respiratory rate from counting within 30 seconds. This could lead to both inaccuracy and discontinuity of monitoring. Even if respiratory rate is captured in some cases, what is used in hospital nowadays is bulky and invasive devices which brings discomfort to patients. Clinically speaking, respiratory rate is equally important as compared to other vital signs. Respiration monitoring can help to predict health crises, more specifically, failures in many organ systems. Therefore, there is an emerging clinical need to provide better respiratory monitoring solution. This presentation will present an idea that provides costeffective and non-contact solution that is well-suited for patients who have a difficulty or uneasiness to use the contact RR monitoring devices. Patient's cintinously tracked RR data can be sent wirelessly to the caregivers or integrated to hospitalâ??s EMR system. Hill-Rom has in-house, developed a capacitive sensor that can be placed underneath a foam or air-filled mattress. The sensor is able to sense patient position, pressure inside the air bladders. Besides, the same sensor can be used to calculate patientâ??s respiratory rate by sensing the incremental body displacements caused by breathing. A sophisticated algorithm has been developed to overcome the lower SNR issue. 96% accuracy rate (?±2 bpm) has been achieved in our preliminary test study for various use cases on five human subjects.
