Any person who engages in any form of breathhold diving is in danger of shallow- water blackout (SWB) i.e. the sudden loss of consciousness caused by oxygen starvation. Any breathhold diving results in some nitrogen build-up in the blood and other fast tissues. Due to the short time spent at depth this build-up is generally not signifi cant. Therefore, provided the effort involved in freediving has not been severe, there is little risk in diving after breathhold diving. However, the converse
