AMSTERDAM, June 6, 2016 /PRNewswire/ -- Royal
Philips (NYSE: PHG AEX: PHIA) today announced the results of the
first published study to demonstrate that absolute oxygen
saturation of arterial blood (SpO2), a vital sign that
is commonly monitored in hospitalized and other patients, can be
accurately measured across multiple patients using contactless
technology. The study, published in the June issue of the
journal Anesthesia & Analgesia, used Philips proprietary
camera-based monitoring technology to measure the light reflected
off the foreheads of 41 healthy adults to calculate
SpO2. Through the results of this study, Philips, a
global leader in patient care and monitoring solutions, is the
first to demonstrate that contactless SpO2 can be
calibrated across patients, just like conventional contact probes,
allowing accurate measurements without individual adjustments.
In many care settings, monitoring heart rate, arterial blood
oxygenation, respiration rate, and activity is a standard part of
patient care to detect complications or deterioration. The current
method for measuring these key vital signs requires the use of
sensors on the skin or devices strapped to the body; however, these
contact sensors may cause damage and distress in patients with
fragile skin such as newborn babies.
"Vital signs monitoring is crucial across all types of care
settings, but for patient populations with specific conditions,
managing their care in a less intrusive way is critical in order to
avoid unnecessary distress," said Carla Kriwet, CEO of Philips
Patient Care & Monitoring Solutions. "Contactless monitoring
solutions will offer clinicians with a way to accurately measure
vital signs for patients in a non-obtrusive way, and provide them
with the data needed to know when to intervene."
A Contactless Alternative
For specific patient populations, including premature infants in
the NICU, a contactless alternative would provide potential
advantages such as avoiding skin damage in fragile patients and
freedom to select a more physiologically central location with a
possible faster response rate[1][2]. With every heartbeat, the
cardiovascular pressure wave causes tiny 'micro-blushes' (small
changes in skin color) in the face. While these changes are not
visible to the human eye, Philips' contactless monitoring
algorithms can calculate an accurate pulse rate by quantifying
these changes.
Over the past 10 years, an increasing number of papers[3] have
published on the topic of contactless monitoring in the measurement
of pulse or respiration rate; however, only a handful have explored
SpO2[4] and this is the first study that has been able
to convincingly demonstrate that calibrated contactless monitoring
of absolute blood oxygen levels is possible. In this recent study,
calibration of contactless, camera-based pulse oximetry was
performed on a population of 41 healthy adults and the results are
promising for the successful use of contactless monitoring for
absolute blood oxygen levels in care settings without individual
adjustments.
This study is the latest from Philips in its longstanding
leadership in the area of contactless monitoring. In addition to
the successful results of this study, Philips' contactless
monitoring solutions show promise for accurately measuring key
vital signs such as heart rate and respiration rate. Philips is
well-positioned to leverage its expertise and leadership in patient
monitoring to tailor contactless solutions for monitoring
applications across the care continuum.
