Which of the following is a dynamic parameter that suggests fluid responsiveness?
Understand the Problem
The question asks to identify which of the given options is a dynamic parameter used to assess fluid responsiveness in a patient. Fluid responsiveness refers to the ability of a patient's cardiac output to increase in response to fluid administration. Dynamic parameters are more reliable indicators of fluid responsiveness compared to static parameters like CVP.
Answer
Pulse Pressure Variation (PPV)
Pulse Pressure Variation (PPV) is a dynamic parameter that suggests fluid responsiveness.
Answer for screen readers
Pulse Pressure Variation (PPV) is a dynamic parameter that suggests fluid responsiveness.
More Information
Pulse Pressure Variation (PPV) is a dynamic parameter used to assess fluid responsiveness, which refers to how well a patient's cardiac output increases in response to fluid administration. Other dynamic parameters include Stroke Volume Variation (SVV).
Tips
It is important to note that these parameters are most reliable in patients who are mechanically ventilated and in sinus rhythm.
