Ventilator manufacturers and the respiratory care academic community have not yet adopted a standardized system for classifying and describing ventilation modes. As a result, there is enough confusion that potential sales, education, and patient care are all put at risk. This proposal summarizes a ventilator-mode classification scheme and complete lexicon(More)
A wide variety of ventilators and modes can be used to deliver noninvasive ventilation (NIV). To navigate successfully through the many options, the clinician must first have a clear understanding of the goals of mechanical ventilation: namely, safety, comfort, and timely liberation. Examining the specific objectives associated with these goals, we can(More)
UNLABELLED Tidal volume (VT) measurement during pressure control (PC) ventilation with preset inspiratory time may produce errors due to patient inspiratory effort. We evaluated VT error in 3 common ICU ventilators. METHODS Simulated patient: 60kg adult with ARDS using IngMar Medical ASL 5000 having moderate inspiratory effort. Ventilators evaluated:(More)
High-frequency ventilation got its start in the United States from a paper by Dr Mirosolav Klain, an anesthe-siologist who described a high-frequency jet ventilator (HFJV) 1 he built using a fluidic control circuit purchased as a demonstration kit from Corning Glass Works. 2 Based on his description of the circuit, we built an HFJV and humidification system(More)
Background. There are modes of mechanical ventilation that can select ventilator settings with computer controlled algorithms (targeting schemes). Two examples are adaptive support ventilation (ASV) and mid-frequency ventilation (MFV). We studied how different clinician-chosen ventilator settings are from these computer algorithms under different scenarios.(More)
BACKGROUND Adaptive pressure control is a mode of mechanical ventilation where inflation pressure is adjusted by the ventilator to achieve a target tidal volume (VT). This means that as patient effort increases, inflation pressure is reduced, which may or may not be clinically appropriate. The purpose of this study was to evaluate the relationship between(More)
