No results posted yet for this study

Summary

The primary objective of this study is to utilize the Airofit device to systematically measure and characterize the changes in intraocular pressure across its six different levels of forced expiration. This investigation will provide crucial quantitative data on the IOP-respiratory effort relationship, enhancing our understanding of IOP dynamics during controlled respiratory stress and establishing a new, standardized paradigm for such research.

Conditions

  • Intraocular Pressure

Interventions

OTHER

Intraocular Pressure after forced expiration

The experiment will entail the acquisition of a total of seven intraocular pressure (IOP) measurements from each subject. * T0: Baseline (pre-intervention, resting). * T1: Immediately after 1 minute of forced expiration at Level 1. * T2: Immediately after 1 minute of forced expiration at Level 2. * T3: Immediately after 1 minute of forced expiration at Level 3. * T4: Immediately after 1 minute of forced expiration at Level 4. * T5: Immediately after 1 minute of forced expiration at Level 5. * T6: Immediately after 1 minute of forced expiration at Level 6.
