Partial arterial carbon dioxide and oxygen pressure in patients with cardiogenic shock.

ABSTRACT: In patients with acute cardiovascular diseases, hypocapnia, hypoxia and hyperoxia are known to be associated with increased mortality. This monocentric prospective registry study included 238 consecutive patients with cardiogenic shock (CS). The study aimed to assess the prognostic impact of partial arterial carbon dioxide (PaCO₂) and oxygen pressure (PaO₂) on 30-day all-cause mortality. Statistical analyses included t-tests, Spearman´s correlation, Kaplan-Meier and Cox regression analyses. No difference was found between quartiles of PaCO₂ (log-rank p = 0.416) and PaO₂ (log-rank p = 0.946) in the entire cohort. In the subgroup of patients with ventilation on admission, patients with PaCO₂ ≤ 33 mmHg showed the highest 30-day all-cause
