Effects of frequency, tidal volume, and lung volume on CO2 elimination in dogs by high frequency (2-30 Hz), low tidal volume ventilation.

High-frequency percussive ventilation: pneumotachograph validation and tidal volume analysis.

INTRODUCTION High-frequency percussive ventilation (HFPV) is an increasingly used mode of mechanical ventilation, for which there is no proven real-time means of measuring delivered tidal volume (V(T)). OBJECTIVE To validate a pneumotachograph for HFPV and then exploit flow-sensor data to describe the behavior of both low-frequency and high-frequency breaths. METHODS Sensor performance was ...

Intraoperative low-tidal-volume ventilation.

High-frequency percussive ventilation and low tidal volume ventilation in burns: a randomized controlled trial.

OBJECTIVES In select burn intensive care units, high-frequency percussive ventilation is preferentially used to provide mechanical ventilation in support of patients with acute lung injury, acute respiratory distress syndrome, and inhalation injury. However, we found an absence of prospective studies comparing high-frequency percussive ventilation with contemporary low-tidal volume ventilation ...

One-Lung Ventilation with Additional Ipsilateral Ventilation of Low Tidal Volume and High Frequency in Lung Lobectomy

BACKGROUND To investigate the protective effects of additional ipsilateral ventilation of low tidal volume and high frequency on lung functions in the patients receiving lobectomy. MATERIAL AND METHODS Sixty patients receiving lung lobectomy were randomized into the conventional one-lung ventilation (CV) group (n=30) and the ipsilateral low tidal volume high frequency ventilation (LV) group (n=...

Low Tidal Volume Ventilation: Trust but Verify.

Despite affecting an estimated 4 –7% of patients in the ICU and having a high mortality rate, there are currently a limited number of therapeutic options to treat patients with ARDS.1,2 ARMA, the landmark ARDSnet trial in 2000, established the concept of lungprotective ventilation, where subjects with ARDS receiving mechanical ventilation were randomly assigned to a set tidal volume (VT) of eit...
