13. Decreases in procalcitonin and C-reactive protein are strong predictors of survival in ventilator-associated pneumonia
Introduction This study sought to assess the prognostic value of the kinetics of procalcitonin (PCT), C-reactive protein (CRP) and clinical scores (clinical pulmonary infection score (CPIS), Sequential Organ Failure Assessment (SOFA)) in the outcome of ventilator-associated pneumonia (VAP) at an early time point, when adequacy of antimicrobial treatment is e

14. 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

15. Effects of noninvasive ventilation with continuous positive pressure on the airways of oncologic patients / Efeito da ventilação não invasiva com pressão positiva contínua nas vias aéreas de pacientes oncológicos
INTRODUCTION: Respiratory failure is a common situation among cancer patients leading to high rates of mortality. Noninvasive ventilation (NIV) can help its management, but its effects are still unknown regarding the pulmonary defense mechanisms. OBJECTIVES: Observe the effect of NIV with facial mask using a flow generator with continuous positive pressure (

16. Effects of recruitment maneuver during expiration and inspiration analyzed by thoracic CT scan in patients with acute lung injury and acute respiratory distress syndrome / Efeitos da manobra de recrutamento alveolar nas fases inspiratória e expiratória na tomografia computadorizada de tórax em pacientes com lesão pulmonar aguda ou síndrome do desconforto respiratório agudo
The goal of Maximal Recruitment Strategy (MRS) guided by thoracic CT scan is to minimize alveolar collapse and the mechanisms of ventilator induced lung injury (VILI). The objectives of this study were to compare by quantitative analyzes of CT scan image of the lungs obtained during MRS of patients with ARDS, the following parameters: collapse, overdistensio

17. A influencia da traqueostomia no tempo de ventilação mecanica, internação hospitalar e incidencia de pneumonia em pacientes com traumatismo craniencefalico / The influence of tracheostomy in the mechanical ventilation time, incidence of pulmonary infection and hospital length of stay in patients with traumatic brain injury
Tracheostomy has been performed frequently in ventilator-dependent patients in intensive care unit (ICU). Some authors believe that early tracheostomy can reduce mechanical ventilation (MV) time and can provide other associated benefits. However, its influence on weaning from MV is not clear in pacients with traumatic brain injury (TBI). The aim of this stud

18. 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

19. Efeito imediato da pressão positiva continua nas vias aereas não invasiva no volume pulmonar expiratorio final de pacientes com doença pulmonar obstrutiva cronica / Immediate effects of non invasive continuous positive airway pressure in end-expiratory lung volume in chronic obstructive pulmonary disease patients
Bachground: Flow limitation and dynamic hyperinflation are common findings in COPD patients. Inspiratory capacity (IC) has been proposed as a simple method to assess changes in end-expiratory lung volume (EEL V) and lung hyperinflation. However, few studies verified if the application of continuous positive airway pressure (CP AP) could decrease lung hyperin

20. Tomographic evaluation of the small airways in the interstitial lung diseases / Avaliação tomográfica do acometimento das pequenas vias aéreas nas doenças intersticiais do pulmão
The pathogenesis of idiophatic pulmonary fibrosis (IPF), the most common form of idiopathic interstitial pneumonias, is not completely understood. It is related to a type I pneumocyte injury with loss of basement membrane integrity and failure of normal re-epithelialization and re-endothelialization leading to fibroblast proliferation and extra cellular matr

21. Airway clearance techniques in patients submitted to mechanical ventilation: A hemodynamic, gas exchange, respiratory mechanics and bronquial sputum study / Estudo do comportamento hemodinâmico, da troca gasosa, da mecânica respiratória e da análise do muco brônquico na aplicação de técnicas de remoção de secreção brônquica em pacientes sob ventilação mecânica
INTRODUCTION: Tracheal suction (TS) is a routine procedure in patients submitted to mechanical ventilation. In association, the bag-squeezing (BS) technique is described as a manual hyperinflation associated to a manually assisted coughing followed by TS. This technique might present few limitations as its mechanical ventilator disconnection and poor control

22. Efeito imediato da pressão positiva continua nas vias aeres não invasiva no volume pulmonar expiratorio final de pacientes com doença pulmonar obstrutiva cronica / Immediate effects of non invasive continuous positive airway pressure in end-expiratory lung volume in chronic obstructive pulmonary disease patients
Introdução: Limitação ao fluxo e hiperinsuflação dinâmica são fteqüentemente observadas em pacientes com DPOC. A capacidade inspiratória (CI) tem sido sugerida como um método simples para verificar as alterações no volume pulmonar expiratório final e hiperinsuflação pulmonar. Entretanto, poucos estudos verificaram se a aplicação de pressão

23. METROLOGICAL RELIABILITY OF LUNG VENTILATORS / CONFIABILIDADE METROLÓGICA DE VENTILADORES PULMONARES
The present Masters dissertation evaluates the metrological reliability of pulmonary ventilators, also known as mechanical ventilators. Pulmonary ventilators are electromedical equipment (EEM). The absence of metrological reliability of a pulmonary ventilator may result in dangerous consequences, according to its classification by the potential risk to the h

24. 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
