  1. Pleural effusion
    is excess fluid that accumulates between the two pleural layers, the fluid-filled space that surrounds the lungs. Excessive amounts of such fluid can impair breathing by limiting the expansion of the lungs during ventilation.
  2. PNA
  3. Atrial fibrillation (AFor A-fib)
    is the most common cardiac arrhythmia (heart rhythm disorder). It may cause no symptoms, but it is often associated with palpitations, fainting, chest pain, or congestive heart failure. However, in some people atrial fibrillation is caused by otherwise idiopathic or benign conditions.AF increases the risk of stroke.
  4. Malaise
    is a feeling of general discomfort or uneasiness, of being "out of sorts", often the first indication of an infection or other disease.
  5. Ischemic stroke
    Ischemic stroke occurs as a result of an obstruction within a blood vessel supplying blood to the brain. It accounts for 87 percent of all stroke cases.
  6. Hemorrhagic stroke
    Hemorrhagic stroke occurs when a weakened blood vessel ruptures. Two types of weakened blood vessels usually cause hemorrhagic stroke: aneurysms and arteriovenous malformations (AVMs). But the most common cause of hemorrhagic stroke is uncontrolled hypertension (high blood pressure).
  7. TIA (transient ischemic attack)
    TIA (transient ischemic attack) is caused by a temporary clot. Often called a “mini stroke”, these warning strokes should be taken very seriously.
  8. Diaphoretic
    perspiring profusely
  9. Tachypneic
    Increase rate of respiration
  10. STEMI
    A ST-Elevation Myocardial Infarction (STEMI) is a very serious type of heart attack during which one of the heart’s major arteries (one of the arteries that supplies oxygen and nutrient-rich blood to the heart muscle itself) is blocked.
  11. Hypoxia
    Hypoxia, or hypoxiation, is a pathological condition in which the body as a whole (generalized hypoxia) or a region of the body (tissue hypoxia, or less commonly regional hypoxia) is deprived of adequate oxygen supply.
  12. Sepsis
    Sepsis (/ˈsɛpsɨs/; from the Greek σῆψις: the state of putrefaction and decay) is a potentially deadly medical condition characterized by a whole-body inflammatory state (called a systemic inflammatory response syndrome or SIRS) caused by severe infection.[1][2] Septicemia (or septicaemia or septicæmia [ˌsɛptɨˈsi:miə])[3] is a related medical term referring to the presence of pathogenic organisms in the bloodstream, leading to sepsis.[4] The term has not been sharply defined. It has been inconsistently used in the past by medical professionals, for example as a synonym of bacteremia, causing some confusion.[2]Sepsis is caused by the immune system's response to a serious infection, most commonly bacteria, but also fungi, viruses, and parasites in the blood, urinary tract, lungs, skin, or other tissues. Sepsis can be thought of as falling within a continuum from infection to multiple organ dysfunction syndrome.[5]Common symptoms of sepsis include those related to a specific infection, but usually accompanied by high fevers, hot, flushed skin, elevated heart rate, hyperventilation, altered mental status, swelling, and low blood pressure. In the very young and elderly, or in people with weakened immune systems, the pattern of symptoms may be atypical, with hypothermia and without an easily localizable infection.[6][7] Sepsis causes millions of deaths globally each year.[8]Sepsis is usually treated with intravenous fluids and antibiotics. If fluid replacement isn't sufficient to maintain blood pressure, vasopressors can be used. Mechanical ventilation and dialysis may be needed to support the function of the lungs and kidneys, respectively. To guide therapy, a central venous catheter and an arterial catheter may be placed; measurement of other hemodynamic variables (such as cardiac output, mixed venous oxygen saturation or stroke volume variation) may also be used. Sepsis patients require preventive measures for deep vein thrombosis, stress ulcers and pressure ulcers, unless other conditions prevent this. Some might benefit from tight control of blood sugar levels with insulin (targeting stress hyperglycemia).[8] The use of corticosteroids is controversial.[9] Activated drotrecogin alfa (recombinant activated protein C), originally marketed for severe sepsis, has not been found to be helpful, and has recently been withdrawn from sale.[10]
  13. ADR
    Adverse Drug Reaction
  14. Aphasia
    Aphasia "speechlessness"[2]) is a disturbance of the comprehension and formulation of language caused by dysfunction in specific brain regions.[3][4] This class of language disorder ranges from having difficulty remembering words to losing the ability to speak, read, or write.
  15. Hyperthermia
    Hyperthermia is elevated body temperature due to failed thermoregulation that occurs when a body produces or absorbs more heat than it dissipates. Extreme temperature elevation then becomes a medical emergency requiring immediate treatment to prevent disability or death.The most common causes include heat stroke and adverse reactions to drugs. The former is an acute temperature elevation caused by exposure to excessive heat, or combination of heat and humidity, that overwhelms the heat-regulating mechanisms. The latter is a relatively rare side effect of many drugs, particularly those that affect the central nervous system. Malignant hyperthermia is a rare complication of some types of general anesthesia.Hyperthermia can also be deliberately induced using drugs or medical devices and may be used in the treatment of some kinds of cancer and other conditions, most commonly in conjunction with radiotherapy.[1]Hyperthermia differs from fever in that the body's temperature set point remains unchanged. The opposite is hypothermia, which occurs when the temperature drops below that required to maintain normal metabolism.
