9 First Aid SOPs To Know In Case You Need To Save A Life One Day

First aid SOPs to know when medical emergencies happen

According to Murphy’s law, anything that can go wrong will go wrong. But whether or not you believe it, it’s always best to be prepared for the worst case scenario. The thought of one’s possible demise is terrifying – but what’s even more terrifying is the fact that not many people have a clue what to do when a medical crisis strikes. 

Beyond just dialling 995 and standing around, there’s more you can do as a bystander that can save someone’s life. So below is a breakdown of nine common emergency scenarios, complete with a step-by-step first aid guide on what to do. 

1. Heart attack

Years ago, my dad had a “silent” heart attack – and no, it didn’t look anything like the movies. He brushed it off since there was no dramatic falling or collapsing until unbearable pain pushed him to go to the doctor’s – just in time.

While visual cues aren’t always glaring, don’t mistake that for the absence of life-threatening danger – heart attacks can be as severe as health emergencies come. Once you hear a family member complain about pain or tightness in the chest that spreads to the arm and lower back, be sure to whisk that person off to emergency services ASAP.

If someone loses consciousness during a heart attack, below is the emergency SOP: 

  1. Call an ambulance
  2. Check for response and breathing by tapping on the person and looking for rise and fall of the chest
  3. If the person isn’t breathing, conduct CPR by pushing down hard and fast in the centre of the chest, at a rough pace of 100 to 120 compressions a minute
  4. Ask someone to grab an automated external defibrillator (AED) – a device that helps deliver an electric shock to restart the heart where necessary. This comes complete with voice prompts that’ll guide you through the simple steps to use it.

AEDs are widely installed in public locations in Singapore, with one for every HDB two blocks islandwide. You can also use SCDF’s app (iOS | Android) to look for a nearby AED.

2. Excessive bleeding from a gash

Day to day, papercuts may be our worst nemesis but they don’t come close to the nightmare of having a gaping, open wound. While most cuts and grazes can be fixed by slapping on a plaster or using one of these home reedies, excessive bleeding from a wound warrants a visit to the A&E. 

Emergency SOP: 

  1. Get someone to call for an ambulance
  2. Apply direct pressure on the wound with a clean bandage or cloth.
  3. If there is a foreign object wedged in flesh, do not remove it as you could potentially harm the surrounding nerves and blood vessels. Put extra cloth/bandage on either side of it to prevent the wound from moving instead.
  4. If the bandage or cloth is fully soaked with blood, do not remove and replace it as that might interfere with clotting. Just lay a second layer on top. 

In the event of a severed limb: Severed limbs can be “saved” and “replanted” back onto the body at the hospital if done within a few hours. An amputated finger, for example, can be reattached if it’s sealed in a clean bag with some air inside and placed in a tub of icy cold water.

3. Stroke

The scary thing about stroke is that it can happen to anyone; sometimes even when we’re asleep. Strokes can be caused by blockage of blood flow to the brain, causing brain cells to die by the minute. 

The severity of the stroke often depends on how quickly medical treatment is provided, so one of the most important things you can do is to spot symptoms as soon as possible, with the following “FAST” framework:

  • Facial weakness – sudden drooping of one side of the face
  • Arm weakness – numbness of arm or leg, typically only on one side of the body
  • Speech problems – sudden inability to speak clearly
  • Time – call for an ambulance ASAP and notify the operator of a suspected stroke

Emergency SOP: 

  1. Help the person lie down with head slightly elevated to aid blood flow 
  2. In the rare case that breathing stops, start CPR immediately

4. Choking


I know, we’re starting to sound like a verse out of Train’s 50 Ways To Say Goodbye, but it’s best to brace yourself for the worst, especially so for this next common dining mishap: choking. An elderly lady passed from ondeh ondeh going down the wrong pipe back in 2016, and hundreds of kids visit the ER for choking every year. 

