Relationship of uni-lung percentage of blood flow to uni-lung percentage of carbon dioxide production in normal and unilateral injured lungs in a canine model
نویسندگان
چکیده
It is difficult clinically to measure relative blood flow to each lung. We hypothesized that uni-lung % blood flow is linearly related to % carbon dioxide excretion (VCO2). In a canine model of acute unilateral lung injury, we measured uni-lung flow with ultrasonic flow-probes, and uni-lung VCO2 with two separate metabolic monitors utilizing split lung ventilation following thoracotomy. Relative flow to the lungs was altered by inflating a pulmonary artery catheter balloon in one of the lungs under conditions of norCase Report

Background and Objective: Natural killer T like (NKT) cells are a population of T cells that show NK cells features. These cells in addition to administrative actions, have an important role in the regulation of immune responses. The role of these cells in people exposed to sulfur mustard (SM) are not well known. The aim of this study was to determine the percentage of NKT cells in the peripher...
متن کاملMathematical Modeling of Carbon Dioxide Removal from the CO2/CH4 Gas Mixture Using Amines and Blend of Amines in Polypropylene: A Comparison between Hollow Fiber Membrane Contactor and Other Membranes
In this work, a mathematical model is established to describe the removal of CO2 from gaseous mixtures including CH4 and CO2 in a polypropylene hollow fiber membrane contactor in the presence of conventional absorbents such as monoethanolamine (MEA), methyldiethanolamine (MDEA), and a blend of them. Modeling was performed in axial and radial directions under the fully-wet condition for counterc...
متن کاملTime course and pattern of pulmonary flow distribution following unilateral airway occlusion in sheep.
1. Unilateral bronchial occlusion causes ipsilateral hypoxic pulmonary vasoconstriction, which shifts blood flow towards the other lung. We studied the time course of flow diversion following acute bronchial occlusion, and the temporal effect of the latter on blood gases and vertical distribution of blood flow within the two lungs. 2. Serial infusion of radioactive or fluorescent microspheres w...

Introduction: Pulmonary involvement secondary to Systemic Sclerosis (SSc) is the major cause of morbidity and mortality in SSc patients. We designed this study to determine the correlation of important lung function parameters with lung High Resolution CT (HRCT) scan findings. Materials and Methods: Thirty–two consecutive diffuse SSc patients with pulmonary fibrosis were enrolled in this cross...
