Queckenstedt's maneuver, or Queckenstedt's test, is a test for detecting blockage of the cerebrospinal fluid (CSF) in the spinal canal.[1] The maneuver is compressing both jugular veins while measuring CSF pressure. The same may happen from compressing the abdominal veins.[2] In the normal patient, Queckenstedt's maneuver leads to a transient rise in pressure of the CSF of about 4 cm H2O or more (mercury is 13.6 times more dense than water).[3]
