The normal ranges for a person's vital signs vary with age, weight, sex, and overall health. These measurements are taken to help assess the general physical health of a person, give clues to possible diseases, and show progress toward recovery. Vital signs (also known as vitals) are a group of the four to six most crucial medical signs that indicate the status of the body's vital (life-sustaining) functions. The same classifications were made using the simplified BP charts and the sensitivity and specificity for the simplified chart in identifying children with prehypertension or hypertension calculated.An anesthetic machine with integrated systems for monitoring of several vital parameters, including blood pressure and heart rateĪssess the general physical health of a person Using criteria from the Fourth Report as the gold standard, each participant’s SBP and DBP were classified as normal, prehypertension, or hypertension. The utility of the simplified BP charts was assessed using data on participants in the school-based BP screening program at the University of Texas Houston during 20 SBP, DBP, height, age, and gender were collected on each child. The chart provides differently shaded areas denoting hypotension, normal BP, prehypertension, stage 1 hypertension, and stage 2 hypertension based on criteria in the Fourth Report. Thus, with the chart, blood pressures are plotted against height to obtain BP percentiles. 1 These values were used in conjunction with data from the 2000 CDC stature-for-age charts to develop various percentile lines for systolic BP (SBP) and diastolic BP (DBP) based on height alone in boys and girls 3 to 20 years old. In the report, 476 separate BP threshold values for various age, gender, and height groups are presented. To construct the BP charts, the researchers used threshold values from the 2004 Fourth Report on pediatric hypertension. Researchers from the University of Texas McGovern Medical School at Houston/Children’s Memorial Hermann Hospital conducted a study to develop and validate a simplified blood pressure (BP) percentile graph, resembling a growth chart, based on height and gender.
