Wheezing is the shrill whistle or coarse rattle you hear when your airway is partially blocked. It might be blocked because of an allergic reaction, a cold, bronchitis or allergies. Wheezing is also a symptom of asthma, pneumonia, heart failure and more.
Crackling (Rales)
You're more likely to have them when you breathe in, but they can happen when you breathe out, too. You can have fine crackles, which are shorter and higher in pitch, or coarse crackles, which are lower. Either can be a sign that there's fluid in your air sacs.
For example, crackles that occur late in the inspiratory phase (when a person inhales) may indicate heart failure or pneumonia. A doctor may also ask for: chest X-rays. a sputum sample to test for infection.
Heart Failure
Crackles will be detected higher in the chest with worsening severity of HF. Crackles may be absent in patients with chronic HF even in the setting of elevated pulmonary capillary wedge pressure. Also, crackles may be difficult to hear in patients with emphysema or other coexisting pulmonary diseases.
Crackles occur as a result of small airways suddenly snapping open. They may indicate that a person's lungs have fluid inside them or are not inflating correctly. Causes of crackling include: pneumonia.
Coughing or deep inspiration may change the quality of coarse crackles, such as those associated with underlying alveolar or airway disease, but the crackles rarely disappear entirely. Expiratory crackles are much less frequent than inspiratory crackles and are often seen in obstructive lung disease.

This typically lasts no more than a few hours, but each patient is different and it can continue for as long as 24-48 hours. While the sound is difficult for family members to hear, it does not cause the patient pain or distress.
Your doctor will listen to your lungs with a stethoscope. If you have pneumonia, your lungs may make crackling, bubbling, and rumbling sounds when you inhale.
Sometimes when you cough, you can bring up mucus, also called phlegm or sputum. When that happens, doctors call it a “wet” or "productive" cough. When you have one, it may sound and feel like something is rattling around in your lungs. This kind of cough may happen because of an infection or another health condition.
Late inspiratory crackles may indicate pneumonia, CHF, or atelectasis, a complete or partial collapse of a lung or lobe of a lung. Crackles can also be considered fine (high-pitched) or course (louder and lower in pitch).
Acute bronchitis can cause a phlegm-producing cough, fatigue, a sore throat, and a wheezing sound while breathing.
Crackles are often associated with inflammation or infection of the small bronchi, bronchioles, and alveoli. Crackles that do not clear after a cough may indicate pulmonary edema or fluid in the alveoli due to heart failure, pulmonary fibrosis, or acute respiratory distress syndrome.
Bacterial pneumonia is more serious and often results in a gurgling sound when breathing and mucus or phlegm when coughing. If you are experiencing a cough and are concerned that it may be pneumonia, reach out to your doctor.
Chest infections are common, especially after a cold or flu during autumn and winter. Although most are mild and get better on their own, some can be serious or even life-threatening.
Fine crackles could suggest an interstitial process; e.g pulmonary fibrosis, congestive heart failure. Coarse crackles are louder, more low pitched and longer lasting. They sound like the separation of Velcro. Coarse crackles could suggest an airway disease, chronic bronchitis.
Breath sounds will reveal bilateral rhonchi or crackles. These will usually be in the lung bases. Unilateral crackles are not indicative of CHF but suggest other diseases such as pneumonia.
Although the lung sounds of COVID-19 pneumonia have not been previously described elsewhere, severe cases under mechanical ventilation occasionally have coarse crackles at their acute exaggerated respiratory phase, while most cases with mild to moderate COVID-19 pneumonia usually seem to have subtle fine crackles or no ...
The condition also causes some distinct sounds ranging from wheezing to cracking when you breathe, which isn't surprising since COPD is an umbrella term for a group of lung diseases (including chronic bronchitis and emphysema) that obstruct the lung's airways and make breathing difficult.
