El espacio muerto (VD/VT) como predictor de éxito en la extubación de pacientes postquirúrgicos de cirugía cardiovascular pediátrica

Med. infant; 27 (2), 2020
Introducción: La ventilación mecánica (VM) forma parte de la recuperación postoperatoria (PO) de niños con cirugía de cardiopatía congénita, pero su uso no está exento de riesgos. El fracaso de extubación (FE) se ha asociado con internaciones prolongadas, aumento de complicaciones y mortalidad....

Comparison of pressure-controlled volume-guaranteed ventilation and volume-controlled ventilation in obese patients during gynecologic laparoscopic surgery in the Trendelenburg position

Rev. bras. anestesiol; 69 (6), 2019
Abstract Background and objectives: The aim of this study was to investigate the efficacy of the pressure-controlled, volume-guaranteed (PCV-VG) and volume-controlled ventilation (VCV) modes for maintaining adequate airway pressures, lung compliance and oxygenation in obese patients undergoing laparosco...

Respiratory evaluation through volumetric capnography among grade III obese and eutrophic individuals: a comparative study

Säo Paulo med. j; 137 (2), 2019
ABSTRACT BACKGROUND: Excess trunk body fat in obese individuals influences respiratory physiological function. The aims of this study were to compare volumetric capnography findings (VCap) between severely obese patients and normal-weight subjects and to assess whether there is any association between ...

Evaluation of respiratory dynamics by volumetric capnography during submaximal exercise protocol of six minutes on treadmill in cystic fibrosis patients

J. pediatr. (Rio J.); 95 (1), 2019
Abstract Objectives: Volumetric capnography provides the standard CO2 elimination by the volume expired per respiratory cycle and is a measure to assess pulmonary involvement. Thus, the objective of this study was to evaluate the respiratory dynamics of healthy control subjects and those with cystic fib...

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...

Evaluation of volume responsiveness by pulse pressure variability and inferior vena cava dispensability index at different tidal volumes by mechanical ventilation

Braz. j. med. biol. res; 52 (9), 2019
This study investigated the effects of tidal volume (TV) on the diagnostic value of pulse pressure variation (PPV) and the inferior vena cava dispensability index (IVC-DI) for volume responsiveness during mechanical ventilation. In patients undergoing elective surgery with mechanical ventilation, differe...

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...

Influencia de la caja torácica en el monitoreo de la mecánica respiratoria en síndrome de distrés respiratorio agudo

RESUMEN La mecánica del sistema respiratorio depende de las características del pulmón, la caja torácica y su interacción. En pacientes con síndrome de distrés respiratorio agudo bajo ventilación mecánica el monitoreo de la presión meseta en la vía aérea es fundamental debido a su valor pron�...

Aplicabilidade das variações respiratórias do volume sistólico e seus substitutos para predição da responsividade dinâmica a fluidos em pacientes críticos: uma revisão sistemática sobre a prevalência das condições requeridas

RESUMO Objetivo: Avaliar os dados publicados em relação à prevalência das condições requeridas para avaliação apropriada em pacientes críticos. Métodos: Foram realizadas buscas nas bases de dados MEDLINE, Scopus e Web of Science para identificar estudos que discutiam a prevalência de condiç...

It is impossible to know the way if we do not know where to start: tidal volume, driving pressure, and positive end-expiratory pressure
