BACKGROUND Hypoxemia is common during one-lung ventilation(OLV), predominantly due to transpulmonary shunt. None of the strategies tried showed consistent results. We evaluated the effectiveness of ventilating the operated, non-dependent lung (NDL) with small tidal volumes in improving the oxygenation during OLV. METHODS 30 ASA 1 and 2 patients undergoing elective, open thoracotomy were studi...

AIMS To describe the relation between oscillatory amplitude changes and arterial blood gas (ABG) changes in preterm infants receiving high frequency oscillatory ventilation, using a multiparameter intra-arterial sensor (MPIAS). METHODS Continuous MPIAS ABG data were collected after amplitude changes and stratified according to FIO(2): high (> 0.4) or low (< 0.3). For each amplitude change, th...

Most inaccuracies in the analysis of gases and electrolytes in arterial blood samples are due to preanalytic factors, among which is the type of equipment used for blood collection. Our objective was to compare arterial blood gas sample kits used under clinical conditions and to evaluate the impact of delay in estimation on variability in results. In 2 types of study we compared 5 kits (Radiome...

Background/Aims: The aim of present study was to find out profile and sequential pattern Arterial Blood Gas (ABG) in critically ill Corona Virus Disease 2019 (COVID-19) patients.&#x0D; Study Design: Observational prospective study.&#x0D; Methodology: A total 80 Reverse Transcription Polymerase Chain Reaction (RT PCR) positive cases; that needed ICU admission for their life-threatening condition...

Introduction and Aim: The advancement in the field of diagrammatic representation for diagnosis acid base disturbances is not significant. A graphical tool was published by Rajini Samuel ABG interpretation using standard excess, ratio (HCO3 - Std HCO3) / H2CO3 parameter (pCO2- 40 mm Hg) a four quadrant graph. In present study this constructed utilized disorders. Materials Methods:One hundred fi...

background : hepatopulmonary syndrome (hps) refers to arterial hypoxemia caused by pulmonary vasodilation, which is a consequence of portal hypertension. hps is associated with increased morbidity and mortality; thus, it is important to diagnose this entity as soon as possible for treatment to be administered. materials and methods: in a cross-sectional study, 40 children (6 months to 14 years ...

Pressure-controlled ventilation (PCV) is less frequently employed in general anesthesia. With its high and decelerating inspiratory flow, PCV has faster tidal volume delivery and different gas distribution. The same tidal volume setting, delivered by PCV versus volume-controlled ventilation (VCV), will result in a lower peak airway pressure and reduced risk of barotrauma. We hypothesized that P...

arterial blood gas parameters were analyzed in forty-nine healthy persons (31 males, 18 females) to detemine reference values fo these parameters and their relation to the time from last food intake to arterial puncture (t). the mean ± standard deviation of arterial oxygen pressure, arterial carbon dioxide pressure and ph at core body temperature were 84.4±7.0 mmhg (male: 83.0±6.5, female: 86.7...

introduction: arterial gas derangement could change urinary sodium excretion in chronic obstructive pulmonary disease (copd) patients.there are very few and conflicting data in regards to the measurement of fractional excretion of sodium in copd patients. the main aim of this study was to assess the relationship between renal fractional excretion of sodium(fena) with arterial blood gas and spir...
