I'm in the UK, so this information has a slant to it, YMMV...
Getting a first aid box from the supermarket / health and safety store normally comes with a basic booklet of stuff. Take an hour to read and memorise, and I would say that's first aid / biotech =1. Cost is £10
A "First aid at work" course is normally done in 2-3 days, so about 18 hours of training. It will cover cuts, blood loss, splints, immobilising victims, recovery position and CPR. I'd say that would get you to biotech 2. Cost is about £300
Going the St Johns Ambulance / first aid trainer and doing a couple of the courses there, each 2-4 days long (we have stuff like Automatic external defibrillator, Professional Drivers first aid, Cardiopulmonary Resuscitation, Anaphylaxis first aid, Paediatric first aid) would take up 12-24 hours per course, so between 24 and 84 hours more training, and I reckon would get you biotech 3. Cost would be about £300 per module.
At that sort of level, you should be able to cope with most incidents at work, your average car / motorbike crash, accidents at home etc, which sounds about right for a skill at 3. Training time in total is between 40 and 100 hours total, depending on the quality of the trainer, and how well you do at classroom learning of course.
To make the step up to a professional level in the UK, you need a big step up in commitment.
To work as a nurse, you need a degree in nursing and you must be registered with the Nursing and Midwifery Council (NMC). You’ll need to choose which of the four nursing specialisms (adult, children, mental health, or learning disability) you’d like to study. Nursing requires a high level of technical competence and clinical decision-making skills. To develop these, you'll spend half of your nursing degree on supervised placements in local hospital and community settings. (source=https://www.rcn.org.uk/professional-development/become-a-nurse)
A UK degree is 3-4 years of training, at about £10k per year in tuition. But, that would give you a solid 4-5 in Biotech, and a whole bunch of related background / complimentary skills.
The next leg up, a Doctor, requires a medical degree, taking 4-6 years. Expect the course fees to be anywhere up to 50% higher, more if you go to a prestigious university. So, a much heftier increase in commitment, but rating 5-6 in the skill and a massive clutch of background skills to go with it. (https://nationalcareersservice.direct.gov.uk/job-profiles/paramedic)
If you were going for a narrower specialism - specifically the first aid side say, then a paramedic course requires only a foundation degree or Diploma of Higher education, so you're looking at 2-3 years training there. You don't get the breadth of knowledge, but a good specialism in the immediate roadside / scene care needed to transport to a facility.

As the poster above said, skillwires, chips, and other high tech methods would potentially change this massively. Real life and Shadowrun don't always go hand in hand well on stuff like this, as the skills tend to be a narrow focus, rather than the broad range of stuff a course normally imparts. But hopefully that will give you a yard stick to work from.
