Unobtrusive sleep state measurements in preterm infants – A review

“…In adult patients, BCG showed almost the same results as classic PSG for sleep classification(62). The test on a preterm infant showed a very high correlation between an ECG Unobtrusive preterm sleep-state measurements 16 reference and a BCG of 0.91, and a BR reference and a BCG of 0.74, proving BCG to be a suitable alternative for detecting HR and BR in preterm infants(61). There are commercial products for infants using BCG, for example, AngelCare (www.angelcare.de) or NannyCare (www.nannycare.nl), but they are mostly used as sudden infant death syndrome alarm systems rather than continuous monitoring devices.BCG methods pose a difficulty in designing algorithms to separate HR and BR from motion and noise.…”

“…and even tested in the NICU(61). In adult patients, BCG showed almost the same results as classic PSG for sleep classification(62).…”

A systematic review of novel technology for monitoring infant and newborn heart rate

“…After inclusion of four additional studies identified through references and citation of eligible studies , 15 articles were identified for analysis in this review .…”

“…The technologies assessed by these studies were camera‐based photoplethysmography , reflectance PO , laser Doppler methods , capacitive sensors , piezoelectric sensors , transcutaneous electromyography , and a digital stethoscope . Appendix contains brief, plain‐language descriptions of these technologies.…”

“…) show that one of the main limitations identified was patient selection as a potential source of bias. Only one of the articles specified randomised patient selection , and most of the articles did not describe how patients were selected . In addition, a number of studies used restrictive inclusion criteria in selecting patients without providing a suitable justification.…”
