Hey everyone! Very recently I left MedSurg after 7 years for critical care. Thank goodness I have years of experience and knowledge of what "normal" assessments are. So far things are going very well. Titrating pressors,... Read More

    ICU faq's is my #1 site for easy to understand critical care info, written with a sense of humor.

    Great resources under Tracheostomy and Vent Information-- Info on peds and adults vent care

    Anybody- please offer your opinions as to why, really, so many thousands of people in this country are being kept alive by ventilators. And please, by all means - cut my head OFF before you ever contemplate giving ME a tracheotomy. IMO it's a fate far worse than death. It makes me squeam to think about. It's just too gross for normal conversation. And I've had more than one trach disgorge an unholy amount of secretions onto me, my uniform, my hands, and etc. Eegads.

    I keep seeing this on the side under "Liked Nursing Topics" and can't understand why someone doesn't understand vents. It's just ranting for goodness sake! What is there to understand??

    What? You mean nurses VENT? Don't they even care about their patients? If you need to vent why did you ever go into nursing in the first place? Don't you know there are a million new grads who'd kill for your job???

    at the last 2 posts!

    vanilla bean, Esme and NRS and PPs gave some great advice and links...helped me out a TON as a refresher when learning about vents in a critical care.

    When I started out, part of my orientation was shadowing a RT...it REALLY help put it all together. Hope you get a chance to grab one!

    Here are the Basics
    Ventilation is just like understanding I&O's, to much or not enough will cause problems

    Normally we breath by negitive pressure, when a person is intubated the cuff/balloon on the tube seals the airway so you can ventilate them with positive pressure.

    When a patient is on a vent you are managing there breathing, sedation your friend

    Vt= how big a breath, both to little and to much will cause problems, how big a breath depends on the disease process.

    Rate, to fast and to slow hyper & hypo ventilation

    AC = all the time, every breath the patients gets is what the vent is setup for
    too slow= hypo ventilation increased Co2, to fast = hyper ventilation

    Simv= sometimes, part of the breaths are AC (see above)and part of them are
    spontaneous, how big of a breath depends on Pressure support = helping taking a
    breath, to small, not enough support = hypo ventilation, to much help/ support =
    hyperventilation.

    Peep = 5 of peep changes your base line end pressure from 0 to +5, peep is use for
    oxygenation, recruitment of alveoli , to much peep can cause decreased cardiac
    output

    Cpap/Peep + PS pressure support, every breath is spontaneous, totally patient driven.
    To high of a Respiratory Rate and or to much Pressure Support = hyper ventilation
    To Low of a Respiratory Rate and or not enough Pressure Support = hypo
    ventilation

    Lung compliance, low lung compliance = stiff lungs, hard to ventilate, higher peak
    pressures. High lung compliance = soft lungs, easy to ventilate, lower peak
    pressures. High Peak Pressure = lung injury

    ABGs on the ventilation side PH and Co2 have an inverse action to each other
    High Co2 = Low PH, hypo ventilation, Low Co2 = High PH, hyper ventilation
    On the metabolic side you have Bicarb = buffering system, you can tell a lot about
    respiratory status base on the bicarb, acute, partly compensated, not
    compensated

    Rule # 1 NEVER stand at the foot of the bed, if you do you are just asking to be sprayed
    Rule # 2 Treat every trach as if they are Dirty, MRSA and mmmmmmm the smell of pseudomonas.

    why, sometimes it a personal choice, ease of weaning off the ventilator, people can have normal lives and have a trach. Most of the time family cant let there love one go, some will call it selfish of them or loving, some time it just torture.
