The present invention proposes a technique to prevent erroneous readings in non-invasive blood pressure (NIBP) monitoring. According to the proposed technique an NIBP monitor is reset after each measurement event. . The NIBP monitor may be rest using a reset button provided on user interface (UI) of the NIBP monitor. Alternatively, the NIBP monitor may be automatically reset to normal blood pressure (120/80 mm of Hg) on sensing deflated state of a cuff of the NIBP monitor.
The present invention relates generally to non-invasive blood pressure (NIBP) monitoring technique and more particularly to a technique for preventing erroneous readings in NIBP monitoring.
Generally, in an emergency ward, all patients that come in are not admitted and after almost every couple of parameter checks on a particular monitoring unit, a patient being checked changes. Such fast turnaround of patients in the emergency ward presents challenges in maintaining accuracy in readings of the monitoring units, such as a non-invasive blood pressuring monitoring unit.
Non-invasive blood pressure monitoring methods are simpler and quicker than invasive measurements, require less expertise, have virtually no complications and therefore are amenable to use in the emergency wards. However, their use in emergency wards presents some challenges.
Typically, in a manual or an auto NIBP measurement, a cuff is inflated to a pressure value higher than a previously measured systolic pressure corresponding to a previous patient. There are two scenarios commonly observed in an emergency ward. In a first scenario, for example a first patient in the emergency ward records a systolic pressure of 220 mm of Hg. The monitoring unit considers a pressure of 220 mm of Hg as desired pressure value for a subsequent reading. A second patient comes to the emergency ward with a lower blood pressure (BP), for example blood pressure of 120 mm of Hg. The monitoring unit still pumps up to a pressure value of more than 220 mm of Hg. As a result, the second patient faces discomfort as well as a high measurement of blood pressure is erroneously displayed.
In a second scenario of the emergency ward a prior patient records a systolic pressure of 120 mm of Hg. Now, the monitoring unit considers 120 mm of Hg the desired pressure for the subsequent reading. A subsequent patient who come to the emergency ward with a blood pressure higher than the prior patient, for example a blood pressure of 180 mm of Hg, the monitoring unit pumps two or more times in order to reach the higher value of 180 mm of Hg. Again the subsequent patient suffers discomfort as well as incorrect measurements are displayed.
It would be desirable to have a technique for efficient use of NIBP monitors.
