A common challenge for children with asthma is the requirement of a
forced expiratory test called spirometry. Masimo’s SpCO product
provides a noninvasive measurement from the Rainbow SET Pulse
CO-Oximeters and sensors that are already used in many hospitals.
Results are obtained without requiring patient instruction or breathing
As a result, SpCO may help to improve the assessment
of asthma severity and response to treatment in young children and
patients who are unconscious, heavily sedated, unable to understand and
follow instructions, or have limitations that would interfere with
vigorous respiratory efforts.
"We have limited measures to
assess severity of acute asthma exacerbations and the finding of an
association between carboxyhemoglobin (SpCO) by multi-wavelength Pulse
CO-Oximeter may have clinical importance," states Donald H. Arnold,
M.D., MPH, associate professor of Emergency Medicine and Pediatrics,
Vanderbilt University School of Medicine. "Our preliminary results
suggest that SpCO is a measure of oxidative stress and inflammation in
pediatric patients with acute asthma exacerbations."
