However, such measures can also increase leakage of air through a tear, and can stress the sutures in a tear that has been surgically repaired; therefore the lowest possible airway pressures that still maintain oxygenation are typically used. The use of high frequency ventilation has been reported. Mechanical ventilation can also cause pulmonary barotrauma when high pressure is required to ventilate the lungs. Techniques such as pulmonary toilet (removal of secretions), fluid management, and treatment of pneumonia are employed to improve pulmonary compliance (the elasticity of the lungs).While TBI may be managed without surgery, surgical repair of the tear is considered standard in the treatment of most TBI. It is required if a tear interferes with ventilation; if mediastinitis (inflammation of the tissues in the mid-chest) occurs; or if subcutaneous or mediastinal emphysema progresses rapidly; or if air leak or large pneumothorax is persistent despite chest tube placement. Other indications for surgery are a tear more than one third the circumference of the airway, tears with loss of tissue, and a need for positive pressure ventilation. Damaged tissue around a rupture (e.g. torn or scarred tissue) may be removed in order to obtain clean edges that can be surgically repaired. Debridement of damaged tissue can shorten the trachea by as much as 50%. Repair of extensive tears can include sewing a flap of tissue taken from the membranes surrounding the heart or lungs (the pericardium and pleura, respectively) over the sutures to protect them.
In the few cases where the father is the perpetrator, however, the victim is three times more likely to be male.One study in Italy found that 4 out of more than 700 children admitted to the hospital met the criteria (0.53%). In this study, stringent diagnostic criteria were used, which required at least one test outcome or event that could not possibly have occurred without deliberate intervention by the FDIA person.

Terminology
The term "Munchausen syndrome by proxy", in the United States, has never officially been included as a discrete mental disorder by the American Psychiatric Association, which publishes the Diagnostic and Statistical Manual of Mental Disorders (DSM), now in its fifth edition. Although the DSM-III (1980) and DSM-III-R (1987) included Munchausen syndrome, they did not include MSbP. DSM-IV (1994) and DSM-IV-TR (2000) added MSbP as a proposal only, and although it was finally recognized as a disorder in DSM-5 (2013), each of the last three editions of the DSM designated the disorder by a different name. FDIA has been given different names in different places and at different times.
