The Emergency Therapy Index

Not the endangered state of a patient (diagnostic aspect, possibly without the therapy which is required) but the treatment, what is actually done for the patient, should be graduated in order to describe the value of a rescue service. For this purpose, the ETI was developed:
 

0

No medical examination or other measures 
    (includes termination of mission before arrival of the EP)

1

Determination of death without the EP's prior therapy
    (includes CPR through paramedics before the EP's arrival)

2

Medical examination without therapy

3

Prophylactical therapy  (e.g., anticonvulsive prophylaxis, i.v. line)

4

Therapy, not directed against vital threat (vital threat may exist)

5

Constant monitoring (medical surveillance) necessary due to 
   suspected threat to life (e.g., by entrapment only on-site) 
   or during transport due to potential dangers)

6

Therapy directed against vital threat to life or

6B

 risk of invalidity (e.g., spinal injury, amputation)

7

Endotracheal intubation and/or anaesthesia and/or operative 
   invasion (e.g pleural drainage)

7B
7C

Anaesthesia without intubation
Operative invasion without general anaesthesia

8

Defibrillation and/or cardiac massage before admission

9

Defibrillation and/or cardiac massage, death without admission
