![]() Most importantly, one should support the pelvis by at least two to three pillows to create no pressure on the stomach. The patient should place one pillow below the upper chest and below the shin while lying with their face down. One must start by lying down on their stomach for half an hour to two hours, depending on their comfort. The alternation between these positions needs to be done regularly to maintain ease and comfort. Proning is a combination of some positions that allow the lungs to take in oxygen more efficiently. If diligently followed proning maneuvers can ease breathing to a great extent. The effects of this intervention on outcomes are still uncertain.Īcute respiratory distress syndrome Gravity Lung protective ventilation Prone position Ventilation/perfusion.To correctly attain the prone position, doctors have laid down some guidelines. Recently, the use of prone position has been extended to non-intubated spontaneously breathing patients affected with COVID-19 ARDS. The most frequent adverse events are pressure sores and facial edema. The maneuver to change from supine to prone and vice versa requires a skilled team of 4-5 caregivers. The only absolute contraindication for implementing prone position is an unstable spinal fracture. The main reason explaining a decreased mortality is less overdistension in non-dependent lung regions and less cyclical opening and closing in dependent lung regions. Improvement in oxygenation and reduction in mortality are the main reasons to implement prone position in patients with ARDS. The change to prone position is generally accompanied by a marked improvement in arterial blood gases, which is mainly due to a better overall ventilation/perfusion matching. ARDS patients, the change from supine to prone position generates a more even distribution of the gas-tissue ratios along the dependent-nondependent axis and a more homogeneous distribution of lung stress and strain. 14 Servei Medicina Intensiva, Hospital Universitari Sant Pau, Barcelona, Spain.13 University Hospital Ambroise Paré, APHP, Boulogne-Billancourt, and Université de Versailles Saint Quentin en Yvelines UMR 1018, Boulogne-Billancourt, France.12 Dipartimento Di Anestesia, Rianimazione ed Emergenza Urgenza, Fondazione IRCCS Cà Granda-Ospedale Maggiore Policlinico, Milan, Italy.11 Faculté de Médecine, Groupe de Recherche en Réanimation Et Anesthésie de Marseille Pluridisciplinaire (GRAM +), Aix-Marseille Université, Centre d'Etudes et de Recherches sur les Services de Santé et qualité de vie EA 3279, 13005, Marseille, France.10 Médecine Intensive Réanimation, Assistance Publique, Hôpitaux de Marseille, Hôpital Nord, 13015, Marseille, France.9 Interdepartmental Division of Critical Care Medicine, Mount Sinai Hospital, Sinai Health System, University of Toronto, Toronto, Canada.8 Departments of Critical Care Medicine, Regions Hospital and University of Minnesota, Minneapolis-St.7 Critical Care and Anesthesia Department (DAR B), Hôpital Saint-Éloi, CHU de Montpellier, PhyMedExp, Université de Montpellier, Montpellier, France.6 Department of Anesthesiology, Emergency and Intensive Care Medicine, University of Göttingen, Göttingen, Germany.5 Center for Acute Respiratory Failure and Division of Pulmonary, Allergy, and Critical Care Medicine, Columbia University College of Physicians and Surgeons, New York, NY, USA.4 Department of Medicine, University of Colorado, Aurora, USA.3 Institut Mondor de Recherche Medicale INSERM 955, ERL CNRS 7000, Créteil, France.1 Médecine Intensive-Réanimation, Hôpital Edoudard Herriot, Lyon, France.
