safety indexed connector systems are standardized connections for high and low pressure gas delivery
sources that are used to reduce the risk of administering the wrong gas to the wrong patient
we created this video to cover the medical definition and provide a
brief overview of this topic so if you're ready let's get into it
the distribution and regulation of medical gases is an important but often forgotten topic in
the field of respiratory care in general oxygen delivery systems store medical gases at extremely
high pressures so before a gas can be administered to a patient the pressure must be reduced to a
safe and workable level you should also know that administering the wrong gas to a patient is one
of the biggest risk when it comes to medical gas therapy this is why as a respiratory therapist you
are required to read the cylinder or outlet label first before administering the gas with that said
human error does occur which is why safety index connector systems were created to help prevent
misconnections between respiratory care equipment the three most common examples include a-s-s-s
p-i-s-s and d-i-s-s a-s-s-s stands for the american standard safety system
this system is primarily used for high pressure connections between the large
gas cylinder sizes that range from size f through h and k this applies to their attachments as well
this system uses unique threading and sizes which makes misconnections very difficult
so that the incorrect gas is not delivered to the wrong patient p-i-s-s stands for the pin index
safety system this connection type is actually a part of the american standard safety system
but it is primarily used for the high pressure connections between the smaller gas cylinders from
size e and under the piss system uses a yoke type connection that utilizes different pin positions
for each of the different types of gases the pins and holes must align perfectly in order
to secure a connection for gas delivery this also prevents misconnections so that the incorrect gas
is not delivered to the wrong patient then we have the d-i-s-s system which stands for diameter index
safety system this connection type is different from the ass and piss because it is designed to
prevent misconnections of low pressure gas delivery sources just to give a reminder the
american and pin index safety systems are used for high pressure gas delivery sources the diameter
index safety system is used for low pressure sources the diss is often used at the inlets
of flow meters ventilators and other pneumatic respiratory care equipment is also used at the
outlets of pressure reducing valves that are attached to cylinders and at the station outlets
of central piping systems this system uses unique external threading which also makes misconnections
very difficult so that the incorrect gas is not delivered to the wrong patient
i bet you're starting to recognize a pattern here while each of the three systems are unique
the goal of each is to prevent misconnections in order to avoid an injury that could come
from administering the wrong gas just to give a recap the american standard safety system
is used to provide high pressure connections for large gas cylinders the pin index safety system
is a variation of the ass that uses a yoke and pin for connecting small gas cylinders ranging from
size aa through size e and the diameter index safety system is different from the other two
because it is used to provide connections for low pressure outlets that are less than 200. real
quick guys do me a huge favor and hit the like button it really helps support the channel and
i greatly greatly appreciate it and while you're down there go ahead and click the subscribe button
as well because we have a ton of other videos on our channel that i think you will enjoy
just a reminder this video is for educational and informational purposes only but hopefully
you can take what you learned and apply it to your career as a respiratory therapist
what topics should we cover next let us know down in the comment section below
and if you want to learn even more about this topic we do have a full guide on our website
i'll 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 breathe easy my friend
