実験的：F(40), then Saline, then IV.F
On Test Day 1, participants received Aerosol Furosemide 40mg in 4ml saline by inhalation for 5-10 minutes. On Test Day 2 (at least 24 hours after Test Day 1), participants received Aerosol Saline 4ml by inhalation for 5-10 minutes. On Test Day 3 (at least 24 hours after Test Day 2), participants received Furosemide 15 mg diluted in 10 ml of saline by intravenous delivery for 5 minutes. |

メジャーの説明 |
時間枠 |
|---|---|---|
|
Subject Rating of Breathing Discomfort (Dyspnea)
時間枠：The breathing discomfort ratings were taken as an average of all ratings during runs before intervention and the first two runs after intervention. The 1st and 2nd post-runs began (on average) 12 minutes and 49 minute after intervention, respectively.
|
Change in breathing discomfort (dyspnea) rating at benchmark PETCO2 using a visual analog scale.
The change in breathing discomfort is expressed as units on a 0% to 100% continuous scale, where higher values represent more dyspnea.
The change is represented as the rating of breathing discomfort after the intervention minus the rating of breathing discomfort before the intervention.

Multidimensional Dyspnea Profile
時間枠：Measured before intervention
|
Characterization of subject's response to laboratory dyspnea model.
Data are from a baseline pre-treatment test on the first drug or placebo treatment day for the subjects used in the main analysis.
Subjects were asked to complete the MDP with reference to the last 30 sec of each run.
To weigh subjects equally, we selected one run from each subject: the first run that terminated in a rating of overall breathing discomfort (A1) of 50 to 90% of full scale.
The units of measurement are expressed as units on a 0 to 10 scale measuring intensity of a given quality, with higher values indicating greater intensity and 10 representing maximum perceived intensity.

Urine Output
時間枠：Cumulative urine output 1 hour after intervention
|
Diuresis is an expected effect of furosemide.
To the extent that aerosol furosemide is absorbed into the blood, diuresis is an expected 'side effect' of this treatment
|
Cumulative urine output 1 hour after intervention
