Closed-loop control of airway occlusion pressure at 0.1 second (P0.1) applied to pressure-support ventilation: algorithm and application in intubated patients

, 1996
Airway occlusion pressure at 0.1 sec (P0.1) is an index of respiratory center output. During pressure-support ventilation, P0.1 correlates with the mechanical output of the inspiratory muscles and has an inverse relationship with the amount of pressure ...

Parâmetros preditivos para o desmame da ventilação mecânica Predictive parameters for weaning from mechanical ventilation

Jornal Brasileiro de Pneumologia, 2011
A utilização de parâmetros preditivos para o desmame da ventilação mecânica é um tema de grande polêmica, com estudos divergindo sobre esse assunto. Independentemente da utilização desses parâmetros preditivos, o teste de respiração espontânea (TRE) é ...

Drive respiratório anormal na doença vibroacústica Abnormal respiratory drive in vibroacoustic disease

Revista Portuguesa de Pneumologia, 2006
Enquadramento: As alterações do sistema nervoso central em trabalhadores expostos a ruído de baixa frequência (RBF, 60%). Conclusões:Na resposta reflexa ao acréscimo de PCO2, os quimio-receptores centrais são responsáveis por 70% do estímulo ventilatório.

High Airway Occlusion Pressure Is Associated with Dyspnea and Increased Mortality in Critically Ill Mechanically Ventilated Patients

International audienceRationale: Airway occlusion pressure at 100 ms (P0.1) reflects central respiratory drive.Objectives: We aimed to assess factors associated with P0.1 and whether an abnormally low or high P0.1 value is associated with higher ...

Impacto do uso de um vacuômetro digital e da válvula unidirecional sobre índices respiratórios preditores de desmame ventilatório

, 2011
Objetivo: Avaliar a pressão inspiratória máxima, obtida por um vacuômetro digital com o método de válvula unidirecional expiratória (PImáxUV), como preditor de desmame ventilatório e comparar seu desempenho com a pressão de oclusão traqueal em 100 ms (P0.

Definition of new referential values of maximum inspiratory and expiratory pressures and P0.1 values in normal population aged 14 - 15 years

, 2014
The aim of this study is definition reference values including reference equations for parameters PImax, PEmax and P0.1 of the normal Czech population aged 14-15 years. 102 subjects were examined for this purpose (55 boys and 47 girls).

Response to external inspiratory resistive loading and bronchospasm in anesthetized dogs

, 1982
Mouth occlusion pressure (P0.1) and breathing-pattern responses to external inspiratory resistive loading and methacholine chloride-induced bronchospasm were assessed in six dogs under pentobarbital sodium anesthesia.

Airway Occlusion Pressure As an Estimate of Respiratory Drive and Inspiratory Effort during Assisted Ventilation.

, 2020
Rationale: Monitoring and controlling respiratory drive and effort may help to minimize lung and diaphragm injury. Airway occlusion pressure (P0.1) is a noninvasive measure of respiratory drive.Objectives: To determine 1) the validity of "ventilator" P0 ...

Definition of new referential values of maximum inspiratory and expiratory pressures and P0.1 values in normal population of the 16 - to - 17 age range

, 2014
The purpose of this thesis is to define norms for inspiratory (Pimax) and expiratory (Pemax) pressures and mouth occlusion pressure (P0.1) in healthy white population of the 16-17 age group in the Czech Republic, specifically the capital city of Prague ...

Effect of inhaled histamine on occlusion pressure and breathing pattern in asthmatic patients

, 1987
In animals, histamine inhalation is known to increase either respiratory frequency or respiratory drive by stimulation of airway vagal sensitive endings. However, it is not well known whether these changes are concomitant in man.
