Under Acute Respiratory Distress Syndrome Doctors understand acute lung failure in the patient. This sudden breathlessness is also known under the abbreviation ARDS. The disease must have an identifiable and noncardiac cause.
Doctors understand acute respiratory distress syndrome to mean acute lung failure in the patient.
This so-called shock lung is caused by inflammation of the lung tissue, which can be caused by various factors. The consequences of not timely treatment can be: shock, unconsciousness up to organ failure and heart failure.
Acute Respiratory Distress Syndrome describes the strong reaction of the lungs to various damaging factors. The disease Acute Respiratory Distress Syndrome is characterized by multifactorial damage to the lungs with the formation of pulmonary edema and a subsequent oxygenation disorder.
Acute lung failure, the so-called shock lung, describes sudden shortness of breath caused by damage to the lungs. The affected person gets very poor air, whereby the carbon dioxide content in the blood increases and the oxygen content decreases. The possible consequences of untimely treatment include: unconsciousness, shock, or even failure of organs and the heart.
Acute Respiratory Distress Syndrome is caused by inflammation of the lung tissue, which can be caused by various factors. The previous illnesses can be quite different, for example pneumonia, injuries, poisoning. The main causes include inhaling harmful substances such as smoke or sucking in various substances such as gastric fluids.
Indirect effects such as coagulation disorders or injuries can lead to Acute Respiratory Distress Syndrome. This results in pulmonary edema because the blood vessels become more permeable within the alveoli. This leads to a pressure drop in some vascular areas of the lung tissue. At the same time, there is an increase in pressure in other parts. In addition, proteins escape, which significantly reduces the oxygen supply to the blood and increases the carbon dioxide content.
Acute Respiratory Distress Syndrome, in most cases, develops about 24 to 48 hours after the original injury or illness occurs. The person concerned initially experiences shortness of breath, which is usually accompanied by rapid, shallow breathing. The doctor may hear crackling or wheezing in the lungs with a stethoscope.
The skin may appear blotchy or blue (cyanosis) due to the low level of oxygen in the blood. Other organs, such as the heart and brain, may malfunction, such as a fast heart rate, irregular heartbeat, confusion and lethargy.
Acute Respiratory Distress Syndrome usually begins with the following symptoms: Due to the damage to the lung tissue, the patient initially feels difficult breathing. He begins to breathe faster so that he can counter this. This leads to hyperventilating.
The lips and fingernails can turn blue after a while. Doctors differentiate between three phases:
Most of the lung tissue has stopped working due to the inflammation. Depending on the extent, the low oxygen content can have various consequences, which can range from unconsciousness, shock, organ failure and heart failure. The doctor usually makes the diagnosis of ARDS based on the previous illness.
When listening to the lungs, the first signs become apparent, because a rattling sound is heard. A subsequent x-ray examination can provide a more accurate diagnosis. This shows possible deposits in the alveoli, which can be a clear indication of an incipient shock lung.
The adult acute respiratory distress syndrome, often referred to as shock lung, is associated with an extreme inflammatory reaction of the lungs and lung tissue. This causes a pathological chain of reactions that leads to a number of complications.
Initially, lung edema often forms due to the lung damage caused by inflammation. The cause is the increase in the permeability of the capillaries. This inflammatory reaction also leads to the immigration of certain white blood cells, which release lytic enzymes and oxygen radicals, thus increasing the original inflammation.
If the patient is not or not successfully treated, these inflammatory mediators cause the next stage to further increase the permeability of the capillaries. This often results in alveolar edema, i.e. an edema affecting the alveoli. In the next stage, the surfactant, a kind of protective substance on the alveoli, is destroyed.
This leads to further serious complications. As a rule, atelectasis, i.e. a lack of ventilation in the lungs or in individual parts of the lungs, is the consequence. As a result, the oxygenation of the blood and thus the oxygen supply to the brain and other organs is extremely deteriorated.
At this stage, respiratory distress syndrome is usually fatal. If the patient survives, there are usually further complications in the healing process. Often the body can only replace the destroyed lung tissue with connective tissue. The oxygen supply to the body is permanently reduced.
In the case of an acute "respiratory distress" syndrome, i.e. acute shortness of breath due to the onset of lung failure, an immediate visit to the doctor or the immediate calling of the emergency doctor is essential. It is a relatively sudden onset of lung failure that requires immediate treatment. The so-called shock lung can lead to death within a short time if left untreated.
Acute Respiratory Distress Syndrome is a dramatic emergency. The affected person will probably quickly pass out due to the sudden onset of shortness of breath. Without medical help, the patient will not be able to survive this emergency.
On the one hand, the person concerned must be ventilated immediately so that the carbon dioxide content in the blood drops. On the other hand, the cause of the acute respiratory distress syndrome must be determined as quickly as possible. This can best be done in a clinic, where the person concerned is given all the medical help he needs.
