Hi @Walkingandtalking , I'm a respiratory nurse. Steroids - yes, all 8 in one go once a day. This will equate to 40mg probably, which should help to settle any inflammation in the airways within a couple of days. Inflammation can cause shortness of breath and wheezing.
As for peak flow - take best of 3 readings morning and evening. Sit up straight, breathe all the way out, deep breath in, and sharp hard blow. Best of 3. You'll probably notice it rapidly increasing in the next few days as the steroids kick in so it's important to get a few readings in now before that happened so they can see a baseline. Mark on the chart when the steroids were started. 150 is low, but this is expected if true asthma as the inflammation in the lungs massively restricts airflow. With peak flow, they are looking for confirmation of diagnosis which isn't just from 1 or 2 readings. It comes in the form of seeing improvement in morning and evening readings after the use of steroids. Either tablet or inhaled steroids. Now because she will be going straight from tablet to inhaled steroids, there may not be a massive amount of data for them to work on, but still do the readings as it will help to confirm things. Normally with asthma, we are quite a difference, and also a difference between morning and evenings.
Inhalers - RIGHTBREATHE website is fantastic for inhaler technique (and peak flow) so check that out. Technique is important because there is no point taking if not done properly, as the drug will just sit in the mouth rather than getting into the lungs.
Hoping the GP have a spacer with the inhalers?? Blue inhaler to be used when required. Usually takes a couple of mins to start working, at its best at 20 mins. If severe asthma, she may need more than just 2 puffs to make a difference. If not using a spacer, I'd suggest buying one from the chemist ASAP. Or getting GP to do a script. With a leak flow of 150, it might be hard to get the drug to the smaller airways which is probably why she didn't feel much difference.
Brown inhaler - probably 2 puffs twice a day? She won't feel much of a difference with this one, but it's very important to keep it up as this is the thing that will actually treat the asthma. It usually takes 2 ish weeks to get into the system but because she's got tablet steroids, by the time she ends them, the inhaler will take over.
Really hope this helps, look at the website. Let me know if you need any more info. And worth feeding back to the GP surgery that patients that are given inhalers for the first time need better explanations! X
