BONUS +2    Carbon-12 is stable, meaning it never undergoes radioactive decay. Carbon-14 is unstable and undergoes radioactive decay with a half-life of about 5,730 years (meaning that half of the material will be gone after 5,730 years). This decay means the amount of carbon-14 in an object serves as a clock, showing the object’s age in a process called “carbon dating.” This is all because of….?

A patient has been admitted through the ED with increasing SOB for the past 3 days. The CXR reveals opacities in the RML and RLL. The patient presents with the following clinical data: ABG: pH 7.53, PCO2 = 29, PO2 = 78, HCO3 = 24 on 2 L/min (28% FiO2) of O2, HR = 123 bpm, RR = 28 bpm, B/P = 172/89. 1) What is the P(A-a)O2 difference and what does it indicate?2) What is the P/F ratio and what does it indicate?
