APPARATUS AND METHOD FOR EUCAPNIC VOLUNTARY HYPERVENTILATION TESTING |
摘要 |
A method and apparatus provide more efficient eucapnic voluntary hyperventilation (EVH) testing by using a low pressure demand valve that has low resistance during rapid breathing and by monitoring air flow to the subject from a pressurized tank using measurements of change in the tank's pressure. A second stage Scuba regulator is modified to provide a demand valve that has low resistance during rapid breathing.
