Summary

This study checks if smartwatches can accurately measure oxygen levels in people with pulmonary hypertension, a condition that affects the lungs and heart. Twenty adults will have their oxygen levels checked by a smartwatch, a finger clip, and a blood test at rest, after exercise, and while breathing low oxygen through a mask. The goal is to see if smartwatches are reliable enough for home monitoring.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Aged 18-years old and above. * Diagnosed with pulmonary hypertension by right heart catheterisation showing a baseline mean pulmonary artery pressure \> 20mmHg, PVR \>2 Woods Units. * Able to perform a six-minute walk test (6MWT) * Able to give written informed consent. Exclusion Criteria: * Peripheral arterial disease * Tattoos or skin markings which cover the dorsal wrist. * Resting SpO2 \<88% * Severe concurrent medical condition that would prevent participation in study procedures or with life expectancy \<3 months * Patients with bleeding disorders * Patients on anticoagulation * Except in circumstances where anticoagulation is given solely for historical perceived long term survival benefit for pulmonary arterial hypertension. This patient group could be given the option to come off their anticoagulation for 1 week prior to the study visit if they wished to take part in the study. It could then be restarted the day following the study visit providing there were no bleeding complications related to the arterial line.
