Objective Evaluation of Patient–ventilator Interactions during Noninvasive Ventilation (niv)
WINNING ABSTRACT: The success of NIV depends on patient–ventilator interactions. These interactions are evaluated with the subjective comfort score which is not always reliable. An objective evaluation is thus required. To evaluate these interactions, we use a statistical measure of the variability of a physiological signal, i.e the Shannon entropy. Our purpose is to show whether estimating Sha...
متن کاملPatient-ventilator interaction during noninvasive ventilation.
There is arguably more evidence to support the use of noninvasive ventilation (NIV) than any other practice related to the care of patients with acute respiratory failure. Despite this strong evidence base, NIV seems to be under-utilized and the failure rate (need for intubation) may be as high as 40%. Some of these failures potentially relate to asynchrony, although the relationship between as...
متن کاملPatient-Ventilator Interaction During Noninvasive Ventilation in Simulated COPD.
BACKGROUND During noninvasive ventilation (NIV) of COPD patients, delayed off-cycling of pressure support can cause patient ventilator mismatch and NIV failure. This systematic experimental study analyzes the effects of varying cycling criteria on patient-ventilator interaction. METHODS A lung simulator with COPD settings was connected to an ICU ventilator via helmet or face mask. Cycling was...
متن کاملEfficacy of ventilator waveform observation for detection of patient–ventilator asynchrony during NIV: a multicentre study
The objective of this study was to assess ability to identify asynchronies during noninvasive ventilation (NIV) through ventilator waveforms according to experience and interface, and to ascertain the influence of breathing pattern and respiratory drive on sensitivity and prevalence of asynchronies. 35 expert and 35 nonexpert physicians evaluated 40 5-min NIV reports displaying flow-time and ai...
متن کاملGlobal models for patient-ventilator interactions in noninvasive ventilation with asynchronies
Noninvasive ventilation is a clinical procedure that enables patients with chronic respiratory failure to reduce the work of breathing and to improve blood oxygenation. In order to attain such goals, the ventilation support is expected to be phase synchronized with the patient spontaneous breathing. Unfortunately, asynchrony events are not rare. In order to provide more effective ventilation sc...
