Some characteristics of Bacillus subtilis phage SPO2 which show that it is a temperate phage are presented. Wild-type SPO2 forms turbid plaques, similar to those of other temperate phages. SPO2 lysogenic strains which are resistant to SPO2 can be isolated; these strains remain stable lysogens despite the fact that they can no longer adsorb SPO2. SPO2 lysogenic strains can be grown for many gene...

BACKGROUND Worsening of pulmonary diseases is associated with a decrease in oxygen saturation (SpO2). Such a decrease in SpO2 and associated factors has not been previously evaluated in a general adult population. AIM We sought to describe SpO2 in a sample of adults, at baseline and after 6.3 years, to determine whether factors predicting low SpO2 in a cross-sectional study were also associat...

OBJECTIVE For children with cyanotic congenital heart disease or acute hypoxemic respiratory failure, providers frequently make decisions based on pulse oximetry, in the absence of an arterial blood gas. The study objective was to measure the accuracy of pulse oximetry in the saturations from pulse oximetry (SpO2) range of 65% to 97%. METHODS This institutional review board-approved prospecti...

AIM Providing consistent levels of oxygen saturation (SpO2 ) for infants in neonatal intensive care units is not easy. This study explored how effectively the Auto-Mixer(®) algorithm automatically adjusted fraction of inspired oxygen (FiO2 ) levels to maintain SpO2 within an intended range in extremely low birth weight infants receiving supplemental oxygen without mechanical ventilation. METH...

Up to a third of ex-preterm infants flying near term exhibit pulse oxygen saturation (SpO2) of less than 85% during air travel. A hypoxia challenge test (HCT) is recommended to evaluate the requirement for in-flight supplemental O2. The validity of the HCT in healthy, term infants has not been reported. This study aimed to characterise the in-flight hypoxia response and the accuracy of the HCT ...

BACKGROUND The contribution of obesity to hypoxemia has not been reported in a community-based study. Our hypothesis was that increasing obesity would be independently associated with lower SpO2 in an ambulatory elderly population. METHODS The Cardiovascular Health Study ascertained resting SpO2 in 2,252 subjects over age 64. We used multiple linear regression to estimate the association of b...

OBJECTIVE Because the optimal concentration of oxygen (FiO2) required for stabilization of the newly born infant has not been established, the FiO2 is commonly adjusted according to the infant's oxygen saturation (SpO2). We aimed to determine the range of pre-ductal SpO2 in the first minutes of life in healthy newborn infants. STUDY DESIGN We applied an oximetry sensor to the infant's right p...

background: the study was aimed to explore the association between arterial oxygen saturation (spo2) and spirometer parameters of disease severity in copd patients with a view to identify whether the pulse oximetry can be used as an alternative to arterial values in the clinical management of copd patients in a routine practice. materials and methods: thirty-one patients with copd were included...

In the ambulatory surgical setting, patients may present with grossly abnormal oxygen saturation (Spo2) readings that, along with other disease pathology, make referral to an inpatient facility a straightforward decision. Patients presenting with unexplained slightly abnormal Spo2 readings might make evaluation as an appropriate candidate for the ambulatory setting more problematic. Little guid...
