Respiratory mechanics studied by forced oscillations during artificial ventilation.
Potential advantages of the forced oscillation technique over other methods for monitoring total respiratory mechanics during artificial ventilation are that it does not require patient relaxation, and that additional information may be derived from the frequency dependence of the real (Re) and imaginary (Im) parts of respiratory impedance. We wanted to assess feasibility and usefulness of the ...
متن کاملEnd-inspiratory pause prolongation in acute respiratory distress syndrome patients: effects on gas exchange and mechanics
BACKGROUND End-inspiratory pause (EIP) prolongation decreases dead space-to-tidal volume ratio (Vd/Vt) and PaCO2. We do not know the physiological benefits of this approach to improve respiratory system mechanics in acute respiratory distress syndrome (ARDS) patients when mild hypercapnia is of no concern. METHODS The investigation was conducted in an intensive care unit of a university hospi...
متن کاملAnalysis of multiple linear regression algorithms used for respiratory mechanics monitoring during artificial ventilation
Many patients undergo long-term artificial ventilation and their respiratory system mechanics should be monitored to detect changes in the patient's state and to optimize ventilator settings. In this work the most popular algorithms for tracking variations of respiratory resistance (R(rs)) and elastance (E(rs)) over a ventilatory cycle were analysed in terms of systematic and random errors. Add...
متن کاملRespiratory mechanics studied by multiple linear regression in unsedated ventilated patients.
Respiratory mechanics during artificial ventilation are commonly studied with methods which require a specific respiratory pattern. An alternative is to analyse the relationship between tracheal pressure (P) and flow (V') by multiple linear regression (MLR) using a suitable model. The value of this approach was evaluated in 12 unsedated patients, mechanically-ventilated for acute respiratory fa...
متن کاملNurses' detection of ineffective inspiratory efforts during mechanical ventilation.
UNLABELLED BACKGROUND PATIENT: ventilator dyssynchrony is common and may influence patients' outcomes. Detection of such dyssynchronies relies on careful observation of patients and airway flow and pressure measurements. Given the shortage of specialists, critical care nurses could be trained to identify dyssynchronies. OBJECTIVE To evaluate the accuracy of specifically trained critical care ...
