Guidelines now available from the UK Resuscitation Council:

http://www.resus.org.uk/pages/guide.htm

For adult BLS they now recommend as follows:

The following changes in the BLS guidelines have been made to reflect the
greater importance placed on chest compression, and to attempt to reduce the
number and duration of pauses:
1) Make a diagnosis of cardiac arrest if a victim is unresponsive and not
breathing normally.
2) Teach rescuers to place their hands in the centre of the chest, rather
than to spend more time using the 'rib margin' method.
3) Give each rescue breath over 1 sec rather than 2 sec.
4) Use a ratio of compressions to ventilations of 30:2 for all adult victims
of sudden cardiac arrest. Use this same ratio for children when attended by
a
lay rescuer.
5) For an adult victim, omit the initial 2 rescue breaths and give 30
compressions immediately after cardiac arrest is established.
