A novel hemoglobin, Bonn, causes falsely decreased oxygen saturation measurements in pulse oximetry.
BACKGROUND A 4-year-old boy and his father exhibited low oxygen saturation measured transcutaneously by pulse oximetry, a finding that could not be confirmed by arterial blood gas analysis. Both patients exhibited slight hemolysis in their blood, and the boy had a microcytic anemia. There was no evidence of hypoxemia or methemoglobinemia. Despite the normal results from the arterial blood gas a...
متن کاملPulse Oximetry Overestimates Oxygen Saturation in COPD.
BACKGROUND Measurement of oxygen saturation with a handheld pulse oximeter is widely practiced as a surrogate to invasive arterial blood gas analysis. Oxygen saturation is an important parameter in cases of COPD, but there are insufficient data on the role of pulse oximetry in patients with COPD, moreso in diseases across its spectrum, such as chronic bronchitis and emphysema. We assessed the p...
متن کاملThe measurement of dyshemoglobins and total hemoglobin by pulse oximetry.
PURPOSE OF REVIEW Recent advances in pulse oximetry have made it possible to noninvasively measure total hemoglobin, as well as the two most common dyshemoglobins. This review will trace the development and clinical application of multiwavelength pulse oximetry. RECENT FINDINGS Until now, commercially produced pulse oximeters have utilized two wavelengths of light and could measure only the r...
متن کاملAbout Chediak-Higashi, Hemoglobin Lansing, and Hemoglobin Jabalpur
To the Editor, I would like to express my concerns about some of the published letters in a recent issue of this journal. About “A Rare Cause of Recurrent Oral Lesions: Chediak-Higashi Syndrome” by Karabel et al. [1], I feel that unbelievably low neutrophil counts (157/L ?) and/or coinciding presence of another hereditary disorder such as acatalasemia [2] should also be looked for as a cause of...
متن کاملPulse oximetry and factors associated with hemoglobin oxygen desaturation in children with sickle cell disease.
The observation of low transcutaneous arterial oxygen saturation (SaO2) in otherwise well sickle cell patients has lead to questions about the interpretation of pulse oximetry values in these patients. We undertook a prospective study of children with sickle cell disease to (1) determine the prevalence of, and factors associated with, low transcutaneous SaO2 in clinically well patients, (2) dev...
