Measure
Baseline Followed by Intervention
Subjects randomized to perform baseline measurement of clearance on study day 2 and measurement of clearance with nasal delivery of heated and humidified air on day 3. Study days are separated by 4-7 days nasal delivery of heated and humidified air: Subjects will receive nasal delivery of heated and humidified air (plus oxygen if needed) at 30 liters/minute from the Fisher and Paykel myAirvo2 heater/humidifier using an Optiflow nasal cannula for four hours
Intervention Followed by Baseline
Subjects randomized to perform measurement of clearance with nasal delivery of heated and humidified air on day 2 and baseline measurement of clearance on study day 3. Study days are separated by 4-7 days. nasal delivery of heated and humidified air: Subjects will receive nasal delivery of heated and humidified air (plus oxygen if needed) at 30 liters/minute from the Fisher and Paykel myAirvo2 heater/humidifier using an Optiflow nasal cannula for 4 hours.
