bp_tracker

Tool to track and evaluate blood pressure recordings.

Overview

bp_tracker is a command-line utility for recording and analyzing blood pressure readings. It stores readings in a simple text file format and provides health classifications based on standard blood pressure ranges.

Usage

usage: bp_tracker.py [-h] [-f FILE] [-a ADD ADD ADD] [-r RANGE [RANGE ...]]

options:
  -h, --help            show this help message and exit
  -f FILE, --file FILE  Report FILE (default bp_numbers.txt)
  -a ADD ADD ADD, --add ADD ADD ADD
                        Add in the order of systolic, diastolic, pulse
  -r RANGE [RANGE ...], --range RANGE [RANGE ...]
                        Begin and end dates are in YYYYMMDD format. Default today
                        for end. For example: 20230809 20230824 or 20230809

Examples

Report all readings:

./bp_tracker.py

Add a new reading (systolic 120, diastolic 80, pulse 60):

./bp_tracker.py -a 120 80 60

Report readings for a specific date range:

./bp_tracker.py -r 20230809 20230824

Report readings from a date to today:

./bp_tracker.py -r 20230809

Use a different data file:

./bp_tracker.py -f /path/to/mydata.txt

Data Format

The data file uses space-separated values with one reading per line:

systolic diastolic pulse timestamp

Example:

# Comments start with #
120 80 60 20220914.1407
130 85 65 20220915.1008

Fields:

• systolic: Systolic blood pressure (integer)
• diastolic: Diastolic blood pressure (integer)
• pulse: Pulse rate (integer)
• timestamp: Date and time in YYYYmmdd.HHMM format (auto-generated when adding)

Lines starting with # are treated as comments. Blank lines are ignored.

Health Classifications

The tool classifies blood pressure readings according to standard medical ranges:

SYSTOLIC:

• 0-49: Low, medication required
• 50-69: Low, at risk
• 70-85: Low
• 86-120: Good
• 121-129: Elevated
• 130-139: High, stage 1
• 140-179: High, stage 2
• 180+: High, crisis

DIASTOLIC:

• 0-45: Low, medication required
• 46-55: Low, at risk
• 56-65: Low
• 66-79: Good
• 80-89: High, stage 1
• 90-119: High, stage 2
• 120+: High, crisis

Report Output

The report shows:

• Latest systolic reading with classification and range
• Latest diastolic reading with classification and range
• Average systolic with classification and range
• Average diastolic with classification and range

Example output:

Systolic 130 (elevated [121-129])
Diastolic 85 (high: stage 1 [80-89])
Systolic Average 125 (elevated [121-129])
Diastolic Average 82 (high: stage 1 [80-89])

Testing

Code Review

A comprehensive code review has been performed on this codebase. See the following documents for details:

• CODE_REVIEW.txt: Detailed analysis of bugs, robustness issues, and improvements
• REVIEW_SUMMARY.txt: Executive summary with prioritized recommendations
• QUICK_REFERENCE.txt: Quick command reference and key points

CRITICAL BUGS IDENTIFIED:

1. Line 297: sys.exit() called with incorrect arguments
2. Lines 317-320: Crash when no results match date range
3. Lines 131-133: Unpacking None causes TypeError

See CODE_REVIEW.txt for complete details and recommended fixes.

Dependencies

REQUIRED: None (uses Python Standard Library only)

OPTIONAL (for development):

• coverage: Test coverage reporting
• black: Code formatting
• flake8: Code linting

Install optional dependencies:

pip install coverage black flake8
