An Interesting Breathing Pattern

Abd = abdominal RIP; C = central EEE channel; Chest = thoracic RIP; Chin = chin EMG; E = electrooculography channel; EEG = electroencephalography; EKG = electrocardiogram; EMG = electromyography; F = frontal EGG channel; HR = heart rate; LLEG = left leg EMG; IC-EKG = intercostal electromyography; M = mastoid EEG channel; O = occipital EEG channel; Pleth = pulse oximeter plethysmograph; PPG = pulse oximeter photoplethysmogram; Pressure = nasal pressure transducer; RIP = respiratory inductance plethysmography; RLEG = right leg EMG; SaO2 = arterial oxygen saturation; SnoreMic = snore microphone; Sum = chest and abdominal RIP; Them = thermistor.

Obstructive events and airflow limitations are greatest at a higher frequency and lower cycle interval. [...]lowering frequency and increasing cycle length are possible options to avoid the worsening of sleep apnea during stimulation. In that case, CPAP titration is best performed with the VNS turned off and then retested with the selected pressure while the VNS is turned back on (7, 8). [...]therapy should be managed on a case-by-case basis.
