Implications of Noninvasive Blood Pressure Pumps on Mean Arterial Pressure

Noninvasive blood pressure pumps are recommended as the primary form of acquiring patient blood pressure to test for blood poisoning. The Philips IntelliVue Patient Monitor MP5, the Philips SureSigns VS4/VS3 Vital Signs Monitor, the Philips EarlyVue VS30 Vital Signs Monitor, the Philips IntelliVue Patent Monitor MP2/X2, the Philips IntelliVue Patent Monitor MMS, and the Philips IntelliVue Patent Monitor MP3/X3 were tested for accuracy. The control condition for hypotension was 95/55 (68) mmHg, normal blood pressure was 120/80 (93) mmHg, and hypertension was 155/85 (108) mmHg. The order of values is arrayed according to diastolic, systolic, and mean arterial pressure. The results displayed no observable difference between error or uncertainty. The average relative uncertainty values were identical for calibrated and uncalibrated devices. These values included 0.32%, 0.38%, and 0.51% for hypotension, normal blood pressure, and hypertension respectively. This result is significantly smaller than the blood pressure values. Also, devices with the greatest deviation in variance were the Philips IntelliVue Patient Monitor MP5 and X2, which exhibited the maximum standard deviation in seven out of the nine cases. The device with the smallest deviation in variance was the Philips IntelliVue Patient Monitor VS3/4 with a minimum variance of zero. Further experimentation is encouraged to collect a larger sample size to complete hypothesis testing and compare it to the industrial quality control of Philips.
