This study investigates the correlation between noninvasive hemoglobin monitoring (SpHb) and invasive hemoglobin measurement (InvHb) in guiding blood transfusions during thoracic surgeries. Methods: A non-interventional design was used to evaluate the relationship between SpHb and InvHb readings in the context of transfusion decisions. Data were obtained from 80 patients aged 18 years or older undergoing thoracic procedures. Continuous SpHb monitoring was performed, and concurrent InvHb samples were collected for comparison. The primary endpoint was the degree of correlation between SpHb and InvHb values.
