Key result
In patients with heart failure and oxygen saturations <90%, ear oximetry is the most accurate sensor location.
Why the study?
Despite its wide clinical use, few studies have assessed the role, accuracy, and precision of pulse oximetry across different sensor locations in patients with heart failure.
Does sensor location affect the accuracy and precision of pulse oximetry in patients with heart failure?

Does sensor location affect the accuracy and precision of pulse oximetry in patients with heart failure?
Ear oximetry is the most accurate location for pulse oximetry in heart failure patients when oxygen saturations are <90%.
Supports site-specific oximetry in HF subgroups; leaves open need for prospective validation before changing practice.
BACKGROUND: Despite its wide use in clinical practice, few studies have 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: ) was reported in 3 groups of patients with heart failure (HF); those with ejection fraction (EF) >40%, those with EF <40%, and those with acute HF (AHF) with ST and non-ST segment elevation acute myocardial infarction (STEMI and non-STEMI). RESULTS: saturations <90%, ear oximetry is the most accurate. CONCLUSION: saturations <90%, ear oximetry is the most accurate. Further studies are warranted.
