PAC insertion
❖ After inserting the PAC as far as the 20cm mark,the balloon is inflated with air.
❖ Inflation should be slow and controlled (1 mL/s) and should not surpass the recommended volume (1.5 mL).
❖ Differentiation of pulmonary edema Cardiogenic Noncardiogenic
❖ Evaluation of pulmonary hypertension ❖ Diagnosis of left-to-right intracardiac shunt ❖ Diagnosis of pericardial tamponade
Vasopressors; Inotropes ; Vasodilators ❖ Guide to nonpharmacologic therapy
Fluid management ;Burns ; Renal failure ; Sepsis ; Heart failure ;Decompensated cirrhosis ❖ Ventilator management Assessment of best PEEP for DO2

Structure of PAC
❖ Always inflate the balloon before advancing the PAC and always deflate the balloon before withdrawing the PAC.
❖ CRX:check the position of the PAC
❖ PA diastolic pressure ~ PAWP

❖ Left subclavian Does not require the PAC to pass and course at an acute angle to enter the SVC
❖ Femoral veins Distant sites Passing a PAC into the heart can be difficult Fluoroscopic assistance may be necessary Compressible and preferable if the risk of hemorrhage is high
