We designed a computerized system allowing a closed-loop control of the PSV level. The system reaches the lowest level of PSV to keep respiratory rate (RR), tidal volume (Vt) and end-tidal pressure of CO2 within a certain range (i.e. 12300 ml or 250 if weight < 55 Kg, PetCO2 < 55 mmHg or 65 if chronic CO2 retention), defining acceptable ventilation. Ten patients were randomly ventilated during 2 periods of 24 hours with the computer-controlled (automatic) PSV or with physician-controlled (standard) PSV, where PSV was modified by the clinician in charge. An estimation of the occlusion pressure (P0.1) was continuously recorded. The average time spent with the defined acceptable ventilation was found to be 66±24 % of the total duration of ventilation with standard PSV and 93±8 % with automatic PSV (p<0.05), while the level of support was similar in the two periods (17±4 cmH2O and 19±6 cmH2O). The time spent with an estimated P0.1 above 4 cmH2O amounted to 34±35 % of the time with standard PSV and decreased to 11±17 % with automatic PSV (p<0.01). The automatic PSV system allowed the patient to spend more time within physician predefined limits and presumably could reduce periods of excessive workload. |
