Abstract

Devices and methods for delivering air to a patient are provided. A device includes a first portion having a first airflow inlet and a sensor configured to sense airflow, the first portion defining a first airflow path, and a second portion comprising a second airflow inlet, an impeller, and an outlet for communicating airflow to a patient, the second portion defining a second airflow path. The device includes means for coupling the first portion and the second portion, such that the sensor sensing airflow in the first portion causes corresponding movement of the impeller, wherein the impeller is configured to impel air through the second airflow inlet and out of the outlet to the patient, upon movement of the impeller.
