EKG Machines - Soma Technology, Inc.

 

The trace/waveform on an EKG machine has become synonymous with the iconography of healthcare. Many companies use this pattern to identify an association with medical care; you can even find it in our Soma logo! Cartoons and television shows use a flat line to show that someone has passed. However, reading these machines, and the doctors and nurses who use them, have a slightly more complicated role to play in health care.

An EKG is an electrocardiogram. The National Heart, Lung, and Blood Institute describes EKGs for use in diagnosing heart blockage. Each time the heart pumps, it sends an electro signal. The EKG machine records how often one of these electro-signals is sent. “In a healthy adult heart at rest, the SA node sends an electrical signal to begin a new heartbeat 60-100 times a minute.” After the signal is spread across the ventricles, it is recorded as a P wave. Once the signal passes through the AV node, this is the beginning of the Q wave. This is a noninvasive process. There are typically 12 leads that are put on to the body that result in the electrical signals being graphed on the screen.

An EKG would be used on anyone who is at risk of having cardiac issues. These issues include First, Second, Third Degree Heart Block, Mobitz Type I, and Type II. People who are hooked on to an EKG machine are being monitored for significant changes in their heart function.

Settings Used In

An EKG is used in any setting where the heart needs to be monitored. This includes Emergency Rooms, Intensive Care Units, Operating Rooms, and surgical centers. EKGs are almost exclusively never used alone; always in conjunction with other machines, including patient monitors.

 

Ailments

Accord to AKW Medical, an EKG Machine is generally used on people with a heart murmur, arrhythmia (irregular heart beat), myocardial infarctions (heart attacks), and for seizures.

Refurbishment Process

Soma Technology is a leader in refurbished capital medical equipment. We just celebrated 25 years in business and looks forward to excelling in the medical refurbishment market. Not only foes Soma Technology technically refurbish their products, they also cosmetically refurbish them as well. Each product is fully tested and brought back to their OEM standards through; disassembly, inspection, cleaning, repair, replacements of necessary parts, calibration, and special cosmetic restoration. These products are able to function as if they did the day they left the manufacturer. Soma has a team of specified biomedical engineers to work on each equipment before it leaves our facility, ensuring every product functions and looks the way the OEM intended.

Not only does Soma Technology refurbish and offer service on infusion and syringe pumps, Soma also offers these services on a wide range of medical equipment from top manufacturers like GE, Philips, Drager, Physio-Control and more! If you have any questions or just looking for a quick quote on any product give us a call at 1-800-438-7662 where you can talk to a knowledgeable sales representative.

Why choose refurbished? Cost is the biggest deterrent to buying refurbished. Buying refurbished capital medical equipment allows the buyer to acquire about two refurbished devices at the cost of one new one. This helps smaller hospitals with their budget, and help compete with larger hospitals. There is a big difference between used and refurbished equipment. Used equipment implies that the equipment comes as is from the previous owner. Used equipment has an assumed connotation of being mishandled, broken, and/or does not properly function.

Refurbished equipment is far different and much better. The devices are brought to our state of the art facility. Our team of biomedical engineer’s test and calibrate the equipment to be brought back to OEM specifications. Parts that need to be replaced are replaced, thanks to Soma’s large inventory of parts, which can be found at www.SomaMedicalParts.com. After these devices are fixed, they are enhanced cosmetically. The equipment is sanded, painted, and outfitted with new stickers and decals. Finally, the refurbishment process is complete when packaged up and ready to ship.

 

Service Your EKG Machines

Our service team is certified to fix capital medical equipment. Our team of engineers are available with preventative maintenance, warranties, and lifetime phone support.

Contact Your Sales Rep

We have a valued team of sales representatives who are more than willing to assist any needs. We have a wide selection of other capital medical equipment including Imaging, NICU, Ventilators, Infusion Pumps, Patient Monitors, Anesthesia, Surgical Tables, and far more new and refurbished medical equipment. Please remember to contact Soma Technology , if you have questions about any of the pieces of equipment in this article or on our website.

Sell To Us

While Soma is mostly known as a refurbisher of equipment, we also have our purchasing department actively looking to buy equipment to then go through our refurbishing process. First you can submit a request to sell your equipment. A representative will contact you within 24 business hours. Then you will confirm your agreement with your representative. This process is HIPAA compliant.
