Associations of arterial oxygen partial pressure with all‑cause mortality in critically ill ischemic stroke patients: a retrospective cohort study from MIMIC IV 2.2.

ABSTRACT:

Background

As a supportive treatment, the effectiveness of oxygen therapy in ischemic stroke (IS) patients remains unclear. This study aimed to evaluate the relationships between arterial partial pressure of oxygen (PaO₂) and both consciousness at discharge and all-cause mortality risk in ICU IS patients.

Methods

Blood gas measurements for all patients diagnosed with IS were extracted from the MIMIC-IV database. Patients were classified into four groups based on their average PaO₂ during the first ICU day: hypoxemia (PaO₂ < 80 mmHg), normoxemia (PaO₂ 80-120 mmHg), mild hyperoxemia (PaO₂ 121-199 mmHg), and moderate/severe hyperoxemia (PaO₂ ≥ 200 mmHg). The primary endpoint was 90-day all-cause mortality. Second
