Photo-Plethysmographic (PPG) Camera to Monitor Heart Rate, Respiration Rate and Oxygen Saturation in Infants

2014-08-27 03:18:52 | BioPortfolio


The researchers want to determine if ambient light, PPG, can monitor reliably heart rate, respiration rate and oxygen saturation (SpO2) in infant patients in a hospital setting.


The plethysmographic signal is typically strong on children. This provides a reliable heart rate monitor. However, to measure oxygen saturation, a quantitative value of the strength at two wavelength regions (green and red) is required. It is also not known if the normal ambient light is spectrally appropriate to analyze the video signals for oxygenation. With the current prototype of our system, we can monitor heart rate reliably and estimate oxygen saturation in adults, using normal artificial light or daylight, entering through a window. Heart rate and oxygen saturation will be extracted from the PPG signals off the cheek, forehead or hand while the respiration rate may be retrieved from the PPG signal off the chest area.

Medical and Biotech [MESH] Definitions

A child whose needs, abilities, or other characteristics vary so much from the average in mental, physical, or social areas that a greater than usual level of services is needed to facilitate the child's maximum potential development.

The language and sounds expressed by a child at a particular maturational stage in development.

Severe distortions in the development of many basic psychological functions that are not normal for any stage in development. These distortions are manifested in sustained social impairment, speech abnormalities, and peculiar motor movements.

Performing the role of a parent by care-giving, nurturance, and protection of the child by a natural or substitute parent. The parent supports the child by exercising authority and through consistent, empathic, appropriate behavior in response to the child's needs. PARENTING differs from CHILD REARING in that in child rearing the emphasis is on the act of training or bringing up the children and the interaction between the parent and child, while parenting emphasizes the responsibility and qualities of exemplary behavior of the parent.

Component of the NATIONAL INSTITUTES OF HEALTH. It was initially established to investigate the broad aspects of human development as a means of understanding developmental disabilities, including mental retardation, and the events that occur during pregnancy. It now conducts and supports research on all stages of human development. It was established in 1962.
