Infants admitted to health-care centers with acute bronchiolitis are frequently monitored with a pulse oximeter, a noninvasive method commonly used for measuring oxygen saturation. The decision to hospitalize children with bronchiolitis has been largely influenced by pulse oximetry, despite its questionable diagnostic value in delineating the severity of the illness. Many health-care providers ...

PURPOSE To establish situations in which family physicians (FPs) consider pulse oximetry a valuable addition to their clinical patient assessment; to explore pulse oximetry results (SpO(2)) when used by FPs in patients with chronic obstructive pulmonary disease (COPD); to explore associations between SpO(2) and other markers of COPD severity. METHODS We performed three separate studies: (i) i...

Pulse oximetry is a well-established tool routinely used in many settings of modern medicine to determine a patient's arterial oxygen saturation and heart rate. The decreasing size of pulse oximeters over recent years has broadened their spectrum of use. For diagnosis and treatment of sleep-disordered breathing, overnight pulse oximetry helps determine the severity of disease and is used as an ...

STUDY OBJECTIVES The purpose of this cross-sectional study was to confirm the observation that pulse oximetry tracing correlates with pulsus paradoxus, and is therefore a measure of the severity of air trapping in obstructive airway disease. DESIGN Cross-sectional survey. SETTING The ICU in a tertiary care academic hospital. PATIENTS Twenty-six patients consecutively admitted to the ICU w...

OBJECTIVE To compare strategies with and without first-day of life pulse oximetry screening to detect critical congenital heart defects (CCHDs). STUDY DESIGN Population based study including all live born infants in Norway in 2005 and 2006 (n = 116 057). Postductal (foot) arterial oxygen saturation (SpO(2)) was measured in apparently healthy newborns after transferral to the nursery, with SpO...

Congenital heart disease (CHD) is one of the most common birth defects, with an incidence of nine out of every 1,000 live births. The mortality of infants with CHD has decreased over the past 3 decades, but significant morbidity and mortality continue to occur if not diagnosed shortly after birth. Pulse oximetry was recommended as a screening tool to detect critical CHD in 2011 by the American ...

complexity of some congenital heart diseases sometimes necessitates a combination of interventional procedures and surgery, amongst which intraoperative stent implantation is one of the most common. we herein report a successful hybrid procedure in a cyanotic adult patient who had undergone no procedure in childhood. the patient was a 24-year-old cyanotic male (oxygen saturation in the room air...

Pulse oximetry is a useful way to monitor oxygen saturation in patients in a variety of clinical settings. Nurses need to understand the principles of oxygen transport and delivery to use pulse oximetry effectively in clinical practice.

The pulse oximeter has become a vital instrument in the care of infants and children with cardiopulmonary disease. Recent advances in pulse oximetry technology have improved some aspects of pulse oximeter performance. However, the reliability, accuracy, and clinical utility of pulse oximetry remain problematic in some types of patients under certain conditions. Improved signal processing techno...

Pulse oximetry has been one of the most significant technological advances in clinical monitoring in the last two decades. Pulse oximetry is a non-invasive photometric technique that provides information about the arterial blood oxygen saturation (SpO(2)) and heart rate, and has widespread clinical applications. When peripheral perfusion is poor, as in states of hypovolaemia, hypothermia and va...
