Hemoptysis or haemoptysis is the discharge of blood or blood-stained mucus through the mouth coming from the bronchi, larynx, trachea, or lungs. It does not necessarily involve coughing. It does not necessarily involve coughing.
A nosebleed, also known as epistaxis, is an instance of bleeding from the nose. [1] Blood can flow down into the stomach, and cause nausea and vomiting. [8] In more severe cases, blood may come out of both nostrils. [9] Rarely, bleeding may be so significant that low blood pressure occurs. [1]
A rhinolith (from rhino- 'nose' and -lith 'stone') is a stone present in the nasal cavity. It is an uncommon medical phenomenon, not to be confused with dried nasal mucus. A rhinolith usually forms around the nucleus of a small exogenous foreign body, blood clot or secretion by slow deposition of calcium and magnesium carbonate and phosphate ...
Bleeding within the confines of the mucoperichnondrium leads to a septal hematoma, where as external bleeding from Kiesselbach's plexus results in epistaxis. [3] The Kiesselbach plexus is located anterior inferior of the nasal septum, where the anastomosis of blood vessels is located.
Haemolacria can manifest as tears ranging from merely red-tinged to appearing to be entirely made of blood, [1] and may also be indicative of a tumor in the lacrimal apparatus. It is most often provoked by local factors such as bacterial conjunctivitis , environmental damage or injuries. [ 2 ]
A nosebleed (epistaxis) usually occurs in the anterior part of the nose from an area known as Kiesselbach's plexus which consists of arteries. Woodruff's plexus is a venous plexus in the posterior part and a nosebleed here accounts for only between 5 and 10 per cent of nosebleeds. Older adults are most often affected. [5]
Exercise-induced pulmonary hemorrhage (EIPH), also known as "bleeding" or a "bleeding attack", is the presence of blood in the airways of the lung in association with exercise. EIPH is common in horses undertaking intense exercise, but it has also been reported in human athletes, racing camels and racing greyhounds .
Prior to nose blowing, a deep inhale through the mouth or nose provides the air required to eject the nasal mucus. Exhaling hard through both nostrils at once (or, if only one nostril is running, just the affected nostril) will effectively eject the mucus. [2] The process may need to be repeated several times to sufficiently clear the entire nose.
