The respiration of 16 supine subjects was monitored at sea level and at an altitude of 3,050 m. Breath shape was defined by inspiratory and expiratory durations [TI, TE] and volumes [VI, VE], total breath duration [Tt], and ventilation [.VE(=VE/Tt)]. Dynamic breath pattern analysis revealed that the chronological sequences of these variables often display large sustained oscillations. Depending on their relative phase the simultaneous oscillations in VE and Tt are "compensating" or "reinforcing… CONTINUE READING
