the Valsalva maneuver could predict mortality in elderly patients with congestive heart failure. This could prove to be a new noninvasive way to help determine how long elderly patients with congestive heart failure are expected to live.
The Valsalva maneuver is used with patients who have suspected heart abnormalities, often in conjunction with echocardiography.
The Valsalva maneuver can be safe when done correctly, but it can also be risky if not done properly. It is important to be cautious and avoid excessive straining when performing the maneuver to prevent potential complications.
The Valsalva maneuver also corrects some rapid heartbeats originating in the atria. When the maneuver is done correctly, blood pressure rises. This forces the heart to respond by correcting its rhythm and beating more slowly.
When performed formally, the patient is asked to blow against an aneroid pressure measuring device (manometer) and maintain a pressure of 40 millimeters of mercury (mm Hg) for 30 seconds.
From WikipediaThe Valsalva maneuver is performed by forcibly exhaling against a closed airway. Variations of the maneuver can be used either in medicine, as a test of cardiac function and autonomic nervous control of the heart or to 'clear' the ears and sinuses (equalize pressure) when ambient pressure changes, as in diving or aviation. The technique is named after Antonio Maria Valsalva, the 17th Century physician and anatomist from Bologna, whose principal scientific interest was the human ear. He described the Eustachian tube and the maneuver to test its patency (openness). He also described the use of this maneuver to expel pus from the middle ear. A modified version is done by expiring against a closed glottis. This will elicit the cardiovascular responses described below but will not force air into the eustachian tubes.

less formally, the patient may be asked to bear down, as if having a bowel movement. During this 30 second period, a recording is made of the changes in blood pressure and murmurs of the heart.
