In case of an out-of-range result, 1 repeat test will be allowed. If the readings are out- of- range again, the study participant will be excluded * Participant has a history or current condition characterized by airway hyperresponsiveness (eg, asthma, chronic obstructive pulmonary disease (COPD), pulmonary fibrosis, obstructive sleep apnea, pneumothorax, etc) at Screening and on Day -1 of each Treatment Period * Participant has contraindications for spirometry at Screening and on Day -1 of each Treatment Period (eg, history of myocardial infarction within 1 week, systemic hypotension, severe hypertension, significant atrial/ventricular arrhythmia, uncompensated heart failure, uncontrolled pulmonary hypertension, acute cor pulmonale, clinically unstable pulmonary embolism, history of syncope related to forced expiration/cough, history of cerebral aneurism, brain surgery within 4 weeks, recent concussion with continuing symptoms, eye surgery within 1 week, sinus surgery or middle ear surgery or infection within 1 week, presence of pneumothorax, thoracic surgery within 4 weeks, abdominal surgery within 4 weeks, late-term pregnancy, active or suspected transmissible respiratory or systemic infection, including tuberculosis within 4 weeks, physical conditions predisposing to transmission of infections, such as hemoptysis, significant secretions or oral lesions or oral bleeding; acute illness 5 days before Screening, upper respiratory tract infection in the 4 weeks before Screening) Part B: Study participants with mild asthma * Participant is taking a prohibited medication or has taken a prohibited medication as defined in the Protocol * Participant has a history of or current respiratory disease characterized by airway hyperresponsiveness excluding asthma (eg, COPD, pulmonary fibrosis, obstructive sleep apnea, pneumothorax, etc)

An AE is defined as any untoward medical occurrence, unintended disease or injury, or untoward clinical signs (including abnormal laboratory finding) in study participants, users, or other persons, whether or not related to the investigational medical device. This definition includes events related to the investigational medical device or comparator and events related to the procedures involved except for events in users or other persons, which only include events related to investigational devices.
