The Valsalva maneuver may help check for a dural tear following certain spinal operations, such as a microdiscectomy. An increase in intra-spinal pressure will cause cerebral spinal fluid (CSF) to leak out of the dura, causing a headache. [citation needed] The Valsalva maneuver has been associated with transient global amnesia. [17] [18] [19 ...
The Trendelenburg position along with the Valsalva maneuver, termed as modified-Valsalva maneuver, can also be used for the cardioversion of supraventricular tachycardia. [ 5 ] The Trendelenburg position is helpful in surgical reduction of an abdominal hernia.
CSF pressure has been shown to be influenced by abrupt changes in intrathoracic pressure during coughing (which is induced by contraction of the diaphragm and abdominal wall muscles, the latter of which also increases intra-abdominal pressure), the valsalva maneuver, and communication with the vasculature (venous and arterial systems).
Diver clearing ears Section of the human ear, the Eustachian tube is shown in colour. Ear clearing, clearing the ears or equalization is any of various maneuvers to equalize the pressure in the middle ear with the outside pressure, by letting air enter along the Eustachian tubes, as this does not always happen automatically when the pressure in the middle ear is lower than the outside pressure.
A peripherally inserted central catheter (PICC or PICC line), also called a percutaneous indwelling central catheter or longline, [1] is a form of intravenous access that can be used for a prolonged period of time (e.g., for long chemotherapy regimens, extended antibiotic therapy, or total parenteral nutrition) or for administration of substances that should not be done peripherally (e.g ...
There is believed to be a correlation between volume of amniotic fluid retained and neonatal outcomes before 26 weeks' gestation. [10] Amniotic fluid levels are an important consideration when debating expectant management vs clinical intervention, as low levels, or oligohydramnios, can result in lung and limb abnormalities.

Antonio Maria Valsalva (17 January 1666 – 2 February 1723), was an Italian anatomist born in Imola. His research focused on the anatomy of the ears . He coined the term Eustachian tube and he described the aortic sinuses of Valsalva in his writings, published posthumously in 1740.
Tympanic membrane retraction describes a condition in which a part of the eardrum lies deeper within the ear than its normal position.. The eardrum comprises two parts: the pars tensa, which is the main part of the eardrum, and the pars flaccida, which is a smaller part of the eardrum located above the pars tensa.
