Abstract
Point-of-care ultrasound can be utilized in an algorithmic approach to the patient with undifferentiated shock. Within minutes, a focused ultrasonographic exam can aid in the clinical classification of the patient, allowing appropriate further testing and treatment to be initiated. In this chapter, we illustrate a protocol for the ultrasound evaluation of shock and also discuss the evidence for the use of ultrasonography in the assessment of intravascular volume status.
