      CANAYAMD VC and PC are two different modes. They do have variations which add assist control for example ACVC+, ACPC, VOL/AF(seen on my anesthesia machine). But strict VC or PC have set values that do not assist a spontaneous breath. There is no pressure support setting on strict VC or PC. However you can assist with modes like SIMV, ACVC+, and of course pressure support. ACVC+ is essentially pressure regulated volume control, so you can deliver a set tidal volume with variable inspiratory pressure to account for changes in lung compliance thus hopefully minimizing your peak inspiratory pressures..hope I answered your question:)

      CANAYAMD 5 years ago +1

      mrfrizzle0782 I thought volume control and pressure control are modes of assist control. You are equating assist control to volume control. Know what I mean?

    This was great. I wish I had this available back in the day. Thank you for your time. I started out as an Oxygen orderly back in 1973 after I was discharged from The Marine Corps in New York City. Wheeling H tanks on a dolly with an adjustable wrench to the patients bedside and changing them out when they reached 500 PSI. No piped in Oxygen back then and only open patient Wards. with 10 to 15 patients in a room separated by a draw curtain.Part of my arsenal was a No smoking sign. It was not uncommon. to see patients smoking while lying in their beds as well as a doctor examining a patient with a cigarette dangling from the sides of his mouth. Oh how we long for the good old days LOL. I eventually became a certified inhalation therapy tech. Via The AARC later it became the NBRC or vice Versa. I stopped practicing in 1999 when I came to Massachusetts only to discover Massachusetts was a commonwealth and reciprocity of my licenses were never granted. I like to believe, I was a respiratory therapist and have been around since the Infancy of our profession. That makes me the original OG of respiratory therapy. Back in the days. We ran to codes with a Bird Mark 5 or mark 8 pressure ventilators
    ( the little green Box ) attached to an E-cylinder of Oxygen. The ideal settings on the Bird were 15, 15, 15. It was actually a great little machine to run to codes with. Easy to maneuver through patients wards and great during transports. Back then the big fear with the Bird was the infrequent incidence of Barotrauma as well as all the negatives associated with Positive pressure ventilators. However, if you knew what you were doing, You were golden.
    later in my career I became a clinical instructor and that became part of my introduction to my students. I would introduce myself and begin with these words
    ( Keep in mind. I am a United States Marine ) I would begin, If you are here to press buttons and turn Knobs. This is not a class for you. I can teach a Monkey to do that.
    However, if you want to know what happens mechanically and physiologically after you have pressed that button and turned that knob. Please have a seat.
    ( By the way, my students had the highest passing rate on certs and registry ) Back to the past.
    Back then, we had Engstrom and Emerson Volume ventilators with a heating plate at the bottom and a steel pot similar to a pressure cooker that sat on atop of the heating plate. The tubing ( AKA Manifold) contained steel wool lining the inside of the tubing to increase and help maintain the humidity of a dry gas. It had a huge mechanical spirometer. It sat on top with a large needle that move per cycle of respiration .
    One day, the workhorse came onto the scene. We all gathered around and received an Inservice on the latest and the greatest. The Puritan Bennet MA-1. followed by the 7200, the bear respirator, Etc. I could go on forever, so I will end here with these two memories. When PEEP was in its Infancy. Hell, it felt like we invented it. We would take a large bottle filled with water, placed alongside the respirator on the floor. We would submerge the tubings of the manifold into the bottle below the water level we would adjust the amount of PEEP by adding more water to the bottle or elevating or decreasing the height of the submerged tubing into the water. This is how PEEP. started out. ( Positive End Expiratory Pressure. prolongs exhalation. Thereby allowing the Alveoli to remain open longer and allowing for a prolonged period of Diffusion along the Alveolar Capillary membrane ) Somethings you never forget LOL
    If you took the time to read this. Thank you for allowing me to share with you a trip down memory lane. Trust me there is a lot more to share as my career span was well over 35 years working in diverse clinical settings and adult critical care. To include having the honor of being part of Mount Sinai's School of medicine and working as a pulmonary research technician alongside Dr. Irving Sellikoff ( asbestosis and Sarcoidosis studies) Dr.Alvin Tierstien and Dr. L.K Brown. Traveling the country back in the 80's as part of a research team to predominately gay communities and seeing well over 100 patients a day and performing PFT's and Perfusion studies when patients at that time were expiring in NYC and the diagnosis at that time was " Fever Of Unknown Origin " ( AIDS) Going into the Tunnels of the NYC Subway system with a team to locate and perform sputum inductions on the homeless. At that time, we had a strain of drug resistant TB.
    Then I moved to Mass and my carrier came to an abrupt halt because of Bureaucracy. "Sie La Vie" . I am a U.S. Marine. We are trained to adapt and overcome.
    I fell back on the trades. In the Marine Corps, I was formally trained as a Lineman and electrician as well as an Avionics tech.( Aircraft electrician ) At Marine Corps engineer school. Courthouse Bay N.C.
    My mechanical aptitude I believe was why I was able to teach my students and reach them in a mechanical way. I would equate the human body in its purist form. A machine and in a mechanical way. The neuron pathways are no more than a glorified electrical conductor ( wire ) picture the wiring in your home. It has copper and the insulation that surrounds the copper coil is made of a rubber non conductive material.
    A neuron for all intents and purposes is a wire and it's insulation it is the Myelin sheath. The heart, a four chamber pump. Positive and negative pressure outputs with valves that open and close and seal etc.
    I miss my career, I miss my patients, I miss being able to have that feeling after all is said and done. Watching that patient and his family go home together.
    However, I was able to vicariously share with you a very small part of the evolution of Respiratory Therapy from a first hand eye witness.
    This is the OG of Respiratory therapy saying Thank you again and Semper Fi.

