Pulmonary Artery Hamorrhage Research Paper

 Arterial haemorrhage is Pulsatile and Bright red alsoBleeds from proximal ends ,porting as a jet that rises and drops in time with the pulse. In protracted bleeding, and when quantities of intravenous fluids else than blood are given, it may become watery in appearance.
 Venous haemorrhage is a dark red, a steady and copious flow. The color darkens still further from excessive oxygen desaturation when there is severe lose of blood, or in respiratory depression or obstruction. Blood loss is particularly rapid and when large veins are opened, example. common femoral or jugular.
 Venous bleeding can be under increased pressure as in asphyxia, or from ruptured varicose veins. Portal vein pressures are high enough to cause rapid blood loss, especially in portal hypertension with oesophageal
 varies. Pulmonary artery haemorrhage is dark red (venous blood) at around 30 mmHg (4 kPa), while bleeding from the pulmonary veins is bright red (oxygenated).
 Capillary haemorrhage is bright red, often rapid, ooze. If it continued for many hours, blood loss may become
The precipitating circumstances are: (1) the rise in blood pressure and the refilling of the venous system on recovery from shock; and (2) restlessness, coughing and vomiting which raise the venous pressure
 Venous haemorrhage, whether its primary or reactionary, can be taxing the skill of even an experienced surgeon, for it may be exceedingly difficult to bring under control. Penetrating wounds involving main veins in the thigh or groin are potentially fatal, as exsanguination can follow the removal of a first aid dressing which has apparently controlled the bleeding (butcher’s thigh). Such a wound should never be treated in a perfunctory manner; it requires careful examination and closure in an operating
