1. A nasal respiratory device for inducing positive end-expiratory pressure adapted to be secured in communication with a nasal cavity comprising:

  • a passageway, an airflow resistor in communication with the passageway, wherein the airflow resistor is configured to have a non-zero threshold pressure for opening during expiration so that the airflow resistor is closed during expiration when the pressure across the airflow resistor is below the threshold pressure for opening, but the airflow resistor opens during expiration when the pressure across the airflow resistor exceeds the threshold pressure for opening during expiration; and

    a holdfast configured to secure the airflow resistor in communication with the nasal cavity without covering the subject'"'"'s mouth.
