The purpose of this study was to investigate the influence of the Valsalva maneuver (VM) on cardiac hemodynamics in patients with patent foramen ovale (PFO). Sixty-five patients who were highly suspected to have PFO were included. The changes in E, A, E/A ratio of mitral valve blood flow, E, A, E/A ratio of tricuspid valve blood flow, left ventricular end-diastolic volume, area and right atrial...

BACKGROUND Evaluate the feasibility of active delivery of the anterior arm during spontaneous delivery. This maneuver could decrease incidence of second-degree perineal tears because it reduces fetal biacromial diameter. METHODS An observational comparative prospective study was conducted at our teaching maternity from July 2012 to March 2013. The study included 199 nulliparous women ≥18 year...

UNLABELLED Benign Paroxysmal Positional Vertigo is one of the most common causes of dizziness. Its characteristic clinical profile is dizziness at head movements. The main diagnostic maneuver of posterior canal Benign Paroxysmal Positional Vertigo is the Dix-Hallpike test. If the maneuver is positive (vertigo and/or nystagmus), the physician can perform the Epley maneuver on the injured side. ...

[Purpose] The purpose of this study was to compare the effect of childbirth delivery method on vaginal pressure and abdominal thickness during the Valsalva maneuver (VAL). [Subjects] Thirty healthy female volunteers (26-39 years of age) were selected for this research. Their delivery histories were: nulliparous 10, vaginal delivery 10, and Cesarean delivery 10. None of the participants had a hi...

UNLABELLED The effects of Epley's maneuver in benign paroxysmal positional vertigo (BPPV) associated with Menière's disease are controversial. AIMS To evaluate the progression of positional vertigo and nystagmus after one or more of Epley's maneuvers in BPPV associated with Menière's disease, and the recurrence of BPPV. METHOD a retrospective study of 62 patients with BPPV associated with M...

Introduction The use of vagal nerve stimulation is identified as a proper treatment option in patients with stable supraventricular tachycardia (SVT). This study aimed to assess the success of Valsalva maneuver via a handmade device in reversion of SVT. Methods In this quasi experimental study, using a handmade device, vagus nerve stimulation was performed for SVT patients presenting to emerg...

UNLABELLED The effectiveness of postmaneuver postural restrictions is controversial in patients with benign paroxysmal positional vertigo. AIM To verify the role of postural restrictions in patients with benign paroxysmal positional vertigo of posterior canal, submitted to a single Epley maneuver. STUDY DESIGN clinical prospective. MATERIAL AND METHOD Fifty eight patients with benign paro...

OBJECTIVE This study investigated the acute hemodynamic responses to multiple sets of passive stretching exercises performed with and without the Valsalva maneuver. METHODS Fifteen healthy men aged 21 to 29 years with poor flexibility performed stretching protocols comprising 10 sets of maximal passive unilateral hip flexion, sustained for 30 seconds with equal intervals between sets. Protoco...

This study was performed to compare continuous Finapres (FIN) and intrabrachial (IAP) blood pressure in healthy elderly volunteers. Fifteen elderly subjects (age 71 to 83) without cardiovascular disease and an intraarterial mean (range) systolic and diastolic blood pressure of 162 (122 to 195) and 73 (62 to 88) mm Hg, respectively, participated in the study. A 10-min head-up tilt, 10 min active...
