Airflow restriction systems are described herein which may be used to treat various disorders by creating expiratory positive airway pressure while providing for patient comfort regardless of the patient's anatomical variances. Such a device may be removably secured externally over the patient's nose rather than within the nasal passages to increase patient comfort. The restriction device may be secured, e.g., via an adhesive, to the patient and actuated via any number of mechanical or electromechanical mechanisms. Moreover, the restriction device may include one or more sensors to detect the patient's respiration activity such that the device may be actuated to correspond to the patient's exhalation and squeeze or otherwise constrict the nasal passages at least partially by pressing against the exterior surface of the nose to restrict the expiratory airflow.

The invention features methods for preventing platelet activation and aggregation and for treating individuals suffering from conditions or undergoing procedures that may result in unwanted platelet aggregation. The methods are based on the intravenous, subcutaneous, or transdermal administration of a platelet activation or aggregation inhibitor, e.g., xemilofiban, followed by oral administration of the same or a different platelet activation or aggregation inhibitor. The treatment may commence prior to a medical or surgical procedure or after the outbreak of an adverse medical condition, either of which results in the activation of platelets that may lead to thrombus formation, and may continue thereafter.
