Objective: Over the last 15 years, developments in camera technology have coincided with
increased availability and affordability. This has led to an increasing interest in using these …

Research into methods to assess heart rate and respiration rate through non-contact means
has been ongoing for many years [1], and this work has expanded in scope in recent years …

Recently, noncontact monitoring of respiratory rate (RR) based on consumer-level cameras
has gained increasing attention. However, motion artifacts with large amplitudes usually …

Vital signs monitoring is ubiquitous in clinical environments and emerging in home-based
healthcare applications. Still, since current monitoring methods require uncomfortable …

Respiratory rate (RR) is an often underestimated and underreported vital sign with
tremendous clinical value. As a predictor of cardiopulmonary arrest, chronic obstructive …

An abnormal respiratory rhythm is an early indicator of physiological deterioration. It is of
critical importance in the clinical management of critically-ill or premature infants, for whom …

Individuals with obstructive sleep apnea (OSA) can experience partial or complete collapse
of the upper airway during sleep. This condition affects between 10-17% of adult men and 3 …

There is considerable interest in the noncontact monitoring of patients as it allows for
reduced restriction of patients, the avoidance of single-use consumables and less patient …

Imaging photoplethysmography (iPPG) allows for remote measurement of vital signs from
the human skin. In some applications the skin region of interest may only occupy a small …

Background To validate the accuracy of ultra-wideband (UWB) wireless radar for the
screening diagnosis of sleep apnea. Methods One hundred and seventy-six qualified …
