/valˈsalvə/

Etymology: < the name of Antonio M. Valsalva (1666–1723), Italian anatomist.

Medicine.

Used attributively, in the possessive, and absol. to designate the action, described by Valsalva, in which an attempt is made to exhale air while the nostrils and mouth, or the glottis, are closed, so as to increase pressure in the middle ear and the chest.

1886 A. H. Buck Ref. Handbk. Med. Sci. II. 577/2 To insure a proper performance of this (Valsalva's) method of inflation, it is merely requisite that the patient shall make a strong expiratory effort while holding both his mouth and his nose firmly closed.

1893 H. Richards in C. H. Burnett Syst. Dis. Ear, Nose, & Throat I. i. 112 The patient is the operator of the Valsalva inflation.

1913 Jrnl. Physiol. 46 186 The radial artery was released and the first rise of the Valsalva experiment was resumed.

1913 Jrnl. Physiol. 46 186 In Fig. 5 is shown another tracing of occlusion of the aberrant radial artery during Valsalva.

1913 Jrnl. Physiol. 46 187 The first rise in the sphygmographic curve in Valsalva's experiment is due to increased blood-pressure with increase of the calibre of the artery.

1943 Bull. Hist. Med. 14 313 Only the historian can fully realize the relative unfruitfulness of the vast amount of experimentation and of study devoted to the Valsalva.

1972 Sci. Amer. Feb. 85/2 In attempting to stop the heart the yogis usually performed what is called the Valsalva maneuver.

1977 Lancet 28 May 1140/1 In shallow diving an over-forceful Valsalva manœuvre may give rise to neuro-sensory hearing loss, with or without vertigo.
