Pulse oximetry screening is a safe, painless and simple test that has been shown, in research studies involving almost half a million babies, to identify babies with life-threatening heart defects (critical congenital heart defects or CCHD) before they become seriously unwell.
"They have been considering routine pulse oximetry screening for critical heart defects in newborn babies for a number of years.
In Nigeria, the measurement of SpO[sub]2 by means of pulse oximetry is routinely done both for children with hypoxia-related illness such as cyanotic congenital cardiac defects and pneumonias.
Once the pulse oximetry screen showed a steady reading, the oxygen saturation was recorded.
In the present study, we demonstrated that a combination of BMI and pulse oximetry data might provide accurate results for predicting OSAS in cases where it is difficult to access PSG and in circumstances where large populations need to be screened for OSAS.
If there is crosstalk in pulse oximetry sensor like Figure 1(b), detected light intensity will be I([lambda]) + [I.sub.c]([lambda]), and the MBVSYS for ref PPG is rewritten as Equation (6),
Aim of this study is to find out whether this pulse oximetry method (disappearance and/or reappearance of plethysmographic waves and/or average of both) can reliably be used for measuring BP of neonates.
Conclusion: The measurement of pre-and post-ductal oxygen saturation by pulse oximetry was an effective screening tool for the detection of critical congenital heart defects in newborns.
Specific wavelengths of ?P=660nm & 940nm with narrow spectral bandwidths provide the perfect LED solution for pulse oximetry applications.
This present meta-analysis was performed to confirm the diagnostic role of pulse oximetry for CHD.
Noninvasive monitoring company Masimo (NasdaqGS:MASI) said on Sunday that its Masimo Foundation has co-founded the first-of-its-kind United for Oxygen Alliance under the Clinton Global Initiative (CGI) commitment to expand access to medical oxygen and pulse oximetry for women and children in Ethiopia.
In 2009, a large prospective screening study in Sweden which included over 39,000 infants demonstrated significant increases in the sensitivity of detecting CCHD from 63% with physical examination alone to 83% with the addition of pulse oximetry to the physical examination.
