Abstract: According to one aspect of the present invention, an aerosol inhalation system includes a first conduit member for delivering medication in the form of aerosol particles to a patient. The system also includes a first device in fluid communication with the first holding chamber for producing the aerosol particles and being sealingly yet releasably received within an adapter that forms an entrance into a first holding chamber. The adapter has a compressible material disposed thereon which is at least partially compressed by insertion of the first device to form the seal between the first device and the adapter, thereby creating a closed system that is therefore capable of delivering a fixed concentration of the medication to the patient due to a valve of the valve mechanism being closed when the patient inhales and the medication is delivered to the patient.

Abstract: In one embodiment, the invention provides a device for decreasing intracranial or intraocular pressures. The device comprises a housing having an inlet opening and an outlet opening that is adapted to be interfaced with a person's airway. The device further includes a valve system that is operable to regulate respiratory gas flows through the housing and into the person's lungs during spontaneous or artificial inspiration. The valve system assists in lowering intrathoracic pressures during each inspiration to repetitively lower pressures in the venous blood vessels that transport blood out of the head to thereby reduce intracranial or intraocular pressures.

Abstract: In one embodiment, the invention provides a medical method for treating a person and comprises repeatedly compressing the person's chest. While repeatedly compressing the person's chest, the method further includes repeatedly delivering a positive pressure breath to the person and extracting respiratory gases from the person's airway using a vacuum following the positive pressure breath to create an intrathoracic vacuum to lower pressures in the thorax and to enhance blood flow back to the heart.

Abstract: An arrangement and method is provided for controlling operational characteristics of medical equipment. A pressure sensor associated with the caregiver is arranged to sense changes in air pressure that correspond to breathing activity of the caregiver. The pressure sensor may comprise a neckband, headset, or the like. In the arrangement shown, a headset that is worn by the caregiver includes a disposable tube connected to a pressure transducer such that the pressure sensor senses changes in air pressure in the tube. An open end of the tube is positioned near the mouth of the caregiver to receive changes in airflow from the caregiver's mouth. The pressure sensor is in communication with a controller associated with the ventilator. The controller is arranged to control at least one operational parameter of the ventilator, such as the delivery of respiratory support to the patient pr actuation of an oxygen flush valve on the ventilator, based upon the changes in air pressure sensed by the pressure sensor.
