Non-invasive blood pressure

Nihon Kohden's unique new blood pressure measurement algorithm that reduces the burden on patients and responds to medical professionals' desire for faster results.

 

Measurement of blood pressure with a cuff wound around the arm is familiar from health checks and home use, but blood pressure measurement using the same principles in a clinical setting is an important parameter for understanding the patient condition.

 

In order to measure blood pressure continuously at regular intervals during procedures such as dyalisis or surgery, or in an intensive care unit, the cuff has to be strongly tightened several times and this is very painful for the patient. Sometimes tightening the cuff is even the cause of subcutaneous bleeding, which causes the skin to become red and swollen.

 

Nihon Kohden's engineers thought of ways to reduce the pain for these patients and worked hard to develop a new measurement format that improved the patient experience. After overcoming many obstacles and difficulties, the result was the new iNIBP blood pressure measurement algorithm.

 

iNIBP measures blood pressure using a "linear inflation method" which detects the pulse while inflating the cuff at slower rate than conventional measurement formats. In order to reduce the burden on the patient and respond to medical professionals' desire for faster results, we successfully developed a method of measuring blood pressure faster and with a lower inflation pressure compared to the conventional deflation method.  Use of the new iNIBP blood pressure measurement algorithm, which reduces the pain and discomfort for the patients and allows results to be obtained faster, has spread from Japanese clinical practice to medical practices around the world.

Together with developing the measurement algorithm, we also developed an original cuff for wrapping around the patient's arm (YAWARA cuff).
