What actions should you take if someone faints? Knowing what to do in response to this common inquiry might be challenging. In this blog post, we’ll go over the actions you should take in an emergency. Additionally, we’ll offer some advice on how to stop someone from fainting in the first place.
What is Fainting?
Fainting is a temporary loss of consciousness, otherwise called syncope. It is generally caused by a temporary reduction in the blood supply to the brain. Before fainting, the casualty may feel lightheaded, nauseous, or dizzy and appear pale and clammy.
What is Hypotension?
Hypotension, often known as low blood pressure, is a condition marked by blood pressure lower than normal for the person.
What is Orthostatic Hypotension?
Orthostatic Hypotension causes a sharp drop in blood pressure while getting out of a lying or sitting position. This may make you feel lightheaded and dizzy, which is risky if you’re driving or working on other duties that require concentration. Orthostatic hypotension can be uncomfortable, but it is typically not harmful and can be managed with medicine or a lifestyle change.
Causes of a Fainting
There are identified causes of fainting in people, and sometimes the explanation is not immediately apparent. Dietary factors such as dehydration or low blood sugar can contribute to fainting. Low blood pressure, oxygen insufficiency, blood loss, head injuries, and heat stroke are a few other physiologically based potential reasons. The pulse of a fainting person will slow down, but it will typically pick up and return to normal within minutes. A more serious situation could arise if a person who has fainted remains unresponsive after a few minutes.
No matter what caused someone to pass out, giving them the same first aid treatment is best.
How Do the Causes of Fainting Happen?
When your body doesn’t have enough fluids, dehydration occurs. Dehydration can range from mild to moderate; if untreated immediately, it can become severe. Losing too much fluid leads to low blood pressure, and your body could lead to fainting.
Low Blood Sugar
Hypoglycemia is when your blood sugar (glucose) level is lower than the standard range. For a normal person without diabetes, normal blood sugar level is 70–99 milligrams per deciliter (mg/dL) (3.9–5.5 mmol/L). Hypoglycemic patients have a blood sugar level below 70 milligrams per deciliter (mg/dL) or 3.9 millimoles per litre (mmol/L).
According to Harvard Health Publishing, when your blood sugar is low, your brain tries to conserve as much energy as possible, which may cause you to feel dizzy and could cause fainting.
Low Blood Pressure
Hypotension or low blood pressure happens when the pressure circulating in the body is lower than normal. The low blood pressure reading is less than 90/60mmHg. Low blood pressure could lead to fainting when insufficient blood supply in the lungs, heart, and the rest of the body.
A vasovagal attack happens when there is increased blood loss and makes the blood pressure drop, reducing the circulation to the brain and causing fainting.
What is Hypovolemic shock?
Hypovolemia, on the other hand, occurs when the body’s blood volume falls too low. This is when a person has lost at least 15% of their blood volume.
When levels are thus low, a variety of symptoms are frequently experienced by people. Dizziness, muscle cramps, weariness, and darker-coloured urine are some symptoms. Shortness of breath, profuse perspiration and unconsciousness are more severe symptoms.
Heatstroke is a severe heat-related illness. This is a medical emergency as it may lead to unconsciousness and death. Any organ in the body could be impacted. Usually, it happens when the body temperature is 40 degrees or higher. The decreased blood supply causes dizziness and fainting brought on by heat to the brain.
Management of Fainting
- If a casualty is lightheaded and appears near fainting, the best thing to do is lie down on their back and raise their legs, increasing the blood supply to the brain.
- If the casualty refuses to lie down, keep close to the casualty in case they collapse. Remember to protect your back – if the casualty is falling, do not attempt to keep them upright, but guide them gently down onto the ground.
- Once on the ground, they can be placed in the recovery position.
- If they lose consciousness, follow DRSABCD.
Fainting usually lasts only a few seconds to a minute or two, and the casualty may even have a slight seizure.
- Proper placement into the recovery position will assist recovery. Once conscious, encourage the casualty to lie down until they feel better, then very gradually move back into an upright position to reduce the risk of fainting again.
