thing everyone so i'm very excited just burst into our study
00:00:05
which is about a new not thought of as of agree on
00:00:08
observation to i guess streak feeding tube that has monitoring function
00:00:16
so it is is a pilot study that's took place at the university hospital in boston
00:00:22
and inclusion criteria for preterm infants a bit taken station no h. or post conception no age
00:00:28
of over to to to beat a dead were in need of a gastric feeding tube
00:00:33
in these infants replaced a regular guest checked u. bit a menu to that is
00:00:39
a six french guys to do which is equipped with multiple electric electrodes
00:00:46
the chip was originally developed for the gnarly
00:00:49
adjusted vented atari assist shortly caught now
00:00:54
so on the five days we took measurements over does
00:00:58
to you that was attached to an amplifier
00:01:03
simultaneously week actually reference signal for that we attach
00:01:08
three additional surface electrodes to the inference arses
00:01:11
and c. d.s um electrodes are also attached to the amplifier
00:01:17
also we money toward the standard monitoring data of c. n. n. y. c. you
00:01:24
then we we surely analyst are captured sick notes by the visual and i think we
00:01:31
had a customised software and with this software we chose of every hour of measurement
00:01:37
um three different categories of um of the signals
00:01:41
so we divide it it in um as a faggot signals that pair of very good quality
00:01:47
as of august signals denver of not so good quality and also
00:01:51
to spend that money during that was not of good quality
00:01:57
so moving on to the results we were able to include thirteen preterm infants
00:02:03
with a mean guy station all age of thirty two weeks thirty two weeks
00:02:09
we took a thirty five measurements that lit to
00:02:12
over three hundred segments of these ten minutes
00:02:16
in each category that i was explaining before that means that we
00:02:20
were able to compare over four hundred channels thousands of heartbeats
00:02:29
and this figure you see now um the signals that we captured
00:02:34
we have to testify got sickness eight four eight electrons and the upper part the
00:02:39
most proximal electrode on the on the part the most distant an extra out
00:02:44
then we have our reference signal which was captured by these surface electrons and we
00:02:50
have to standard monitoring data in the lower part also if the numeric sed
00:02:57
um on the first state uh now we see the comparison off
00:03:02
the heart rate extraction we compared the pacific i leads
00:03:07
with the standard money touring or reference verges a surface electrodes so
00:03:12
you see that in d. nice is that okay uh um
00:03:18
uh signals we have a very high sensitivity and also a very high positive predictive value that
00:03:25
means out of one thousand heartbeats we have only three heartbeats that were falsely detect
00:03:32
if we take a look at the park quality segments of the pacific out and also the standard monitoring
00:03:39
we have the decreasing often sensitivity at the positive predictive value which is comparable
00:03:47
now on this figures greasy at the devaluation of
00:03:50
these falsely detected heartbeat so we have here
00:03:55
the time and we have here the amount and we see that indian nicely
00:04:01
uh signals of to justify gas we have very few um falsely detected
00:04:06
um heart beats and the most of them are in between of one sec
00:04:11
second so imagining a child who has a heartbeat of one hundred fifty per minute
00:04:16
this is not prevalent for a capturing sporadic idea or a relevant topic here also we have
00:04:24
um on the uh uh but i'm not so good um the signals
00:04:30
i'm more variations but also in the amount if you have in mind the
00:04:34
disease or over four hundred thousand heartbeats i'm not so much deviations
00:04:42
so in conclusion we could show that it is possible and it is also
00:04:47
safe to extract the heart rate over i guess trick feeding tube
00:04:51
and we could show would at the um results are
00:04:55
comparable to the today's standards monitoring down stuff
00:05:00
so if we look further into the future um we are now and
00:05:05
trying to do the same um extraction with the respiratory rate
00:05:10
l. c. c. on this site we haven't nicely respiratory um
00:05:14
signal in the more distant part of the electrodes
00:05:19
also and we were able to extract swallowing um p. x. still here
00:05:24
you see a paris tells the slave going to justify cost
00:05:27
starting proximal going more the style so we're able to visualise and swallowing next
00:05:34
so if we matching that we would be able to
00:05:37
continuously um one it or uh swallowing briefing coordination
00:05:42
this kind of marie towering that we are looking at it's really interesting
00:05:49
thank you for your
00:05:58
thank you for this very interesting and i'm just a presentation
00:06:02
about a new tune yeah it is there any questions
00:06:11
yes i use a play
00:06:15
need to make sure you two will look at position or is it the same for standard notice you too
00:06:22
should we checked it by looking at the morning tar um according to you uh electrode
00:06:28
changing the are complex is so you can verify it to the eating of the of the two
