Can you have pneumonia w/ the only symptom being intermittent chest pain? Had flu/prolonged sinusitis. Have asthma. Peak flows are really good (500+)

Can you have pneumonia w/ the only symptom being intermittent chest pain? Had flu/prolonged sinusitis. Have asthma. Peak flows are really good (500+)

Unlikely: If you have pneumonia, you would likely have a cough, fever, or problem breathing. At your age, heart disease is not a strong suspect unless you are diabetic. Need to consult your doctor re. The chest pain- I could have given you a better answer if you had specified the location of the location, duration, triggers, or character of the chest pain. ...Read more

Currently on oral steroids for Asthma but still peak flow is around 350 and drops to around 260, soon as I got to work (clothing store) it starts off and continues all day and worked there 4 years now?

Occupational asthma?: Great that you are tracking with peak flow monitoring. Continue this mornings, evenings, at work and also on days off. Document it. If you are still recovering from a flare up such as after a cold then it could be any kind of dust, smoke or fumes including perfumes and off-gassing from new clothing that's irritating it. This may resolve once the flare is over. Continue inhaled steroids. ...Read more

Asthma attack. Will peak flow reduce if the person has pulmonary fibrosis?

Asthma attack. Will peak flow reduce if the person has pulmonary fibrosis?

Usually: If there is reversible air flow blockage, that would show as a decrease in peak flow that reverses when the attack is cleared. The difference between a usual and reduced peak flow will be lower in pulmonary fibrosis since the volumes of air are decreased overall. ...Read more

Steroids: People with chronic asthma or COPD if they need steroid should not be withheld as it is lifesaving. We do have to protect the bones as we want to avoid most of all spinal fractures. We can give certain things like calcitonin or bisphosphonates if needed. Your doctor and you can make that decision when you discuss your problem. ...Read more

Have adult onset asthma. Allergies make worse. Peak flow test was 38/58. Started qvar. Can I take long time? What long term use side effects? Age 57

Have adult onset asthma. Allergies make worse. Peak flow test was 38/58. Started qvar. Can I take long time? What long term use side effects? Age 57

Mgt: Your peak flow and continued symptoms indicate that your asthma control is not good. I would suggest continuing the QVAR and taking the asthma control test online at regular intervals. A HEPA filter unit at home can help to reduce indoor allergens. Avoiding smoke and other triggers is important in your mgt.

How to bring up peak flow in someone with asthma?

How to bring up peak flow in someone with asthma?

Asthma control: Peak flow will improve when your asthma is controlled. Remember if your asthma symptoms are persistent, you need to take a controller medication every day even though you do well. This way, your asthma symptoms are not likely to recur and your peak flow will improve. A controller is usually an inhaled corticosteroid. ...Read more

Could I have good peak flows during an asthma flair?

Could I have good peak flows during an asthma flair?

No: asthma flare means that you have tightened airways, no way your peak flows would be normal, you might be hyperventilating, gives the same feeling as having an asthma in the beginning, good that you use your peak flow for assessment ...Read more

Chart says nrml peak flow for womn my age is 422 so a peak flow of 390 not so diffrnt my norm is 600 is it different if I blow 390? In terms of asthma

Chart says nrml peak flow for womn my age is 422 so a peak flow of 390 not so diffrnt my norm is 600 is it different if I blow 390? In terms of asthma

Albuterol?: A lot depends on if the peak flow measurements are all done on the same machine or device. A peak flow of 600 on a hand held portable plastic device may be equal to a different number on an office spirometer. If you use the same device and your level falls from 600 to 390 then that is significant and you probably should be using albuterol, your quick reliever. ...Read more

Treatment plan: An essential part of asthma treatment is your own involvement with your care. If you and your physician have decided you need to monitor your breathing daily, you should have one. If you don't know your plan, you can't follow it, so talk to your physician. ...Read more

See your doctor: I would recommend seeing your doctor regarding this issue--peak flow meters, while sometimes helpful, can sometimes be manipulated by other factors. Therefore, peak flow may not be the best indicator of asthma control. ...Read more

How big a drop in peak flow is indicative of asthma? Highest is 720 but becomes 660 - 610 without Ventolin. Can Ventolin improve PF in healthy people?

How big a drop in peak flow is indicative of asthma? Highest is 720 but becomes 660 - 610 without Ventolin. Can Ventolin improve PF in healthy people?

Numbers and Symptoms: In a patient with known asthma, we generally understand an exacerbation to be in the 75% drop range on peak flow. Your numbers reflect a 92% drop. No, ventolin does not improve peak flow in healthy people. Do you have shortness of breath? You take flonase, which is for allergic rhinitis? Are you interested in athletic performance? A Prime Consult may help further the understanding you seek! ...Read more

My peak flow is normal but the doctor says I have asthma. How?

Reason....: When you are not having an exacerbation of asthma, your peak flow will be entirely normal because asthma consists of episodic obstruction. During an acute exacerbation, your peak flow will drop but between episodes, it will be normal. ...Read more

I have very severe asthma and I cannot get wheezing and coughing under control what should I do peak flow is 60 everything else ok?

I have very severe asthma and I cannot get wheezing and coughing under control what should I do peak flow is 60 everything else ok?

