Neurogenic shock is a distributive type of shock resulting in hypotension (low blood pressure), often with bradycardia (slowed heart rate), caused by disruption of autonomic nervous system pathways. [1] It can occur after damage to the central nervous system, such as spinal cord injury and traumatic brain injury.
Cold shock response is a series of neurogenic cardio-respiratory responses caused by sudden immersion in cold water. In cold water immersions, such as by falling through thin ice, cold shock response is perhaps the most common cause of death. [ 1 ]
Central neurogenic hyperventilation (CNH) is an abnormal pattern of breathing characterized by deep and rapid breaths at a rate of at least 25 breaths per minute. Increasing irregularity of this respiratory rate generally is a sign that the patient will enter into coma .
Distributive shock is a medical condition in which abnormal distribution of blood flow in the smallest blood vessels results in inadequate supply of blood to the body's tissues and organs. [ 1 ] [ 2 ] It is one of four categories of shock , a condition where there is not enough oxygen -carrying blood to meet the metabolic needs of the cells ...
Septic shock, especially septic shock where treatment is delayed or the antimicrobial drugs are ineffective, however has a mortality rate between 30% and 80%; cardiogenic shock has a mortality rate of up to 70% to 90%, though quick treatment with vasopressors and inotropic drugs, cardiac surgery, and the use of assistive devices can lower the ...
The underlying mechanism involves the nervous system slowing the heart rate and dilating blood vessels, resulting in low blood pressure and thus not enough blood flow to the brain. [2] Diagnosis is based on the symptoms after ruling out other possible causes. [3] Recovery from a reflex syncope episode happens without specific treatment. [2]
The three criteria for the qSOFA score include a respiratory rate greater than or equal to 22 breaths per minute, ... adrenal insufficiency, and neurogenic shock. ...
The annual rate of ARDS is generally 13–23 people per 100,000 in the general population. [42] It is more common in people who are mechanically ventilated with acute lung injury (ALI) occurring in 16% of ventilated people. Rates increased in 2020 due to COVID-19, with some cases also appearing similar to HAPE. [43] [44]
