People with respiratory conditions, such as asthma and chronic obstructive pulmonary disease (COPD), usually need breathing treatments to help them breathe freely. During breathing treatments, medications enter the lungs through either an inhaler or a nebulizer. Both are only available with a prescription.
Therapy control based on cardiopulmonary status
InactiveUS20050065567A1RespiratorsOperating means/releasing devices for valvesIntensive care medicineLung
Methods and systems provide an approach to therapy control based on assessment of a patient's cardiopulmonary status. Conditions sensed via sensors of an external respiratory therapy device are used to assess a patient's cardiopulmonary status. The respiratory therapy device sensors may be utilized alone or in combination with other sensors to determine cardiopulmonary status of a patient. Therapy delivered to the patient is controlled based on the cardiopulmonary status assessment. For example, therapy delivered to the patient may be initiated, terminated, and / or modified based on the assessed cardiopulmonary status of the patient. Cardiopulmonary status assessment, therapy control, or both, are performed by an implantable device.
