Pneumocephalus by Valsalva’s maneuver
Neurology, 2003Pneumocephalus (the accumulation of intracranial air) usually is associated with trauma, neoplasm, infection, or surgery. Spontaneous pneumocephalus is rare.1-7⇓⇓⇓⇓⇓⇓ We describe a patient with a large, asymptomatic pneumocephalus caused by the frequent performance of Valsalva’s maneuver.

Misconception of the Valsalva maneuver
International Urogynecology Journal, 2011Dear Editor, In urogynecology, we notice a lack of scientific data regarding breathing-dependent synergies between diaphragm and pelvic floor muscles, and associated changes in intraabdominal and intrathoracic pressure distribution. In particular, the Valsalva maneuver, which is often applied to support urine or stool evacuation and to evaluate stress ...

Valsalva maneuver in phlebologic practice
Phlebology: The Journal of Venous Disease, 2017Forced expiration against an airway obstruction was originally described as a method for inflating the Eustachian tubes and is accredited to Antonio Maria Valsalva (1666–1723). The Valsalva maneuver is commonly applied for different diagnostic purposes. Its use for phlebologic diagnosis is the object this review.

Valsalva maneuver in echocardiography
Journal of Echocardiography, 2016The Valsalva maneuver is an easily performed maneuver with an interesting hemodynamic effect which can be used to aid accurate echocardiographic diagnosis. However, correct adequate performance is often missed. Here, we aim to describe the performance of an adequate Valsalva maneuver and the correct interpretation of its effect.

The Valsalva Maneuver and Response Revisited
Mayo Clinic Proceedings, 1986The Valsalva maneuver is a time-honored technique that is commonly used at the bedside for the evaluation of heart murmurs. It is also a valuable adjunct in the evaluation of left ventricular function and autonomic dysfunction. In this article, we describe the normal and abnormal responses to the Valsalva maneuver and provide insight into the ...

The Valsalva Maneuver in Vasodepressor Syncope
Angiology, 1989In this work the authors propose the Valsalva maneuver as a diagnostic test in a group of patients shown, by anamnestic, physical, and instrumental crite ria, to be affected by vasodepressor syncope. They studied the response of heart rate and baseline arterial pressure to the maneuver performed in passive orthostasis in 7 healthy volunteers and 24 ...

The valsalva maneuver in the study of syncope
Electroencephalography and Clinical Neurophysiology, 1961Abstract The Valsalva maneuver can, in susceptible individuals, produce episodes with clinical and EEG features identical to those described by Gastaut in convulsive syncope induced by a reflex asystole. A severe hypotension of 6 sec or longer invariably precedes the onset of syncope. The addition of a Valsalva maneuver to the EEG examination may be

The Valsalva Maneuver and Alzheimers Disease: Is there a link?
Current Alzheimer Research, 2009Recent research findings provide evidence for Alzheimer's disease-related changes in brain diseases, such as normal pressure hydrocephalus and traumatic brain injury, and in glaucoma at the level of the retinal ganglion cells. This is a group of diseases that affect central nervous system tissue and are characterized by elevation of intracranial or ...
