Fisiología respiratoria: contribución de la estructura de la vía aérea y el pulmón a la función del aparato respiratorio

Conocer la estructura del sistema respiratorio es fundamental para comprender cómo realiza sus funciones, desde la principal, el intercambio gaseoso, hasta otras funciones no respiratorias tales como el equilibrio ácido-base, fonación, defensa pulmonar, metab...

Effect of intraoperative lung-protective mechanical ventilation on pulmonary oxygenation function and postoperative pulmonary complications after laparoscopic radical gastrectomy

Braz. j. med. biol. res; 52 (6), 2019
This study aimed to observe the effects of lung-protective ventilation (LPV) on oxygenation index (OI) and postoperative pulmonary complications (PPCs) after laparoscopic radical gastrectomy in middle-aged and elderly patients. A total of 120 patients who were scheduled to undergo laparoscopic radical ga...

Analysis of different levels of positive end-expiratory pressure during lung retrieval for transplantation: an experimental study

Braz. j. med. biol. res; 52 (7), 2019
Atelectasis and inadequate oxygenation in lung donors is a common problem during the retrieval of these organs. Nevertheless, the use of high positive end-expiratory pressure (PEEP) is not habitual during procedures of lung retrieval. Twenty-one Sprague-Dawley male consanguineous rats were used in the st...

Avaliação do tamanho do pulmão em cães: a capacidade inspiratória define o volume corrente

RESUMO Objetivo: Avaliar uma nova abordagem fisiológica para a determinação do volume corrente em ventilação mecânica, de acordo com a capacidade inspiratória, e determinar se isso resulta em medidas mecânicas e de troca gasosa adequadas em cães saudáveis e em estado crítico. Métodos: Inclu...

Cardiorespiratory and metabolic determinants during moderate and high resistance exercise intensities until exhaustion using dynamic leg press: comparison with critical load

Braz. j. med. biol. res; 51 (11), 2018
The objective of this study was to assess cardiovascular, respiratory, and metabolic responses during a commonly used dynamic leg press resistance exercise until exhaustion (TEx) at different intensities and compare with critical load (CL). This was a prospective, cross-sectional, controlled, and crossov...

Effect of different levels of peep on oxygenation during non-invasive ventilation in patients submitted to cabg surgery: randomized clinical trial

Abstract Introduction: During and after coronary artery bypass grafting, a decline in multifactor lung function is observed. Due to this fact, some patients may benefit from non-invasive ventilation after extubation targeting lung expansion and consequently improved oxygenation. Objective: To test the ...

Pendelluft diagnosed from ventilator weaning indexes obtained through bioelectrical impedance tomography: a case report

Säo Paulo med. j; 135 (3), 2017
ABSTRACT CONTEXT: Today, through major technological advances in diagnostic resources within medicine, evaluation and monitoring of clinical parameters at the patient's bedside in intensive care units (ICUs) has become possible. CASE REPORT: This case report presents results and interpretations from ...

Alterações da mecânica ventilatória durante a fisioterapia respiratória em pacientes ventilados mecanicamente

RESUMO Objetivo: Avaliar as alterações da mecânica ventilatória e da hemodinâmica que ocorrem em pacientes dependentes de ventilação mecânica submetidos a um protocolo padrão de fisioterapia respiratória. Métodos: Estudo experimental e prospectivo realizado em duas unidades de tratamento inten...
