Ambulatory blood pressure monitoring is a method of measuring blood pressure at regular intervals over a 24-hour period, typically using a portable device.

ABPM provides a more comprehensive assessment of blood pressure throughout daily activities and sleep, offering insights into variations that may not be detected in clinic settings.

ABPM is recommended for patients suspected of having white coat hypertension, masked hypertension, resistant hypertension, or fluctuating blood pressure patterns.

The patient wears a small cuff attached to a portable monitor that automatically inflates and records blood pressure at regular intervals, usually every 15-30 minutes during waking hours and less frequently during sleep.

Most patients find ABPM comfortable, as the device is lightweight and designed for minimal disruption to daily activities. The cuff may inflate periodically but does not cause pain.

Common reasons include chronic sinusitis, nasal polyps, blocked sinus passages, and recurrent sinus infections that do not respond to other treatments.

The surgery typically lasts between 1.5 to 3 hours, depending on the complexity of the procedure.
