Good luck with your project! 1  Removal of old roof shingles ($90 per square, which is a term used to represent 100 square feet). 2  Install new shingles ($115 per square). 3  Purchase new shingles ($80-$125 per square). 4  Roofing Felt ($45 for a 4 square roll).hanks! Thomas K. ~ Pittsfield, Massachusetts. Thomas, I estimate that it could cost between $10,000 and $15,000 to replace a 2,500 square foot roof, which would be approximately $4-$6 a square foot.
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.
Pulse oximetry is a useful tool for assessing oxygen saturation, but it doesn't provide a complete picture of your patient's respiratory status. Understanding what pulse oximetry can and can't do will help you to use this technology wisely.o interpret pulse oximetry values correctly, you need to understand the oxyhemoglobin dissociation curve, which illustrates the relationship between arterial oxygen saturation (for our purposes, SpO 2 or SaO 2) and the amount of oxygen that is dissolved in the blood (partial pressure of oxygen, PaO 2).