    The concepts are explained so beautifully and in such simple terms! It takes a genius to explain such complex things to a layman so Medcram guys - you are geniuses! Else any medical technician/doctor can pepper the entire talk with jargon and screw up one's interest in learning the concepts.

  • Douglas Miles
    Douglas Miles 7 years ago

    First, thank you so much for sharing your knowledge and making it understandable to the novice. Although I can't put most of your instruction to practical use in my own job, I appreciate the insight it gives me into the challenges you face in the hospital setting. Quick question, am I missing something or did you not touch on SIMV mode? I watched all 5 parts and if you covered it, I must have zoned out. When you described AC, it sounded like SIMV with the patient triggering the breaths as opposed to CMV breaths being vent-triggered. I realize the videos are finalized, but could you explain (as you do so eloquently) the mechanical difference between SIMV and AC mode? Thank you!

    • Irate Wasp
      Irate Wasp 7 years ago +2

      AC mode will deliver a consistent volume when the patient triggers a spontaneous breath, hence the "Control" in Assist Control. SIMV will still give the patient a set number of controlled breaths, but the patient triggered breaths (spontaneous) will be as big or small as the patient makes them (not controlled). AC = vent controlled spontaneous breaths while SIMV = patient controlled spontaneous breaths.

    AC might be called Pt Initiated. Compliance is the inverse, or complement, of inflation Resistance(ie due to fibrosis, obesity, or fluid collection). The various alarms(vol, rate, pressure, pCO2-out, pO2-out, etc.) should always be set, & tailored for near normal respiration, in case the patient's respiratory performance changes for the worse.

    Excellent especially for students and doctors from non English speaking countries. The usual video tutorials given by native English speakers is with heavy accent and difficult to comprehend and causes lots of stress trying to make out what the speaker is trying to say. But your accent is so clear, slow, English is so simple and you have done fantastic service to students from third world countries. Even a layman can understand your lectures. If the patient care improves because of your lectures,(I am sure that it will) the credit actually goes t o you.

