patient ventilator asynchrony is a term that describes a mismatch of the timing and gas
delivery between a patient and the mechanical ventilator we created this video to cover the
medical definition and provide a brief overview of the topic so if you're ready let's get into it
as previously mentioned patient ventilator asynchrony is characterized by inappropriate
timing of a delivered breath between a patient and the mechanical ventilator this increases
work of breathing and makes it more difficult for the patient to breathe comfortably on the machine
in this case due to intubation the patient is unable to communicate which makes it
challenging for respiratory therapists and medical professionals ventilator dyssynchrony is a similar
term used to describe this interaction and can generally be used interchangeably with patient
ventilator asynchrony patient ventilator asynchrony can result in a number of
adverse effects including the following patient discomfort increased work of breathing respiratory
distress increased anxiety over distension ventilator induced lung injury prolonged
sedation prolonged duration of mechanical ventilation and increased time in the icu each
adverse effect caused by ventilator asynchrony is associated with an increased mortality rate
some examples of the common causes of patient ventilator asynchrony include the following
ineffective triggering incorrect ventilator mode incorrect ventilator settings
inappropriate triggering flow desynchrony exhalation to synchrony auto peep artificial
airway problems drug induced problems and certain lung diseases asynchrony can occur due to several
other causes as well these are just a few of the most common examples the management of patient
ventilator asynchrony depends on the specific costs since inappropriate ventilator settings
are typically involved making proper adjustments appears to be the best treatment method for
example the practitioner may need to adjust the flow sensitivity or inspiratory time a different
ventilator mode may be considered as well patient ventilator asynchrony can occur in both assisted
and controlled ventilatory breaths with that said in general the less control the ventilator
has on the patient's respiratory pattern the less likely they will experience asynchrony
volume controlled ventilation typically results in more cases of the synchrony because it controls
volume flow and time on the other hand modes such as pressure support ventilation typically result
in the least amount of the synchrony cases proportional assist ventilation and neurally
adjusted ventilatory assist are two ventilator modes that are effective in avoiding the synchrony
that is because they allow the patient to select the ventilatory pattern that is delivered
but again for this video we just wanted to provide you with a brief overview
of the stopping we'll be breaking it down into much more detail in a separate video
real quick if you don't mind do me a huge favor and hit the like button it really helps support
the channel and i greatly greatly appreciate it and you might as well go ahead and subscribe for

a better understanding of this topic if so be sure to let us know down in the comment section below
and if you want to dive even deeper we do have a full guide on our website
i will drop a link to it right below this video down in the description thank you so
much for watching all the way to the end have a blessed day and as always these my friends
