Respiratory Therapy - Modes of Mechanical Ventilation - AC vs SIMV

In this video I break down the basic settings for Assist Control Mandatory Ventilation (AC) and Synchronized Intermittent Mandatory Ventilation (SIMV), as well as the difference between SIMV and AC. Hope you watch, enjoy and learn something.

[@RespiratoryCoach]

Thanks Gordon!! Glad it made sense!!! Keep up the strong work!!

Thank you so much... I watched your videos all day and they are just so awesome. I now understand ventilator better. Its so much better than reading textbook!

I tell you what man, I have been an RT for almost 10 years now, and still find great value in your videos. Great stuff! -Army RT

[@RespiratoryCoach]

Thank you, Army RT!!! Glad to see a veteran on here brushing up on things!!! You're awesome!!

[@choetsongawang6873]

I heard that SIMV is most uncomfortable compared to AC, that's your thinking of that? Thanks.

[@jocelynizweird27]

Thank you for all your helpful videos!

You are so welcome! Thank you for the support!!!

[@user-vf4ds5sy3j]

Thank you for your excellent lecture, very helpful.As a pediatrician, we rarely adopt the AC mode, since babies tend to be tachypnea, AC mode may cause big problems. AC mode allows patients to trigger a gas delivery at any time and give them a full assistance: fixed iT, fixed VT...which may cause total iT longer than eT leading to gas trapping even pneumothorax. SIMV mode does good, however, it can also make a conscious patient very uncomfortable, patient can trigger the ventilator, the ventilator can trigger patient’s spontaneous breathing either, that’s Hering reflex, once it happens, the patients will be struggling

[@RespiratoryCoach]

Thank you for this insight. I appreciate the contribution. As always, thank you for watching!!!

Oh man, I wish my professor would watch your videos to see how to properly make these complex subjects understandable. Most of us leave his classes more confused than when we walked in. If you are at the one private allied health school in manhattan, I know you know what i mean, lol

[@AndrewWOOT]

Thank you for the clear explanations! Our class was thrown similar waveforms like these, but it was very hard to follow along. The way you explained it made so much more sense. Along with your past videos, the repetition on your explanations help a ton!

[@RespiratoryCoach]

Glad it was helpful, Andrew. Thank you for watching and kindly commenting!!!

[@AndrewWOOT]

Respiratory Coach And i was wondering if I can recommend a future video. Would you be able to make a video on selecting the right mode to put the patient in? Specifically CMV, AC, and SIMV. Also patient scenarios you give are really helpful as well! Thank you again!

[@omarvierapulido2299]

Very good this video, I am taking advantage of each video today to clarify concepts. I want to see all of them little by little since now I am in the Mechanical Ventilation subject. Thanks again !!!

U have very well explained both the modes , thank you so much I request make any video for PC -BiPAP mode

[@RespiratoryCoach]

Thank you, Dr. Prajapati. Essentially, when in NIV-PC the set I time is active on all breaths. During NIV S/T mode, the patient controls the I time during spontaneous breathing, and the set I time is only active on mandatory breaths.

[@shmilyx007]

I finally understand the difference between AC and SIMV after watching this video, even though I read a couple books on ventilators! Thank you sooooooo much! I was always confused what would happen if patient triggers a spon breath when the machine is about to deliver a breath. Still one question: if patient Just triggers a breath before machine breath, for AC you get set assisted volume on top of patients own breath voume, which is why it causes breath stacking, But for SIMV, it synchronize with patient own breath, then how much tidal volume patent gets eventually?cos I notice for SIMV, for example we set up TV at 500ml, if patient happens to breath Just before machine breath, they eventually get more than 500ml, it is not around 500ml, sometimes it could be 600ml quite a big difference, it makes me wonder that might be a risk of breath stacking As well, But my educator says SIMV Does not cause breath stacking.

[@futurerustic]

In AC mode, wouldn't the machine take over the breath initiated by the patient, thus avoiding the issue of stacking?

[@ebtehalali1311]

Thank you sooo much for the greatest clarification ever!! Here is my question.. why there is some people out there claiming that SIMV is the worst mode you could use?

