8th April 2019 Friday Resus Ready First Aid Trivia
How do you treat a blood nose?
Having a blood nose is somthing that we have all experienced at some point in our life. So for this weeks trivia question, my question to you is this…
How do you treat a blood nose?
Option 1: Pinch the bridge of the nose and tilt the head back
Option 2: Pinch the bridge of the nose and tilt the head forward
Results from the facebook poll are:
- Option 1 – Nose pinch and head back 27% 27%
- Option 2 – Nose pinch and head forward 73% 73%
If you answered Option 2 – Nose pinch and head forward then you would be correct.
Ever wonder why some people always get nose bleeds on aeroplanes or on hot days?
The nose contains a large amount of tiny blood vessels. Nose bleeds can occur for many reasons. Excluding traumatic reasons, nose bleeds occur in large part due to the drying out of nasal membranes (lining of inside your nose) which can be from breathing in dry air either from airconditioned air or staying in an area with low humidity. Traumatic reasons could be from excessive sneezing, external force to the nose (like being hit by an object) or from causing internal trauma from picking your nose.
Why do some people get a blood nose on a hot day or after excersising?
On hot days or after excersice our blood vessels near the surface of our skin become dilated (large and fat to allow more blood to pass through them) The closer the blood is to the surface the cooler it gets, by forcing more blood nearer to the surface the body can cool down faster decreasing the core body temperature. This also gives the skin the flushed or reddened appearance.
The blood vessels in the nose are very delicate and so when they dilate they can sometimes break, causing the blood nose.
So what part of your nose do you pinch if you have a blood nose?
As an activity, pinch the top of your nose (the bridge part of your nose between your eyes), now feel your way down your nose until you feel the spot where the bone part stops and you can just feel the soft cartlidge (squishy) part of the nose. THAT is the spot you pinch. From this spot you can effectively put pressure on the nasal passage to stop blood from traveling through.
Head back or head forward?
If we tilt our head back, we are expecting the blood to travel back down our throat and into our stomach. As a rule of thumb our stomach does not like having blood in it. It sees blood and thinks there is a problem and wants to get rid of it the easiest way it knows how – by emptying the contents through spewing. Not the most ideal situation to be in when you are already treating bleeding from the nose and now you have gastric contents coming up into the mouth and nasal passage.
Instead, the Australian Resuscitation Council (ARC) reccommends pinching both sides the soft part of the nose below the bony bridge and tilting the head forward. Any excess blood coming from the nose will drip out and also has the added benifit of indicating when the bleeding is decreasing. A tissue or cloth can be used to catch any blood leaving the nose. Any blood in the mouth should be spat out rather than swallowing.
How long do we pinch the nose for?
The casualty should remain seated at total rest for at least 10 minutes. An ice pack can be placed near the bridge of the nose to help constrict (tighten) the blood vessels in the nose and for comfort. On hot days or after excersise, the pressure should be kept on for at least 20 minutes. If pressure is released to check if bleeding is continuing then the 20 minute timer starts again.
If the bleeding has not stopped after 20 minutes of continuous pressure you should seek medical assistance.
