Abstract: A spirometer comprises a housing defining a fluid flow pathway extending between a first end and a second end, a first opening along the pathway and a second opening longitudinally spaced along the pathway from the first opening. A flow chamber defining a fluid flow pathway is disposed within the housing between the first opening and the second opening, the flow chamber including an elongated resistive element along the central longitudinal axis of the flow chamber for defining a flow passage through the flow chamber between the resistive element and the inner surface of the flow chamber. The flow chamber conditions fluid flow for accurate sensing of the fluid flow over a range. A pressure sensor is disposed within the housing in fluid communication with the first opening and the second opening for sensing a pressure differential between the first opening and the second opening and producing an electric signal that corresponds with the rate of fluid flow through the housing.

Abstract: Systems and methods for processing mobile patient-centric electronic health record data. In one example, the system and method perform or include storing, with a memory in a computing device associated with the patient, a core module associated with the electronic personal health record having personal health information of the patient; assigning, with an electronic processor, permission rights to the personal health information of the patient; receiving a report query for personal health information from a server associated with a service provider; determining the service provider has permission to access the personal health information of the patient; retrieving personal health information from the electronic personal health record in response to determining the service provider has permission to access the personal health information of the patient; and sending the personal health information to the server associated with the service provider.
