Cryotherapy is Cool

Cryotherapy is a real facet of medical treatment that uses extremely low temperatures to help with pain and inflammation. Not to be confused with cryopreservation, in cryotherapy the patients are only subjected to the cold for minutes. It seems like something futuristic, but it is actually an increasingly common treatment among athletes to replace ice baths and ice pack therapies.

More specifically, cryogenic chamber therapy, or Whole Body Cryotherapy (WBC), uses liquid nitrogen to cool a chamber to around -185oF. The patient spends a few minutes in the chamber wearing only a bathing suit, socks, gloves and facial protection (to prevent frostbite), allowing the skin temperature to drop while the core body temperature remains stable. This WBC treatment improves many types of muscle and joint pain and helps in the rehabilitation of injuries.

These cryotherapy systems are currently being used by sports teams such as the San Antonio Spurs, the LA Clippers, and the Minnesota Timberwolves, just to name a few. Everyone from Olympians, to rugby players, to non-athletes looking for pain relief utilize WBC. The super cooling power of liquid nitrogen can be a blessing to those in pain, but precautions need to be taken to assure this tricky chemical remains safe. In the event of a liquid nitrogen leak, the patient could suffocate from lack of breathable air. This is why an Oxygen Deficiency Monitor is important to have in any facility that uses liquid nitrogen.

PureAire Monitoring Systems provides a product that would be ideal for this type of application. Their Oxygen Deficiency Monitor that uses a sample draw system is one of the best in the industry, and can be hooked into an alarm or horn and strobe to alert the chamber operator and patients in case of a leak. The oxygen monitor can even be programmed to turn off the nitrogen tanks in the event of a leak in the system.

The O2 monitor would be situated outside the chamber. Through a tube, air samples from inside the chamber would be analyzed to make sure the oxygen level remains at a safe and breathable 20.9%. Any nitrogen leak would reduce the percent of oxygen and trigger an alarm. Because the oxygen deficiency monitor’s sensor lasts at least 10 years without maintenance, safety is guaranteed for many years to come. Cryogenic chamber therapy has the potential to help many people treat their pain, and with the use of an oxygen monitor, they can do so safely.

Is your company using Nitrogen or other Cryogenic gases? Why PureAire Recommends an O2 Deficiency Monitor for Safety.

PureAire Monitoring Systems, Inc. focuses solely on safety in the workplace, and in laboratory environments. Oxygen deficiency monitors are used in areas using Nitrogen, Helium, Argon, and Carbon Dioxide. PureAire strongly recommends an oxygen deficiency monitor to be installed anywhere cryogenic gases are being stored. The purpose of an oxygen monitor is to alert employees in the immediate area if there is a spill of nitrogen with audible alarm. The use of an O2 monitor creates a safer environment for employees and can alert local fire panels in a building as well. In New York, NY any area using more than 50 gallons of nitrogen the law states, it is mandatory for an oxygen monitor to be installed. The largest problem with these specialty gases are, if a spill occurs there is no noticeable scent or effects. A nitrogen spill can create an oxygen deficient environment rapidly within seconds. For the time it takes the body to realize there is zero breathable oxygen, it is too late. A person will pass out from oxygen deprivation immediately. This is one of the most preventable incidents; simply install an oxygen deficiency monitor for safety. Consider an argument for medicine. If one was to travel to the Amazon in South America, where malaria is common, being unaccustomed to the jungle, wouldn’t it be wise to take malaria pills? What if you have a family history of diabetes? As a family member you may consider taking any necessary precautions to possibly eliminate the concern of diabetes. Maybe by being more physically active, or having a healthier diet, this may delay or stop the onset of diabetes. An oxygen monitor is also similar to a Fire detector in your home or office. You never expect to have a fire, but a fire detector is installed for safety as a precaution. PureAire feels the oxygen monitor is the preventative medicine. Scientists and researchers will always continue to use nitrogen for their experiments. Doctors will continue to use helium to cool the large magnets used for images in the MRI scanner. Carbon dioxide will still be used for all beverage dispensing systems at fast food chains. The one factor people cannot eliminate is the use of cryogenic gases used in everyday life. The only known safety, and scientifically proven device is the oxygen deficiency monitor. The rooms dimensions, a size of the cylinders, the quantity of the cylinders, the types of cryogenic gas being used, whether the gas is being piped into a room, and height of the ceiling all play a role on where, and how many monitors are required. PureAire often gets the question, where do we place the oxygen monitor? How many O2 monitors should we use? A few simple tips can help save a life. Helium is lighter than air, so it is recommended to mount the monitor closer to the ceiling, whereas nitrogen/argon is heavier than air, so mounting the monitor closer to the ground would make sense. Carbon dioxide is also heavier than air settling to the ground. PureAire manufactures oxygen deficiency monitors for many different areas. In all cases PureAire use an oxygen deficiency monitor using a 10+ year sensor. PureAire can be contacted at 1-888-788-8050, http://www.MonitorOxygen.com, and http://www.PureAireMonitoring.com.

