Acute respiratory distress syndrome ARDS can originate from either the gas or vascular side of the alveolus. Although the portal for coronavirus disease COVID is inhalational, and alveolar infiltrates are commonly found on chest x-ray or computed tomography CT scan, the respiratory distress appears to include an important vascular insult that potentially mandates a different treatment approach than customarily applied for ARDS.
Respiratory failure results from inadequate gas exchange by the respiratory system , meaning that the arterial oxygen, carbon dioxide or both cannot be kept at normal levels. A drop in the oxygen carried in blood is known as hypoxemia ; a rise in arterial carbon dioxide levels is called hypercapnia. Respiratory failure is classified as either Type 1 or Type 2, based on whether there is a high carbon dioxide level, and can be either acute or chronic. The definition of respiratory failure in clinical trials usually includes increased respiratory rate, abnormal blood gases hypoxemia, hypercapnia, or both , and evidence of increased work of breathing. Respiratory failure causes an altered mental status due to ischemia in the brain.
Given a critically ill patient, the resident must be able to determine the presence or absence of respiratory failure, provide for its emergency support, and have a plan of action to subsequently investigate and manage the problem. These actions must be based on a sound knowledge of respiratory physiology, pathology, pathophysiology, and pharmacology. The loss of the ability to ventilate adequately or to provide sufficient oxygen to the blood and systemic organs. ARF can result from a variety of etiologies. It can result from primary pulmonary pathologies or can be initiated by extra-pulmonary pathology. Causes are often multifactorial. Acute respiratory failure can be caused by abnormalities in:.
Respiratory failure is a condition in which your blood doesn't have enough oxygen or has too much carbon dioxide. Sometimes you can have both problems. When you breathe, your lungs take in oxygen.
When a person has acute respiratory failure, the usual exchange between oxygen and carbon dioxide in the lungs does not occur. As a result, enough oxygen cannot reach the heart, brain, or the rest of the body. This can cause symptoms such as shortness of breath, a bluish tint in the face and lips, and confusion. Acute respiratory failure has many possible causes. The cause may be acute, including pneumonia , or chronic, such as amyotrophic lateral sclerosis ALS.
