rghbsn gives great advice and you got some well worn answers at FW as well.
I'll add - you appear to have a solid background, so that is an excellent starting point. If I am reading correctly you seem to have a year of RN experience and maybe a decade or so of fire based EMS as a paramedic. If that is correct ??? You are on the right path. I appreciate that you have a manger willing to recommend you - a good rep is golden! Keep it! You need to have a few more years experience (2-4 minimum).
There are many answers that outline the value of ED vs. ICU experience here and on FW. I don't have too much to add except --- you are out there with a partner that is a paramedic. You will be expected to bring the "nurse" expertise and unless you have some vastly differing experiences you/your partner will be in over your head from the get go. Not a comfortable or IMO even acceptable place to be.
Not sure of the geography (TX or FL maybe AL), but do some "informational" interviews with the flight companies in your area. Most are looking for exceptional folks and will give you an idea where you stand. If you are willing to relocate to get a chance to fly with certain companies - look at the "mission profiles" of those outfits as well. Maybe some introductions to a flight crew or two may informally give you an idea how to compare in education/experience and the ever important alphabet soup factor.
I could puff you up and tell you that you can fly right away and everything will be okay - and you likely could as the medic
depending on the quality of your medic experience and the mission profile
of the flight company. If you simply must fly right away - just be prepared to do it as the medic part of the team for now. This does not imply any lack of ability - just an observation that the "effective team" has some synergy and the nurse must wear the "high end" critical care hat to the party.
Some medics do true CC transport and if that is you - woohoo! & you are so ahead of the game. IMHO these medics are quite rare.
One problem that I have had some unpleasant experience with is, in fact, the experience problem. You will find that some companies will require minimums for nurse or medic with 3 years each. The issue gets muddled when both have the bare bones minimum - the medic has been a medic three years and the nurse has three in the ED - these two become a team and disaster looms. Trust me and take this point with you - you DO NOT want to be in this spot and avoid working for any service that has teams comprised of the "bare minimum".
Most companies "bread and butter" flights are the transfers - IFT from lesser care to higher or more specialized tertiary care. Even the "scene" stuff in some areas includes strokes and STEMI's. Having some high end critical care experience is going to save the patient
and save you and your partner
. Depending on the flight program you may have some advanced procedures (inserting central lines, arterial lines, true chest tubes, etc) but these are skill based and can be learned; the indications and physio associated with these procedures (along with ventilator management/complex medical drips/balloons) - when, how and why they are used are what will be the vital role of the critical care RN. Example: imagine having never worked with art lines because you only have ED experience and then learning to insert and troubleshoot/manitain and monitor after being hired to fly or managing the complex ARDS patient all the while paired with a medic partner that has never even routinely programmed a IV pump for a dopamine gtt. Not just frustrating - but flat out dangerous. I'd like to think that flight programs that do critical care hire the cream of the crop, but the flight industry has grown rapidly and well, the quality of the "crops" can vary.
I guess my take away point is - get some really high end critical care experience. Mix this CC experience up and really challenge yourself.
Keep you foot in the ambulance
and your nose to the grindstone for a few more years. I am not trying to discourage you, just hoping to give you a snapshot of the realities (some harsher than others) that the under-prepared will face. I want you to avoid that. Sure, flying is cool and all that - but, it is just a way to get an often really sick patient from point A to B. It is a job and has inherent risks and challenges (this year has been less deadly, but 28 of my colleagues died last year) - so, be sure.
Your background is great. Plan for your CEN. Get that CC experience and after you are eligible sit for the CCRN. I say hold on the CFRN - as you do not fly now, so being certified as a flight speciality nurse when you are not working in that area IMHO muddies what board certification is all about - wait until to you are actually flying to specialize.
Be a wicked determined clinician and seek out the tough cases and use any PITA factor necessary (to a point) to learn from the best doc's and nurses and RT's that you can find to help you in your knowledge quest! Read extensively and work to add depth to your clinical practice. Sure, some places hold patients looking for a bed and some hold 'em until they have them so ****** that you will be lucky to get to the helipad with 'em alive. I really wish that I was bluffing on that one - but, I am sadly not. (Even the simple ones can be pucker worthy!) Be ready for anything!!!
Join ENA and ASTNA. You are on the right road - I just want to get you pointed to the right direction in the sky.
Best of Luck. PM if I can help further.
