Visualisation of Time-Variant Respiratory System Elastance in ARDS Models.
Model-based mechanical ventilation (MV) can be used to characterise patient-specific condition and response to MV. This paper presents a novel method to visualise respiratory mechanics during MV of patients suffering from acute respiratory distress syndrome. The single compartment lung model is extended to monitor time-varying respiratory system elastance within each breathing cycle. Monitoring...
متن کاملVisualisation of time-varying respiratory system elastance in experimental ARDS animal models
BACKGROUND Patients with acute respiratory distress syndrome (ARDS) risk lung collapse, severely altering the breath-to-breath respiratory mechanics. Model-based estimation of respiratory mechanics characterising patient-specific condition and response to treatment may be used to guide mechanical ventilation (MV). This study presents a model-based approach to monitor time-varying patient-ventil...
متن کاملKinetics of respiratory system elastance after airway challenge in dogs.
We compared the time courses of lung mechanical changes with intravenous (iv) injection vs. aerosol administration of histamine, methacholine, and ACh in dogs. We interpret these results in terms of a spring-and-dashpot model of airway smooth muscle receiving activation via a tissue compartment when agonist is delivered by the iv route and through an additional airway wall compartment when it i...
متن کاملTime-Varying Respiratory Elastance for Spontaneously Breathing Patients
Respiratory mechanics models can be used to optimise patient-specific mechanical ventilation (MV), but are limited to fully sedated MV patients who are not spontaneously breathing. This research presents a non-invasive model-based method to determine respiratory mechanics of spontaneously breathing MV patients. Patient-specific respiratory mechanics of 22 spontaneously breathing patients are de...
متن کاملTime-Varying Respiratory System Elastance: A Physiological Model for Patients Who Are Spontaneously Breathing
BACKGROUND Respiratory mechanics models can aid in optimising patient-specific mechanical ventilation (MV), but the applications are limited to fully sedated MV patients who have little or no spontaneously breathing efforts. This research presents a time-varying elastance (E(drs)) model that can be used in spontaneously breathing patients to determine their respiratory mechanics. METHODS A ti...
