Ventilation method and ventilation device

摘要

The present invention relates to a method for the ventilation of a living being (3), the respiration airflow (v) flowing into the living being (3) and out of the living being (3) being detected, it being ascertained from the detected respiration airflow (v) whether an inhalation phase or an exhalation phase is present, and the air pressure (p) in a respiratory organ of the living being (3) being regulated, characterized in that, upon recognition of an inhalation phase, the air pressure (p) in the respiratory organ is raised at the beginning of the inhalation phase and lowered again with progressing respiration cycle.

1. Method for the ventilation of a living being, performed by a ventilation device, comprising the steps of:
detecting a respiration airflow ({dot over (v)}) flowing into the living being and out of the living being, ascertaining from the detected respiration airflow ({dot over (v)}) whether an inhalation phase or an exhalation phase is present, regulating an air pressure (p) in a respiratory organ of the living being, wherein, upon recognition of an inhalation phase in the step of ascertaining, initially raising the air pressure (p) in the respiratory organ at the beginning of the inhalation phase from an initial value of the air pressure (p), which was set at the beginning of the inhalation phase as the starting value (Po), to a predetermined amount, maintaining the air pressure (p) at said predetermined amount during the inhalation phase and into the exhalation phase, and then lowering the air pressure (p) at the end of the exhalation phase to the starting value (Po) and wherein upon recognition of an exhalation phase in the step of ascertaining, raising the air pressure (p) in the respiratory organ at the beginning of the exhalation phase.
