The Valsalva's maneuver
was used to evaluate the valvular competence of DVS.
However, tennis requires upper body strength that in turn elicits Valsalva's maneuver
, which is more often associated with lifting heavy weights.
It usually occurs secondary to Valsalva's maneuver
, a forcible exhalation effort against a closed glottis, causing a sudden rise in intrathoracic pressure.
In upper segments, a higher frequency of reflux was found with semi-Fowler plus Valsalva's maneuver
; in intermediate segments there were similar reflux prevalences using both positions; and, in lower segments, there was more reflux using standing position plus Valsalva's maneuver
They can enlarge with crying, with Valsalva's maneuver
, or with compression of the jugular veins (Furstenberg's sign).
Still's murmur decreases in intensity with standing and during Valsalva's maneuver
, while HOCM does the opposite.
Luber and his associates found that when patients returned 1 month later, only 25% were doing Kegel exercises correctly Half weren't even attempting to do Kegel exercises, and 25% were doing a Valsalva's maneuver
Agreement existed on the following points: avoiding sustained pushing with a closed glottis (Valsalva's maneuver
); avoiding episiotomy; delivering between contractions; maintaining light pressure to prevent rapid expulsion of the infant; and delivering the anterior shoulder first.
(10) He postulated that an increase in alveolar pressure secondary to an increase in intrathoracic pressure against a total or partial obstruction (as occurs during Valsalva's maneuver
and explosive cough) leads to marginal alveolar rupture.
The patient is asked to sit on the commode at rest, squeeze her pelvic floor, perform Valsalva's maneuver
, and then defecate, with images taken throughout.
The abnormal blood pressure response to Valsalva's maneuver
seen in heart failure--a blunted pulse amplitude ratio--correlates with natriuretic peptide level, exercise capacity, clinical symptoms, and physical signs; in short, with every important prognostic indicator.
