Background Pulse-oximetry (Spo2) widely uses as a help tools for therapeutic interventions in the pediatric intensive care units (PICU). The aim of this study was to evaluate the validity of Spo2 in measuring of oxygenation index (OI) in children. Materials and Methods In a descriptive analytical study, 100 patients who were admitted to PICU Tabriz Children's Hospital were studied. Oxygenation ...

OBJETIVO: Descrever caso de uma paciente adulta com COVID-19, internada em unidade terapia intensiva (UTI) e submetida à posição prona.
 RELATO DO CASO: do sexo feminino, 44 anos, portadora síndrome metabólica prévia, da imunodeficiência adquirida, chegou ao pronto atendimento apresentando febre, congestão nasal, negando dispneia. Após a realização exames clínicos imagem, foi transferida p...

UNLABELLED The ratio of arterial oxygen tension to inspired oxygen fraction (PaO2/FiO2) is a useful indicator for weaning patients from mechanical ventilation and a reliable predictor of pulmonary dysfunction after cardiac surgery. The aim of this study was to elucidate the patient characteristics and variables that affect the PaO2/FiO2 ratio. Between 1994-1998, 167 patients who underwent coron...

BACKGROUND The use of intraoperative pulse oximetry (SpO2) enhances hypoxia detection and is associated with fewer perioperative hypoxic events. However, SpO2 may be reported as 98% when arterial partial pressure of oxygen (PaO2) is as low as 70 mm Hg. Therefore, SpO2 may not provide advance warning of falling arterial oxygenation until PaO2 approaches this level. Multiwave pulse co-oximetry ca...

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...

Pulmonary gas distribution, functional residual capacity (FRC), closing capacity (CC), arterial oxygen tension (PaO2) and alveolar-arterial oxygen tension gradient (PAO2-PAO2) were measured in seven subjects before and after the induction of extradural analgesia for routine surgery. It was found that pulmonary gas distribution was within normal limits throughout the study, although there were t...

The value of D-dimer value, lactic acid levels, and the results blood gas analysis (PaO2, PCO2, PH, PaO2/FiO2) are prognostic factors for COVID-19 patients, although there is no agreement on optimum cut-off point specificity sensitivity. aim this study to examine as a prognosis patients with severe or critical COVID-19. This was retrospective medical records UGM Academic Hospital. Overall survi...
