Basically, you set a target volume. The patient should be spontaneously breathing. When they do, the vent will adjust the pressure support in the background to guarantee that target volume. if the patient can only pull in 300ml, the vent will push extra support to get to the target 500ml.
Exactly and the extra pressure support will stop at the high pressure setting. The v60 will alarm at that point and let you know it can't hit the guaranteed volume.
@@rtclinic do u have to have an exhalation leak on these if using as a closed system with a trach? I see ur supposed to if using for NIV. I ask cause I left a patient on all night with it closed using it on their trach with cuff inflated. I ran an ABG in AM and CO2 was great when I realized it’s probably supposed to be open.
how do you determine your expiratory time on the avaps. Do you just calculate your tct? I just find it out there is no I:E ratio displayed compared to other Philip NIV machines
Exp time will be somewhat variable based upon the patient. That is one of the best attributes of AVAPS, it moves with the patients needs. But to get the actual Exp time you'll need to subtract the Itime from the TCT. You are on the right track!
Hello! Thank you for this helpful info! If I may ask, so if the patient is tachypneic, how does it affect the augmentation of the tidal volume given that you have a set rate. I hope it makes sense what I'm trying to ask. It just confuses me how we set a rate when the patient has to be spontaneously breathing on this mode. Thank you and I look forward to hearing from you
The rate should be used only as a warning that the patient is breathing slowly. The v60 will alarm if the patient is breathing exactly with the set rate. It is alot different that a set rate on invasive ventilation.
When you initiate AVAPS is it ok to just keep turning up your min and max P until you reach your your target Vt, and then just back min P back off? It seems to take a long time for the machine to reach target Vt sometimes. Also, when do you think AVAPS is the better mode to use vs S/T? Thanks
Mike, That is a great option to transition from S/T to AVAPS. I think AVAPS is much better to manage transient hypoventilation related to obesity or advanced lung disease, especially during sleep/naps. AVAPS is also good for those anxious patients that have difficulty tolerating BiPAP. S/T is best to manage acute respiratory acidosis! Great question!!
@RajanKumar-m2s5u the pressure from the machine will assist in deeper breaths. Since it is "volume targetted" the pressure will increase if the tidal volumes start decreasing.
Say the goal of tidal volume set by the machine is 380 like you illustrated. What does it mean when pt's tidal volume to be way higher, say 800, and the alarm is going off? How to trouble shoot that? Thank you!
@@rtclinic Or Jimmie, It sounds to me like you are using AVAPS on a patient with an acute VQ mismatch (or BiPAP on metabolic acidosis) . This is dangerous. Especially if the patient is already fatigued. Air hungry patient + AVAPS = intubation
Thanks for the video! Quick question, the "average" in AVAPS is an average of how many past breaths? Since you say it takes time to adjust it must be an average of quite a number of breaths I'm guessing, no?
I am a 55 year old male that was diagnosed with COP D and asthma from 911. I am recently getting more attacks that are more related to COP D and get me in the ER where I'm very close to be intubated. Now there is a multiple of problems one the area where I live is extremely dry and windy in Texas Lubbock. 2 the problem is allergies and a very high. All these things are playing a role in ticketing to me and getting my lungs to over Excite is site or Exacerbate The situation massivelyIn your opinion what would be the best machine for me and can I use oxygen with this type of machine. Right now my pulse ox Is ranging around around 87 or 83 it doesn't stay there once a month oxygen but it is a problem. I hope you get this message very soon to help me decide. My Pulmonologist It's extremely hard to get to and not very friendly. Any help will do or advice thank you Is my name is bill
Bill, You definitely need home oxygen and likely a bipap when you rest (depending upon your co2 levels). I would try to get into your primary care physician and try to get an order for an overnight oximetry study.
@@rtclinic believe it or not it's not the doctor but the insurance company that's pushing back insurance company says my CO2 levels are perfectly fine. I wish somebody would explain that to the doctors that saved my life on April 7th and being admitted to the hospital the next 11 days being on a BiPAP machine. also on have a medical bill that's over $175,000 for 11 days. I guess I made that up to according to the insurance company. I was always told insurance companies your great when you're in that glass wall, but when it comes time for you to break that wall to get help from that insurance company Nobody's around. that's okay my life expectancy now that I know what it is it's roughly six months according to my pulmonologist. if I get another severe attack at home I know what I'm going to do and it's going to be less than $0.55 to do it. thank you for your commentary.
@@rtclinic Thanks for replying. I asked because my brother who is in ICU with anoxic brain injury and recurring pneumonias was put on this machine with cuff down, which led to aspiration pneumonia. I was told by the treating pulmonologist that in this machine he could only have the cuff down/deflated because the trigger alarms are not the same as in the ventilator. the next week another Pulmonologist came and said to put "cuff up" because of aspiration risk. Unfortunately the RT's that I asked the question were not helpful 😕
@N Q Good. There are a couple of technical pieces to the equation. Most noninvasive circuits are vented, in this case the cuff will need to be inflated. If it is a non-vented circuit the cuff will be deflated. The RT should know the difference. This would explain why the pulmo MD might give different answers because they didn't know what type of circuit is being used.
They're just a lil slow it's like acvc with pressure regulation. (PRVC). The residents didn't understand. I saw them put 30 orders in trying to put the order in correctly.

