Nosebleeds reassurance please

[Whatsmydoggy]

A couple of weeks ago my 3 year old had a nose bleed out of the blue. Now my almost 9 year old has just woke me up as she's had a nose bleed. I'm lying wide awake too scared to go back to sleep as I remember reading before that this can be a sign of carbon monoxide poisoning so had a look on Google which confirms this is true. I know nose bleeds are common in children but neither of mine have had one up until now. I have a carbon monoxide detector in the cupboard where the boiler is and one in the kitchen near the gas cooker. Am I being over paranoid or would anyone else be concerned about this?

Hi, my advice would be to firstly to ensure you sleep with an opened window until you are sure. Check your two CO alarms (great that you have them, you sound pretty switched on about the dangers) and their batteries. If either of them have digital screens that show a reading for ppm of CO (parts per million of carbon monoxide) then make a note of it in case you need to tell a medical professional - long exposure to even a small amount can be harmful. Check your appliances next - do they have a strong blue flame (good) or weaker yellow one (dangerous), do they have any signs of dark patches on nearby surfaces, such as the walls around the boiler? All these can be signs of an appliance not combusting properly. If you have had any drowsiness, nausea, headaches, wooziness etc then please go for a checkup and definitely get a Gas Safe Registered engineer that has the correct qualifications shown on his Gas Safe card for your appliances to come and service them, including doing a Carbon Monoxide emissions test (not always done as standard, but should be no problem at all for a reputable tradesman). If your GP tests you for CO and it comes out low or negative, be aware that low levels can clear from the system quite quickly once you are breathing healthier air, so it may not be conclusive - get the engineer to check the emissions, that's the only true piece of mind. I hope all that helps.
