The document discusses monitoring blood pressure with a 7-day recorder. (1) A 7-day recorder can record blood pressure over a full week, allowing doctors to see patterns that a single office visit may miss. This provides a more complete picture of a person's usual blood pressure levels and any changes over time. (2) The recorder collects blood pressure readings throughout each day, including during sleep. This data helps doctors determine if high or low readings happen at specific times of day or in response to certain activities.
