Efeito De Diferentes Níveis De Pressão Positiva Continua Sobre a Depuração Pulmonar Do 99mtc-Dtpa

Abstract

O não produziu alteração na taxa de depuração. Backgound and Objectives:Positive airway pressure continues (CPAP) produces significant hemodynamic changes that may influence the variability of breathing pattern and heart rate, acting as an additional therapy to prevent atelectasis and to combat hypoxia. The rate of inhaled 99m Technetium-diethylenetriaminepentaacetic acid ( 99m Tc-DTPA), along with changes in the lung epithelium cause an increase in the rate of clearance of this compound. The aim of this study was evaluate the pulmonary clearance rate of 99m Technetium-Diethylenetriaminepentaacetic acid ( 99m Tc-DTPA) through the use of different levels of CPAP. Methods: It was a quasi-experimental study involving 17 healthy individuals with normal lung functional. Tc-DTPA clearance moreover, 10 cmH 2 O did not alter its clearance rate. RESUMO ABSTRACT
