Mechanical ventilators display detailed waveforms which contain a wealth of clinically relevant information. Although much has been written about interpretation of waveforms and patient-ventilator interactions, variability remains on the nomenclature (multiple and ambiguous terms) and waveform interpretation. ⋯ In addition, there is no widely accepted systematic method to read ventilator waveforms. We propose a standardized nomenclature and taxonomy along with a method to interpret mechanical ventilator displayed waveforms.

Randomized Controlled Trial Multicenter Study
Comparison of Two Extubation Techniques in Critically Ill Adult Subjects: The ExtubAR Randomized Clinical Trial.
Two orotracheal extubation techniques are described in the literature: the traditional technique and the positive-pressure technique. Although prior studies reported better clinical outcomes with the positive-pressure extubation technique, its superiority has not been extensively studied yet. This study was to determine whether the positive-pressure orotracheal extubation technique, compared with the traditional orotracheal extubation technique, reduces the incidence of major postextubation complications (up to 60 min) in critically ill adult subjects. ⋯ Despite the trend toward the positive-pressure group, no statistically significant differences were observed. Our findings agree with the literature in that positive-pressure extubation is a safe procedure; therefore, both techniques may be used during extubation in critically ill adult patients.

Although noninvasive ventilation (NIV) is administered to manage respiratory failure due to various causes, safety and effectiveness issues associated with the use of NIV masks have been reported. The present article aims to provide health professionals with a comprehensive review of the ergonomic considerations of NIV masks in terms of design, evaluation, and personalization. ⋯ The comprehensive information presented in this review provides ergonomic perspectives to identify and prevent safety and usability problems associated with the use of NIV masks. Ergonomic improvement and personalization are important goals in order to facilitate the success of NIV treatment.
