The range of PaO2 variation determines the severity of oxygen-induced retinopathy in newborn rats.
PURPOSE This study was conducted to determine the potential influence of PaO2 fluctuation on the retinal neovascular response known to occur in newborn rats exposed to hyperoxic conditions. As an inherent corollary, the authors also defined the relationship between the fraction of inspired oxygen (FiO2) and the arterial blood oxygen tension (PaO2) in newborn rats. METHODS Experiment 1 was com...
متن کاملAssessment of PaO2/FiO2 for stratification of patients with moderate and severe acute respiratory distress syndrome
OBJECTIVES A recent update of the definition of acute respiratory distress syndrome (ARDS) proposed an empirical classification based on ratio of arterial partial pressure of oxygen to fraction of inspired oxygen (PaO₂/FiO₂) at ARDS onset. Since the proposal did not mandate PaO₂/FiO₂ calculation under standardised ventilator settings (SVS), we hypothesised that a stratification based on baselin...
متن کاملRelationship of Oxygen Saturation Percentage (SaO2) and Arterial Oxygen Pressure (PaO2) with the Outcome of Covid-19 Patients Hospitalized in intensive care Units
Background and Objective: In order to determine the Hypoxemia and prognosis of patients with covid-19 hospitalized in the intensive care unit, reliable oxygen supply indicators are needed. In this situation, the examination of the percentage of arterial oxygen saturation (SaO2) and arterial oxygen pressure (PaO2), as well as their relationship, may be helpful. Materials and Methods: This des...
متن کاملHigh-flow nasal cannula versus noninvasive positive pressure ventilation in acute respiratory failure: interaction between PaO2/FiO2 and tidal volume
We read with interest the systematic review by Zhao et al. [1] comparing the effect of the high-flow nasal cannula (HFNC) and noninvasive positive pressure ventilation (NIPPV) therapies in acute respiratory failure. Coincidentally, a similar review [2] was also published in Chest recently in which the cohort studies were also included. Both of these two reviews reported that, compared to HFNC, ...
متن کاملClinical relevance of the PaO2/FiO2 ratio
We read with interest the report by Karbing and coworkers [1] in which they assess the clinical relevance of variation in the arterial oxygen tension (PaO2)/fractional inspired oxygen (FiO2) ratio, a widely used oxygenation index, alongside changes in FiO2. In mechanically ventilated and spontaneously breathing patients, they showed that the clinical utility of PaO2/FiO2 ratio is doubtful unles...
