On-line monitoring of intrinsic PEEP in ventilator-dependent patients.
Measurement of the intrinsic positive end-expiratory pressure (PEEP(i)) is important in planning the management of ventilated patients. Here, a new recursive least squares method for on-line monitoring of PEEP(i) is proposed for mechanically ventilated patients. The procedure is based on the first-order model of respiratory mechanics applied to experimental measurements obtained from eight vent...
متن کاملBurden on caregivers of ventilator-dependent patients
Caring for prolonged mechanical ventilation (PMV) patients imposes heavy psychological, physical, social, and financial burdens on caregivers. Currently, studies regarding the burden on caregivers of PMV patients are scant; therefore, the present study investigated the burden on caregivers of PMV patients.This cross-sectional study was approved by the Institutional Review Board of Zuoying Armed...
متن کاملComparing the Effect of Using Normal Saline and Distilled Water for Tracheal Suctioning on the Incidence of Ventilator-associated Pneumonia and Hemodynamic Indexes in Ventilator-dependent Patients
Background and Aims: VAP prevention is a top priority in the intensive care units. The study was conducted to compare the effect of using normal saline and distilled water for tracheal suctioning on the incidence of ventilator-associated pneumonia and hemodynamic indexes in ventilator-dependent patients. Methods: The present study is a randomized clinical trial that was conducted from 2017 to 2...
متن کاملEffects of intrinsic PEEP on pulmonary gas exchange in mechanically-ventilated patients.
The aim of the study was to assess the impact of the intrinsic positive end-expiratory pressure (PEEPi) on pulmonary gas exchange in mechanically-ventilated patients, by comparing the effects of similar levels (0.8-0.9 kPa) of positive end-expiratory pressure (PEEP) and PEEPi. Ten patients with acute respiratory failure, without chronic airway disease, were studied with three ventilatory modes:...
متن کامل"Intrinsic" PEEP (PEEPi): role of expiratory muscles.
In normal subjects breathing at rest, lung volume at end-expiration corresponds with the elastic equilibrium volume, or relaxation volume (Vr), of the respiratory system. If expiratory duration is not long enough, then inspiration may begin before the system has returned to Vr, such that end-expiratory lung volume is higher than Vr. This condition is named dynamic pulmonary hyperinflation and "...
