Background: Despite its wide use in clinical practice, few studies had assessed the role of pulse oximetry in patients with heart failure. We aimed to evaluate the accuracy and precision of the pulse oximeter in patients with heart failure and to determine this accuracy at three different sensor locations.Methods: Comparison of pulse oximetry reading (SpO2) with arterial oxygen saturation (SaO2) was reported in 3 groups of patients with heart failure (HF); those with ejection fraction (EF) >40%, those with EF 40% and AHF with O2 saturations >90%, finger oximetry is the most accurate and reliable, while in HF with EF 40% and in AHF with O2 saturations >90%, finger oximetry is the most accurate and reliable, while in HF with EF<40% and in patients with AHF with O2 saturations <90%, ear oximetry is the most accurate. Further studies are warranted.
