Validity of Spo2/Fio2 Ratio in Detection of Acute Lung Injury and Acute Respiratory Distress Syndrome

Introduction:  One ofdiagnostic criteria for Acute Lung Injury and Acute Respiratory Distress Syndrome is  pao2/fio2 (PF) ratio 300 for ALI or 200 for ARDS. This criteria requires invasive arterial sampling. Measurement of Spo2/Fio2 (SF) ratio by pulseoximetry may be a reliable non invasive alternative to the PF ratio.   Methods and Materials: In a cross sectional study we enrolled 105 sample o...

ten, and contained information relevant for clinicians. Chapter 26, which covered positron emission tomography (PET), was surprisingly thin, especially given the robust amount of recently published information on PET in lung cancer diagnosis and staging. More information on PET technique, examples of PET/computed-tomography fusion images, and clinically-oriented recommendations (eg, when should...

Acute respiratory distress syndrome.

INTRODUCTION Acute respiratory distress syndrome (ARDS) is characterised by lung inflammation with severe hypoxia, which usually develops over 4-48 hours and persists for days or weeks. The main causes of ARDS are infections, aspiration of gastric contents, and trauma. Between a third and a half of people with ARDS die from the disease, but mortality depends on the underlying cause. Some surviv...

Acute respiratory distress syndrome.

The acute respiratory distress syndrome (ARDS) is a serious and complex clinical problem that often threatens the lives of patients. Emerging clinical data suggest that the survival of patients with this disorder may have improved during the last two decades, presumably because of advances in supportive medical care. Among the supportive therapies used to treat patients with ARDS, none is more ...
