IPPV
In intensive care and emergency medicine, IPPV is an abbreviation for intermittent positive pressure ventilation ( German: Ventilation with intermittent positive pressure) and describes a specific, volume-controlled form of ventilation with a ventilator . This ventilation method was further developed in the 1950s by the Danish doctor Björn Ibsen for the treatment of poliomyelitis.
Synonymous with the abbreviation IPPV, the term Volume Controlled Ventilation is used more often today and is abbreviated to VCV.
It is a so-called volume - controlled ventilation , i. H. the ventilator tries to keep the volume constant and varies the ventilation pressure to do this. With this form of ventilation, the air pressure in the airways drops to 0 mmHg at the end of exhalation ( expiration ) , but does not reach negative values. Pressure-controlled ventilation is mostly used today. It specifies two different pressure levels, one for inhalation and one for exhalation. This ventilation is called bilevel or BIPAP , in which there is still positive pressure ( PEEP ) in the airways at the end of expiration .
S-IPPV ventilation (Synchronized Intermittent Positive Pressure Ventilation) is synchronized IPPV ventilation. Here the patient's breathing efforts (“triggers”) are recognized and supported in a synchronized manner.
