Dangers of Phlegm Buildup in the Respiratory Tract: Don't Underestimate It

Phlegm is often considered normal when someone has a cold or cough. However, in certain conditions, phlegm buildup can become a serious problem that interferes with breathing and even threatens a patient's safety. Especially in patients who are unable to clear phlegm independently, accumulated mucus can cause airway obstruction and trigger various complications.

So, who is at risk of experiencing this condition? What causes it? And how is it managed? See the following explanation.

What is Phlegm Buildup?

Phlegm or sputum is mucus produced by the respiratory tract as the body's natural mechanism to trap dust, bacteria, viruses, and foreign particles from entering deeper into the lungs.

Under normal conditions, phlegm is expelled through the cough reflex. However, in some medical conditions, a person does not have enough coughing strength, causing phlegm to continue to accumulate in the respiratory tract.

As a result, the breathing process becomes more difficult, and the risk of airway obstruction increases.

Causes of Difficulty Expelling Phlegm

Not everyone can effectively clear phlegm. Some conditions that often cause mucus buildup include:

1. Stroke

Stroke patients often experience swallowing difficulties and weakening of throat muscles, making the cough reflex ineffective.

As a result, mucus remains in the respiratory tract and risks causing lung infections.

2. Post-Surgery

After undergoing surgery, especially surgery with general anesthesia, patients are usually still weak and find it difficult to cough maximally.

In addition, pain in the surgical area also makes patients reluctant to cough, making phlegm more likely to accumulate.

3. Chronic Lung Disease

Patients with COPD, chronic bronchitis, bronchiectasis, and pneumonia generally produce more phlegm than healthy individuals.

If phlegm is not expelled, lung function can further decline.

4. Nerve Disorders

Diseases such as Parkinson's, ALS, brain injury, and spinal cord injury can impair the ability to cough and swallow, making the airway more easily obstructed.

5. Patients with Decreased Consciousness

Patients in the ICU, on ventilators, or experiencing decreased consciousness are often unable to clear their airways on their own.

Symptoms of Phlegm Buildup to Watch Out For

Some signs indicating phlegm buildup include:

• Gurgling or rattling breath sounds.
• Coughing but difficulty expelling phlegm.
• Heavy or short breath.
• Increased breathing rate.
• Bluish lips or fingertips due to lack of oxygen.
• Fever if a lung infection has occurred.

If symptoms worsen with severe shortness of breath or decreased consciousness, the patient requires immediate medical attention.

Dangers of Untreated Phlegm Buildup

Many people think that phlegm only causes discomfort. However, if left untreated for too long, this condition can lead to serious complications.

Airway Obstruction

Thick mucus can partially or completely block the airway, disrupting oxygen flow to the lungs.

Pneumonia

Phlegm is an ideal environment for bacteria to multiply. Mucus buildup can increase the risk of lung infection or pneumonia.

Decreased Oxygen Levels

When air has difficulty entering the lungs, oxygen levels in the blood decrease, so body organs do not receive sufficient oxygen supply.

Respiratory Failure

In severe conditions, mucus obstruction can lead to respiratory failure requiring ventilator support and intensive care.

How to Help Clear Phlegm

Treatment depends on the cause and condition of the patient. Some common steps include:

• Ensuring the body stays hydrated to thin the phlegm.
• Performing chest physiotherapy as advised by medical personnel.
• Changing the patient's position periodically.
• Administering medication as prescribed by a doctor if necessary.
• Assisting in clearing the airway using a suction device for patients unable to clear phlegm themselves.

It is important to note that phlegm suction should be performed by healthcare professionals or caregivers who have received education on the correct procedure to ensure it is safe and effective.

The Role of Phlegm Suction Devices in Patient Care

In patients with a weak cough reflex, a phlegm suction device can help clear mucus from the respiratory tract, keeping the airway open and making the breathing process smoother.

One popular choice is the General Care SS-6A Portable Phlegm Suction Unit, a portable phlegm suction device designed to assist in patient care at home and in healthcare facilities. This device has a suction power of up to 18 L/minute, a maximum negative pressure of ≥0.075 MPa, a 1000 mL collection jar, and a relatively low noise level, making it more comfortable to use.

Nevertheless, the use of a suction device must follow the instructions for use and medical advice to ensure the procedure is performed safely.

When to See a Doctor Immediately?

Take the patient to a healthcare facility immediately if they experience:

• Severe shortness of breath.
• Bluish lips or nails.
• Decreased consciousness.
• High fever accompanied by a productive cough.
• Phlegm mixed with blood.
• Continuously decreasing oxygen saturation.

Do not delay examination as this condition can develop into an emergency.

Conclusion

Phlegm buildup is not just a common cough complaint. In patients with stroke, nerve disorders, chronic lung disease, or post-surgical patients, unexpelled mucus can potentially lead to airway obstruction, pneumonia, and even respiratory failure.

Patient condition monitoring, maintaining airway hygiene, and appropriate treatment are important steps to prevent complications. If the patient is unable to clear phlegm independently, the use of a suitable phlegm suction device performed with the correct procedure can help keep the airway clear as part of the care recommended by healthcare professionals.
