      We observed forearm vasodilatation following the Valsalva manoeuvre in 11 out of 19 normal subjects; the remainder showed a persistent forearm vasoconstriction (Bennett et al. 1979b).

      When that time comes, a person may perform the Valsalva manoeuvre, increasing the pressure inside the abdomen by exhaling against a closed airway as if popping one’s ears on a flight.
    • 2019, David Chambers, Christopher Huang, Gareth Matthews, Basic Physiology for Anaesthetists, Cambridge University Press, 2nd Edition, page 175,
      The Valsalva manoeuvre is performed by forced expiration against a closed glottis. It is attributed to Antonio Valsalva (1666–1723), who described it as a test of Eustachian tube patency and as a method of expelling pus from the middle ear.
