Snap, Crackle, Pop! Lung Sounds
RATE

The Holidays are always a busy time and with a very festive week came Siberian cold temperatures and the dreaded return of my “friend” the cough and a wheeze. It all began with what I thought was exposure to a trigger that I had not been expecting, it seemed to throw my asthma in to a tailspin. I was mostly sure that this may have been induced by coming into contact with wrapping paper that was being burned in a fireplace, which of course produce a concerning smoke. Yuck and yikes!

I activated my asthma action plan and began working, starting with a SABA rescue meds and waiting for responses. Have I mentioned that I have a knack for getting sick or having a respiratory situation during the holidays and long weekends? Unfortunately, connecting with non-emergency respiratory care during the holiday involves paging your doc. I only like to page in case of emergencies, etc. The worst things to do would be to misuse that option. My health care system is not so enthusiastic with misusing paging privileges.

When the the Dr. said “crackles”

I had a follow-up booked a few days later so I was not as concerned about it but then came the physical exam. My wheeze seemed to have disappeared. I know that not everyone wheezes, but I am generally a wheezer. I have been really well controlled lately so, it caught me off guard to even be wheezing. My wheeze was mostly gone by the time that my follow up rolled around. I swear it is always that way. The doctor heard some crackles, crackles….what are crackles, what does this mean?

“Crackles are discontinuous, explosive, “popping” sounds that originate within the airways.1 The sounds are made when the airways suddenly open and the pressure on either side of the obstruction equilibrates in distinct vibration in the airway wall.1

The airway obstruction is thought to be due secretions in the airway lumen or by collapse caused by the pressure caused by inflammation or edema in neighboring tissue. Crackle can often be heard more on inspiration than expiration, they are important because they can indicate fluid within the airways or inflammation.1 In my case, the guilty cause was thought to be mucous in the way causing obstruction. The best thing I can do is clear it, which means increasing my daily session of mucus clearing with my Oscillating Positive Expiratory Pressure (OPEP) device. It is oh, so glamorous! Honestly, I do feel better after the clearing but I do wish that sputum/mucous was not always so present in my world.

Wheezes, these are high pitched sounds that originate from the narrow airways. The wheezes occur as a result of air struggling to get through. In some cases, the sound may be so high that it can be heard without a stethoscope.

Rales these sounds can be heard as rattling or bubbling.

Stridor is similar to wheezes, but unlike wheezes, these sounds are caused by the narrowing of the trachea.

Rhonchi, these crackles sound like light or heavy snoring. They are caused by the blocking of the airway that keeps breath from flowing smoothly in and out of the lungs.2

What lung sounds have you experienced? I am convinced that one day I will make a soundtrack of my lungs. I would love to hear about your experiences.
