Proportional Pressure Support Ventilation - Mechenical-Ventilation-Scene-Content-Image-16-6-D-11155-2019 — Proportional Pressure Support Ventilation

Proportional Pressure Support (PPS) has shown to reduce asynchronies and duration of ventilation

PPS (Proportional Pressure Support) is a proportional mode that was associated with a reduction in incidence with AI >10%¹ and duration of ventilation² when compared with PSV (Pressure Support Ventilation).
Patient-ventilator asynchrony is considered high when the Asynchrony Index (AI) is >10%³, and it is associated with longer ventilation times⁴ and higher mortality rates⁵.
While the support during PSV always remains constant, in PPS, support is provided proportionally. This proportional delivery results in support being provided only when it is needed.

Patient comfort – a clinical priority

Up to 60 – 80% of mechanically ventilated patients in the ICU are affected by delirium⁶

We focus on

Allowing variability of spontaneous breathing, avoiding asynchronies
Improving sleep quality
Matching individual ventilation requirements

Improve sleep quality

Proportional ventilation resulted in fewer patient-ventilator asynchronies and better quality of sleep compared to pressure support ventilation⁷.

Lower patient-ventilator asynchronies per hour at 24±15 vs. 53±59⁸.
Fewer awakenings per hour at 3.5 (range 0-24) vs. 5.5 (range 1-24)⁹.

PPS, efficient weaning, and more

From a study of 87 ICU patients¹⁰, compared to patients on ventilators using the common ASB (Assisted Spontaneous Breath) ventilation mode, patients on ventilators using PPS (Proportional Pressure Support) had

Reduced incidence of high man-machine confrontation from 27% to 9%¹¹,
Reduced failure rate of first spontaneous breathing trial (SBT) from 23% to 7%¹², and
Shortened ventilator weaning time from 51±38 to 13±14 hours¹³.
