Medical Gas Backfeed

Medical air is one of the most crucial medical gases serving an NFPA 99 Category 1 facility or space. It is typically responsible for keeping ventilators and blenders running and downtime of any length is simply not acceptable.


When work must be performed on the air compressor source, especially within the control panel, power may have to be disrupted to safely complete that job. One way that EMGS helps ensure that the medical air supply remains uninterrupted is to provide a back feed manifold setup located just downstream of the medical air dryers but upstream of the source valve (or at an auxiliary valve, if available, immediately downstream of the source valve).

The back feed manifold is a fairly simple setup while still allowing for change out of one cylinder at a time. The manifold can be extended to more cylinders if the facility flow is very high, or the duration of shutdown is long enough to require it.

Feel free to contact us if you have any questions about medical air or any other medical gas or vacuum temporary setups. We offer rental manifolds, rental medical vacuum systems and rental medical air systems to help with your next shutdown.

Rebuilding Amico & Beacon Medaes Outlets (Series B style, Diamond style quick connect)

When you have a hospital of any age it is likely that you probably have outlets manufactured by more than one company. When this happens you may get outlet repair parts mixed up especially in the case of Amico and Beacon (Series B) style outlets. If you’ve ever rebuilt the latch valve of one of these outlets and noticed that you fixed the leak but created a flow problem (low or no flow) the reason is because of the dust cap used by Amico and Beacon Medaes.

At first glance they appear to be identical, but upon further inspection you will notice subtle differences in each one. Amico has two different styles that come in their standard repair kit, a white cap and a gray cap. The gray cap can be put aside because we are talking specifically about Ohmeda/Medaes Diamond style quick connect outlets. The gray dust cap is specifically for Chemetron (Allied Healthcare) style vacuum inlets.

In the picture below you will note a couple of key differences. The front of the Beacon Medaes dust cap has three lines that meet in the middle to form a triangle. The Amico dust cap is flat with no texture. If you look at the back you will notice another key difference and this is what can cause flow issues. The Amico has a raised portion on the inside front of the dust cap, but the raised portion is solid. The Beacon Medaes dust cap also has a raised portion but it is hollow and has a hole in the middle, this allows the brass poppet to seat slight further within the barrel than on the Amico latch valve. That is why mixing the dust caps can cause no flow issues when Amico dust caps are used on Beacon Medaes outlets.

The moral of the story is be sure to keep your outlet parts segregated and use the appropriate manufacturer repair parts for each individual outlet or inlet.





Risk Assessment Services

When patients and doctors are dependent upon medical gas equipment for
their safety, nothing becomes more important than ensuring said equipment is
functioning perfectly.

EMGS, Inc. offers risk assessment services and consulting to your hospital
personnel. We can carefully craft a user-friendly report to provide to your staff
displaying the potential hazards and failures of the equipment they are in charge
of maintaining. This report will document the common causes of equipment issues,
and the control measures that can be put in place to prevent these issues. We will
also show who is typically responsible for ensuring these measures are attended to.

This report will prove invaluable to your staff. Let EMGS, Inc. help put you on the
path to superior safety and performance so the doctors and nurses can rest easy in
providing care to their patients.

Surgical Vacuum Line Cleaning Services

One of the most common complaints from surgeons in operating rooms is, “There is not enough suction present.” Most of the time this isn’t the fault of the central vacuum system itself, but rather the failure to maintain the suction canisters and the lines associated with them. When canisters are not emptied in a timely manner, the vacuum lines can become occluded with debris.

EMGS, Inc. offers vacuum line cleaning services for this problem. Please contact us today for more information. 770-459-5920.

Medical Gas Master Alarms – Problems and Solutions

Medical gas master alarms are among the most crucial pieces of equipment in a healthcare facility.  They monitor life saving gases such as oxygen, nitrous oxide, medical air, etc.  The Joint Commission and other regulatory agencies have moved the master alarm system for medical gases to the top of their list when addressing areas of concern.  In other words, if you have a problem with your medical gas master alarms, you need to fix it quickly.  Problems or deficiencies with these alarms present a distinct hazard to patient safety and must be dealt with.

The issue within most facilities is that the alarm systems, or at least the wiring is very old.  So while other portions of the system have been upgraded, the master alarms are still operating on an antiquated copper wire system that may not meet the current specifications for the newer alarm panels.  The other issue is that hospital ceilings are full, very full, with little room to run additional conduit and wire, making the addition of alarm panels in different locations costly and time consuming.

There is another way…ethernet.  Your hospital has it, every hospital has it, most houses even have it!  Ethernet is a scalable technology that is likely kept up to date by your IT department.  At EMGS, we have the expertise to work with your IT department and utilize your existing infrastructure to provide you with a master alarm anywhere you have a computer with an intranet connection to your facility’s network.  This is all accomplished via the Amico AIMS Ethernet solution.

EMGS recently completed this project at Houston Medical Center in Warner Robins, Ga.  They had a need for a master alarm in their engineering annex building, but running new wire all the way to that building was going to be difficult due to the crowded ceilings and having to traverse buildings.  We implemented the Amico AIMS Ethernet solution, and now they have a touchscreen panel (pictured to the right) that shows them in real time the status of all of their master alarms for the facility.  They also get an e-mail notification any time an alarm goes off, thereby creating a log of alarms and notifying the appropriate staff.

If you have medical gas master alarm issues, take heart, they aren’t as bad as they seem.  They can be resolved and it can be done with less of a headache than you think.  Give us a call and we will work with you to create a solution that is perfect for your facility.