Everything else ok?: What does "everything else ok" mean? It sounds like everything else should not be ok. That means one should see a doctor now. Today is sunday, so if one's doctor is not available to help, the place to go would be the emergency room. If symptoms are worrisome, an ambulance ride is the safest way to go, instead of having a friend or relative drive (unless an ambulance is not available either). ...Read more

Can benzos reduce scores on peak flow meter tests? Had spirometery test which were lower but did not change with asthma medication. Thanks

Can benzos reduce scores on peak flow meter tests? Had spirometery test which were lower but did not change with asthma medication. Thanks

What exactly?: What type of benzo you are talking about? PFR is mostly used for follow-up and not for diagnostic purpose since it is too effort-dependent. Thus it is not surprising that its findings differ from spirometry which is used for diagnosis as well as follow-up. A significant number of asthma patients do not show PFT improvement from bronchodilator and thus this alone does not rule out asthma. ...Read more

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

Escalate treatment: Need to move past just using rescue inhaler to inhaled corticosteroids. You may feel like you are doing okay with only evening symptoms, but in the long term you may still be damaging your lungs and may develop copd. Consult your doctor for additional medication. ...Read more

How long does advair take to be fully working? Is an increase in peak flow from 350 to 450 or fev1 from 2.52 to 2.91 indicative of advair working? Are those #'s ok? Asthma, 33yo female, 64in, 185 lbs.

How long does advair take to be fully working? Is an increase in peak flow from 350 to 450 or fev1 from 2.52 to 2.91 indicative of advair working? Are those #'s ok? Asthma, 33yo female, 64in, 185 lbs.

Variable: Depends on the underlying disease process, and individual factors. Some people get near immediate benefits (within 48 hours) while others take a week or slightly more. Those numbers show improvement, but how long have you been on the advair? And at what dose? Have your symptoms improved? If so, just follow up with your physician at your next appointment. Good luck! ...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 cough when take a deep breath and exhale. What causes? I have asthma on meds even when peak flow ok. Also diaphram spasms 2+xs per wk, not dehydrate

I cough when take a deep breath and exhale. What causes? I have asthma on meds even when peak flow ok. Also diaphram spasms 2+xs per wk, not dehydrate

Well: You need a pft to measure your lung function since pfr is often not a reliable gauge on the severity of your asthma. I am concerned that you are still having symptoms despite 2 courses of steroid. Have you seen an allergist? I note that you are not on any inhaled steroid and using bronchodilator alone regularly may actually worsen your asthma. ...Read more

What might cause a person with asthma to have shortness of breath but a consistently high peak flow (750+), and all of their cardio tests checked out fine?

Anxiety: In my experience, when someone has a subjective feeling of shortness of breath, palpitations, chest tightness etc., but all the objective measures are checking out ok, what you may actually be dealing with is an anxiety problem. But first you rule out the physical stuff. ...Read more

I have been using clenil modulite 100 mcg a few months a year for seasonal mild Asthma. And sabutamol 100mcg 2x a week or when needed but not often. I blew a Peak flow of 470 GP said last time was 480 so changed me to Fostair100/6 What's difference?

I have been using clenil modulite 100 mcg a few months a year for seasonal mild Asthma. And sabutamol 100mcg 2x a week or when needed but not often. I blew a Peak flow of 470 GP said last time was 480 so changed me to Fostair100/6 What's difference?

Asthma inhalers: Clenil modulite 100 vs fostair 100/6. Both contain the same amount of ICS, beclomethasone, fostair in addition has long acting bronchodilator, formoterol, vs salbutamol, short acting, that you use as needed. Your peak flow readings look stable, and your symptoms too seem controlled. This is a judgment call by your doctor, however, you are using propranolol for migraine, that needs to be revised ...Read more

My peak flow is 50 lower than usual, I feel breathless and have a wheeze is this serious asthma I'm panicking. How low does pf go before its serious?

It depends: Any peak flow results that are below 80% of your "personal best" are grounds for concern and need immediate action. If any readings ever dip to 50% or less (your "red" zone), you need to go to the er immediately. You should follow your own "action plan" (rescue inhaler, then inhaled or oral steroids). If you are very breathless after the inhaler or your lips are bluish, go to the er asap. ...Read more

I have asthma, but 2 hrs after using my albuterol inhaler it feels like I need to use it again. Is it anxiety? Sp02 above 97% and peak flow in green.

Need maintenance: It sounds like you are using your inhaler a lot. Would definitely recommend that you discuss with your doc. You would definitely benefit from a maintenance inhaler, if you are not on one, some time short steroid tapers are needed. Workup is sometimes also needed for conditions that may exacerbate your asthma. Do not postpone looking for help.

Had cough a month went to hospital I blew in a peak flow meter then got a neb treatment and tolled me I had asthma how would I know for sure if I do?

Diagnosis...: By definition, asthma is recurrent episodes of bronchospasm so you need more than one episode for the diagnosis to be made. You can also have pulmonary function testing to determine if you have any bronchospasm either at rest or with provocation testing. See your doctor so you can be diagnosed and treated, if you have asthma. ...Read more
