Bleeding from the nose [1] Usual onset: Less than 10 and over 50 years old [2] Risk factors: Trauma, excessive nose picking, certain infections, blood thinners, high blood pressure, alcoholism, seasonal allergies, dry weather [3] Diagnostic method: Direct observation [1] Differential diagnosis: Bleeding from the lungs, esophageal varices, [1 ...
The sphenopalatine artery is the artery commonly responsible for epistaxis (difficult to control bleeding of the nasal cavity, especially the posterior nasal cavity). [3] In severe nose bleed cases which do not stop after intense packing of anti-clotting agents, the sphenopalatine artery can be ligated (clipped and then cut) during open surgery ...
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.
In medicine, the mean arterial pressure (MAP) is an average calculated blood pressure in an individual during a single cardiac cycle. [1] Although methods of estimating MAP vary, a common calculation is to take one-third of the pulse pressure (the difference between the systolic and diastolic pressures), and add that amount to the diastolic pressure.
Arterial bleeding: As the name suggests, blood flow originating in an artery. With this type of bleeding, the blood is typically bright red to yellowish in colour, due to the high degree of oxygenation. Blood typically exits the wound in spurts, rather than in a steady flow; the blood spurts out in time with the heartbeat. The amount of blood ...
Ninety percent of nosebleeds (epistaxis) occur in Kiesselbach's plexus, whereas five to ten percent originate from Woodruff's plexus. [3] It is exposed to the drying effect of inhaled air. [3] It can also be damaged by trauma from a finger nail (nose picking), as it is fragile. [3] [4] It is the usual site for nosebleeds in children and young ...
A Delta Airlines flight had to return minutes after takeoff as passengers’ noses began bleeding when the cabin failed to pressurize as it climbed high into the air.. The Boeing 737-900 plane ...
A minimum systolic value can be roughly estimated by palpation, most often used in emergency situations, but should be used with caution. [10] It has been estimated that, using 50% percentiles, carotid, femoral and radial pulses are present in patients with a systolic blood pressure > 70 mmHg, carotid and femoral pulses alone in patients with systolic blood pressure of > 50 mmHg, and only a ...
