The identification of congenital heart defects in the newborn can be complicated. After reading the article The nurse champion model for advancing newborn screening of critical congenital heart disease Discuss the following: Identify two (2) variables needed to promote the accuracy of pulse oximetry results in the newborn. Discuss why these variables are important to address. Identify two (2) benefits and two (2) limitations to performing a pulse oximetry on all newborns.
The oxygen level from a pulse oximeter is reasonably accurate. Most oximeters give a reading 2% over or 2% under what your saturation would be if obtained by an arterial blood gas. For example, if your oxygen saturation reads 92% on the pulse oximeter, it may be actually anywhere from 90 to 94%.The oximeter reading may be less accurate if a person is wearing nail polish, artificial nails, has cold hands, or has poor circulation.eams of light from the device pass through the Pulse oximetry is a way to measure how much oxygen your blood is carrying. By using a small device called a pulse oximeter, your blood oxygen level can be checked without needing to be stuck with a needle.
