ICU LOS for the 4920 patients is shown in Figure 2. The ILOS>30 group (n = 205) had a mean LOS of 45.5 ± 23.8 days (median 39, range 30 to 279 days) with a mean mechanical ventilation duration of 39.9 ± 21.1 days (median 38, range 7 to 192 days).
The average ICU length of stay is 7 days (2 30 days) with a mean mechanical ventilation duration of 48 h (1 10 days) and an inotropic support in 100% of patients.
Doig [14] showed that EPN resulted in significantly fewer days of invasive ventilation; however, the mean reduction of ventilation duration was only 0.47 days and could not be translated into a significantly shorter ICU or hospital length of stay.

Using ESPr predictions, the role of different building design and operational parameters are examined by means of parametric analysis including building mass, ventilation duration, internal gain and ventilation rates.
Furthermore, the study by Heidegger showed no differences in mechanical ventilation duration comparing LPN to EN (mean 153 versus 166 h; p = 0.2912 [15]).
