  • APPARATUS AND METHOD FOR EUCAPNIC VOLUNTARY HYPERVENTILATION TESTING
    Publication number: 20120253218
    Abstract: 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.

  • Metering system for stimulating bronchial spasm
    Patent number: 4106503
    Abstract: A system for administering a metered dose of nebulized antigen tests a patient's pulmonary response. The system includes a thermistor detector for sensing initiation of patient inhalation. A variable electronic timer meters the amount of nebulized antigen introduced to the patient. Safety switching means is provided for insuring against erroneous administration of more than a single dose at a time. Separate measuring equipment is used to measure pulmonary airflow resistance which will increase in response to bronchial spasm.
