Evaluation of an active humidification system for inspired gas.
Clin Exp Otorhinolaryngol
March 2015
Objectives: The effectiveness of the active humidification systems (AHS) in patients already weaned from mechanical ventilation and with an artificial airway has not been very well described. The objective of this study was to evaluate the performance of an AHS in chronically tracheostomized and spontaneously breathing patients.
Methods: Measurements were quantified at three levels of temperature (T°) of the AHS: level I, low; level II, middle; and level III, high and at different flow levels (20 to 60 L/minute).
The aim of this study was to describe the population admitted to a weaning center (WC) to receive invasive mechanical ventilation (MV), analyze their evolution and identify weaning failure predictors. The medical records of 763 patients admitted to the respiratory care service in the period between May 2005 and January 2012 were reviewed; 372 were selected among 415 tracheotomized and mechanically ventilated. Different variables were analyzed as weaning failure predictors.

- The study focuses on cuff pressure (CP) variations in tracheostomized patients who are not on mechanical ventilation, which is an area that has been under-researched.
- An experimental setup tested the performance of pressure gauges on different tracheostomy tubes, while a clinical setup measured CP variations over 6 days in 35 stable patients.
- Findings revealed significant differences in cuff pressures across tube brands and types, with a notable variability in measurements, indicating that more frequent monitoring of CP in these patients is necessary.
