Monitoring blood pressure at home can be a useful tool to keep close watch on blood pressure. Patients taking medications for hypertension may be required to monitor their blood pressure at home to evaluate the effectiveness of the medications at different times of the day. Other patients who experience "white coat hypertension," or an increase in blood pressure when measured in the doctor's office, can establish a record of blood pressure readings at home, possibly ruling out a diagnosis of high blood pressure. Several types of equipment can measure blood pressure at home.
Aneroid Monitors
An aneroid blood pressure monitor is a manual system that includes a cuff with attached stethoscope, inflation bulb and a gauge to read results. The user places the cuff on his arm and pumps the bulb inflate the cuff to 160, or as directed by a doctor. By listening through the attached stethoscope, the patient can read his blood pressure by noting the numbers on the gauge as the cuff deflates. The patient determines the top number, or systolic reading, when he first hears his heartbeat through the stethoscope. The patient determines the bottom number, or diastolic reading, when he last hears his heartbeat through the stethoscope. The American Academy of Family Physicians notes that this type of monitoring device may not be appropriate for individuals who have difficulty hearing.
Digital Monitors
Digital blood pressure monitors are self-contained machines with a cuff attached to a battery-operated or plug-in unit. Digital monitors are available online, as well as in many drugstores. They provide a user-friendly method to check blood pressure, even several times a day. Users simply have to insert their arm into the cuff, which typically comes with a D-ring to help put it on properly. Once the patient turns on the machine, it's as simple as pressing the start button to obtain a blood pressure reading. The American Heart Association suggests that patients check the readings on digital monitors against those in a doctor's office to ensure accuracy.
Finger and Wrist Monitors
Finger and wrist monitors are available for patients with a very large arm circumference, or those who can't have their blood pressure taken in their upper arm, the Mayo Clinic says. When using this type of monitor, the patient should relax the wrist or finger. Patients should check these monitors for accuracy at a doctor's office. The American Academy of Family Physicians notes they sometimes provide inaccurate readings.
