Potential Use of Pulse Oximetry for the Diagnosis of Testicular Torsion Scrotal Doppler ultrasonography (scrotal US) has been commonly used for evaluating patients with suspected testicular torsion (TT).1,2However, scrotalUS isnot available in allmedical facilities. Comparatively, pulse oximetry is easily available at all institutions; it is used for monitoring pulse oximeter saturation (SpO2) ...

Introduction Reliable and accurate pulse oximetry requires the design and operation of the entire system to function together. Contributions ranging from the sensor technology, cabling and electronics, signal processing and alarm technologies, to communicating results to caregivers through local and remote displays, are all critical and interrelated (Figure 1). Many years of experience in each ...

One hundred and twenty five measurements of arterial oxygen saturation (Stcao2) obtained with a transcutaneous pulse oximeter were compared with direct arterial oxygen tension (Pao2) in 13 preterm infants with predominantly fetal haemoglobin. Stcao2 of 86-92% corresponded to Pao2 of 5-13 kPa. Stcao2 above 92%, however, was sometimes associated with Pao2 above 13 kPa.

Hemoglobin is the most important blood parameter. Hemoglobin is the protein in red blood cells that carry oxygen to the body. Low level of hemoglobin can be due to disease like anemia and high hemoglobin level may be due to polycythemia Vera. Conventional methods are mostly used to calculate hemoglobin level. These methods involve pricking of blood with needle and sending it to laboratory for f...

A photonic approach to the simultaneous measurement of the frequency, pulse amplitude (PA), pulse width (PW), and time of arrival (TOA) of an unknown pulsed microwave signal is proposed and demonstrated. The measurement is performed based on optical carrier-suppressed modulation, complementary optical filtering, low-speed photodetection, and electrical signal processing. A proof-of-concept expe...

BACKGROUND The purpose of this statement is to address the state of evidence on the routine use of pulse oximetry in newborns to detect critical congenital heart disease (CCHD). METHODS AND RESULTS A writing group appointed by the American Heart Association and the American Academy of Pediatrics reviewed the available literature addressing current detection methods for CCHD, burden of missed ...
