Hey coach could you make a video of Weaning or improving pt w/ trachs. Method for speaking valve, capping. I'm new rt only about 2 years experience and 1 year was icu hospital work which I felt like a slave passing nebs and charting vents. I now work at long term facility which is better one on one w/ pts ..vented and non vented. I just want to help these pts the best I can. Thank you so much for all ur videos .

@greensahuaro2834 2 жыл бұрын

Many thanks for this awesome informative video! So! Would it be pk to initially set a pt on an approximate Vt, low peep and on volume ventilation, then get a plateau pressure, then calculate driving pressure then ventilate according to driving pressure? So I would use the formula you mentioned: vt/Cstat. and monitor that driving pressure as a trend to see pt's progress? Also having in mind pt's lung condition getting better or worse? What's a normal driving pressure?

@greensahuaro2834 Жыл бұрын

looks like increasing peep with higher plateau improves mortality because it opens alveoli more therefore improving ventilation of gases across the lung alveolar membrane. I guess that's why PRV helps stiff lungs. It keeps the alveoli open to improve gas exchange, which is the main function of the lungs! Hum?!

Can you explain to us how to calculate or to know our Optimal peep?

@tonylugo3033 4 ай бұрын

How do you know when you have the correct peep and Vt for to avoid lung injuries?

@greensahuaro2834 Жыл бұрын

So! depending on lung condition; and if the lungs are stiff as in ARDS, we can change driving pressure by increasing Peep; for better ventilations, get that Driving Pressure and Static Cl numbers and calculate Vt? But! I think only getting the numbers on Volume ventilation and applying it on Volume or Pressure and when ventilating keep an eye on the Plateau Pressure trend to watch for improvement and deterioration?

@greensahuaro2834 2 жыл бұрын

Looks like driving pressure is related to pressure gradient. If so, then a ventilator giving us a pressure gradient can help us ventilate better. I remember using a Drager ventilator which on the first 6 breaths can figure out the pressure gradient to set a proper flow. So, if vents can figure out the pressure gradient and the flow, then we can get the right VT, get a Cstat, and have a Driving Pressure measurement?

@tubeysr Жыл бұрын

Beautifully explained, thank you! So we can reduce the driving pressure by increasing PEEP, and ideally driving pressure should be kept ≤15 cmH20 ?

@RespiratoryCoach Жыл бұрын

Absolutely! When optimized PEEP can improve lung compliance which can decrease driving pressure.

@nedybelizaire7915 2 жыл бұрын

how do we determine driving pressure before placing pt on a vent? We will still need a formula for tidal volume to initiate mechanical ventilation

@samuelhodge2475 2 жыл бұрын

Can you explain why it appears as is some pts can go above the set PIP on pressure control? For example if the total pip is set to be 25 (20+5) I see total pip displays on as 28 on the servo while the pt is triggering breaths on the vent?

@RedBeardShaves Жыл бұрын

Just curious, I have been strictly monitoring Driving pressure for 2 years now and have came up empty handed that it has created any benefit to mortality? Have you had similar findings? I actually found that identifying optimal PEEP and leaving it there with a very gradual wean has proven better outcomes than following driving pressure. I would love any current studies or findings you have that show results either way. Thank you!

Thank you for this education. I have two questions: 1: Which modes of ventilation allow us to measure driving pressure? 2: Can you please show us [maybe in a video] how to measure driving pressure in APRV mode? Thank you in advance.

@fuadfayyah1387 2 жыл бұрын

Hi bro For the first question, a mode of volume controlled is used in order to measure DP .. because the calculation needs a specific set of tidal volume, while you can't do this in pressure control mode because the volume is variable regarding the specific amount of pressure you're delivering. For the second question, as long as APRV is a spontaneous mode of mechanical ventilation, then the volume is variable regarding how much the pt. takes breath in , which will directly affect your DP reading I hope I could answer you, best regards

@Shak-MD 2 жыл бұрын

@@fuadfayyah1387 The problem then becomes: Should we always use VC on ARDS patients? The vast majority of our new crop of ARDS patients [ you know who I'm talking about] do not tolerate VC. And therefore, we cannot guarantee good lung protective ventilation. As such, I opt for APRV for most of our patients.

@fuadfayyah1387 2 жыл бұрын

@@Shak-MD Well I'm also experiencing the same issue with covid ARDS patients .. theoretically if you used pressure control mode it would be more of not damaging the lungs because you're delivering a specific amount of pressure regardless to the volume given, and also it would be more beneficial in getting better oxygnation status because MAP would be increased But then I realized that almost all protocols for ARDS is based of volume setting, such as the ARDSNET and DP protocols .. which needs you to measure Pplat, Cstat .. exc. so you can adjust settings and deliver almost the optimal required setting for such case For APRV, it's really a very good mode for primarily hypoxic patients (type I respiratory failure), which would be beneficial in optimizing the oxygnation status primarily .. specially those patients present with ARDS If I could help with APRV, you should watch the previous video for Respiratory Coach about APRV, it's really clear and understandable learning video in order to correctly understand and adjust your settings By the way, good discussion to have .. cheers mate 👍👍

I have a pratical question since I am a technician. Would it help to reverse mortality to purposely puncture the lungs and place chest tubes on a patient with ARDS where ventilation pressures are high, even while using PRV..pressure release ventilation? using the chest tubes sort-of -like a pressure relief mechanism to prevent barotrauma and blood pressure/heart issues? In order to possibly save a life or to give more options or opportunity for survival?.....and also consider adding surfactant? Hm!? I wonder?!

@greensahuaro2834 Жыл бұрын

So. Does that mean that as soon as we place a pt on a vent we are to find what's the mean airway pressure with static complaince to set the right peep and the right vt?

Wouldn’t driving pressure be= Pplat decided by auto peep + peep? Taking into account the total PEEP. This is seen while using the esophageal balloon monitoring.

But! To decrease Driving P with a stiff lung, we can increase peep to deliver a proper Vt and to decrease Driving pressure! Right? ...according to the bars shown earlier!

As always, great video! But crossing out ibw... thats a long shot I believe.. ibw is such an easy way to initiate a vent, then after I think we can work it to change to the correct driving pressure... so I think only after we initiate with ibw, correct driving pressure will be superior. Lolol

What is the formula to obtain the appropriate tidal volume from the known data?

@RespiratoryCoach 2 жыл бұрын

Hi Olivia.....Vt = Driving Pressure X Cstat. Once you know your static compliance you can multiply by your desired driving pressure and that will yield your target tidal volume.
