OBJECTIVE To assess the utility of umbilical cord venous blood gas measures for prediction of umbilical artery pH and base deficit acidemia. METHODS A retrospective cohort study was conducted of all singletons with valid paired arterial and venous cord gas samples delivered at our institution from January 2006 to March 2012. Fetal acidemia was defined primarily as cord arterial blood gas pH l...
BACKGROUND Arterial blood gas (ABG) analysis is not a routine test in sleep laboratories due to its invasive nature. Therefore, the diagnosis of obesity hypoventilation syndrome (OHS) is underestimated. We aimed to evaluate the differences in subjects with OHS and pure obstructive sleep apnea (OSA) and to determine clinical predictors of OHS in obese subjects. METHODS Demographics, body mass ...
BACKGROUND The aim of the study was to evaluate the adequacy of diagnosis and management of respiratory failure (RF) in COPD. METHODS Retrospective analysis of the hospital discharge forms of COPD patients hospitalized for RF from January 2007 to June 2008. Using the clinical audit tool, the primary end point was the accuracy of RF diagnosis. The secondary end points were mortality, re-hospit...
INTRODUCTION Improving tissue oxygenation is one of most important tasks in management of low cardiac output. Central venous oxygen saturation (ScvO2) and lactate are established criteria for monitoring the adequacy of tissue oxygenation. The venous-to-arterial carbon dioxide difference [P(v-a)CO2] is inversely associated with cardiac output. AIM To study the use of P(v-a)CO2/C(a-v)O2 ratio a...
Interpretation of Arterial blood gases is an essence of critical care. It helps for the assessment of clinical oxygenation, ventilation and acid-base status in critically ill patients. The four closely inter-related physiological parameters pH, PCO2, HCO3 and PO2 helps to diagnose, monitor and manage the ICU patients. Its correct interpretation and application necessitates the knowledge of basi...
BACKGROUND Despite the increasing number of geriatric horses attended by veterinarians, there is a lack of understanding of aging-related changes on the respiratory system of horses. OBJECTIVE To identify aging-related changes on the respiratory function and bronchoalveolar lavage fluid (BALF) cytology of horses. ANIMALS Fifteen healthy young adult (2-11 years) and 16 healthy aged (≥20 year...
Background & Objective: Chronic obstructive pulmonary disease(COPD) is one of the most common causes of emergency department or hospital admissions in our country. COPD is a chronic progressive inflammatory disease that affects the elderly. Considering these facts, COPD is taken into account as a major cause of disability in developed and developing countries. The purpose of this study is t...
BACKGROUND The prognostic value of arterial blood gases (ABG) in patients with acute decompensated heart failure (ADHF) is not well-established. We therefore conducted the present study to determine the relationship between ABG on admission and long-term mortality in patients with ADHF. METHODS We studied 588 patients consecutively admitted to our department with ADHF. ABG and classical progn...
abstract background: chronic obstructive pulmonary disease (copd) is a major cause of morbidity and mortality, and is an important health economic problem. since 1960, there has been an increase in mortality associated with copd, especially in men. acute exacerbations form a major component of the socioeconomic burden of copd which mainly results in long-term hospitalization. despite the high...
