The valsalva maneuver can dangereously increase blood pressure?

The valsalva maneuver can cause a transient increase in blood pressure, however, it is generally not considered dangerous unless there are underlying medical conditions or certain situations where it is not recommended. While the maneuver may temporarily raise blood pressure, it usually returns to normal levels within a few seconds. However, individuals with certain medical conditions such as severe hypertension, aortic aneurysm, or unstable cardiovascular conditions should consult a doctor before performing the valsalva maneuver. Additionally, in some situations such as scuba diving or during heavy lifting, the valsalva maneuver should be avoided or modified to prevent potential risks. It is always advisable to speak to a healthcare professional if there are any concerns or uncertainties regarding the safety of performing the valsalva maneuver.
