Project Title: Study of the effects of vitamin C on the lungs
Participants are needed to take part in experiments that involve coming to the physiology laboratory
in Oxford, or the Altitude Centre in London, for two days separated by at least one week. The study
involves measuring the body’s responses to breathing a reduced level of oxygen, similar to in the
mountains (about 4,300 metres altitude) after receiving vitamin C, and comparing these responses
to those with no vitamin C. We are particularly interested in studying the blood pressure in the
lungs using heart ultrasound.

Potential participants should be adults who are not pregnant and are in good health.
Participants will be reimbursed at £10 per hour for all time spent in the study (likely to be about 16
hours) and for travel expenses incurred.
