Critically Ill Patients Admitted in ICU Clinical Trial
Hypoxemia is usually observed during ICU stay. Nevertheless, the prevalence of hypoxemia
among patients admitted in ICU is not well known, in partly due to a lack of a consensual
definition. Some of these patients meet the criteria of Acute Respiratory Distress Syndrome
whom the definition has been recently modified in 2011. Many uncertainties are remaining in
considering the patients with ARDS: prevalence of the category of "mild ARDS", the proportion
of patients with invasive mechanical ventilation, the therapeutic modalities and the
prognosis, in particular, the move towards a more severe ARDS category. Finally, many
patients with hypoxemia do not meet ARDS definition. The prevalence of this population in ICU
is unknown, likewise its prognosis. In this way, it would be interesting to compare, for each
levels of hypoxemia (mild, moderate and severe) the prognosis of the patients with and
without ARDS.
The main objective of the SPECTRUM study is to assess the prevalence of hypoxemia in
French-speaking Intensive Care Unit in 2016 in using a single-day point-prevalence study
design. Two periods of inclusion have been, actually, planned: from the 29th Mars to the 31st
Mars and from the 5th to the 7th April. In each participating center, the day of the study
will be chosen among these periods.
