Abstract
A device is provided for controlling the nitric oxide levels within the lungs of a subject. The device comprises a detector for detecting the respiration cycle of the subject and a stimulator for applying an acoustic or vibratory stimulus to the subject. The stimulator is controlled in dependence on the detected respiration cycle. In particular, acoustic stimulation may be provided at the onset of inspiration. In this way, the nitric oxide flow can be controlled in a way to ensure that the paranasal nitric oxide is nearly fully inspired. This provides a higher nitric oxide concentration in the lung/alveoli.
Claims16
A device for controlling enrichment of nitric oxide levels within the lungs of a subject, comprising:
- a detector for detecting a timing of a respiration cycle of the subject, wherein said respiration cycle comprises an alternating occurrence of an inspiration event and an expiration event;
- a stimulator for applying an acoustic or vibratory stimulus to the subject;
- and
- a controller adapted to control the stimulator in dependence on the detected timing of the respiration cycle and/or an event of the respiration cycle, wherein the controller is further adapted to interpret the output signal of the detector to provide a prediction of the timing of the beginning of a next inspiration event of the respiration cycle, and wherein the controller is adapted to actuate the stimulator a predetermined period of time before the beginning of the inspiration event of the respiration cycle.

A method of controlling an acoustic or vibratory stimulator, comprising:
- detecting the timing of the respiration cycle of a subject, wherein said respiration cycle comprises an alternating occurrence of an inspiration event and an expiration event;
- applying a vibratory or acoustic stimulus to the subject,
- controlling the stimulus in dependence on the detected timing of the respiration cycle and/or an event of the respiration cycle;
- and
- providing the stimulus at a predetermined period of time before a predicted beginning of the inspiration event of the respiration cycle.
