Pulse oximeters are used to noninvasively measure oxygen saturation in arterial blood (SaO2). Although arterial oxygen saturation measured by pulse oximeter (SpO2) is usually indicated in 1% increments, the value of SaO2 from arterial blood gas analysis is not an integer. We have developed a new pulse oximeter that can measure SpO2 to one digit after the decimal point. The values of SpO2 from t...
Pulse oximeter probes attached to the finger may fail to estimate blood oxygen saturation (SpO2) in patients with compromised peripheral perfusion (e.g. hypothermic cardiopulmonary bypass surgery). The measurement of SpO2 from a central organ such as the oesophagus is suggested as an alternative to overcome this problem. A reflectance oesophageal pulse oximeter probe and a processing system imp...
HYPOTHESIS The changes reported with pulse oximetry after the injection of isosulfan blue for sentinel lymph node identification in patients with breast cancer are consistent and predictable. DESIGN Retrospective study. SETTING University hospital. PATIENTS AND METHODS The complete anesthesia records of 92 patients who underwent sentinel lymph node biopsy with intraparenchymal injection o...

OBJECTIVE To evaluate clinical applicability of noninvasive hemoglobin (Hb) measurement with a pulse CO-oximeter in neonates. DESIGN Prospective comparison study. SETTING Neonatal ICU. PATIENTS Fifty-six preterm and term infants with median age = 20 days (range = 1-98 days) and median weight = 1,440 g (range = 530-4,230 g). INTERVENTIONS Hb measurements by Pulse CO-Oximetry (Masimo Radi...
This paper will design a non-invasive pulse oximeter using the ADuC842 microcontroller. A pulse oximeter is a medical device that indirectly monitors the oxygen saturation of a patient's blood and heart rate. The hardware has been developed for the pulse oximeter and programming/coding has been done for calculating blood oxygen saturation and pulse rate of a patient. The results are displayed o...
Background: Pulse Oximeter monitoring has become so common over previous decades that in some health care units, blood oxygen level is now considered as the fifth vital sign. However, it seems there is still some lack of knowledge and/or experience among medical staff operating pulse oximeter and interpreting its results. The aim of this study was to investigate and compare the knowledge on Pul...
