Management of Unconsciousness Flashcards
What is unconsciousness?
Unconsciousness is when a person is unable to respond to people and activities.
What is the Reticular Activating System (RAS)?
The Reticular Activating System is a network in the brainstem responsible for maintaining consciousness.
What does ALOC stand for?
ALOC stands for Altered Level of Consciousness.
What are the characteristics of clouding of consciousness?
Clouding of consciousness involves inattention, decreased alertness, and reduced wakefulness.
What is confusion in the context of ALOC?
Confusion is a state of disorientation with difficulty following commands.
Define lethargy in the spectrum of altered levels of consciousness.
Lethargy is severe drowsiness where the patient can still be aroused with moderate stimuli.
What is obtundation, and how does it differ from lethargy?
Obtundation is similar to lethargy but with slower responses and decreased wakefulness.
What is stupor, and how is it different from other states of ALOC?
Stupor is when the patient can only be aroused by repeated and vigorous stimuli, such as pain.
What defines a coma in the spectrum of consciousness?
A coma is a persistent state of unresponsiveness despite attempts at arousal.
Name three vascular causes of unconsciousness.
Vascular causes include CVA, ruptured aneurysm, and infarction.
What metabolic conditions can lead to unconsciousness?
Metabolic conditions include diabetes mellitus, uraemia, liver failure, and hypoxia.
What is the importance of maintaining a patent airway in an unconscious patient?
Maintaining a patent airway prevents aspiration and ensures the patient can breathe.
What is the order of priority in managing the airway, breathing, and circulation in an unconscious patient?
The priority order is Airway, Breathing, and then Circulation.
What is the most common cause of airway obstruction in unconscious patients?
The most common cause of airway obstruction in unconscious patients is the posterior displacement of the tongue.
How do you assess if the airway is obstructed?
Airway obstruction is assessed by gurgling, snoring, stridor, or apnea.
