Next generation of non-contact and wireless vital sign monitoring technology in the neonatal intensive care unit: a systematic review

Most emerging technologies are non-contact technologies monitoring one vital sign, usually respiratory rate (RR), and a minority were wireless wearable sensors monitoring more than one vital sign usually heart rate and RR and showed good accuracy. Studies had small sample sizes, short recording durations, and exclusively focused on accuracy, and often missing important information about participants and study methodology. Wireless and non-contact technologies show promise, and this review provides recommendations to improve study design, extend recording durations, and enhance transparency in reporting and participant selection.
