If the vomiting reflex continues for an extended period with no appreciable vomitus, the condition is known as non-productive emesis or "dry heaves", which can be painful and debilitating. [citation needed] Color of vomit [16] Bright red in the vomit suggests bleeding from the esophagus
Esophagitis, esophageal varices, gastritis, cirrhosis or gastric ulcers for example, may bleed and produce coffee-ground vomitus. When unaccompanied by melena, hematemesis or a fall in hemoglobin with corresponding urea rises and creates an unstable reaction, and other causes of coffee ground vomitus need to be elucidated; for example, gastric stasis, bowel obstruction or ileus, that can cause ...

Various specialized investigations use the inhalation of known substances for diagnostic purposes. Examples include pulmonary function testing (e.g. nitrogen washout test, diffusion capacity testing (carbon monoxide, helium, methane)) and diagnostic radiology (e.g. radioactive xenon isotopes).
Retching (also known as dry heaving) is the reverse movement (retroperistalsis) of the stomach and esophagus without vomiting. [1] It can be caused by bad smells or choking, or by withdrawal from certain medications, or after vomiting has completed.
Furthermore, blood and vomitus in the airway may prove visualization of the vocal cords difficult rendering direct and video laryngoscopy, as well as fiberoptic bronchoscopy challenging. [46] Establishment of a surgical airway is challenging in the setting of restricted neck extension (such as in a c-collar ), laryngotracheal disruption, or ...
In patients at imminent risk of aspiration, tracheal intubation by a trained health professional provides the best protection. A simpler intervention that can be implemented is to lay the patient on their side in the recovery position (as taught in first aid and CPR classes), so that any vomitus produced by the patient will drain out their ...
Choking, also known as foreign body airway obstruction (FBAO), is a phenomenon that occurs when breathing is impeded by a blockage inside of the respiratory tract.An obstruction that prevents oxygen from entering the lungs results in oxygen deprivation.
