Hypotension, also known as low blood pressure, is a cardiovascular condition characterized by abnormally reduced blood pressure. [1] Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood [2] and is indicated by two numbers, the systolic blood pressure (the top number) and the diastolic blood pressure (the bottom number), which are the ...
The concomitant presence of hypoxia and hypotension upon admission resulted in a 75% mortality. [20] Evidence strongly suggests that the avoidance or minimization of hypotension during the acute and postinjury period following traumatic brain injury had the highest likelihood of improving outcomes of any one single therapeutic maneuver. [21]
Some causes of orthostatic hypotension include neurodegenerative disorders, low blood volume (e.g. caused by dehydration, bleeding, or the use of diuretics), drugs that cause vasodilation, other types of drugs (notably, narcotics and marijuana), discontinuation of vasoconstrictors, prolonged bed rest (immobility), significant recent weight loss ...
People may also have a severely low blood pressure and heart rate. Causes of cardiogenic shock include cardiomyopathic, arrhythmic, and mechanical. Cardiogenic shock is most commonly precipitated by a heart attack. [4] Treatment of cardiogenic shock depends on the cause with the initial goals to improve blood flow to the body.
Causes: Hypotension, hypoglycaemia, arrhythmia, anaemia, hypokalaemia, thrombosis, water intoxication, dehydration: Risk factors: Poor dietary or diabetic management, genetic predisposition to cardiac arrhythmia: Diagnostic method: Based on symptoms. Some thrombotic pre-syncope may be indicated by a troponin serum level. Treatment: Dependent on ...
Shock is the state of insufficient blood flow to the tissues of the body as a result of problems with the circulatory system.Initial symptoms of shock may include weakness, tachycardia, hyperventilation, sweating, anxiety, and increased thirst. [1]
The most common risks factors that can potentially cause IRDS include male gender, white race, late preterm delivery, maternal diabetes, perinatal hypoxia (exposure to low oxygen) and ischemia (decreased blood flow), and low birth weight. [40] Seventy percent of babies diagnosed with respiratory distress syndrome are born between 29 and 34 ...
Patent ductus arteriosus (PDA) is a medical condition in which the ductus arteriosus fails to close after birth: this allows a portion of oxygenated blood from the left heart to flow back to the lungs from the aorta, which has a higher blood pressure, to the pulmonary artery, which has a lower blood pressure.
