Sentence examples for ventilator drive from inspiring English sources

36 Moreover, dysfunction of central chemoreceptors and peripheral chemoreceptors leads to a decrease in hypoxemia and hypercapnic ventilator drive.

Though obesity is the main risk to develop OSA, craniofacial morphology and ventilator drive abnormalities are also important in OSA pathogenesis.

According to several authors a reduction in the ventilator drive, caused by hypoxia and hypercapnia, conduces to a decrease in pO2 and an increase in pCO2 [ 18– 22].

Respiratory-gated MR-ARFI prepared MRgHIFU ablation was performed in the kidney and liver of two sheep in vivo, under general anaesthesia and ventilator-driven forced breathing.

The present study demonstrated that "optimized ventilation", driven by the analysis of the waveforms generated by ventilators, may have a positive effect on physiological and patient-centered outcomes during acute exacerbation of COPD.

The aim of the present randomized, multi-centric, controlled study was to compare optimized ventilation, driven by the analysis of flow and pressure waveforms, to standard ventilation (same physician, same initial ventilator setting, same time spent at the bedside while the ventilator screen was obscured with numerical data always available).

◆ We compared, in patients under NIV for acute exacerbation of COPD, the efficacy of ventilator settings driven by the analysis of flow and pressure waveforms on the screen vs. a standard ventilation, where only numerical data were obtained from the ventilator.

The purpose of this randomized controlled study was to compare, in patients under NIV for acute exacerbation of COPD, the efficacy of ventilator settings driven by the analysis of flow and pressure waveforms on the screen (optimized ventilation) vs. a standard ventilation, where only numerical data were obtained from the ventilator.

The study ventilator was driven by an external control unit, which – in accordance with the study protocol – automatically changes the PEEP level in synchrony with the patient's breathing pattern (i.e. upward steps in PEEP during inspiration and downward steps during expiration).

Therefore, improved synchrony between the ventilator and respiratory drive may improve ventilation partly by limiting wasted ventilation at the level of the upper airway.
