Can one have an asthma attack with a normal peak flow reading equal to 90% or higher along with normal o2/PR level? This seems to be an ongoing issue.

Can one have an asthma attack with a normal peak flow reading equal to 90% or higher along with normal o2/PR level? This seems to be an ongoing issue.

Unlikely asthma: You may probably have VCD, Vocal Cord Dysfunction, a condition that mimics asthma, but peak flow readings would be normal, there are some other subtle clinical differences too. Spirometry with inspiratory curve would be diagnistic / upper airways endoscopy (visualization of the vocal cords), treatment is different, you may want to see your asthma specialist and ENT specialist, good luck ...Read more

Can indigestion/acid reflux cause chest tightness & feeling like I cant take a deep breath? Peak flow normal not DX w asthma had normal EKG/stethoscop

Can indigestion/acid reflux cause chest tightness & feeling like I cant take a deep breath? Peak flow normal not DX w asthma had normal EKG/stethoscop

Very much so: I can tell you from both a professional and personal standpoint that acid reflux can be and is responsible for chest tightness, a sensation that a satisfying breath cannot be taken and is a very under diagnosed cause of cough and even sinus disease. It is very commonly mistaken for a heart attack or asthma and can significantly interfere with sleep and voice quality if acid hits vocal cords. ...Read more

Is a peak flow of 300 a reason to be concerned in a 58 year old 5 ft 7, normal weight?

Is a peak flow of 300 a reason to be concerned in a 58 year old 5 ft 7, normal weight?

Normal is 370: You are just barely in the green assuming your normal peak flow is 370. A number of assumptions. You probably have some underlying disorder like asthma or COPD causing your peak flow to be lower? Green means that you are ok, yellow range would be from 300 to 185 and below 185 is the red range. Red range, seek medical attention. Yellow range - you should have a plan with your regular physician. ...Read more

I'm a 52 year old female. 5'4 126 pounds. Had difficulty breathing in ED my peak flow was 350. And 375 after meds. Normal?

Peak flow (PF): PF of 350- 375 is adequate but not optimal should be 400-450. You should improve over the next few days and rise to normal levels. Take it easy do not exert yourself and take medication as directed. F/u /w/ pulmonary for asthma, environmental allergens. Also check cardiac function, Right ventricle/ pulmonary artery pressures

I have a wheeze when exhaling that won't go with inhalers. Peak flow is still normal, is this worrying? It's only a slight wheeze at the end of breath

Don't panic: It is most likely just a little residual pulmonary inflammation...It could be due to an environmental allergen. ..Like smoking, or being in or near a smoking area.
Best advice is to go see your family doc for a check-up...Especially if it is bothering you... ...Read more

Is peak flow always an indicator of how bad your asthma is? Mine is in normal range but my breathing feels shallow. Congestion maybe?

Is peak flow always an indicator of how bad your asthma is? Mine is in normal range but my breathing feels shallow. Congestion maybe?

Usually: Peak flow is a good indicator of how much "obstruction" there is in your large airways, caused by inflammation. Normal means your asthma is well-controlled. I would need to know what you mean by "shallow" breathing. Your doctor can listen to your lungs to make sure air is adequately penetrating all the lung fields, and to listen for wheezes, and to look for other causes of your symptoms. ...Read more

I purchased a peak flow meter to monitor my breathing before and after I exercise because I been having some coughing after running. Is it normal to have a reading of 350 at rest. What should I look for when exercising?

I purchased a peak flow meter to monitor my breathing before and after I exercise because I been having some coughing after running. Is it normal to have a reading of 350 at rest. What should I look for when exercising?

Prob. EIA: You almost surely have something called exercise induced asthma. You are 22. Your peak flow rate should be higher but make sure someone is watching you do it. You may be doing it incorrectly. If you indeed have EIA you can take albuterol inhaler just before running and it should stop the coughing and SOB. See your doc and learn about asthma and its management!! ...Read more

I would also recommend avoiding all triggers such as smoke and reviewing your asthma plan with your provider. ...Read more

Feel like not getting enough air through throat. Pulse ox, peak flow, and ekg all came back normal. What could this be? Lasted for 1 week.

Feel like not getting enough air through throat. Pulse ox, peak flow, and ekg all came back normal. What could this be? Lasted for 1 week.

Many causes: Tests that should be done besides the ones you list: d-dimer, BNP, CBC, TSH, BMP, CXR. If d-dimer positive, need chest CTA. If all are negative, methacholine challenge should be considered. If all are negative, and if it fits, consider stress as a cause as stress is, in fact, a well known cause but a diagnosis of exclusion. ...Read more

My peak flow reading is normal (around 400) but my chest/throat still feels tight. Should I take my inhaler or is this just anxiety?

Throat tight: If you have not taken anything would take 1- 2 puff of your inhaler. tea may help along with the inhaler as it has xanthines, a bronchodilator.. Also consider one Zyrtec (cetirizine) or benedryl. If not better in 15 minutes call 911 if you have already taken 2 puffs of the inahler call 911. f/u wtih urgent care /doc ...Read more

7 days have felt short of breath. EKG, peak flow, and pulse ox all normal. Chest feels tight and hard to get a deep satisfying breath. Is this anxiety?

Short of breath: Have you had upper respiratory infection recently? Any injury to chest wall? I would certainly not rule out anxiety but usually this does not cause pain with deep breath. I would want to see a chest X-ray done too. ...Read more

17 year old male ekg, blood work, peak flow meter, chest X-ray, echo, all normal still have chest discomfort at times short breath, BP 117/80?

Asthma.: It's great that all your testing has been fine, but you may need more specific testing to elucidate the cause of your symptoms. For example, for asthma the peak flow in your baseline state may simply not be accurate enough. The best test for this would be a pulmonary function test with a methacholine challenge. And for the heart (unlikely but possible), stress test better than 2D Echo. ...Read more
