Scientists at the University of Minnesota have created a blood vessel replacement that is composed of biological materials but does not have living cells at implantation. Rather, the replacement becomes repopulated with cells by the recipient’s own cells once implanted. This ground-breaking creation could benefit not only dialysis patients, but also those with coronary issues.…Details
Meet the New pHoenix XL
Our most advanced dialysate meter to date,the pHoenix XL digital dialysate meter is a convenient, hand-held, syringe-style meter for quick and accurate measurement of conductivity, temperature and pH. All without the hassle of annual calibration.
Introducing Our New Combination Solution
We have combined two of your most valuable NIST-traceable standard solutions into one bottle: 14.0 mS/cm and 7.00 pH in one solution! Make your daily calibration in half the time so you can focus on what matters most: patient care.
Better performance, more accurate results
Make sure you’re getting the best performance from your digital dialysate meter. Let Mesa’s expert technicians restore your meter to its original optimal working condition.
While healthcare remains a point of contention in America’s current political climate, some good news came from bipartisan efforts. On September 26, the Senate passed the CHRONIC (Creating High-Quality Results and Outcomes Necessary to Improve Chronic) Care Act of 2017. This bill amends title XVIII (Medicare) of the Social Security Act.1 In layman’s terms, the…Details
As more and more states legalize marijuana for medicinal and recreational use it is important to determine its effects on kidney function in healthy young adults. A select few have performed studies to determine if there is any correlation between marijuana use and kidney function. One study, published in the Clinical Journal of the American…Details
Mesa Labs has engineered the pHoenix XL digital dialysate meter to accommodate a measurement module that can be replaced in the field. This not only reduces the cost of ownership, but also eliminates the need to send your meter in for service. The measurement module is conveniently available for order and purchase in our online…Details
50 mS solution now available
Mesa’s new 50 mS Conductivity Standard Solution allows the user to verify accurate readings during final bicarbonate testing using a NIST traceable standard as a qualified data point of 50 mS during meter verification and calibration.
Dialysis is based on the diffusion and ultrafiltration of fluid across a semi-permeable membrane. As blood flows past one side of a semi-permeable membrane, dialysate flows by the other side. Fluid and smaller solutes and pass through the membrane, but larger substances (e.g. large proteins and red blood cells,) are blocked by the membrane, mimicking the filtering process that takes place in the kidneys.
Hemodialysis works by removing waste and water from circulating blood by filtering it outside the body through a dialyzer which contains a semi-permeable membrane. Blood and dialysate flow in opposite directions, contributing to the concentration gradient that allows the maximum amount of urea and creatinine to be removed from the blood.
Dialysis solutions contain similar levels of certain minerals (e.g. calcium, potassium) as healthy blood. The blood of dialysis patients contains higher levels of potassium and urea than the dialysate so constant replacement of the dialysate through the dialysis process maintains this imbalance ensures that undesired solutes are removed from the patient’s blood. For bicarbonate, the level is set slightly higher than healthy blood to encourage diffusion. Individual patient needs dictate the concentrations of the components of dialysate, typically prescribed by a nephrologist.
To ensure patient safety, Mesa offers several digital dialysate meters to help the nephrology technician verify that the dialysis machine is functioning properly. The pHoenix, HYDRA and NEO-STAT test various parameters utilizing Mesa’s easy to use syringe style concept which is small in size and offers a host of advantages including a large, digital display, one-touch calibration and an auto-off battery saving feature.
In addition to these syringe style digital dialysate meters, Mesa offers its 90XL technician meter which can be used to test and calibrate all types of delivery systems and water purification systems.
Mesa Labs maintains a sophisticated calibration lab for all of its instrument products, including its line of digital dialysate meters.
Mesa’s in-house calibration is far more extensive than the user calibration options available to our customers. Mesa’s dialysate meters, in general, have two sets of calibration coefficients. A set that is exposed to the customer/user and is used to make minor adjustments to the accuracy of the device and a set that is exposed, in general, only to Mesa’s in-house calibration software.
Also, Mesa’s Calibration lab has the N.I.S.T. traceable standards at the facility to calibrate the meters to. A typical user doesn’t have access to N.I.S.T. traceable standards.
Lastly, if there is an issue with the function of the meter, Mesa has the OEM parts to correctly service, repair and re-certify a customer’s meter. Should an instrument or meter need repair, it can only be accomplished at our factory.
