ARISTIZABAL, R.E. et al. RELATION OF THE CONTRIBUTION OF OXYGEN AND THE SURVIVAL OF THE PATIENT WITH SHOCK IN UCI. Investig. andina [online]. 2012, vol.14, n.25, pp.588-600. ISSN 0124-8146.

Introduction: to establish the repercussion between survival of the critically ill patient-diagnosed with shock (all kinds of etiology)-and the diagnosis of acid/ base balance of the blood gas analysis. Methods: prospective cohort study. Setting: one general Intensive Care Unit. Patients: Ppatients diagnosed with shock to whom blood gas analysis was made. Variables of interest: outcome defined as survival of the patients in function of time. Moreover, some variables were monitored such as acid/base balance, respiratory function, ventilatory function and blood electrolytes. They were all monitored in function of time. Results: the Cox regression model showed that male patients diagnosed with shock had 2.78 times greater risk of dying compared to women. FiO₂ and THBc variables work as mortality predictors while PAO₂, PCO₂, and PO₂ variables are protective factors for mortality. Conclusion: early diagnostic in acid/base balance of patients with shock-arriving at the intensive care unit-and immediate therapeutic intervention of those variables part of tissue oxygen delivery (such as PAO₂, FiO₂, THBc, PCO₂, and PO₂) will favorably change the prognostic and survival of the patients.
