Improved Dialysis Safetyall about redsense blood loss detection


Redsense cares about your safety

A serious threat to your safety during dialysis 

Did you know that dialysis patients are exposed to a potentially life-threatening incident during hemodialysis treatment?1

If not, you are not alone.

During hemodialysis treatment, a dislodged needle can result in severe blood loss. Even though it can occur as often as 1 in 720 treatments, many patients are not aware of this serious complication called Venous Needle Dislodgement (VND).2, 3

More importantly, what most are unaware, the pressure monitor within dialysis machines are notoriously unreliable and cannot successfully trigger and alarm when a needle dislodges.4


The Redsense alarm system can help youredsense dialysis02

To improve patient safety, Redsense Medical has developed a monitoring system that can detect the very first sign of a blood leak using patented fiber optic technology. An alarm is triggered when the sensor comes into contact with blood so one can address the issue immediately and stop the blood flow.

Redsense also follows IEC Public Available Standard (PAS) 63023; if the dialysis machine does as well, these devices can connect and communicate and the blood flow will be stopped automatically when blood is detected.

Redsense is easy to use and offers both a venous fistula and central catheter solution. The system is CE marked and FDA cleared for sales in the USA, and available for all dialysis providers.


Cleveland Clinics case study

Cleveland Clinic provides both inpatient and outpatient hemodialysis for high-acuity patients with a higher than average risk for Venous Needle Dislodgement (VND). In February 2010 a quality improvement project was introduced to reduce VND rates. In the prior 3 months, internal data review showed 3 undetected VND episodes (2 class IV hemorrhages), incidence of 1 VND per 538 HD treatments.

The project introduced Redsense blood detection device alongside the standard policies and procedures for cleaning, disinfecting, and securing the venous access wound and the venous needles. Zero undetected VND episodes were recorded between February 15 and December 30 2010. The overall occurrence dropped from 13 in 2009 to 4 in 2010, incidence of 1 VND per 1750 HD treatments. Redsense helped in achieving a relative risk reduction of 70% in the Cleveland Clinic.6


Feel safe, be safe

Let Redsense keep an eye on your access. In more than 10 years of clinical use, patients and nurses have felt safer when using the Redsense alarm system to detect VND.

The US department of Veteran affairs even mandates the use of Redsense.7

Redsense can enable you to safely perform your hemodialysis treatment from the comfort of your own home.

If possible, ask the nursing staff at your clinic for Redsense during your next treatment or medical checkup.
