2. Perform analysis
Compliance changes during PEEP trials are conveniently displayed as a
series of images and a diagram. At lower PEEP levels, those compliance
changes may indicate collapse, at higher PEEP levels overdistension,
respectively. Based on this information, an individualized PEEP level can be
chosen, where the loss of compliance and the underlying adverse effects
are minimized.
4.3. InFLUEnCE OF POSITIOnInG On ThE dISTrIBUTIOn
OF vEnTILaTIOn
The positioning of a body has an influence on the ventilation of the
lungs. The change in ventilation can be visualized with PulmoVista
®
500. Whether and to what extent patient positioning promises success
depends on the individual status of the patient, but the effect can be seen
immediately after the situation at EIT has changed. Here is an example of a
healthy lung during natural spontaneous breathing. The ventilation
distribution of a mechanically ventilated patient with impaired respiratory
function will be exactly reversed. The arrows represent the gravity vectors, the
numbers represent the regional distribution of ventilation.