[@RespiratoryCoach]

I'm really not sure. Some think that SIMV taxes the patient's respiratory muscles during a time when full mechanical ventilation is appropriate. I think it's more of a balancing act on a per patient basis that should be considered. Even ARDSNet protocol doesn't specify a mode, so I'm really not sure. You're very welcome and I thank you for watching and commenting!!!

[@Archie.499]

Yeah I do like simv mode but ppl really hate simv and consider it to be outdated.

[@indian7211]

Your great.. Plz explain about volume control and pressure control

[@jakubd3426]

Great video. What if patient intiates breath after mandatory breath has started in SIMV?

[@geodoc76]

Excellent lecture !

[@maria13201]

thank you so much for the explanation, but i have a question what would happen if the patient's spontaneous breathing's exhalation aligns with the mandatory breathing's inspiration? does it allow the patient to exhale fully?

[@reannaEncore1]

Hi, thank you so much for your videos, they are super helpful in bettering my understanding of ventilation modes! I have a question, what is the difference between IMV and SIMV?

[@RespiratoryCoach]

Hello, Reanna! IMV allows for spontaneous breathing between mandatory breaths, but does not synchronize with spontaneous breaths. This may lead to breath stacking. SIMV does synchronize. If the patient initiates a breath close to a time triggered mandatory breath then the vent will synchronize the mandatory breath with the patient's spontaneous efforts with the intentions of avoiding breath stacking. Hope this helps. Thank you for watching and commenting with your question.

[@zeeshanzeeshan32]

If a patient is put on VC-AC with set R/R of 10 /min n patient triggers breath after every 3 seconds n assissted breaths got delivered so my query is will the ventilator be delivering the preset manadatory breaths at all during the whole minute .

[@Suzi_P]

Always love your videos. Would you please talk about INO by any chances? Thank you

[@RespiratoryCoach]

Hi Suzi! I have this video that touches on INO. Let me know if you have further questions. kzbin.info/www/bejne/ooekhYyGf9-Bn6M Thank you for watching and commenting with your question!!!

[@georgetabex8094]

wow,thankyou so much.

[@KYoung2]

Hello quick question, at 26:34 under the pressure waveform, if the patient initiates a breath at 3 seconds would the ventilator synchronize at that time too? or is it right before the set RR at 7seconds?

[@javadaghrab5687]

CAn you go over mechanical ventilation in cases like DKA 'severe metaboluc acidosis with huge minute ventilation. These pt's may have 40 litters of minute ventilation ventilation. Lets say guy is 80 kg Can i put him on SIMV MODE IF SO WHAT KIND OF SETTING.

[@abrahamgutierrez7400]

Hi good morning. Is SIMV ventilation mode any good for patiants whit problems of apneas during there sleeping and eating times?

[@RespiratoryCoach]

No, because it allows for a minimum rate and minute ventilation to be maintained.

[@markthorne2156]

Great job!

Thanks Mark! Appreciate you watching!!

[@tubeysr]

Please say in which scenario/pathology SIMV is typically used, and in which scenario simv should not be used. TIA.

[@RespiratoryCoach]

HI and thanks for commenting with your question. Everyone wants to know which mode to use for which pathology. Modes of ventilation are not specific to pathologies. The answer is which mode is best for this patient, with this pathology, at this time!

[@deliachindris9183]

CPAP/PSV With backup mode is considered SIMV ?

[@farhanqadeer82]

How do you find out if patient is flow hungry on ACVC - How the wave form will look like.

[@RespiratoryCoach]

Hello. In AC-VC, you set volume and flow, therefore the only thing that will vary is your pressure. You want to watch for a dip in your pressure waveform. Your pressure volume loop will also have an S appearance. Hope this helps!!

why patients in AC mode hyperventilates?

[@graceanne8698]

can shifting to SIMV with pressure support help?

[@RespiratoryCoach]

In theory yes! SIMV will allow the patient to generate their desired tidal volume instead of being controlled by the vent.
