Creating an event listener that can detect changes to a specific field before or during a save action

I am facing a challenge in updating specific fields during a save operation, but only when one particular field is being modified. I'm unsure of how to achieve this.

Additional information: If a user is editing the 'is_activated' field in my model, I want to trigger the 'suspendToActive' function, otherwise it should not be executed.

Below is the current implementation of my save action:

public function save(Doctrine_Connection $conn = null)
      {
        if ($this->isNew() && !$this->getExpiresAt())
        {
                ... // 
        }

        elseif ($this->getIsActivated()) // this is where I'm having trouble...
        {
            suspendToActive();
        }      

    return parent::save($conn);        
  }

Any insights on resolving this issue would be greatly appreciated.

To utilize Event Listeners in Doctrine, it is recommended to implement your model's preUpdate() function and analyze the invokers data to determine if a value has been modified.
