摘要
A pressurized breathing system enabling the execution of the Valsalva maneuver. A breathing mask has an inhalation valve and an exhalation valve. A Valsalva valve when in its normal position does not interfere with the regular performance of the system. When it is activated, it holds the exhalation valve closed. An exhalation effort of the wearer then accomplishes the Valsalva maneuver against the closed inhalation valve.
