No results posted yet for this study

Summary

The aim of the study is to analyze the variability of plethysmography curve depending on the breath cycle (respiratory rate and tidal volume).

Conditions

  • Apnea
  • Circulatory; Change
  • Respiration

Interventions

OTHER

Respiratory rate

The participant alternates respiratory rates of 30, 15 and 7.5 breaths/min. Breathe each frequency for 2 minutes with a one-minute break.

OTHER

Tidal volume

The participant alternates tidal volumes of approx. 2, 1 and 0.5 litres. Breathe each tidal volume for 2 minutes with a one-minute break.

OTHER

Apnea

The participant simulates three apneic pauses lasting 1 minute with a two-minute break.
