摘要:

A retrospective study of 20 surgical intensive care unit patients is reported. They were ventilated with continuous positive pressure ventilation (CPPV) and then switched to combined high frequency ventilation (CHFV). To find why there were variable responses to CHFV, the data of 20 patients were retrospectively evaluated with respect to respiratory index (RI), compliance (C) and extravascular lung water (EVIAV). The results suggest that the indication line for CHFV was a C value>45 ml/cmH2O and an EVLW value>15 ml/kg BW.

摘要:

Non‐biological descriptors such as jet feeding pressure and oscillator stroke volume are often used to describe HFV. This results in confusion and hinders acceptance of HFV. The goal of this paper is to show how physiological parameters which are valid during HFV can be monitored. Airway pressure measured in narrow tubes with high linear flow rates is underestimated. A relevant airway pressure must be measured well below the tracheal tube. Pressure measured higher up should be validated against peripheral pressure measurements. Minute ventilation and expired CO2concentration can be determined with a ServoVentilator and a CO2analyzer arranged at its exit port. Minute ventilation and CO2elimination can thereby be continuously monitored during high frequency jet ventilation or so‐called “combined high frequency jet ventilation” to prevent undetected disturbance of ventilation and perfusion. Physiological dead space can be studied for optimization of ventilatory pattern. The principle of gas analysis at the exit port of the ventilator may be used for FRC determinations with sulfur‐hex
