Based on our results, evaluation of the shape of an elevated diaphragm may preclude the need for fluoroscopic sniff test to determine diaphragmatic paralysis. o [ pediatric abdominal pain ] In bilateral diaphragmatic paralysis, accessory muscles assume some or all of the work of breathing by contracting more intensely. Progressive reduction of tidal volumes during the test is consistent with neuromuscular abnormalities but also occurs with gas trapping as a result of disorders that cause airflow limitation. for: Medscape. 1984 Sep;22(3):615-31.

During the sniff test, we often note that there is a directional . Clipboard, Search History, and several other advanced features are temporarily unavailable.
