Outcome Measures

Primary Outcomes (1)

  • Measurement of pulse arrival time in patients with obstructive sleep apnea syndrome.

    The goal of this study is to collect pulse arrival time data as a means for the assessment of upper airway obstruction.

    4 - 8 hours

Secondary Outcomes (1)

  • Non-invasive Photoplethysmographic (PPG) measurement in patients with obstructive sleep apnea syndrome.

    4 - 8 hours

Study Arms (2)

Measurement of PPG waveforms

EXPERIMENTAL

Collection of photoplethysmograph(PPG)waveform data from patients with obstructive sleep apnea for 4-8 hours

Device: Measurement of PPG waveforms

Measurement of Pulse Arrival Time (PAT)

EXPERIMENTAL

Collection of PAT waveform data from patients with obstructive sleep apnea for 4-8 hours

Device: Measurement of Pulse Arrival Time (PAT)

Interventions

The ViSi Vital Signs Monitor will measure PPG waveforms for 4 hours.

Also known as: ViSi Monitor
Measurement of PPG waveforms

The ViSi Vital Signs Monitor will measure PAT waveforms for 4 hours.
