In addition, iodine solution irritates the mucosa and may cause retrosternal chest pain and discomfort; it is also limited by the occurrence of hypersensitivity and the risk of chemical esophagitis, laryngitis, and bronchopneumonia (17).
However, this modality may cause severe chest pain and discomfort owing to mucosal irritation (6, 20, 21, 22) and requires the examination of many biopsy specimens to obtain a definite pathological diagnosis (4, 5, 6, 7, 8).
Many other conditions may be present in these patients that could cause chest pain.
The superior vena cava (a large vein carrying circulating, de-oxygenated blood into the heart) may be compressed by a tumor, causing superior vena cava syndrome, which can cause chest wall pain among other symptoms.

8 9 Intubation attempts may cause interruptions in chest compressions, compromised oxygenation and delays in accessing definitive care.
Nonetheless, changes in respiratory muscle recruitment may cause alterations of chest wall configuration that would change NME between assisted and non-assisted breaths [ 15- 17].
