Assessment of Blood Viscosity in ARDS (Acute Respiratory Distress Syndrome)

Sponsor: Hospices Civils de Lyon

Summary

Acute respiratory distress syndrome (ARDS) is characterized by damage to the alveolar-capillary membrane, resulting in hypoxemia, decreased pulmonary compliance, and hemodynamic changes. Critical conditions (hypoxia; septic shock associated with ARDS) can alter blood viscosity. These changes in viscosity can affect blood flow and hemodynamics. There is only one clinical study that has measured one of the determinants of blood viscosity in ARDS (deformability), even though other parameters are involved in viscosity (elongation, deformability, hematocrit, etc.), and it is possible to measure blood viscosity comprehensively. To date, therefore, no study has evaluated the various parameters of blood viscosity in ARDS. The aim of this study is to investigate hyperviscosity in patients with ARDS and to assess whether this hyperviscosity correlates with respiratory or hemodynamic changes. The investigators will therefore compare blood viscosity and its determinants in patients admitted to the intensive care unit for ARDS and in patients admitted for other reasons (excluding ARDS or sepsis/septic shock). The investigators will also conduct a longitudinal assessment of changes in hemodynamic, respiratory, and viscosity parameters during ARDS
