Abstract: In some embodiments, a wearable device detects a trigger event. The trigger event indicates a type of measurement to take. Based on the trigger event, the wearable device selects an instruction audio message corresponding to the type of measurement to be taken. The instruction audio message includes instructions for how to conduct the type of measurement. The wearable device connects to an appropriate measuring apparatus based on the type of measurement to be taken and the instruction audio message. The wearable device plays the instruction audio message to a patient of the wearable device. The wearable device receives measurements from the appropriate measuring apparatus.
