Crackles in Lungs Meaning, Crackling Lung Sound When Lying Down Causes, Treatment

What is crackling sound in lungs?

Have you noticed crackling in lungs when you are breathing? It is normal to get worried when you notice a crackling or wheezing sound coming from your lungs when inhaling or exhaling.

However, at times, you will find that these are just but normal sounds made by the lungs when excess mucus has gathered in them, or when you have an underlying medical condition. The crackling in lungs could be a symptom of many varying conditions, some of which are serious, while others are not.

The causative conditions have been known to vary in two main ways including:

• Unexpected asthma attacks
• Lung cancer

The treatments prescribed by the physician will often vary depending on what has caused this condition to appear. When you know about the different factors that can cause crackling in lungs sounds, you can be in a good position to put in place the right intervention measures.

You need to ensure that you check the symptoms accompanying each condition before you can start treatment, as this will help provide you with a better clue on what is affecting you.

What causes crackling in lungs?

Even if the cracking in lungs has become normal for you, there is a need to check out all the other accompanying symptoms. Checking the symptoms accompanying the sound will act to provide you with a good clue on what is happening in your body. You will also get to know whether the sounds are being caused by a serious condition, or by a minor one.

The causes include:

1. Pneumonia

Pneumonia is characterized by the inflammation of the air sac in one or both lungs. In some cases, pneumonia can be fatal, more so when the patient does not seek medical help. It is recommended that you seek medical attention from your GP the moment you notice the crackling sound when inhaling or exhaling.

• Fever
• Headaches
• Shortness of breath
• Muscle pains
• Chest pains
• Fatigue
• Perspiration

Given that the lung crackles rarely do appear on their own, and due to the fact that you cannot hear your lungs very well, there is a need to pay attention to the other symptoms that accompany this sound, such as having a dry cough. It is important to understand that dry coughs are very different from wet ones, as they both indicate the presence of a different problem in the body.

• raise collapsed lungs

After a chest surgery, you may hear four different types of crackling in lungs sounds.

The sounds include:

Wheezes

The wheezing sounds are high pitched, and will be produced by an airway that has become extremely narrowed. The air will produce the wheezing sounds as it is struggling to get through the airway. When the airway has become too narrow, you may be able to hear these sounds without having to rely on a stethoscope to listen to your breathing.

Rales

They can best be described as a type of bubbling or rattling sound. In some cases, the crackling sounds may be described as dry or fine, which means that the sounds are light, and they are not accompanied by any moist sounds when you are breathing.

Stridor

Stridor noises are very similar to the wheezing sounds, in that they are also caused by airways that are blocked, or which have become too narrow. When the stridor noises are being produced, it will mean that your problem lies in the trachea region.

Rhonchi

It has often been described as being similar to snoring (light and heavy snoring). It is a sound, which comes about when there is a blockage in your airway. The blockage will make it difficult for you to breathe smoothly, meaning that there will not be a smooth flow of air in and out of the lungs.

4. Asthma

The condition has been to take place when the airways become swollen, narrow, and begin producing excess mucus. When this is taking place, breathing will become difficult, and this will lead to the following:

• crackling in lungs
• wheezing
• shortness of breath

For some people, asthma has been known to be a small irritant, but in other cases, it is a major problem, and this may make it impossible for such people to go about with their day to day activities. This is often the case with the life-threatening asthma attacks.

5. Cold and flu

Cold and flu are some of the causes of crackling in lungs sounds. When a person has a cold or flu, the respiratory tract linings will start to produce lots of mucus. The mucus is meant to lubricate the respiratory tract lining, which has been known to dry out due to the movement o f air in and out of the nasal passages.

However, you will find that in certain conditions, these mucous membranes may produce excess mucus, which may start to sink lower inside your lungs. When it sinks lower, it will lead to the production of the crackling sounds. If the mucus is not expelled outwards through your mouth, it may settle in the lungs, thereby blocking the passageways or diminishing your ability to breath properly, resulting in wheezing.

6. Bronchitis

It is a condition where the bronchial tubes lining become inflamed. On occurrence, bronchitis can either be acute or chronic.

• Acute bronchitis is the more common of the two, and the condition will in many cases develop when a person has a cold, or an infection of the respiratory tract system.
• Chronic bronchitis, though not common is considered the most severe. A person with chronic bronchitis will experience constant irritation and inflammation of their bronchial tubes lining. Smokers are advised to do away with this habit as it may make their symptoms severe.

7. Pulmonary edema

Pulmonary edema occurs when the air sacs present in the lungs are filled with excess liquids. The fluid buildup may be brought about by;

• severe infection
• trauma
• heart failure
• Taking certain medications.

Pulmonary edema symptoms include:

• coughing blood
• restlessness
• nasal flaring
• pale skin

The condition may also be accompanied by confusion, crackling sounds when exhaling, anxiety, as well as breathing difficulties.

8. Congestive heart failure

The condition arises when your heart becomes damaged by;

• an infection
• a prior heart attack
• physical injury
• genetic conditions
• Side effects arising from the use of certain medications.

When your heart fails, it could lead to the buildup of fluids in the lungs, through a condition that is known as pulmonary edema.

Lung cancer is one of the chest infections that can lead to crackling in lungs. The cancer will often begin in the chest area before progressing to other parts of the chest cavity. Habitual smokers have the highest risk of developing this condition.

On occurrence, lung cancer is characterized by the growth of unrestrained cells in all the lung tissues. Some of the symptoms exhibited by people with lung cancer include;

• weight loss
• shortness of breath
• coughing in some cases accompanied by blood

Crackling in lungs when lying down

The lung crackles are caused by a condition known as postnasal drip. The sounds can be heard when a person is attempting to lying down, but not when they are sitting up.

During postnasal drip, what will happen is that all the excess mucus present in your nose will find its way down your throat, and all the way into your airway. Once in the airway, they will start producing lung crackles that can at times be heard without the use of a stethoscope.

Crackles in lungs when exhaling (breathing out)

Crackling when exhaling is not only an unsettling experience, but also it can also be very alarming, especially given the fact that it is at times described as the death rattle. In some cases, the causes are life threatening, while in other times the sounds are caused by everyday conditions.

It is recommended that you try to take note of crackling when you are exhaling air from your lungs. Cracking when exhaling can be caused by conditions such as:

Blockage

When blockage is behind the crackling in lungs when exhaling, it could be due to an airway that has become blocked or because of the presence of pressure on the areas outside your lungs. When there is excess pressure, it may lead to the collapse of your lungs, and this will result in your lungs not receiving any air.

Blockage can be brought about by the presence of a foreign body in your air passage, mucus, tumors, and much more. The pressure outside the lungs on the other hand may be due to;

• Injuries
• Tumors
• Pleural effusion, or scarring of your lungs.
