Negative pressure balloon drainage more than 100 times a day is not common or normal, and the frequency of drainage should be adjusted according to the condition of the wound and the treatment plan.

The wound has severe exudate or secretion and fluid drainage should be controlled continuously. It also suggests that the patient has medical problems such as infection and inflammatory flare-ups.
