Hi, I'm a EMT-Basic from Portugal.
The medical emergency units in Portugal are very similar to Spain, and other western european countries.
Our units are:
BLS ambulance (ambulância de suporte básico de vida): They are staffed by 2 EMT-Basic. They only can provide BLS and can not give drugs (except AAS by medic-control), can not intubate (just can use a oropharyngeal/nasopharyngeal tube) and just can use a AED.
ILS ambulance (ambulância de suporte imediato de vida): They are staffed by a registered nurse with experience in advanced life support, and a EMT-Basic. The nurse can provide a ALS, can intubate, can give drugs (emergency drugs and pain drugs like fentanyl). They can start IV's, fluids, ECG recognition, they can use a manual defibrillator, and do pacing and cardioversion, ect, under medic control.
ALS vehicles- Resuscitation and Emergency Medical Vehicles (veículos de suporte avançado de vida - viatura médica de emergência e reanimação VMER): They are a real "mobile" intensive care unit. They are staffed by a emergency physician and a registered nurse with ALS experience. These vehicles are well equipped.
ALS- Helicopter (helicóptero de suporte avançado de vida): They are staffed by two pilots, a emergency physician and a registered nurse with ALS experience. They are equipped like a VMER and a ICU.
Pediatric and neonatal Advanced Life Support Ambulances: They are staffed by a physician, a registered nurse with PALS experience and a EMT-B. They are equipped like a neonatal intensive care units.
BLS motorcycle: They are staffed by a EMT-B. These motorcycles are used in a big citys with a lot and a massive traffic. The EMT-B can stabilize de victim, until de ambulance or a VMER arrives.
I'm a EMT-Basic here in Portugal. If you want, I can help you. Anyway, EMT-Basic just can provides BLS and AED. There is no paramedics here. Only doctors and registered nurses with ALS/ACLS/PALS experience can provide ALS.
