The placement and accuracy of pulse oximeter probes can vary markedly among species. For our study, we aimed to assess the accuracy of pulse oximetry and to determine the most clinically useful sites for probe placement in llamas and alpacas. The objectives included an analysis of pulse oximetry probes for accurate assessment of llamas and alpacas and to determine the best placement of the prob...

OBJECTIVE This study investigates the validity of transabdominal pulse oximetry using a sheep fetal hypoxia model with fetal arterial hemoglobin saturation. METHODS Four pregnant ewes were anaesthetized and cannulated through the brachial artery to measure direct arterial blood saturation, SaO(2). Next, the transabdominal pulse oximeter was used to measure indirect measurement of the arterial...

Introduction Post-operative patients with undiagnosed obstructive sleep apnea are at risk of sudden respiratory failure after receiving anesthesia because of repressed respiratory and hemodynamic responses [1] . While all patients have their oxygen saturation automatically monitor in the Post Anesthesia Care Unit (PACU), few have their respiration rate monitored. The goal of our study is to dev...

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 (SpO2) and heart rate, and has widespread clinical applications. When peripheral perfusion is poor, as in states of hypovolaemia, hypothermia and vaso...

INTRODUCTION This study investigates the relation between changes in pulse oximeter oxygen saturation (SpO2) and changes in arterial oxygen saturation (SaO2) in the critically ill, and the effects of acidosis and anaemia on precision of using pulse oximetry to predict SaO2. PATIENTS AND METHODS Forty-one consecutive patients were recruited from a nine-bed general intensive care unit into a 2-...

Incorporating of the new pulse oximetry feature into computer-aided fetal monitoring system requires a lot of modifications in hardware and software structure of the system. Since these modifications are fairly time-consuming, such a solution would be impracticable during preliminary testing and evaluation phases of new medical instrument. Therefore, at first we decided to build a prototype sys...
