Newborn screening for critical congenital heart disease using pulse oximetry: The most common congenital disorder in newborns is congenital heart disease (CHD). In the first year of life requiring surgery or catheter- based intervention is known as Critical CHD. Normally in case of infants with critical cardiac lesions, the risk of morbidity and mortality increases when there is a delay in diagnosis and timely referral to a tertiary center with expertise in treating these patients. Pulse oximetry: it is a non-invasive method for monitoring a person's oxygen saturation. The application mode of pulse oximetry includes, a sensor device is placed on a thin part of the patient's body, usually a fingertip or earlobe, or in the case of an infant, across a foot. In this process the device passes two wavelengths of light through the body part to a photodetector. The changing absorbance at each of the wavelength are measured by this, which allowing it to determine the
