Organ Dysfunction Score for Obstetric Patients

The goal of this observational study is to develop and evaluate an organ dysfunction score adapted to pregnancy and early puerperium (SOFA-OBS) that also incorporates a non-invasive tool to evaluate respiratory function (pulse oximeter). The main question it aims to answer is: Does an organ dysfunction score adapted to pregnant and postpartum patients have a higher capacity to predict mortality than a non-adjusted organ dysfunction score? Participants: Patients requiring ICU (Intensive Care Units) admission, who are either pregnant or postpartum (up to 3 days after giving birth). The investigators aimed to include 130 participants. The investigators will only collect participants' data and laboratory results that ICU doctor usually need for clinical practice. No additional interventions are required. Moreover, the investigators will evaluate if measuring participants' oxygenation throu
