Definition and causes

ARDS is an outbreak mode in which the lungs can not absorb as much oxygen as the body needs. At the same time, the carbon dioxide that are produced in the body, not aired out. There are massive shortness of breath, and the person may be blue around the lips and nails and lose in the worst cases awareness. Tilstanden has many names and called in particular alsoacute lungesvigtorshocklunger.

The causes of ARDS may be many, but in general it is that any dramatic effect on the lung may trigger ARDS. When the lung somehow damaged, luftblærerne and the small blood vessels leaking and leaking fluid and proteins (see Lungerne and airways ). This leads to a pulmonary oedema (water in the lungs), and it will be harder for oxygen to pass from the air and into the blood. There's also a betændelsesagtig reaction, and lose surfaktant. Surfaktant is the substance that normally helps to keep the small luftblærer open. The lack of surfaktant applauding luftblærerne easily together, and there can not exchange oxygen and carbon dioxide in the area.

Examples of reasons that may trigger ARDS:

  • Viral infection (sepsis) That affects all the body's organs.

  • Nærdrukning: It means that you have been very close to drowning.

  • Severe trauma, for example. road accidents, explosions or exposure to extreme heat or cold.

  • Inhalation of toxic gases such as. klordampe or smoke from a fire.

  • Illness in other bodies, for example. large blood loss, anaphylactic shock or acute bugspytkirtelbetændelse .

  • Stay in 4-5 kilometers into account (not applicable to aircraft, which usually have a pressurised cabin).

Symptoms of ARDS

Hours after the adverse effects can be seen the following:

  • Cough.

  • Fast breathing.

  • Shortness of breath.

  • Anxiety, fear and confusion.

  • Blåfarvning of special lips and neglelejer.

  • Possibly. bubbly breathing.

Precautions and diagnosis

If you have been exposed to one of the above operative influences, one should consult a doctor as soon as possible, even if you do not have any symptoms at the time. This is because the symptoms often show up only after a few hours, and when they arise, they can develop very quickly.

The doctor will interview about what it is, you have been exposed to and how long. There is a so-called pulsoximeter on a pier that can measure iltmætningen in the blood. Often made also a arteriepunktur, which is a blood sample from an artery in the wrist. A arteriepunktur provide many valuable information on oxygen and carbon dioxide in the blood. There is also an X-ray of the lungs, where you can see that the lungs are more white than normal. If the lungs are completely white, it is a very serious sign that

Consideration of ARDS

As far as possible be the operative cause exists, then we can target the treatment after that. In all cases, however, give oxygen at a special mask. There must be given so much that iltmætningen in the blood is kept above 90%. If the oxygen mask on is not enough, there is a need for respiratory. It will often make sure to set respiratoren, so there is always a slight excess in the airways. This runs counter to several luftblærer coincide and can open some of those already folded sam

Select and complications

ARDS is a very serious condition, which may end with death if treatment begins with the same. Even with the timely and proper treatment, in the worst case be impossible to save their lives. How severe ARDS is depends in part on what triggered the state, where blood poisoning (sepsis) and large blood loss are some of the most serious. If we survive ARDS, the lungs usually recover completely within a few months.
