METHODS OF TREATING A DISORDER BY INHIBITING EXPIRATION
First Claim
1. A method of treating a disorder comprising:
- placing a nasal device in communication with the subject'"'"'s nasal cavity, wherein the nasal device comprises an airflow resistor that inhibits exhalation through the nose more than it inhibits inhalation through the nose; and
securing the nasal device in communication with the subject'"'"'s nasal cavity without covering the subject'"'"'s mouth,wherein the disorder being treated is selected from the group consisting of;
sleep apnea, snoring, heart failure, pulmonary edema, cystic fibrosis, reflux disease, asthma, hiatal hernia, hypertension, cardiac valve disease, and Barrett'"'"'s esophagus.

Abstract
Described here are devices for altering the flow of air in a respiratory cavity such as the mouth and nostrils of the nose. These methods and devices may be useful for affecting a physiologic benefit in patients suffering from a variety of medical diseases, particularly those that may benefit from “pursed-lip” breathing and non-invasive ventilation, such as COPD, heart failure, sleep apnea, and other medical disorders. The devices are typically removable devices that may be placed over or in a respiratory cavity to increase resistance to airflow within the respiratory cavity. Resistance to expiration may be selectively increased relative to inspiration. Removable oral and removable nasal devices are described. Oral and nasal devices that filter inhaled airflow of debris and allergens are also provided. A nasal device that increases patency of the nares is also provided.

8. A method of treating a subject, the method comprising:
-
securing a nasal device in communication with the subject'"'"'s nasal cavity without covering the subject'"'"'s mouth, wherein the nasal device comprises an airflow resistor that inhibits exhalation through the nose more than it inhibits inhalation through the nose, the nasal device comprising a holdfast, and further wherein the nasal device is secured in communication with the subject'"'"'s nasal cavity so that the holdfast is at least partly outside of the subject'"'"'s nose; and increasing the resistance to exhalation through the nose more than the resistance to inhalation through the nose to treat the subject. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
