In vital signs charting, the symbol used for blood pressure is represented by the caret or circumflex accent (^) symbol. This symbol has become a conventional way to denote blood pressure readings, differentiating them from other vital signs like temperature, heart rate, or respiratory rate. Blood pressure is generally recorded as two values, systolic and diastolic, typically in millimeters of mercury (mmHg), for example, 120/80 mmHg. The caret symbol effectively serves as an indicator that blood pressure values are being reported, allowing for a clear and organized presentation of vital signs on medical charts.

The other symbols listed do not have a specific connection to vital signs in medical charting and are not used as standardized indicators for blood pressure. Each of those symbols may represent various things in different contexts, but only the caret symbol is associated with blood pressure in this specific medical documentation format.