PureAire Makes Oxygen Monitor for Nitrogen Generators

Nitrogen generators are most commonly used in areas where on-demand nitrogen is preferred rather than, storing liquid nitrogen (LN2) in cylinders. Nitrogen generators have a lower cost of operation, and can be used where smaller amounts of nitrogen are needed. Nitrogen generators are used in the pharmaceutical industry, testing laboratories, cryogenic facilities, welding manufactures, and petrochemical environments.

The question often comes up from a safety standpoint, is nitrogen a safe? The answer is usually no. An Oxygen Monitor is needed where LN2 or nitrogen generators are stored. Nitrogen makes up roughly 70% of the air we breathe, though oxygen is only 20.9%. Oxygen is a precious gas that we take for granted. Ultra pure 99.9% nitrogen is unsafe in confined spaces, and nitrogen generators are usually stored in these types of areas. PureAire has developed an Oxygen Monitor with a 10+ year sensor made specifically for nitrogen storage areas, and nitrogen generators.

PureAire’s O2 Monitor uses a called Zirconium Oxide sensor. Most Oxygen Monitors use a disposable electrochemical sensor that typically only has a life expectancy of 12-18 months along with other complications. Some examples of problems with the electrochemical sensors are: drifts to thunderstorms, or barometric pressure changes, humidity changes, and temperature fluctuations.

PureAire has pioneered the way using a zirconium oxide oxygen sensor. The technology used is far more advanced than the “Old style,” electrochemical sensors. The sensor used is based on ions being passed through the sensor, and at 20.9% oxygen a certain quantity of ions cross the sensor. Thus, giving a current to the monitor giving an accurate reading between 0-25%. If the oxygen concentration has been lowered, fewer ions cross the sensor hence, lowering the reading on their display. Intuitively, if there is higher known concentration of oxygen, so will the sensors readings on the PureAire Oxygen monitor.

The crucial understanding of the sensor is what gives PureAire’s clients the 10+ life expectancy and accuracy. Another great property of the ZrO2 sensor is NO CALIBRATION is required. The sensors ion technology limits the need to calibrate. PureAire’s Oxygen monitor does not have problems with barometric pressure, temperature, or humidity changes. PureAire’s O2 Monitors are completely stable (-40c to 50c) in all environments.

Nitrogen generators create high pressure in the cylinder after the gas has been created. This can be dangerous especially, overnight while employees are not in the proximity. PureAire also has a feature called latching. If there is a leak overnight, the alarm can stay alerted until the client turns off the switch in the morning.

PureAire is also looking for distributors to help distribute their oxygen monitors. In the past year PureAire has grown 50% and is continuing to gain more recognition. The demand for the O2 monitors has been more abundant exponentially. The PureAire ion based technology O2 monitor should be the only monitors being sold for 0-25% due to the lack of maintenance and calibration.

PureAire Receives CE Approval on its Oxygen Monitor with 10+ Year Sensor.

PureAire Monitoring systems, the proud manufacture of their oxygen monitor has received a CE approval. The recent CE approval is monumental for PureAire selling to European countries. PureAire has been selling their O2 monitors in the USA for over 11 years. With a larger demand from their clients it was certain a CE approval would be beneficial to their product line, especially in Europe. PureAire’s oxygen monitor is highly revered for its 10+ year sensor requiring no replacement sensors, calibration, or maintenance.

When PureAire’s VP of Sales, Brandon Alan was asked, why is your O2 monitor different? Brandon explained the background of oxygen monitors; he discusses there is a lengthy maintenance process required to have a properly functioning monitor, until we, PureAire came out with the Aircheck Oxygen Monitor.

Brandon States, “About 95% of all Oxygen Monitor manufacturers use a continuous depleting sensor for O2 their readings. Clients will replace sensors on average from 12-18 months at $250 per sensor, and requires quarterly calibrations if their lucky. We have overcome the burden for our clients, and have provided an O2 monitor that is ultimately hassle free by using the zirconium oxide sensor. Gaining recognition of PureAire’s oxygen monitors has been an uphill battle, but companies are catching on quickly.”

So, where might you find Oxygen monitors being used?

Brandon: “Oxygen monitors are used in areas where the client may be worried for their safety due to a potential low oxygen level. More recently MRI rooms have been a risk due to the helium storage in the large magnet MRI scanners. Most people are not aware of the risks associated with helium. Most people joke if there was a leak of helium, they would talk like Mickey Mouse. Though, I do find humor in high talking Walt Disney characters, this can be a very serious matter. Our typical oxygen monitor client uses liquid nitrogen cylinders, nitrogen dewars combined with confined spaces, and laboratories containing cryogenics. The three largest Cryogenic gases (Oxygen depleting gases) are Nitrogen (N2), Argon (Ar), Helium (He), and Carbon dioxide (CO2).”

