Summary
The purpose of the project is to estimate the air temperature in the lungs after a change from room temperature (25℃) to an environment with a constant temperature of 88-92℃ in resp. lung-healthy persons and persons with bronchiectasis.
Detailed description
Heat is a widely available therapeutic modality and is often used for recovery after physical activity and pain treatment, and sauna bathing is a form of whole body thermotherapy ranging from 80-100 ℃ and low humidity of 10-20%. The heat load in a sauna has been shown to activate several beneficial physiological effects, and no adverse effects on the lungs have been demonstrated. It is unknown how much the air temperature in the lower respiratory tract (bronchial tree) in humans rises to under surroundings of 88-92℃. This is an observational, clinical trial investigating the changes in air temperature at different bronchial segments in both lungs under surroundings of 88-92℃ resp. in lung-healthy persons and persons with bronchiectasis.

| Type | Name | Description |
|---|---|---|
| OTHER | Temperature-measurement in lungs under sauna bath | Through a bronchoscopy procedure under an 88-92℃ environment, the air temperature is measured in the 1st, 2nd and 3rd bronchial segment, at 4th and 5th bronchial segment and at 6th-10th bronchial segment in resp. the right and left lung. The temperature is measured at time: 0 seconds (s), 15 s, 30 s, 45 s, 60 s, 75 s, 90 s, 105 s, 120 s, 135 s and 150 s. |
