AMA Blood Pressure Average Calculator

Blood Pressure Average Formula:

\[ \text{Average SBP} = \frac{\Sigma \text{SBP}}{n} \] \[ \text{Average DBP} = \frac{\Sigma \text{DBP}}{n} \]

Number of Readings:

Average SBP (mmHg):

Average DBP (mmHg):

1. What is AMA Blood Pressure Average Calculator?

Definition: This calculator computes the average systolic and diastolic blood pressure readings according to American Medical Association (AMA) guidelines.

Purpose: It helps healthcare professionals and patients determine accurate blood pressure averages from multiple readings for proper diagnosis and monitoring.

2. How Does the Calculator Work?

The calculator uses the formulas:

\[ \text{Average SBP} = \frac{\Sigma \text{SBP}}{n} \] \[ \text{Average DBP} = \frac{\Sigma \text{DBP}}{n} \]

Where:

\( \text{SBP} \) — Systolic blood pressure readings (mmHg)
\( \text{DBP} \) — Diastolic blood pressure readings (mmHg)
\( n \) — Number of readings

Explanation: The calculator sums all SBP and DBP readings separately, then divides each sum by the number of readings to get the averages.

3. Importance of Blood Pressure Averaging

Details: AMA recommends averaging multiple BP readings taken at different times for accurate diagnosis of hypertension, as single readings can be misleading.

4. Using the Calculator

Tips: Enter your SBP and DBP readings as comma-separated values. Ensure you have the same number of readings for both SBP and DBP.

5. Frequently Asked Questions (FAQ)

Q1: How many readings should I enter?
A: AMA recommends at least 2-3 readings taken on separate occasions for accurate averaging.

Q2: What's considered a normal BP average?
A: Normal is <120/80 mmHg. Elevated is 120-129/<80. Stage 1 hypertension is 130-139/80-89. Stage 2 is ≥140/90.

Q3: Should I include all readings or just the high ones?
A: Include all properly taken readings for an accurate average, unless instructed otherwise by your physician.

Q4: How does this differ from home BP monitoring?
A: Home BP averages should be slightly lower (typically <135/85) than clinical readings to account for white coat effect.

Q5: What if my SBP and DBP averages fall in different categories?
A: Your overall classification is based on the higher category of the two averages.
