The uptake of Oxygen from the air is the essential purpose of respiration.
Oxygen supplementation in patients with breathing dificulties increases levels in the blood and decreases resistance to blood flow in diseased lungs, easing the workload on the heart.
I chose Oxygen as it seemed to offer the best opportunity to make a film with a simple human story. Myself and Guy King, the researcher, were invited onto a ward dealing with severe respiratory conditions in a London hospital and the first person we were introduced to was Bob. The hospital staff clearly liked him and I immediately understood why. Despite his desperate medical condition, he was extremely optimistic, remarkably kind and not without a sense of humor.
After a little consideration, I decided to shoot the film with Bob over one long night. I decided just to be there and experience something of his situation without any tricks, complicated structural considerations or big narrative ideas.
David Katznelson (cinematographer) myself and Guy stayed at Bob's flat all night, sleeping in the room next door so we could shoot him waking up. As we packed our kit in the morning, Bob couldn't thank us enough for taking an interest in him and his life.
