Mechanical Ventilation - Auto PEEP, Breath Stacking, Air Trapping [Explained Clearly]

In this video we dive into the topic of AutoPEEP, also known as breath stacking or air trapping or intrinsic PEEP as related to mechanical ventilation. Better understand these complex but important concepts!
Introduction: 0:00 - 2:25
Mechanism of Auto PEEP: 2:26 - 9:30
Causes of Auto PEEP: 9:31 - 14:08
Complications of Auto PEEP: 9:32 - 21:17
Diagnosis, Management, and Scalars - 21:18 - 37:57
Auto PEEP occurs when a patient on mechanical ventilation does not have enough time to fully expire their tidal volume before the ventilator gives another breath. This leads to a small amount of tidal volume being retained in the lungs with each breath and over time this builds up creating Auto PEEP. The breaths are "stacking" on top of each out or the air is being "trapped" in the lungs creating intrinsic PEEP! (see what I did there?)
Auto PEEP can occur for a number of reasons. The most common include a high minute ventilation. If you are administering huge tidal volumes or if you have set the respiratory rate quite high, sometimes a patient will not have enough time to fully expire each breath. Lung compliance contributes and more commonly when a patient has high airway resistance, such as with COPD or asthma.
Auto PEEP can cause hypotension as the intrathoracic pressures increases decreasing venous return. It also can cause ventilator induced lung injury, patient ventilator dyssynchrony, and increased dead space ventilation.
It is most formally diagnosed with an expiratory hold maneuver, but you can look at the pressure, flow, and volume scalars to assist in diagnosis. It also tends to cause a high plateau pressure. Manage it by treating the underlying illness, increasing the amount of a time a patient has to expire, and if it gets severe disconnecting the patient from the ventilator.
All of this explained and more!

    11:46 Did you misspeak here when you said prolonged *expiratory* times cause breath-stacking or am I missing something? Nonetheless, fantastic video with plenty good info! Sincerely, a Respiratory Therapist that is trying to brush up on Intrinsic PEEP again 😄

    Couple of questions. First, 30 breaths per minutes seems way too much, wouldn't this keep the patient in an extreme state of physical tension. Seems to me longer slower deeper breathing would stimulate healing much better. Such fast breathing would likely increase risk of lung injury and hypertension, would it not? Healthy, calm people don't breathe once every two seconds. 5 to 6 breaths a minute creates far more calm and healing. Slower breathing allows for breathing deeper into the alveoli, while rapid breathing tends to be shallow, with less gas exchange. Second, if this is such a problem, why hasn't someone invented a ventilation device that monitors the air volume in and out and has the ability to help gently draw out any remaining unexhaled air volume prior to the next ventilation input? Seems to me, with modern technology, this should be possible.

    Great questions! 30 breaths per minute certainly isn't "physiologic" meaning that we don't set the respiratory rate on the ventilator that high unless the patient is so incredibly sick they may die without it. There are some complex reasons that a higher respiratory rate may be indicated for these super super sick patients, mostly though to help them breath off their carbon dioxide to help make the blood less acidic. In the setting of AutoPEEP though, higher respiratory rates actually have the opposite affect! I think that there is a ton of opportunity for technological improvements in this space. I am no engineer so it is outside my area of expertise, but I can't fault you for wondering why we don't have alternate approaches to these problems that extend beyond using a ventilator.
