Session notes
What should a useful device session log record?
Record settings, fit, duration, and visible behavior without turning observations into medical claims.
Before the session
Prepare the controller, sleeve, cable, and treatment area.
During use
Stay awake, seated, and within the stated product scope.
After the session
Check comfort and follow the care instructions.
A session log is useful when another person can understand what happened without guessing. It should capture equipment facts and direct observations. It should not pretend that a setting, sensation, or timing note proves a treatment outcome.
Record the session context
Write the date, time, activity before use, seated position, clothing, and reason for making the note. If the session followed travel, exercise, or long sitting, record that context without calling it a cause.
Record the equipment state
Include the selected mode, pressure label, heat or vibration status, planned duration, battery state, and connection condition. The complete ST-504 guide can help locate product terms, but exact values and limits come from the current manual.
Record what was observable
Note sleeve movement, chamber order, display behavior, tubing position, and any localized sensation. Use concrete language: “the upper chamber released later than expected” or “the sleeve edge folded.” Avoid conclusions such as “the device repaired circulation.”
Record what changed next
If the session stopped, write why. If the fit was corrected, say what changed. If a symptom appeared or increased, stop and use the appropriate medical or support channel. Do not restart just to make the log complete.
Source boundary for session logs
A log supports communication; it does not diagnose, clear, or prescribe. Keep the manual, manufacturer support, and professional guidance as the controlling sources for their respective questions. FDA medical-device information can add general context but cannot interpret the record for an individual.
Use the same time format each day. Note whether the session ended normally. If the controller stopped early, write the visible message or physical event. This is useful equipment information, even when no health conclusion can be made.
Keep the record short enough to use
A useful log does not need a long narrative. Use one line for the equipment state and one line for the person’s observation. For example, record the charge state, selected controls, session length, fit, and any visible behavior. Then record whether the session was comfortable, stopped early, or produced a change that required attention. Avoid copying a conclusion from a product description into the log. The value of the record is that another person can see what happened and what changed. If a safety question appears, preserve the original wording and seek the right support instead of editing the note into a reassuring summary.