You can tell if someone is choking if they’re grabbing at their throat, looking panicked and coughing, or trying to cough. Perform the following emergency SOPs as soon as possible: 

  1. Using the heel of your hand, deliver back blows by hitting the spot between the person’s shoulder blades 
  2. Repeat five times and check between blows to see if the obstruction is cleared
  3. If it doesn’t work, do the Heimlich manoeuvre: stand behind the person and lean him/her forward slightly. Make a fist with one hand and place it slightly over the navel, thumb knuckle facing in. With the other hand wrapped around the fist, deliver five thrusts inwards and upwards.
  4. Rotate between both methods and call an ambulance if the obstruction can’t be removed

If the person falls unconscious, deliver CPR – which would also help to clear the airway and dislodge the obstruction.

5. Seizure

Not to be mistaken for a stroke, a seizure is the less life-threatening of the two. Caused by a sudden surge of electrical activity in the brain, a seizure attack typically causes sudden jerking movements to a person’s arms and legs and stiffening of the rest of the body.

Contrary to popular belief, you’re not supposed to put an object into the person’s mouth during a seizure. You may get bitten, cause them to choke on the object or accidentally break the person’s teeth. Also do not attempt CPR on someone who’s having a stroke. 

Emergency SOP:

  1. Lay the person down in a recovery position
  2. Ensure there’s no hard or sharp edges where the person is at
  3. Time how long the seizure lasts
  4. Stay with the person until he/she becomes fully awake

Seizure attacks typically don’t require emergency medical attention unless you’re experiencing it for the first time. Also call 995 if the person is unable to respond even after he/she is awake, if there are two or more seizures within 30 minutes, or if the seizure lasts more than five minutes. These could be signs of a greater health threat.

6. Anaphylaxis (severe allergies)

While anaphylaxis may sound like a term out of a medical student’s textbook, it simply refers to allergy – specifically one of the most serious forms of it. Unlike mild allergies, anaphylaxis affects the respiratory or cardiovascular system, making the reaction potentially life-threatening. 

Common allergens that can trigger insect stings and bite, alongside food like peanut, seafood and eggs. And once it kicks in, we’re looking at a reactionary surge of chemicals from your immune system that can send you into shock. Symptoms include difficulty breathing, clammy skin and swelling of the tongue.

Emergency SOP:

  1. Call for an ambulance
  2. Look for an epinephrine auto injector such as an EpiPen and press it into the person’s outer thigh 
  3. Get rid of any possible triggers – such as a stinger still stuck in the skin
  4. Lie the person down and elevate his/her legs until help arrives 

7. Fractures

If you’re not careful, you can get a fracture doing virtually anything, from playing sports at school to your next outdoor hiking or cycling adventure. For general fractures, here’s the emergency SOP:

  1. Call for an ambulance
  2. Immobilise the limb by splinting it or securing it in place to prevent further damage
  3. Ice the wound to ease the pain until help arrives

Fractures are typically not life-threatening, unless it’s at the neck or back. If the person’s neck or back appear bent at an odd angle, avoid moving the person until first responders arrive as accidental damage to your spinal cord and nerves can cause paralysis or death. 

8. Burns


On to the reason why everyone says: don’t play with fire, kids. Burns happen most frequently in the kitchen at home, and can range from first-degree burns – a red and inflamed top layer of the skin – to third-degree burns, which refers to all the layers of skin being destroyed, appearing white or charred. 

Emergency SOP:

  1. Remove the heat source ASAP
  2. Take off any clothing in the burnt area, but don’t peel it off if it’s stuck to the skin
  3. Run cool – not iced or cold – water over the area for about 10 minutes
  4. Cover the burn with a clean bandage or gauze

Most burns are typically minor – but be sure to seek proper treatment if it’s an electrical burn, a burn that’s larger than the size of your palm or one with blisters or white/charred skin. Also do not soak third-degree burns in water as this can lead to infections.

9. Fainting

Fainting would be a cause for concern if it happens regularly, rather than that one time you decided to skip breakfast before a strenuous day. Usually, fainting is an isolated, non-emergency case, but you should call an ambulance if it is followed by an injury to the head or happens more than once in 24 hours.

Emergency SOP:

  1. Wait for the person to regain consciousness. If he/she doesn’t wake up in one minute, call the ambulance 
  2. Encourage the person to sit in a recovery position with head in between knees
  3. Loosen any tight clothing such as belts and offer some water
  4. After the person is fully awake, allow him/her to lie down and rest for at least 15 minutes
