One common sign of respiratory arrest is cyanosis, a bluish discoloration of the skin resulting from an inadequate amount of oxygen in the blood.If respiratory arrest remains without any treatment, cardiac arrest will occur within minutes of hypoxemia, hypercapnia or both.
Necrotizing pneumonia (NP), also known as cavitary pneumonia or cavitatory necrosis, is a rare but severe complication of lung parenchymal infection. [ 1 ] [ 2 ] [ 3 ] In necrotizing pneumonia, there is a substantial liquefaction following death of the lung tissue, which may lead to gangrene formation in the lung.
People who pursue aggressive treatment usually do not understand that their illness has reached a terminal stage, and they are pursuing treatment because they do not understand it to be futile. [ 7 ] Palliative care is normally offered to terminally ill patients, regardless of their overall disease management style, if it seems likely to help ...
Pneumonia is an inflammatory condition of the lung primarily affecting the small air sacs known as alveoli. [3] [14] Symptoms typically include some combination of productive or dry cough, chest pain, fever, and difficulty breathing. [15]
Without special treatment after circulation is restarted, full recovery of the brain after more than 3 minutes of clinical death at normal body temperature is rare. [6] [7] Usually brain damage or later brain death results after longer intervals of clinical death even if the heart is restarted and blood circulation is successfully restored ...
Of people who have multiple injuries with an injury severity score of over 15, pulmonary contusion occurs in about 17%. [20] It is difficult to determine the death rate because pulmonary contusion rarely occurs by itself. [17] Usually, deaths of people with pulmonary contusion result from other injuries, commonly traumatic brain injury. [24]
Ventilator-associated pneumonia (VAP) is a sub-type of hospital-acquired pneumonia (HAP) which occurs in people who are receiving mechanical ventilation. VAP is not characterized by the causative agents; rather, as its name implies, definition of VAP is restricted to patients undergoing mechanical ventilation while in a hospital.
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 the blood is known as hypoxemia ; a rise in arterial carbon dioxide levels is called hypercapnia .
