研究概览
简要总结
The aim of the study is to investigate if the use of a handheld fan directed to the cheeks alongside conventional medical treatment partially or totally relieves breathlessness and if this effect lasts for at least 30 minutes in patients irrespective of the underlying disease process.
详细描述
A previous randomised controlled trial (Galbraith et al, accepted for publication) has shown a reduction in breathlessness after 5 minutes use of a fan directed to the cheeks. This study is a feasibility study to determine how long this beneficial effect lasts.
With the patient in a relaxed sitting position and ensuring there is no other fan or open window blowing air onto the subject, the following will be explained to the patient and then measured and recorded
- Numerical Rating Scale (NRS) for dyspnoea
- Visual analogue scale (VAS) for breathlessness with end anchors
- O2 saturation using pulse oximeter
- Pulse rate using pulse oximeter
- Room temperature and humidity recorded
The patients will be asked to avoid talking or significantly change position throughout the study.
Fan to cheeks The investigator will demonstrate to the patient how to use the handheld fan directed to the cheeks. The appropriate area on the face, which corresponds to the area innervated by 2nd and 3rd trigeminal nerve branches, will be demonstrated by the researcher. The patient will then use the fan as demonstrated and this will be timed for 5 minutes with the patient in a relaxed sitting position.
