acute respiratory distress syndrome (ards) is a complex disorder of heterogeneous etiologies characterized by a consistent, recognizable pattern of lung injury and a potentially devastating form of acute inflammatory lung injury with a high short-term mortality rate and significant long-term consequences among survivors. recently, the new definition of ards has been published, and this definiti...
acute respiratory distress syndrome (ards) is a potential complication of cardiac surgery, given that patients undergoing cabg frequently have hypoxemia and pulmonary dysfunction during initial hours after surgery. thus, ards criteria in these patients are more likely to be positive while these criteria may not match the patient`s clinical picture. we aimed to investigate frequency of rapid ons...
Background & Aims: Diagnostic criteria for acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) requires acute onset of disease, chest radiograph demonstrating bilateral pulmonary infiltrates, lack of significant left ventricular dysfunction and Pao2/Fio2 (PF) ratio 300 for ALI or 200 for ARDS. And the latter one requires invasive arterial sampling. Measurement spo2 by pulse...
Background: Acute respiratory distress syndrome (ARDS) is one of the most important complications associated with traumatic brain injury (TBI). ARDS is caused by inflammation of the lungs and hypoxic damage with lung physiology abnormalities associated with acute respiratory distress syndrome. Aim of this study is to determine the epidemiology of ARDS and the prevalence of risk factors. Meth...
پیش زمینه و هدف: کرایتریاهای تشخیصی ali و ards شامل شروع حاد بیماری، یافته های رادیوگرافی سینه مطابق با انفیلتراسیون دوطرفه ریه و نبود اختلال عملکرد بطن چپ و نسبت (pf) pao2/fio2 کمتر یا مساوی 200 برای ards و کمتر یا مساوی 300 برای ali؛ که مورد اخیر نیازمند نمونه گیری تهاجمی خون شریانی هست. spo2 که توسط دستگاه پالس اکسی متری اندازه گیری می شود و محاسبه نسبت spo2/fio2 (sf) را شاید بتوان یک آلترنا...
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...
the effect of positive end expiratory pressure (peep) on the hepatic elimination of low to moderate extraction ratio drugs has not been clearly defined. we prospectively investigated the effect of peep on the clearance of theophylline in 30 (20 males and 10 females) intubated critically ill adult patients with acute lung injury/acute respiratory distress syndrome (ali/ards). the mean (±sd) age ...
BACKGROUND Ventilator practices in patients at risk for acute lung injury (ALI) and ARDS are unclear. We examined factors associated with choice of set tidal volumes (VT), and whether VT < 8 mL/kg predicted body weight (PBW) relates to the development of ALI/ARDS. METHODS We performed a secondary analysis of a multicenter cohort of adult subjects at risk of lung injury with and without ALI/AR...
The recently reported differences between pulmonary and extrapulmonary acute respiratory distress syndromes (ARDS(p), ARDS(exp)) are the main reasons of scientific discussion on potential differences in the effects of current ventilatory strategies. The aim of this study is to assess whether the presence of ARDS(p) or ARDS(exp) can differently affect the beneficial effects of high-frequency osc...
This study assessed whether combining adipose-derived mesenchymal stem cells (ADMSC) with preactivated, disaggregated shape-changed platelets (PreD-SCP) was superior to either therapy alone for protecting rat lung from acute respiratory distress syndrome (ARDS) complicated by sepsis. ARDS and sepsis were induced through 100% oxygen inhalation and peritoneal administration of 1.5 mg/kg lipopolys...