The attending physician may be aware of previous illnesses that could be the trigger. Otherwise, it is important for the anamnesis to have statements from those present who know what happened in the 24-48 hours before the onset of dyspnoea and lung failure. Acting quickly is particularly important in Acute Respiratory Distress Syndrome so that the failing lungs are not damaged worse. Delays are expected to result in complications.
The therapy of Acute Respiratory Distress Syndrome is intensive medical. Within a few hours, the disease can lead to respiratory decompensation with the need for ventilation. Decompensation occurs when a body can no longer compensate for the defects that have arisen from an illness. First and foremost, it is important to treat the triggering cause and to use mechanical ventilation at an early stage.
When ventilating the patient, there is often only a low pressure amplitude available in order to shift the tidal volume. Hypercapnia can occur as a result. In individual cases this must be tolerated. However, patients with increased intracranial pressure are an absolute contraindication. The therapeutic options for avoiding hypercapnia include high-frequency oscillation and extracorporeal lung support with a heart-lung machine.
Due to the increased risk of thrombosis in the event of immobilization a low-dose heparinization should be carried out. If possible, the patient is fed enterally via a central venous catheter or a gastric tube. Often both forms of nutrition must be used. The therapy requires intensive medical effort. In the late course of healing, the administration of glucocorticoids can reduce pulmonary fibrosis.
The Acute Respiratory Distress Syndrome is a very serious and dangerous condition for the patient and usually leads to death without treatment. This leads to severe breathing difficulties, which are often accompanied by a panic attack. Furthermore, direct lung failure can occur without treatment. As a result, organs are not supplied with enough oxygen and can be damaged. In the worst case, cardiac arrest occurs. Most patients also have hyperventilation and continued loss of consciousness due to Acute Respiratory Distress Syndrome.
The further course of the disease depends very much on the cause of the acute respiratory distress syndrome and on its treatment. Acute treatment by the emergency doctor can alleviate most of the symptoms and save the patient. Without treatment, the patient dies after a few minutes. If the air supply has been interrupted for a few minutes, various types of damage to the organs may have developed. In some cases this leads to paralysis or spasticity.
The best way to prevent acute respiratory distress syndrome is to intensively treat the underlying disease that can lead to acute lung failure. This is absolutely necessary so that it does not lead to breathing disorders. However, if lung failure does occur, it is important that it is recognized in good time to prevent serious consequences.
Therefore, it is very important that the doctor consider shock lung at the first signs of breathlessness for which there is no explanation. The shock lung is acute, life-threatening damage to the lungs. Therefore, in the event of unusual symptoms, a doctor should always be consulted who will determine the causes of the complaints.
Acute lung failure is always a life-threatening condition. Due to the drama of the event, patients with acute respiratory distress syndrome rarely experience the need for medical follow-up care. A large number of those affected die as a result of multiple organ failure. A systemic inflammatory process - a Systemic Inflammatory Response Syndrome or SIRS - is often present at the same time.
Acute Respiratory Distress Syndrome can have three degrees of severity. These are treated with different levels of intensity. The causes of ALRS are numerous. Accordingly, different follow-up measures may be required for mild acute respiratory distress syndromes than for moderate ones. In severe cases with advanced sepsis, severe burn injuries, or traumatic brain injury, death is almost always inevitable.
In some cases, even an advanced acute respiratory distress syndrome can be survived through the organism's self-healing mechanisms. But despite all intensive medical interventions, the survivors usually suffer from severe lung damage. These require permanent follow-up care. After surviving acute respiratory distress syndrome, those affected often require ventilation. You are much more susceptible to pneumonia, pulmonary fibrosis or blood poisoning.
The death rate is between 55 and 70 percent. ARDS patients who are permanently bedridden are little protected from the development of thromboses and embolisms. Follow-up care must take into account the high degree of risk to those affected.
People suffering from acute respiratory distress syndrome must be treated immediately by an emergency doctor. Until the ambulance service arrives, the person affected must be placed on the prone position and reassured. Resuscitation measures, such as mouth-to-mouth resuscitation or the use of a defibrillator, should be taken if breathing or cardiac arrest occurs.
The Acute Respiratory Distress Syndrome is a serious syndrome that requires medical treatment in any case. The affected person has to spend some time in the hospital after the emergency. If the outcome is positive, light physical activity can be resumed a few days to weeks after the procedure. In addition, the causes of the medical emergency must be determined and remedied.
Since acute respiratory distress syndrome is always the consequence of a protracted illness or a serious accident, the treatment focuses on symptomatic therapy, since a causal treatment is usually no longer possible. The curative or palliative medical measures can be supported by general measures such as physiotherapy, a diet and discussions with a suitable therapist.
