Study Notes

Unconsciousness

Unconsciousness is a state of complete unresponsiveness.
A victim is unconscious when they do not talk, react, or move when asked, but are breathing normally.
Causes of unconsciousness include traumatic, medical, and toxic factors.
Examples of causes include seizure, cerebrovascular issues, tumors, cardiac arrest, heart or lung disease, asphyxiation, alcohol consumption, carbon monoxide poisoning, drug use, and infections.
Pathophysiology involves direct compression or destruction of brain structures, reduced oxygen or glucose availability, and toxic effects of substances on the reticular activating system (RAS).
Unconsciousness poses a risk of progression to respiratory and circulatory arrest, as breathing requires clear airways.
Someone lying on their back may have difficulties breathing due to saliva, blood, and stomach fluids obstructing the airways; the tongue may also fall back.
The priority when encountering an unconscious individual is opening the airways.

Objectives

Identify victims displaying signs of unconsciousness.
Keep the unconscious victim's airways clear until emergency assistance arrives.

Consciousness

Consciousness is the normal wakefulness dependent on the interaction of a functioning cerebral cortex and an intact reticular activating system.
Key characteristics include orientation to time, place, and person; alertness and wakefulness; awareness of the environment; ability to answer questions appropriately; and intact recent and remote memory.

Altered Level of Consciousness

Confusion: Loss of clear thinking, impaired judgment, and decreased decision-making ability.
Disorientation: Confusion about time, place, or self; impaired memory.
Coma: Complete unresponsiveness, regardless of stimulus, lack of motor or verbal responses, and no response to noxious stimuli.

Assessment

Look (ALERTNESS): Observe for alertness using the AVPU scale. Shake the victim's shoulder and call out loudly; check for chest movement.
Listen: Assess for heart sounds.
Feel: Check for air passage through the nostrils.
AVPU scale stands for:
A - Alert (and conscious)
V - Responds to verbal stimuli
P - Responds to painful stimuli
U - Unresponsive.

First Aid Management

If there's no heart sound or breathing (cardiac arrest), initiate Cardiopulmonary Resuscitation (CPR).
Seek immediate help.
Perform chest compressions.

Opening the Airway

Place the victim on their back.
Open the airway by tilting the head, lifting the chin, or using the jaw thrust to ensure unobstructed breathing passage.
Cover the victim's mouth completely.
Deep breath two times.
Airways must be open to allow victims to breathe.

Recovery Position

Safe and appropriate place.
Left lateral position with the right arm under the chin.
Right leg folded up to the abdomen, and left leg straightened.
Continuous monitoring is essential.
Referral to a hospital may be necessary.
The recovery position helps prevent choking and maintain breathing.

Exception (Pregnant women)

Position the pregnant woman on her left side during recovery.
This prevents pressure on blood vessels in the abdomen, which is more critical for pregnant women.

Exception (Infants)

Check consciousness by tapping or flicking the infant's foot or shoulder.
Use the same process to open airways as adults and children but don't tilt the head too much.
Ensure the infant's face is parallel to the ground

Emergency Procedures

Alert others to notify emergency services, especially when alone.
Protect victims from the cold, heat, or bad weather while waiting for emergency services.
Observe breathing patterns and chest movements.
If breathing stops, reposition the victim and initiate CPR.
