WATCH: World Asthma Day: Stark video shows what it feels like to have an attack
Only 7 per cent of asthmatics know all the symptoms of an asthma attack, according to the Asthma Society of Ireland (ASI).
One person dies every week in Ireland as a result of their asthma.
But 90pc of these deaths are preventable, the ASI says.
The CEO of the Asthma Society of Ireland, Sarah O’Connor said: “It is troubling to think that so few asthmatics know all the symptoms of an asthma attack, placing them at huge risk of a serious attack which can be fatal."
"Therefore, it is vital that all asthmatics and their carers learn the symptoms of an asthma attack and the 5 Step Rule so that they are fully prepared. It really could be the difference between life and death."
The five step rule:
1. Stay calm. Sit up straight - do not lie down.
2. Take slow steady breaths.
3. Take one puff of your reliever inhaler (usually blue) every minute.
Use a spacer if available.
People over 6 years can take up to 10 puffs in 10 minutes.
Children under 6 can take up to 6 puffs in 10 minutes.
4. Call 112 or 999 if your symptoms do not improve after 10 minutes.
5. Repeat step 3 if an ambulance has not arrived in 10 minutes.
