Proning patients with Acute Respiratory Distress Syndrome may increase oxygenation and reduce mortality, but the practice is difficult to perform manually.
Large prospective, randomized trial shows prone therapy improved survival in patients with ARDS or hypoxemia
DATA FROM CLINICAL STUDY: “Prone Positioning in Severe Acute Respiratory Distress Syndrome”. C Guerin et al. N Engl J Med 2013; 368: 2159-2169
Mortality of prone patients @ day 28 was significantly lower (16%) than supine group (P<0.001)
Kaplan-Meier Plot of the Probability of Survival from Randomization to Day 90.
PaO2/FiO2 ratio improved during prone therapy sessions.
Mean values of PAO2/FiO2 (mm Hg) in the Prone Position group during the first five sessions (S1: n=170; S2: n=130; S3: n=99; S4: n=71; S5: n=51) (M1 = supine just before proning; M2 = one hour after proning; M3 = end of proning just before going back into the supine position; M4 = 4 hours after supine positioning)
