Eligibility Criteria Checklist

Specific guidelines that determine who can or cannot participate in a clinical trial

Must have

Be older than 18 years old

Timeline

Screening 3 weeks

Treatment Varies

Follow Up 4 serial dynamic inspiratory capacity maneuvers for each minute of the 4-minute constant rate treadmill test.

Summary

This trial will explore how fan-to-face therapy helps with breathlessness during exercise in people with cardiorespiratory disease.

Who is the study for?

This trial is for people who feel breathless during exercise despite treatment, with a BMI between 18.5 and 35, cleared for physical activity by a doctor, and diagnosed with cardiopulmonary diseases like COPD or heart failure. It's not for those who've changed medication recently or had an exacerbation/hospitalization in the last six weeks.

What is being tested?

The study tests if blowing cool air on the face using Honeywell HT-900 Turbo Force Air Circulator can relieve shortness of breath during constant-rate exercise in individuals with cardiorespiratory disease. The aim is to understand how this simple intervention works physiologically.

What are the potential side effects?

Since the intervention involves non-invasive use of a fan to circulate air, there are no direct medicinal side effects expected from this trial. However, participants should be monitored for any discomfort or adverse reactions related to airflow exposure during exercise.

Experimental Treatment

Active Control

Placebo Group

Group I: Fan-to-faceExperimental Treatment1 Intervention

The participants will complete a 4-minute constant work rate treadmill test with a basic, portable fan placed in front of the face. The fan will be placed at a location to target the second and third branches of the trigeminal nerve and will be placed a distance chosen by the participant so that the airflow speed is comfortable.

Group II: No fanActive Control1 Intervention

The participants will complete a 4-minute constant work rate treadmill test with no fan.

Group III: Fan-to-legPlacebo Group1 Intervention