How do you see the CE approval helping your oxygen monitors sales?

Brandon: “I anticipate once the message gets out that we have a CE approval, European companies will start to take notice of our monitors. We understand in order to sell our products to other European countries we must have an approval. I am hoping companies will use our oxygen monitors based on our technology. Were hoping the old throw away sensor technology becomes an idea of the past in Europe, and our O2 monitor with 10+ year sensor becomes the product for the future.”

Increased Demand for PureAire’s Oxygen Monitor for Nitrogen and Helium Storage

When storing or using Liquid Nitrogen, Helium, CO2, or Argon cylinders in a confined space, what are the potential risks? Gas leaks are the most common, requiring the need for an oxygen deficiency monitor for protecting employees in the workplace. With inert cryogenic gases, loose or broken fittings can leak gas into a room displacing oxygen, causing impaired judgment or loss of life to workers. PureAire, one of the leading suppliers of Oxygen Deficiency Monitors uses a non-depleting zirconium oxide sensor that has a 10+ year sensor life and requires no calibration or periodic maintenance.

“Cryogenics are mostly stored in confined spaces such as, offices, freezers, or hallways. One of the most overlooked additions to having LN2, He, Ar, or CO2 cylinders ranging from 25-250lbs is the O2 monitor. MSDS sheets all have a variation of information mentioning, high pressure and suffocation with No Odor1.” “In high concentrations, asphyxiation occurs with no warning. Symptoms may include loss of mobility/consciousness and must apply artificial respiration if breathing stopped2.”

The rapid release of nitrogen, and other various cryogenics possess absolutely zero signs of immediate danger. NIOSH, and OSHA states anything under 19.5% oxygen is considered hazardous, and a dangerous environment for employees. The earth is a wonderful source of calibrated oxygen and we breath 20.9% Oxygen. PureAire’s Oxygen detector is one of the most widely used real time monitors for detecting leaks among cryogenic gas cylinders in storage rooms. If a gas spill or leak occurs, PureAire’s Oxygen monitor is designed to turn on strobes and audible alarms to warn workers to evacuate the location. It also has built-in relays that can active ventilation fans to bring in fresh air.

PureAire’s Oxygen monitor uses a 10+ year zirconium sensor. The monitor requires zero maintenance, and calibration because of its non-depleting long life sensor. Built in “supervised watchdog” software continuously monitors all instrument functions 24-7. PureAire’s Oxygen monitor is not affected by humidity, temperature, or changes in barometric pressure. Rapidly changing barometric pressure changes from thunderstorms will not disrupt PureAire’s Oxygen Deficiency Monitor. The majority of oxygen deficiency monitors sold use depleting electrochemical sensors that need complete replacement frequently. PureAire’s Oxygen monitor can save up to $400 annually in replaceable sensors.

Oxygen (O2) Monitors: Disposable Sensors eating your Cash? PureAire Introduces 10 + Year Sensor.

PureAire Monitoring Systems is a leading manufacturer in the gas monitoring industry. When it comes to O2 deficiency monitors PureAire makes the most reliable, longest lasting, and affordable oxygen monitors.

It has been an international standard for the past three decades to use oxygen monitors with disposable sensor cells, (electrochemical sensors). All disposable sensors require frequent maintenance, monthly and quarterly calibration (false alarm if not calibrated), and usually drift to changes in barometric pressure. At PureAire, we made a point to fix this familiar problem and offer you a solution. We created a better product, one that eliminates the inconveniences of disposable sensors while continuing to meet your needs.

The 10+ Year O2 Deficiency Monitor is a unique product offered by PureAire. The Zirconium Oxide (ZrO2) sensor is the key technology that has allowed us to continue providing reliable and long lasting monitors over the years.

The ZrO2 sensor does not rely on partial pressure, or need a reference gas like disposable sensors. Also, our sensor does not require electrolyte, a depleting source of power, while disposable sensors require this fluid to give the sensor its power. Our sensor’s power comes from 24VDC, and does not have a depleting source. PureAire’s 10+ Year 02 Deficiency Monitor is much more reliable, requires no maintenance, and does not need to be calibrated. There zirconium sensor does not have the biases associated with the disposable sensor technology. This means no more false alarms and drifting, and an always-accurate reading.

With over 1,000 monitors in the field, PureAire continues to gain support amongst its users with a hassle free O2 monitor for safety. With our O2 Monitor you can be assured if there is a leak from any cryogenic gas (LN2, He, Ar, and CO2), our built-in audible will go off without any false alarms.
