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 |
