0:00now it's important to discuss and
0:02understand the means of transmission and
0:05once we understand the means of
0:06transmission it's a lot easier to
0:08prevent the spread of bacteria or
0:12microorganisms so means of transmission
0:14we have several ways we have Airborne we
0:17have droplet we have bloodborne
0:20foodborne fecal or oral mucous membranes
0:24Vector direct contact as well as
0:28indirect contact
0:30with Airborne Airborne is just that
0:33these are microorganisms that can travel
0:34large distances they're very light their
0:37transmission is a lot easier because it
0:40is so light and has the ability to
0:42spread and it can spread quite rapidly
0:45for droplets droplets only carry about
0:48three to six feet they're heavier in
0:51their transmission and so droplets they
0:53do spread but they're not going to
0:55spread as easy as an Airborne pathogen
0:58would
0:59bloodborne is just that it's going to be
1:01transmitted through blood foodborne is
1:04going to be transmitted through food
1:06fecal and oral same thing mucous
1:09membranes our eyes our ears our nose our
1:13mouth all our direct mucous membranes
1:15and all can be a means of transmission
1:19as well as vector and the term Vector
1:21there Vector born is referring to a tick
1:24a dog a mosquito also transmission can
1:27be direct contact which is just that
1:29think of sexual contact uh contact with
1:32an infected person's skin which can be
1:34prevented by using our personal
1:36protective equipment
1:38and then we have indirect contact
1:40otherwise known as fomatisse and
1:43fomatisse is going to be indirect
1:45objects that we touch think door knobs
1:48elevator buttons stairwells those sorts
1:51of things that are indirect also can be
1:53a means of transmission now here we have
1:56the cycle of infection and we've talked
1:58about this before but the cycle of
2:00infection has to have its progress it
2:03has to progress through the cycle in
2:06order to make it to what's called a
2:07susceptible host and so it starts with
2:10the reservoir house and our Reservoir
2:12host is the gentleman at the top there
2:14who was clearly not feeling his best
2:16self uh as the reservoir host he is now
2:19carrying the pathogens uh and he is
2:22looking for a means of exit the means of
2:25exit is going to be this unprotected
2:27cough or sneeze that has occurred
2:29and unfortunately this unprotected cough
2:32or sneeze has happened on someone's
2:34glass that is uncovered
2:36that glass now becomes the means of
2:38transmission
2:40and it is waiting for a means of
2:42entrance here it's using a mucous
2:45membrane which is the mouth she drinks
2:47out of the glass
2:48and this cycle continues now she is a
2:51susceptible host the cycle just
2:53continues to make its way around until
2:55we break that cycle using preventative
2:58measures
2:59and breaking the cycle we have the
3:02ability to use medical asepsis now
3:05medical asepsis understand is not a
3:08sterile environment medical asepsis is
3:11clean we know that a and the word
3:13asepsis means absent or without so this
3:17is absent or without pathogens but it is
3:20not all pathogens not all microorganisms
3:23uh it is a strict housekeeping standard
3:26that we need to adhere to and it is it
3:29is oversought by government guidelines
3:32also breaking the cycle most important
3:35what we learned a few weeks ago was hand
3:37hygiene we can stop the cycle of
3:40infection by washing our hands proper
3:43hygiene is the most important aseptic
3:45procedure that can break the cycle of
3:47infection and we now know how to wash
3:50our hands using medical asepsis let's
3:54discuss where Ham washing is necessary
3:56so of course we know that when we're
3:59washing our hands especially with
4:00medical aseptic technique we're using
4:03soap and water when do we wash our hands
4:06well we wash at the start of our shift
4:08we always wash before and after eating
4:11we would wash before and after using the
4:13restroom before and after smoking and
4:17when your hands are visibly soiled
4:19now we also learned the technique if
4:22after medical aseps is hand washing we
4:25can also use disinfectant and so hand
4:28asepsis with alcohol-based hand
4:30disinfectant has to be a minimum of 60
4:33percent alcohol content in order for it
4:36to be deemed effective
