Some resuscitation in Proud Mary, Colin, a problem (15)

I believe the answer is:

cardiopulmonary

I'm a little stuck... Click here to teach me more about this clue!

'some resuscitation in' is the definition.
Although both the answer and definition are adjectives, I don't understand how they can define each other.

'proud mary colin a problem' is the wordplay.
'problem' indicates an anagram.
'proud'+'mary'+'colin'+'a'='proudmarycolina'
'proudmarycolina' with letters rearranged gives 'CARDIOPULMONARY'.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
