You don't normally think of an asthma attack leading to something like this. No, and we? To understand asthma is a common lung condition but it can be potentially very serious in some cases fatal characterized by inflorida make and narrowing of the passageways in our lung that then can cause when someone is having an asthma attack wheezing, chest tightness, shortness of breath, a cough and can in some cases lower the oxygen levels in our blood which is a medical emergency. Can you explain how this happens? You know, we used to call it status asthmatic, that was the cause of death in this tragic cause but that's called a severe asthma exacerbation and that can happen when traditional treatments are not effective. This can last for hours and in some cases again it could be fatal once someone's oxygen levels drop below a certain point you get cardiac and brain involvement and unfortunately can be fatal and do have to remember still it's rare. Less than 200 teens and children die in this country every year but 6 million have asthma and even one is too many. Absolutely. Even one. So how do you know if you should go seek medical attention? That's really the key. You heard me say it before. We don't expect parents to make medical decisions other than trust their gut and their there are signs to look out for, number one if your child is in the middle of an asthma attack and need to stop talking midsentence to catch their breath that can be a sign. If they use their ab domhnall muscles to breathe, that's caused retraction and widingen their nostrils it's called nasal flaring and regardless of skin color if you see a dusky or bluish tint to the lips or nail beds that is an emergency. You need to get to an emergency room. All things we should keep in mind. I know you wanted to say something for veterans day. A shoutout to all our men and women in uniform but also my dad, U.S. Air force, I was born on an air force base. I am super proud of him today and every day.
