Answers
The volume of blood the heart pumps per minute
cardiac output (CO)
adjusted for body surface area
Cardiac index (CI)
reflects right ventricular preload
Central venous pressure (CVP)
reflects left ventricular end-diastolic pressure
PAWP (pulmonary artery wedge pressure)
The resistance the left ventricle must overcome to pump blood
Systemic vascular resistance (SVR)
What diagnostic study is used to diagnose shock?
No single study determines shock
Which blood study findings are commonly associated with shock?
Elevated lactate levels and a base deficit.
What imaging and monitoring studies are used when assessing a patient for shock?
12-lead electrocardiogram (ECG), continuous electrocardiogram (ECG) monitoring, chest X-ray,
and continuous pulse oximetry
What is the primary factor that distinguishes one type of shock from another?
The mechanism responsible for decreased tissue perfusion and cellular hypoxia
Which shock is classified by either systolic dysfunction (inability to pump blood forward) or
diastolic dysfunction (inability to fill).
Cardiogenic shock
