Efficacy 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...

OBJECTIVES The value of visual inspection of ventilator waveforms in detecting patient-ventilator asynchronies in the intensive care unit has never been systematically evaluated. This study aims to assess intensive care unit physicians' ability to identify patient-ventilator asynchronies through ventilator waveforms. DESIGN Prospective observational study. SETTING Intensive care unit of a U...
متن کاملUsing ventilator graphics to identify patient-ventilator asynchrony.
Patient-ventilator interaction can be described as the relationship between 2 respiratory pumps: (1) the patient's pulmonary system, which is controlled by the neuromuscular system and influenced by the mechanical characteristics of the lungs and thorax, and (2) the ventilator, which is controlled by the ventilator settings and the function of the flow valve. When the 2 pumps function in synchr...
متن کاملPatient–ventilator asynchrony during conventional mechanical ventilation in children
BACKGROUND We aimed (1) to describe the characteristics of patient-ventilator asynchrony in a population of critically ill children, (2) to describe the risk factors associated with patient-ventilator asynchrony, and (3) to evaluate the association between patient-ventilator asynchrony and ventilator-free days at day 28. METHODS In this single-center prospective study, consecutive children ad...

There have been a number of studies of the physiological effects of different tracheal pressure wave patterns in patients requiring artificial ventilation with intermittent positive pressure (IPPV) (Werko, 1947; Cournand et al., 1948; Maloney et al., 1953; Watson, 1962a, b; Bergman, 1963, 1967; Grenvik, 1966; Auchinloss and Gilbert, 1967; Robinson, 1967; Herzog and Norlander, 1968; Adams et al....
