In reviewing the article “Methemoglobinemia: Sudden Dyspnea and Oxygen Desaturation After Esophagoduodenoscopy,” in the August 2004 issue of RESPIRATORY CARE,1 I found the article suggested that, during the esophagoduodenoscopy procedure the patient’s blood oxygen saturation (measured via pulse oximetry) began to drop rapidly, and a saturation of 54% registered on the pulse oximeter while the p...

STUDY OBJECTIVES Current Medicare guidelines include an apnea-hypopnea index (AHI) > or = 15 events per hour, in which all hypopneas must be associated with 4% desaturation, to qualify for reimbursement for therapy with continuous positive airway pressure (CPAP). The present data demonstrate the effect of pulse oximeter differences on AHI. DESIGN Prospective study, blinded analysis. SETTING...

Nowadays, many medical devices have been developed for the purposes of diagnosing and treatment. Wearable sensors and systems have evolved to the point that they can be considered ready for clinical application. The use of wearable monitoring devices that allow continuous or intermittent monitoring of physiological signals is critical for the advancement of both the diagnosis as well as treatme...

During cardiac catheterization it is an advantage to have an immediate indication of the oxygen content of blood samples withdrawn from the heart and great vessels while the catheter is still in situ. This is especially important in the more complex congenital defects as the procedure can then be modified if necessary in the light of the blood oxygen estimations. The present paper describes a w...

BACKGROUND Pulse oximetry is considered a standard of care in both the operating room and the postanesthetic care unit, and it is widely used in all critical care settings. Pulse oximeters may fail to provide valid SpO2 data in various situations that produce low signal-to-noise ratio. Motion artifact is a common cause of oximeter failure and loss of accuracy. This study compares the accuracy a...

BACKGROUND Pulse oximeters continuously monitor arterial oxygen saturation. Continuous monitoring of venous oxygen saturation (SvO2) would enable real-time assessment of tissue oxygen extraction (O2E) and perfusion changes leading to improved diagnosis of clinical conditions, such as sepsis. METHODS This study presents the proof of concept of a novel pulse oximeter method that utilises the co...

The objective of the research centered on how pulse oximeter was used to identify heart rate dynamics when performing free throws under standardised conditions in male and female experimental groups (U14-U18). study conducted 2021, functional test consisted monitoring with help during execution ‚’10 Experimental Throws Test’ varies throws. In case test, differences monitored oximeter, recorded ...
