The criteria suggested from these 2 conferences are that 2 or more of the following cardiovascular reflex tests should be abnormal: (1) deep breathing test, (2) Valsalva maneuver, (3) 30: 15 index, and (4) orthostatic hypotension.
Entretanto outra importante variavel muito vezes negligenciado e a manobra de Valsalva (MV), que pode ocasionar alteracoes na resposta hemodinamica.
In our study, the Valsalva maneuver was performed intra-operatively by the attending anesthetist.
Cheung et al.[16] showed that pessary expulsion within 1 year was significantly associated with increased hiatal areas on rest, contraction and valsalva, and a higher rate of avulsion.

The clear winner in terms of efficacy was the modified Valsalva maneuver, in which patients with supraventricular tachycardia (SVT) performed a standardized strain while in a semirecumbent position, then immediately laid flat and had their legs raised to 45 degrees for 15 seconds before returning to the semirecumbent position.
It has been postulated that patients with excessive hyperemesis may experience this phenomenon in the pre natal period, however most cases occur in the second stage of labour, with excessive straining and valsalva maneuvers specially in primigravidas with a prolonged labour, which clinically do not become symptomatic till the post partum phase.
PV obliquely perforates the deep muscular fascia and associates the with the superficial vein (a), diameter of PV measured at the suprafascial-subfascial connection level (b), augmentation of blood flow by compression of the limb below PV and Valsalva's maneuver are used to assess valvular integrity with color flow imaging (c), and spectral Doppler imaging (d)
In the evaluation of TPPs obtained after the Valsalva maneuver, there was no statistically significant change for the contralateral side of the deviation (p=0.12), whereas a significant change was observed in the side of deviation (p<0.05) (Table 2).

Additional tools for evaluating ETD and the effect of BET include Valsalva and Toynbee maneuvers, tubomanometry, Eustachian Tube Score (ETS), ETS-7 (extension of ETS), and Eustachian Tube Dysfunction Questionnaire (ETDQ-7) [3,5-7].
