Question
The nurse is caring for a 70-kg patient in septic shock with a pulmonary artery catheter. Which hemodynamic value indicates an appropriate response to therapy aimed at enhancing oxygen delivery to the organs and tissues?No sweat, you're still learning!Arterial lactate level of 1.0 mEq/LCardiac output of 2.5 L/minMixed venous (SvO2 ) of 40%Cardiac index of 1.5 L/min/m2
Solution
The appropriate hemodynamic value that indicates an appropriate response to therapy aimed at enhancing oxygen delivery to the organs and tissues in a patient in septic shock would be an Arterial lactate level of 1.0 mEq/L.
Here's why:
-
Arterial lactate level of 1.0 mEq/L: Lactate is a byproduct of anaerobic metabolism, which occurs when tissues are not getting enough oxygen. A normal lactate level is less than 2.0 mEq/L. Therefore, a level of 1.0 mEq/L indicates that the tissues are receiving adequate oxygen.
-
Cardiac output of 2.5 L/min: This is low. Normal cardiac output for a 70-kg adult is 4-8 L/min. A low cardiac output means the heart is not pumping enough blood to meet the body's needs, which can lead to inadequate oxygen delivery.
-
Mixed venous (SvO2 ) of 40%: This is also low. Normal SvO2 is 60-80%. A low SvO2 indicates that the tissues are extracting more oxygen than usual from the blood, which can be a sign of inadequate oxygen delivery.
-
Cardiac index of 1.5 L/min/m2: This is also low. Normal cardiac index is 2.5-4.0 L/min/m2. A low cardiac index means the heart is not pumping enough blood relative to the patient's body size, which can lead to inadequate oxygen delivery.
Therefore, the arterial lactate level of 1.0 mEq/L is the best indicator among these options that the therapy is effectively enhancing oxygen delivery to the patient's organs and tissues.