    I have been watching your videos since the start of Covid, and now my mother has been placed on a ventilator for her COPD. She was diagnosed 10years ago when she started hallucinating and got very sick, she was not releasing carbon dioxide, from then she slept with a bipap, she recently got bronchitis and ended up on a ventilator, when they take her off her blood gasses show too much CO2. Now they want to put it in through her throat. Would she be able to come off the ventilator permanently in the future? From what I have read it seems like she won't survive this for long? I'm stuck in another country because of Covid and I am beside myself with worry. Do you know of patients that have recovered after going through this? Please help me, she is my whole world 🥺

    I was told by a Doctor and many ICU nurses that putting a patient on a ventilator was fraught with many dangers especially for the elderly patient. Not that the equipment would fail to sustain homeostasis, but while ventilated it provides many a patient with a path way for a pseudomonas infection which usually requires both a gram positive antimicrobial and a gram negative antimicrobial, e.g. Imipenem and Amikacin given together in the right amounts. However, if they survive that; I was told the biggest hurdle was successfully getting them off the ventilator to sustain breathing on their own once off of the machine. I can recall where a family had to make the decision whether or not to ventilate their elderly Grandmother. Their Doctor who was also my Mother's Doctor was recommending that they don't do it and take their chances for the survival of their Grandmother without its use. However, they chose to ventilate her. At first after she got off the ventilator she appeared to be in good health and it looked as though she was going to make it. But without any warnings she took a sudden turn for the worse had very labored breathing and died. This happened about 36 hours after she had been taken off the ventilator. The family was stunned and was in shock. However, their Doctor reminded them he warned them not to ventilate her due to what he predicted could have a high percentage of occuring.
    So my question is why is the mortality rate so high for the elderly; subsequent to being removed from a ventilator?

      No cpap would not work or be sufficient for ventilation because CPAP deals mostly with oxygenation issues not ventilation. Covid-19 pt usually develop ARDS so it would be hard to use cpap. The pressure from the CPAP machine is not the same as a pressure from the ventilators.
      An advanced BIPAP with backup rate, APRV or SIMV-volume regulated -pressure control on the ventilator would be better options. You cannot have oxygenation without ventilation.

I work in a pediatric vent facility with amazing RT's who try their best to explain settings/modes/ functions to me, but since I have them, I never found it necessary to 'know it all'. Now that I care for a baby at home on mechanical ventilation, although my education/experience has taught me everything that I need to know care for him, I just want to 'know it all' !! You explained mechanical ventilation in such a way that, now, my RT's smile in amazement when we converse ;-) thank you so much!

    AC might be called Pt Initiated. Compliance is the inverse, or complement, of inflation Resistance(ie due to fibrosis, obesity, or fluid collection). The various alarms(vol, rate, pressure, pCO2-out, pO2-out, etc.) should always be set, & tailored for near normal respiration, in case the patient's respiratory performance changes for the worse.

    From what I understand.. Ventilators themselves are quite easy to build, it's the operation of said ventilator that is complicated, there has been mechanical hand powered ventilators since the early 1900s. An engineering student made a 3d printable open source ventilator that can be easily mass produced. The issue is creating code and a device that can figure out a patient's correct natural breath cadence and then being able to tell the ventilator to match it and maintain it.. and then of course a monitor to display said data.. What I don't get is why they aren't mass producing hand powered ventilators like that 3d printable one.. that way at minimum instead of someone going on ZERO ventilators and dying, they can at least hand pump them or use some servos and basic coding to make it pump in and out at the average pace.
    . I could make one of those in my garage in 24 hours.

    Hi doctor, my country Indonesia has shortage of hospital beds for COVID-19 like anywhere in the world. Do you think I should stock up oxygen tank for home treatment? At least that is the best thing one can do? Do you have materials on how to operate oxygen tank at home?

    Surely a CPAP home machine can be used in certain instances when a hospital-grade ventilator is not needed. Nasa engineers can design a a dapter for a CPAP to endotracheal tube ETT. They did save the Appolo 13 astronauts with a makeshift filter put together from duct tape and a few other materials in the lunar module in the early seventies.

      Home CPAP machines create only pressure, no tidal volumes. In order to "ventilate" someone you need tidal volume as pressure only helps oxygenation.

      CPAP machine doesn't have ventilator settings on it. Someone on a home CPAP machine is able to breathe on their own. An intubated patient may or may not initiate breaths themselves.

      Dyson have designed their own ventilator for the UK and they are being made.

    Love this lecture. Very clear and it really corrects my wrong perception about ventilation mode. Keep it up!

      There are a few factors in sleep apnea treatment. One place I discovered which succeeds in merging these is the Stans Slumber Method (google it if you're interested) without a doubt the most useful resource that I've seen.Check out all the amazing info .
