Background:
Provision of healthcare from a remote site may assist patients to access important services. We aimed to establish the feasibility of monitoring an assessment of exercise capacity using telehealth technology.
Methods:
Adults with CF completed two 3-min step tests, monitored in-person or remotely via videoconferencing, in randomized order. Measurements were physiological responses to exercise, system usability, ease of clinician interaction, metronome acoustics, and participant comfort.
Results:
Ten adults (5 male), mean ± SD age 32 ± 7 years, and FEV1 55.4% of predicted (range 38-90% of predicted), completed both tests. Participants reported good system usability, with a mean (95% CI) System Usability Scale score of 85.63 out of 100 (79.8-91.5). Metronome acoustics were rated as significantly poorer remotely (P = .006). There were no differences in measurements of oxyhemoglobin saturation or heart rate between assessment settings.
Conclusion:
Exercise capacity assessment using the 3-min step test is feasible and accurate via remote videoconferencing in adults with CF.

Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
Purposes
Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
