Question: When administering CPR, what ratio breaths to compressions should you give?

Forfeit: 8:1, 15:2.

Answer: 30:2

Notes:
CPR is a vitally important form of first aid, if performed correctly it can save lives, keeping people alive until specialist medics arrive on the scene, however without the backup of medical equipment it is not nearly as successful as you might see on television.

When giving CPR any interruptions in chest compression decreases the chances of survival, and ideally a first aider would give continuous compressions while another gave ventilation, though obviously this is not always practical. After recent scientific evidence, the CPR guidelines have been amended, and the chest compression to ventilation ratio is now 30:2.

Also, here's a thing:

Question: You're in hospital: your heart stops, the Electro-cardiograph starts to beeeeeep and the line which signifies your heartbeat goes flat - what will the doctors do to get it going?

Forfeit:
They'll use those electric shock things.

Answer:
The doctor may inject you with a hormone called vasopressin.

Notes:
Despite what the telly says, defibrillators are not used to restart a stopped heart, they are used to regulate an irregularly beating heart.

An ECG will go "flat-line" if the patient suffers from asystole, or a complete stop of the heart's beating; there is no electical activity at all. Only a very small percentage of patients in this case will survive (c. 2% make it to discharge), a recent study has shown that the percentage success rate may be slightly improved by the hormone vasopressin.

'But ...'

'Yes, sir!'

Here's a study from the University of Queensland, which stakes a claim for injecting heart-attack drugs into the Corpus cavernosum* - an area where blood vessels are often in good supply.

*That's the erectile tissue in the penis, for the non-anatomists amongst us.

Researchers (that motly bunch) have found that injecting drugs into the backside may be becoming less and less effective with the increasing waistline.

Quote:
Injections given in the buttocks are unlikely to work because patients bottoms are too fat... For drugs to be effective, injections must be delivered into muscle which is supplied with microscopic blood vessels, to maximise absorption of the medicine. But the larger size of the average backside means the muscle is now covered with a layer of fat and the standard needles fitted to syringes are not long enough to penetrate it.
