  2. Hypotension - Wikipedia

    en.wikipedia.org/wiki/Hypotension

    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 ...

  3. Orthostatic hypotension - Wikipedia

    en.wikipedia.org/wiki/Orthostatic_hypotension

    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 ...

  4. Permissive hypotension - Wikipedia

    en.wikipedia.org/wiki/Permissive_hypotension

    Permissive hypotension or hypotensive resuscitation [1] is the use of restrictive fluid therapy, specifically in the trauma patient, that increases systemic blood pressure without reaching normotension (normal blood pressures). The goal blood pressure for these patients is a mean arterial pressure of 40-50 mmHg or systolic blood pressure of ...

  5. Blood pressure - Wikipedia

    The macula densa causes an increase in Na + reabsorption, which causes water to follow in via osmosis and leads to an ultimate increase in plasma volume. Further, the macula densa releases adenosine which causes constriction of the afferent arterioles. At the same time, the juxtaglomerular cells sense the decrease in blood pressure and release ...

  6. Obstructive shock - Wikipedia

    en.wikipedia.org/wiki/Obstructive_shock

    The lung collapses, impairing normal breathing. Surrounding structures may also shift. When severe enough to cause these shifts and hypotension, it is called a tension pneumothorax. This is life-threatening. The increased pressure inside the chest can compress the heart and lead to a collapse of the blood vessels that drain to the heart.

  7. Feline arterial thromboembolism - Wikipedia

    en.wikipedia.org/wiki/Feline_arterial_thrombo...

    Up to 17% of cats with HCM experience arterial thromboembolism, but cats with other cardiomyopathies are also at increased risk. Cats with abnormally increased hemostasis, which can occur with hyperthyroidism, tumors, extensive inflammation, blood poisoning (sepsis), injury, or disseminated intravascular coagulation, represent another risk ...

  8. Hypertension - Wikipedia

    en.wikipedia.org/wiki/Hypertension

    If a cat has other problems such as kidney disease or retina detachment then a blood pressure below 160 mmHg may also need to be monitored. [ 188 ] Normal blood pressure in dogs can differ substantially between breeds but hypertension is often diagnosed if systolic blood pressure is above 160 mmHg particularly if this is associated with target ...

  9. Vitamin B12 deficiency - Wikipedia

    en.wikipedia.org/wiki/Vitamin_B12_deficiency

    Macular degeneration is the leading cause of severe, irreversible vision loss in older adults. [91] [92] Several risk factors have been linked to macular degeneration, including family history, genetics, hypercholesterolemia, hypertension, sunlight exposure and lifestyle (smoking and diet).