how about invasive ? for intubated patient ( chronic Vent)
When you initiate AVAPS is it ok to just keep turning up your min and max P until you reach your your target Vt, and then just back min P back off? It seems to take a long time for the machine to reach target Vt sometimes. Also, when do you think AVAPS is the better mode to use vs S/T? Thanks

S/T is best to manage acute respiratory acidosis!
Great question!!
@RajanKumar-m2s5u the pressure from the machine will assist in deeper breaths. Since it is "volume targetted" the pressure will increase if the tidal volumes start decreasing.
@RajanKumar-m2s5u I would say it is always better, but in the non acute case, it is more comfortable and efficient
@RajanKumar-m2s5u It augments the strength of your respiratory muscles.
Say the goal of tidal volume set by the machine is 380 like you illustrated. What does it mean when pt's tidal volume to be way higher, say 800, and the alarm is going off? How to trouble shoot that?
Thank you!
It sounds like you need to lower the minimum IPAP.
@@rtclinic Thank you!

This is dangerous.
Especially if the patient is already fatigued.

I want to ask you something.. if patient breathless in deep sleep than which mode helps to breath him?? And than what setting need to be change??
More than likely the CPAP or EPAP needs to be increased.
@rtclinic i think its central sleep apnea.. where brain stop sending signal to respiratory muscle.. that is i'm asking to you
Thanks for the video! Quick question, the "average" in AVAPS is an average of how many past breaths? Since you say it takes time to adjust it must be an average of quite a number of breaths I'm guessing, no?
I dont want to guess. Let me look it up and I'll let you know.
It takes the average Vt over one minute and adjusts the IPAP every minute to try to reach the desired Vt
Augmenting with 2,5 cm per minute
Thanks so much!!!
can we use AVAPS in NIV mode?
Yes

hello, cn this be used on someone with a tracheostomy and a deflated cuff?
Nope. It would need a sealed airway to measure the correct amount of tidal volume.

Are they attaching the circuit to the trach or are they using a mask with a capped trach?

Sir plz plz guide me , if we set Respiratory rate 10 and patient spontaneous breathing rate is 15 so we will get RR 25 or 15 in monitoring parameters
The total rate will be 15. The set rate is just a backup. 10 breaths will make sure a breath is taken every 6 seconds
@@rtclinic Thanks a lot sir
I’m not sure why but RTs I work with can understand Volume Ventilation with an intubated patient but cannot understanding AVAPS… 😂
I usually find that once the physicians figure it out, they'll order it on everyone😁
@@rtclinic I put a kid on AVAPS in ER, it was like looking at dogs listening to a dog whistle
They're just a lil slow it's like acvc with pressure regulation. (PRVC). The residents didn't understand. I saw them put 30 orders in trying to put the order in correctly.
thank you so much for your videos
