Nonintrusive vital signs monitoring for sleep apnea patients: A preliminary study

“Current approaches for sleep-disordered breathing detection are intrusive and can affect the patient’s sleep quality. Ten patients scheduled for drug-induced sleep endoscopy were recruited to determine the utility of a novel unobtrusive microbend fiber optic sensor mattress (cardioballistography technology) to monitor heart rate, respiratory rate, apnea and hypopnea episodes. Pearson correlation coefficient between the proposed sensor and the reference device was 0.96 and 0.78 for heart rate and respiration, respectively. The proposed sensor provided a low sensitivity (24.24±12.81%) and high specificity (85.88±6.01%) for sleep apnea detection. It is expected that this preliminary research will pave the way toward unobtrusive detection of vital signs in real time.”
