Yes, severe PAD is indicated with a warning and the PAD symbol.
If the patient has severe PAD, the pulse in the ankles is very weak. This means the ABI cannot be accurately calculated. Instead, the device will analyze the pulse waveform and indicate severe disease with a PAD symbol. In the case of a PAD result, we always recommend repeating the measurement with the device connected to the computer. This provides the full-length pulse waveform, which can be analyzed to confirm the condition.
