A variable waveform ventilator.
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....
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 کاملVentilator with a capnograph smart sensors
Today, the world has witnessed increasing development in various fields, including industry and medicine. One of the best ways to achieve these objectives is the integration of different sciences including electronics, robotics and medicine. Ventilator set that provides respiratory function for patients get smarter and more capable than older generations, during mechanical ventilation to preven...
متن کاملManagement of bronchopleural fistula with a variable-resistance valve and a single ventilator.
Independent lung ventilation with two ventilators is sometimes used in the management of bronchopleural fistula (BPF). We describe a patient in whom gas flow through a large BPF was initially reduced, and subsequently eliminated, during differential lung ventilation using a single ventilator and a variable-resistance valve attached to one lumen of a bifurcated endotracheal tube.
متن کاملA Closed-loop Multimode Variable Bit Rate Characteristic Waveform Interpolation Coder
A variable bit rate characteristic waveform interpolation (VBR-CWI) speech codec with about 1.86kbps average bit rate which combines closed-loop multimode techniques is presented in this paper. Each kind of characteristic waveform (CW) surface is regarded as only rapidly evolving waveforms (REWs), only slowly evolving waveforms (SEWs) or mixed REWs plus SEWs in different cases of CWs evolving p...
