By use of logistic regression analysis, mechanical ventilation, male gender, and length of stay were identified as significant predictors for the occurrence of (near) incidents.
We used a logistic regression model with protective ventilation as the dependent variable and all of the covariates noted as independent variables.
The slope of the linear regression line of minute ventilation versus SaO2 or CO2-et indicates the chemoreflex sensitivity to hypoxia or hypercapnia, respectively.
We used a mixed effects logistic regression model, with protective ventilation as the dependent variable and the covariates used in the primary analysis as fixed effects.
5 7 Peak oxygen uptake (peak VO2) or the regression slope relating minute ventilation to carbon dioxide output (VE/VCO2 slope) has been used to identify patients with either ischaemic or non-ischaemic cardiomyopathy at high risk for cardiac death or in need of cardiac transplantation.
In order to assess for trends in survival over time, before and after the introduction of the protective ventilation, logistic regression analyses was performed for each time period with hospital survival as the dependent variable and calendar year as the continuous explanatory variable.
cTnT levels were significant in multivariate regression independent of age and ventilation but did not reach significance (P = 0.06) in a multivariate analysis that included the APACHE II score.
To illustrate the use of average coefficients compared to using individual regression coefficients, we calculated minute ventilation values using the mean slopes and intercepts, and using the mean heart rates of the participants during the bicycle rides, see table 5.
According to logistic regression analysis, duration of mechanical ventilation for 7 days or more, prior antibiotic use, and prior use of broad-spectrum antibiotics (third-generation cephalosporins, fluoroquinolones, and/or imipenem) were associated with the development of ventilator-associated pneumonia due to antibiotic-resistant pathogens.
The correlation between absolute humidity and minute ventilation was analyzed by regression.
