If Someone Suddenly Exhibits "Face Drooping or Arm Weakness", It Could Be a Sign of Stroke! Use the FAST Acronym to Quickly Screen for Stroke Symptoms! Learn Other Warning Signs of Stroke! Why Can "Recording the Time" Save a Life? Master the Correct Stroke Emergency Response Steps!

What would you do if a family member next to you suddenly couldn’t even say a simple “Hello” clearly?

During a stroke, every single minute of delay costs the brain approximately 1.9 million brain cells.

In a state of panic, many people make the wrong moves, such as feeding water, giving medicine, or even using a needle for bloodletting, which only pushes the situation into a more dangerous state.

Learning how to correctly recognize a stroke and dispelling fatal first-aid myths are life-saving skills that everyone should have.

What Warning Signs Does the Body Show When a Stroke Strikes?

The most prominent feature of a stroke is “suddenness”.

One second you are chatting and laughing, and the next second your body has a problem. The internationally recognized acronym for identification is FAST:

Letter	English	Test Method	Key Observation
F	Face	Ask the person to smile	Check if both sides of the face are symmetrical, and if there is a drooping corner of the mouth on one side
A	Arm	Ask the person to raise both arms	Check if one arm drifts downward weakly
S	Speech	Ask the person to say “The weather is very nice today”	Check if they are slurring their words, or completely unable to speak
T	Time	Record the exact hour and minute symptoms appeared	Immediately call 119, and inform them of the onset time

If any one of these three actions cannot be done, it is highly likely to be a stroke, and the patient must be sent to the hospital immediately.

Besides FAST, What Other Danger Signals Exist?

FAST can catch most strokes, but several other warning signs should not be ignored either:

Signal	Explanation
Sudden numbness on one side of the body	Sudden loss of sensation on one side of the face, arm, or leg, unlike the feeling of a limb falling asleep
Sudden vision abnormalities	Sudden loss of vision in one eye, like a black curtain falling; or seeing double images
Sudden trouble walking	Staggering as if drunk, with difficulty even standing steadily
Explosive, severe headache	Unprecedented severe pain, like being struck by lightning, commonly seen in hemorrhagic stroke
Sudden difficulty understanding speech	Hearing is normal, but the brain seems to freeze and cannot comprehend what others are saying

Can We Perform Bloodletting for a Stroke? Is Feeding Water or Medication OK?

When facing an emergency, elders often say “quickly prick the fingers with a needle for bloodletting” or “give them a blood pressure pill to swallow.”

These folk remedies are not only useless, but can also be fatal.

Three Fatal Myths

Myth	Reality	Why It Is Dangerous
Pricking fingers to let blood clears blood vessels	Bloodletting cannot clear the blood clot inside cerebral blood vessels	Painful stimulation can make blood pressure spike even higher, accelerating the worsening of hemorrhagic stroke
Quickly feed water or food	The swallowing nerves might already be damaged during a stroke	Water and food can easily be choked into the lungs, leading to aspiration pneumonia or even suffocation
Administer blood pressure medicine on your own	During ischemic stroke, the brain intentionally raises blood pressure to save itself	Lowering blood pressure without authorization makes the brain more oxygen-deprived, and the damaged area expands instead

Where Did the Saying of Bloodletting Come From?

From the perspective of Traditional Chinese Medicine, the technique of pricking fingers to let blood is called Shi Xuan Bloodletting, but it is not used for emergency rescue of stroke.

Shi Xuan Bloodletting uses stimulation of peripheral nerves to keep the patient awake. This is a medical procedure and should only be performed by a professional practitioner of TCM after determining it is an ischemic stroke.

For ordinary people to perform this at home, the risks far outweigh the benefits.

What Are the Correct Stroke Emergency Response Steps?

The only correct way is simple, but must be executed calmly and rapidly:

Step	What to Do	Why It Matters
Step 1	Immediately call 119	Emergency medical personnel are on the ambulance and can notify the hospital’s Stroke Green Channel in advance to prepare
Step 2	Precisely record “the last time they were seen normal”	The doctor needs this time to decide whether the life-saving drug can be administered
Step 3	Place the patient on their side	Prevents vomit or the tongue from blocking the trachea to avoid suffocation
Step 4	Loosen tight clothing like collars and neckties	Keep the airway unobstructed
Step 5	Stay by their side and soothe their emotions	Anxiety will cause blood pressure to spike higher, worsening brain damage

Do not feed anything, do not move the patient’s head, and do not drive to a small clinic on your own.

If you must transport the patient yourself, go directly to a large hospital equipped with stroke emergency response capabilities, do not waste time sending them to a general clinic.

Why Can “Recording the Time” Save a Life?

You might wonder, why is the last letter of the FAST acronym T (Time)?

Because the life-saving medicine for stroke has a strict time limit.

Time Decides What Weapons Doctors Can Use

Treatment Method	Time Limit	Working Principle
Intravenous Thrombolytic Agent (rt-PA)	Within 4.5 hours of onset	Use drugs to dissolve the blood clot blocking the blood vessel
Arterial Thrombectomy	Within 6 to 24 hours of onset	Insert a catheter into the brain blood vessel to physically pull out the blood clot

If the family cannot provide a clear time of onset, doctors do not dare to use the thrombolytic drug blindly, because administering it past the time limit will instead increase the risk of cerebral hemorrhage.

The “exact hour and minute” you record could be the only key to whether your family member can clear their blood vessels and save their brain cells.

What Happens After Reaching the Hospital?

The hospital will activate the Stroke Green Channel, and all examinations and treatments will be fast-tracked:

Time	Explanation
0-10 minutes	Nurses immediately measure blood sugar (to rule out hypoglycemia mimicking stroke), draw blood, and evaluate severity
10-25 minutes	Urgent transfer to Computed Tomography (CT) to confirm if the blood vessel is blocked or ruptured
25-45 minutes	The doctor decides on using a thrombolytic agent or thrombectomy based on CT results and onset time
Within 60 minutes	Administration of medication is completed, and the patient is transferred to the Stroke Intensive Care Unit for close monitoring

The international medical standard strives to complete “Door-to-Needle” within 60 minutes.

If Symptoms Clear Up Quickly, Do I Still Need to See a Doctor?

There is a condition called “Mini-Stroke” (Transient Ischemic Attack, TIA).

The symptoms are exactly the same as a stroke, but they usually recover on their own within a few minutes to 24 hours.

Never assume that because you feel better, everything is fine.

A mini-stroke is the ultimate ultimatum sent by the brain. It means that the cerebral blood vessels are already severely narrowed or have unstable plaques, and the probability of a major stroke occurring in the future is extremely high.

Even if symptoms disappear within a few minutes, you must go to the emergency room immediately for a complete examination, allowing the doctor to evaluate the condition of the blood vessels and intervene early.

Facing a stroke, the best preparation we can make is to engrave the FAST acronym in our minds, and bravely say no to folk remedies.

At the critical moment, your calm judgment and that phrase “when it started” can save your family member’s brain and future.
