Final answer:
The abnormality that helps identify children with acute respiratory distress caused by lung tissue disease is a reduced ability to take in or expel air from the lungs. This can be detected using spirometry, which measures the rate at which air can be taken into or expelled from the lungs.
Step-by-step explanation:
The abnormality that helps identify children with acute respiratory distress caused by lung tissue disease is a reduced ability to take in air or expel air from the lungs.
This can be detected using spirometry, which measures the rate at which air can be taken into or expelled from the lungs. A diagnosis of a restrictive disease can be made if the spirometry results show abnormal lung function.
