Handheld pressure support system for treating hyperinflation

Abstract

A portable handheld pressure support system (10) is configured to provide pressure support therapy to a subject. The pressure support system provides a pressurized flow of breathable gas that is delivered to the airway of the subject to treat COPD and / or dyspnea, hyperinflation, and / or other conditions. The system is configured to adjust an expiratory pressure level of the pressure support therapy responsive to identification of hyperinflation in the subject. The pressure support therapy provided to the subject is configured to be used as needed to rapidly alleviate shortness of breath, hyperinflation, and / or other symptoms. The pressure support system is configured to be small and lightweight so that the subject may carry the system and use the system as needed.

[0003] The present disclosure relates to a portable handheld pressure support system configured to deliver a pressurized flow of breathable gas to the airway of a subject. Background technique

[0004] Positive air pressure (PAP) can be applied to the patient's airway to keep the airway open and avoid collapse during breathing. This positive pressure effectively "stretches" the airway, thereby maintaining an open pathway to the lungs. Difficulty breathing, or shortness of breath, is a major symptom of chronic obstructive pulmonary disease (COPD). COPD patients may also experience hyperinflation. COPD patients suffer from dyspnea and / or hyperinflation as they exert their full strength. Forms of exertion ca...
