Final answer:
Savannah's doctors are likely using biofeedback to help her manage her panic attacks, a technique that measures and provides feedback on involuntary bodily functions to gain control over them.
Step-by-step explanation:
The question Savannah's doctors are more than likely using biofeedback to help her control her panic attacks is aimed at finding out the technique commonly used to manage and control the symptoms of panic attacks. Biofeedback is a technique developed in the early 1970s by Gary Schwartz at Harvard University which utilizes electronic equipment to measure a person's neuromuscular autonomic activity and provides feedback in the form of visual or auditory signals. This feedback helps individuals gain voluntary control over normally involuntary bodily functions. Biofeedback has been applied successfully to individuals experiencing tension headaches, high blood pressure, asthma, and phobias, making it a suitable method for helping Savannah control her panic attacks.
