PAC, a diagnostic toll or a therapeutic modality?
In the critically ill patient hemodynamic monitoring is aimed to optimize which of the following?
A 65yr old male 4 days post-op developed sudden onset of fever, chills and SOB. Vitals show HR 130, BP 85/55 mmHg, RR40/min, PaO2 40mmHg.
He was intubated and given 500cc NS, started on vasoactive therapy, and referred to MICU.
Your immediate action should be:
A. give volume
C. leave volume status as is
And / Or
A. give more vasopressor therapy
B. Taper vasopressor therapy
C. leave vasoactive therapy as is
A searchlight cannot be used effectively without a fairly thorough knowledge of the territory to be searched.
