Bilevel
Basal respiratory mechanics in spontaneous breathing will be analyzed by optoeletronic plethismography (OEP), followed by bronchial provocation with hypertonic saline solution 4.5%, another 45-second OEP uptake, IPAP 12 and EPAP 8 bilevel applied for 10 minutes, and a new uptake. All abstractions are preceded by a forced and slow spirometry maneuver. The entire procedure takes 1 hour.
Albuterol
Basal respiratory mechanics in spontaneous breathing will be analyzed by optoeletronic plethismography (OEP), followed by bronchial provocation with hypertonic saline solution 4.5%, another 45-second OEP uptake, 400 micrograms inhaled Albuterol, and a new uptake. All abstractions are preceded by a forced and slow spirometry maneuver. The entire procedure takes 1 hour.
