The Vitals Journal in Looms stores every reading you log and plots them on a trend chart so you can see the direction of change over time. A single blood pressure reading tells you where you are today; a three-month trend tells you whether the lifestyle changes or medication are working.
Opening the trend chart
- Go to Vitals Journal
- Select the vital sign you want to review (Blood Pressure, Blood Glucose, Weight, Heart Rate, etc.)
- The chart shows all readings for that vital over the selected time period
- Use the time range selector to switch between 7 days, 30 days, 3 months or all time
Reading the chart
- Each dot represents one reading — tap it to see the exact value, date and time
- The shaded band shows the normal reference range for that vital
- Readings outside the band are shown in amber (borderline) or red (significantly out of range)
- A moving average line (where shown) smooths out day-to-day variation to reveal the trend
- For blood pressure, systolic and diastolic are plotted as separate lines on the same chart
Interpreting what you see
Trends matter more than individual readings. A blood pressure that dips below the range once is unlikely to be significant; a blood pressure that has drifted upward consistently over three months is a conversation to have with your doctor.
Highly variable readings — large swings up and down within days — can also be meaningful. This pattern in blood pressure, for example, may be more relevant than the average level. Lab result trends work the same way — see understanding lab trend charts for how the same principle applies to your blood tests.
