➡️ Auscultation
Auscultation is the process of using a stethoscope to listen to the sounds within the lungs. When crackles are heard during auscultation, they are typically associated with the presence of fluid or secretions in the airways. Crackles can occur during both inspiration and expiration but are more common during the inspiratory phase of breathing.

➡️ Types
- Fine crackles
- Coarse crackles

➡️ Fine crackles indicate that fluid is in the smaller airways. They have a higher frequency and a shorter duration. These are often heard in patients with congestive heart failure (CHF) and pulmonary edema. They can be treated with diuretic medications, such as Lasix.

➡️ Coarse crackles are lower in pitch and longer in duration. They are caused by secretions in the larger airways. This type is often referred to as rhonchi, which is an abnormal breath sound that can be heard when air moves through larger airways that have accumulated mucus or secretions. Coarse crackles are typically heard during the expiratory phase of breathing. They can be treated with airway suctioning or bronchial hygiene therapy.

➡️ Other Types
Bilateral crackles – sounds that are heard in both lungs
Basal crackles – sounds that are heard in the base of a lung
Bibasal crackles – basal crackles that can be heard in both lungs

➡️ Causes
- Pulmonary edema
- Congestive heart failure (CHF)
- Pneumonia
- Atelectasis
- Pulmonary fibrosis
- Acute bronchitis
- Bronchiectasis
- Acute respiratory distress syndrome (ARDS)
- Interstitial lung disease

Crackles that do not clear after the patient coughs are usually associated with pulmonary edema or fluid in the alveoli due to congestive heart failure.
