Accordingly, it would also be interesting to have answers to the following questions concerning Global Initiative for Chronic Obstructive Lung Disease stage IV chronic obstructive pulmonary disease patients. 1) How many patients with a ground-level arterial oxygen saturation measured by pulse oximetry of .95% underwent hypoxic challenge testing? 2) How many patients flew without oxygen and with...

BACKGROUND The incidence, severity, and duration of postoperative oxygen desaturation in the general surgical population are poorly characterized. We therefore used continuous pulse oximetry to quantify arterial oxygen saturation (SpO2) in a cross-section of patients having noncardiac surgery. METHODS Oxygen saturation, blinded to clinicians, was recorded at 1-minute intervals in patients >45...

This study focuses on analysis of the relationship between changes in blood oxygen saturation (SaO(2)) and heart rate (HR) recordings from nocturnal pulse oximetry (NPO) in patients suspected of suffering from obstructive sleep apnoea (OSA) syndrome. Two different analyses were developed: a classical frequency analysis based on the magnitude squared coherence (MSC) and a nonlinear analysis by m...

OBJECTIVE This study tested the effects of low perfusion caused by emerging sepsis on the reliability of a new pulse oximetry technology (Masimo SET; IVY 405T) compared with a standard pulse oximeter (Nellcor N-200). DESIGN Randomized trial. SETTING University animal research facility. SUBJECTS Twenty-six anesthetized, ventilated (Fio, 1.0), adult rabbits. INTERVENTIONS Pneumonia/sepsis...

Pulse oximetry is a frequently used tool in anesthesia practice. Gives valuable information about arterial oxygen content, tissue perfusion and heart beat rate. In this study we aimed to provide the comparison of peripheral capillary hemoglobin oxygen saturation (SpO2) values among every finger of the two hands. Thirty-seven healthy volunteers from operative room stuffs between the ages of 18-3...

background: prematurity is the main cause of death in infants under one years of age and is the main reason for nicu hospitalization. the stressful environment of nicu exposes preterm infants to inappropriate stimuli. this study aimed to determine and compare the mean of heart rate and oxygen saturation of premature infants before and during a designed program in nicu. methods: in a clinical tr...

BACKGROUND Because patients with chronic heart failure (CHF) can benefit from specific treatment for coexisting obstructive and central sleep apnea (CSA), there is a need to develop accurate screening tools to identify or exclude these sleep-related breathing disturbances (SRBDs) in patients with CHF. OBJECTIVES To evaluate, prospectively, the diagnostic value of nocturnal home oximetry in id...

Pulse oximetry is an important non-invasive means of determining oxygen saturation in both animals and humans. However, it has not been standardized small ruminants. Hence, the present study envisages standardization pulse goats. Briefly, 36 respiratory affected goats were evaluated against healthy for at different sites (Pinnae, lower lip tip tail). The resistant to allow probes be placed lip....

The early detection and treatment of hypoxia is important to reduce patient morbidity in the accident and emergency department. At present, the commonly used methods all have practical difficulties in the urgent situations that prevail in the department. Pulse oximetry has recently become a method of choice in many anaesthetic and intensive care units for the continuous monitoring of oxygenatio...
