A wearable blood pressure measurement apparatus includes a measurement apparatus body, a binding component, an inflation component, a gas pressure sensor, a gas bag and a pressure sensor. The pressure sensor is configured to collect a current pressure value of the binding component, the measurement apparatus body is configured to determine whether the current pressure value is greater than a preset first pressure threshold, the inflation component is configured to inflate the gas bag, the gas pressure sensor is configured to collect a current gas pressure value of the gas bag, the measurement apparatus body is further configured to, when the current gas pressure value reaches a preset gas pressure threshold, determine inflation duration of the gas bag, and determine whether the inflation duration is greater than a preset first duration threshold.
