13. Resposta cardiovascular ao exercício em pacientes portadores de hipertensão arterial pulmonar / Cardiovascular response to exercise in patients with pulmonary arterial hypertension
The proper understanding of the cardiovascular response to exercise has a central role in the management and treatment of patients with pulmonary arterial hypertension (PAH). However, data concerning the evolution of pulmonary vascular mechanics and right ventricular adaptation to effort are scarce. The aim of this study is characterize the cardiovascular re

14. A sigmoidal fit for pressure-volume curves of idiopathic pulmonary fibrosis patients on mechanical ventilation: clinical implications
OBJECTIVE: Respiratory pressure-volume curves fitted to exponential equations have been used to assess disease severity and prognosis in spontaneously breathing patients with idiopathic pulmonary fibrosis. Sigmoidal equations have been used to fit pressure-volume curves for mechanically ventilated patients but not for idiopathic pulmonary fibrosis patients.

15. Fatores que influenciam a técnica de hiperinsuflação manual com balão auto-inflável neonatal e pediátrico / Factors affecting manual hyperinflação technique with neonatal and pediatric self-inflating bags
Background: Self-inflating bag (BAI) is the device used to manual ventilate during manual hyperinflation (HM) technique. Despite the BAI being widely used, there is limited information available on their physical characteristics and ventilatory outcomes. The goal of this study was to evaluate the performance of three brands of neonatal and pediatric SIB duri

16. Comportamento da mecânica ventilatória durante a realização de um atendimento de fisioterapia respiratória
Question: Can Respiratory therapy alter the lung mechanics in patients with invasive mechanical ventilation? The data available in the literature remain controversial. This study aims to assess the changes of pulmonary mechanics in patients with invasive mechanical ventilation, comparing hemodynamic and ventilatory parameters one hour prior to application of

17. Effects of pressure controlled ventilation and volume controlled ventilation on pulmonary function in cardiac surgery patients with cardiopulmonary bypass / Efeitos do suporte ventilatorio com pressão controlada e volume controlado na função pulmonar dos pacientes submetidos a cirurgia cardiaca com circulação extra-corporea
Postoperative lung injury after cardiac surgery with cardiopulmonary bypass (CPB) is usually related to the systemic inflammatory response syndrome (SIRS). Many patients undergoing this procedure develop acute lung injury (ALI), and some of them acute respiratory distress syndrome (ARDS). Many factors can be directly or indirectly related to the postoperativ

18. Correlação da composição corporal com a função pulmonar e com a força muscular respiratória em indivíduos com a Trissomia 21 no Distrito Federal
Introduction: Overweight and respiratory malfunctions are frequently found in Trysomy 21 bearers. Such disturbances are potentially able to lead to conditions which endanger the quality of life of affected individuals, thus aggravating their physical health and excluding them from social interaction. Purpose: the purpose of this academic essay was to investi

19. Efeito da obesidade sobre a forÃa dos mÃsculos respiratÃrios e centro respiratÃrio
Background: The obesity affects many organs and systems of human body, prejudicing vital functions by immunologic, circulatory, hormonal and respiratory functions. On the respiratory system, obesity results in a reduction of lung volumes and flows. Also take a reduction on the respiratory compliance and an increment on the total respiratory resistance. Metho

20. Effects of open lung concept following ARDSNet ventilatory strategy in patients with early acute lung injury (ALI) / acute respiratory distress syndrome (ARDS) / Avaliação de estratégia ventilatória seqüencial em pacientes com lesão pulmonar aguda (LPA) / síndrome do desconforto respiratório agudo (SDRA)
Low tidal volumes are associated with a reduction in mortality in ALI / ARDS. Nevertheless, the application of recruitment maneuvers and high levels of PEEP are still controversial. The aim of this study was to compare the ARDSnet protocol with a strategy based on Open Lung Concept (OLC), applied in a sequential way, in terms of pulmonary function, computed

21. Efeitos da adição de polietilenoglicol ao surfactante exógeno no tratamento da síndrome de aspiração de mecônio em coelhos recém-nascidos / Effects of polyethylene glycol added to exogenous surfactant for meconium aspiration syndrome treatment in newborn rabbits
Meconium is known to be a potent inactivator of pulmonary surfactant, and exogenous surfactant treatment for meconium aspiration syndrome failed to decrease mortality. A number of studies have shown, in vitro, that the addition of polymers such as polyethylene glycol (PEG) to the surfactant maintains good surface activity in the presence of meconium. In the

22. Repercussões nos gases sanguíneos de recém-nascidos prematuros com síndrome do desconforto respiratório e sob ventilação mecânica convencional após ajuste no tempo inspiratório em função da constante de tempo
Were evaluated twenty-five neonates with less than 2000 grams of birth weight and gestational age lesser than thirty-five weeks, diagnosed with respiratory distress syndrome, on conventional mechanical ventilation, treated with exogenous surfactant and were at first seventy-two hours of life. With the use of a pneumotachometer associated to ventilator were p

23. Comportamento Pulmonar nos Portadores de Cardiopatias Congênitas com Hiperfluxo Pulmonar após Tratamento Cirúrgico.
Avaliar o comportamento da complacência pulmonar e resistência da via aérea nos pacientes portadores de cardiopatias congênitas com hiperfluxo pulmonar submetidos a tratamento cirúrgico com auxílio de circulação extracorpórea. Método: Trinta e cinco pacientes foram avaliados com medidas de complacência estática e resistência da via aérea em qua

24. Alternative parameters for echocardiographic assessment of fetal diastolic function
Alternative methods to assess ventricular diastolic function in the fetus are proposed. Fetal myocardial hypertrophy in maternal diabetes was used as a model of decreased left ventricular compliance (LVC), and fetal respiratory movements as a model of increased LVC. Comparison of three groups of fetuses showed that, in 10 fetuses of diabetic mothers (FDM) wi
