1. What is Mean Excluding First per NHS?

Definition: This calculator computes the average blood pressure according to NHS guidelines by excluding the first reading.

Purpose: It helps healthcare professionals and patients accurately assess blood pressure by following standardized NHS protocols.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Readings — Blood pressure measurements in mmHg (systolic/diastolic)
• First reading — Always excluded per NHS protocol
• Average — Mean of remaining valid readings

Explanation: The calculator processes multiple blood pressure readings, skips the first one, and averages the rest to provide a more accurate representation.

3. Importance of NHS Blood Pressure Calculation

Details: Excluding the first reading accounts for potential "white coat hypertension" and provides a more reliable baseline measurement.

4. Using the Calculator

Tips: Enter all blood pressure readings (one per line) in systolic/diastolic format (e.g., 120/80). The calculator will automatically exclude the first reading.

5. Frequently Asked Questions (FAQ)

Q1: Why does NHS exclude the first reading?
A: The first reading is often higher due to anxiety or unfamiliarity with the clinical environment.

Q2: How many readings should I provide?
A: NHS typically recommends at least 3 readings, with the first being excluded.

Q3: What format should the readings be in?
A: Enter as systolic/diastolic (e.g., 120/80), one reading per line.

Q4: Does this calculator validate the readings?
A: Yes, it only processes properly formatted readings (numbers separated by /).

Q5: What if I only have two readings?
A: The calculator will use just the second reading (excluding the first).
