Dr. Rich - Question about "Lung Crackles"
About This Forum:

Pulmonary hypertension is a condition associated with high blood pressure in the arteries that connect your heart with your lungs. It is a serious condition for which there are many emerging treatments but no definite cure. In this disease, the blood vessels that carry oxygen-poor blood from your heart to your lungs become hard and narrow, which causes your heart to work harder to pump the blood. This forum is a place to ask questions about Pulmonary Hypertension. Some examples are: What caused me to get pulmonary hypertension? How is pulmonary hypertension diagnosed? What treatment options are available?

IMPORTANT!! If you have a question that requires immediate medical attention, or if you think you may have an emergency situation, please call your doctor or 911 IMMEDIATELY!

Dr. Rich - Question about "Lung Crackles"

Dr. Rich,

My question is this:

Can bibasilar crackles be heard by a person, from their mouth or are these only picked up by stethescope?

Thanks so much.

Hello and welcome to the forum.

If a person were to have significant amounts of fluid in their lungs, one could likely here "crackles" even without a stethoscope.  Alternatively, somtimes what is more apparent is the presence of "wheezing" which is often found in heart failure (even though it tends to be more associated with asthma).

However, a stethoscope will not only pick up the "loud" crackles but will also be able to hear the more subtle (yet important sounds) that the human ear would be unable to detect.

Hope that helps.

Dr. Rich thank you for answering.

I have on occassion heard crackles from my mouth but more often mornings upon waking. I've had two chest xrays over a year spance -- the last one being only 3 months ago and my heart is normal size. I've also had two BNP blood tests; the first one showing a result of "4" and the second one showing a result of "16" but still far below the "100" cut off limit that would indicate any heart stretching.

I lean toward my crackles being possibly from asthmatic bronchitis or possibly chronic bronchitis but being a non-smoker, mine is probably a result of my years of badly conrolled GERD.

I will be getting a spirometry this week and this should possibly tell me more.

Thanks again.
