Pulmonology Evaluations and Diagnosis

Accurate diagnosis is essential for effective lung care. Pulmonology tests assess lung function, detect respiratory conditions, and guide treatment plans. Early testing improves outcomes and helps prevent complications.

Common Screening Tests for Lungs

Diagnosing respiratory issues begins with understanding how well the lungs are working. At LIV Hospital, we use routine screening tests to detect problems early. These tests are non-invasive and help us create the right treatment plan for both adults and children.

Standard diagnostic tools include:

Pulse Oximetry: A small clip placed on the finger to measure oxygen levels in the blood.
Spirometry: A breathing test where you blow into a tube to measure airflow and lung volume.
FeNO Test: Measures inflammation in the airways, commonly used to diagnose asthma.
Peak Flow Measurement: A simple handheld device that checks how fast you can push air out of your lungs.

Advanced Diagnostic Procedures

When routine tests do not provide enough information, we use advanced methods to look deeper. These procedures allow our pulmonologists to examine the airways directly or test for specific genetic conditions.

Specialized testing options:

Bronchoscopy: A flexible tube with a camera is passed down the throat to view the airways.
Sweat Chloride Test: The gold standard for diagnosing Cystic Fibrosis, particularly in children.
Polysomnography (Sleep Study): Monitors breathing, heart rate, and oxygen levels during sleep to diagnose sleep apnea.
Lung Biopsy: Removing a small sample of lung tissue to test for diseases like fibrosis or cancer.

Imaging Techniques for Lung Health

Imaging plays a crucial role in seeing the structure of the lungs. We use state-of-the-art technology to capture detailed pictures of the chest. For our pediatric patients, we prioritize low-dose radiation protocols to ensure safety.

Key imaging methods:

Chest X-ray: The first step to checking for pneumonia, collapsed lungs, or heart problems.
CT Scan (Computed Tomography): Provides detailed cross-sectional images to spot small tumors or blood clots.
MRI (Magnetic Resonance Imaging): Uses magnets to look at soft tissues and blood vessels without radiation.
Fluoroscopy: A continuous X-ray movie that shows how the lungs move while breathing.

What to Expect During Bronchoscopy

Bronchoscopy is a common advanced procedure. Knowing the steps helps reduce anxiety for patients and parents. We ensure comfort through sedation or anesthesia, especially for children.

Step-by-step procedure:

Preparation: A numbing medicine is sprayed into your nose and throat to minimize discomfort and prevent gagging during the procedure.
Sedation: A sedative is administered through an IV line to help you relax; in some cases, you may even fall into a light sleep.
Insertion: The bronchoscope, a thin, flexible tube with a camera, is gently inserted through the nose or mouth and guided down into the airways.
Examination: The doctor carefully inspects the airways for inflammation, blockages, or abnormalities. They may also flush the area with a sterile solution (bronchial washing) or collect a tissue sample (biopsy) if needed.
Recovery: After the procedure, you will be monitored until the sedation wears off and your swallowing reflex returns, ensuring you can eat and drink safely before going home.

How to Prepare for Lung Tests

Proper preparation ensures accurate results. Your doctor will give you specific instructions based on the test and the patient’s age. For children, we recommend explaining the test in simple words beforehand to keep them calm.

General preparation guidelines:

Fasting: You may need to stop eating or drinking for 4-8 hours before tests requiring sedation.
Medications: Ask your doctor if you should stop taking inhalers or other medicines before the test.
Clothing: Wear loose, comfortable clothes that do not restrict breathing.
Comfort Items: For children, bringing a favorite toy or blanket can help reduce stress during the visit.

Understanding Your Test Results

After your tests are completed, our team carefully reviews the data to establish an accurate diagnosis. Understanding your results is an important part of your care, so we take the time to explain each finding clearly to you and your family. Some tests, such as spirometry or X-rays; may provide immediate insights that can be discussed during the same visit. Others, like biopsies or blood tests, require laboratory analysis and may take several days to process.

Once all results are ready, we schedule a follow-up appointment to review more complex findings and outline the next steps in your treatment plan. During this discussion, we clarify whether your results fall within normal or abnormal ranges, comparing your lung function to expected values for someone of your age, height, and overall health. This understanding helps you stay informed and engaged in your respiratory care journey.

FREQUENTLY ASKED QUESTIONS

What tests are used to diagnose pulmonary conditions?

Common tests include spirometry to measure airflow, pulse oximetry for oxygen levels, and chest X-rays. Advanced conditions may require CT scans, bronchoscopy, or genetic testing like the sweat test for Cystic Fibrosis.

How do I prepare for a lung function test?

You should wear loose clothing and avoid large meals before the test. Your doctor may ask you to stop using certain inhalers for a few hours beforehand. Avoid caffeine and smoking before the test as they can affect the results.

Is bronchoscopy painful?

No, bronchoscopy is not typically painful. You will receive numbing medicine for your throat and sedation to make you comfortable. You may feel a mild sore throat or cough for a day or two after the procedure.

How accurate are pulmonology diagnostic tests?

Pulmonology diagnosis tools are highly accurate. Tests like spirometry and CT scans provide precise data on lung function and structure. When combined with a physical exam and medical history, they allow for a very reliable diagnosis.

When do I need advanced imaging or testing?

Advanced testing is needed if basic tests like X-rays or spirometry do not explain your symptoms. It is also used if your doctor suspects a complex condition like interstitial lung disease, a tumor, or a congenital defect in children.
