Spirometry
Advanced Pulmonary Function Testing

At M R Hospitals, Thanjavur, our Spirometry service provides a simple, non-invasive assessment of lung function and breathing capacity.
Spirometry is an important pulmonary function test used to evaluate how much air a person can breathe out and how quickly they can exhale. It helps doctors diagnose, assess and monitor a range of respiratory conditions. 

What Is Spirometry?

During spirometry, the patient breathes into a specialised device called a spirometer.
The test measures important parameters including:

• Forced Vital Capacity (FVC) – the amount of air that can be forcefully exhaled after a full breath in
• Forced Expiratory Volume in 1 second (FEV₁) – the amount of air exhaled during the first second
• FEV₁/FVC ratio – an important indicator of airflow obstruction
• Other flow and volume measurements

The results are compared with expected values based on factors such as age, sex and height. 

When Is Spirometry Recommended?

Your doctor may recommend spirometry for:
• Persistent cough
• Breathlessness
• Wheezing
• Recurrent respiratory symptoms
• Reduced exercise tolerance
• Suspected asthma
• Suspected chronic obstructive pulmonary disease (COPD)
• Assessment of other respiratory disorders
• Monitoring known lung disease 

Diagnostic Mammography

Mammography can also be used to investigate breast symptoms or abnormalities identified during clinical examination or other imaging.

It may be recommended for:
• A breast lump
• Breast pain requiring further evaluation
• Nipple discharge
• Changes in breast shape or appearance
• Skin or nipple changes
• Abnormal findings on another breast investigation
• Follow-up of previously identified breast abnormalities

Diagnostic mammography may be complemented by breast ultrasound or other investigations when required. 

Mammography & Breast Cancer

Mammography plays an important role in the early detection of breast cancer.
When an abnormality is identified, further evaluation may include:
Clinical Examination → Mammography → Ultrasound / Additional Imaging → Tissue Diagnosis When Required → Specialist Treatment
If a suspicious lesion requires tissue diagnosis, appropriate biopsy and pathology services can be arranged.
Patients diagnosed with breast cancer can be evaluated through our multidisciplinary surgical and oncology services for appropriate treatment planning.

Comprehensive Breast Care

Breast health often requires more than a single investigation.
At M R Hospitals, patients can access coordinated care involving:
• Breast imaging
• General and breast surgical services
• Oncology
• Pathology
• Anaesthesia
• Other specialist services when required
This provides a seamless pathway from screening and diagnosis to definitive treatment.

Other Cardiac Conditions

Echocardiography can contribute to the evaluation of conditions such as cardiomyopathy, heart failure and other structural or functional cardiac disorders


Spirometry in Asthma & COPD

Asthma
Spirometry can help assess airflow limitation and, in appropriate circumstances, evaluate changes in lung function after bronchodilator medication.
COPD
Spirometry plays an important role in establishing the presence and severity of persistent airflow limitation in patients suspected of having COPD.
Regular testing may also help monitor lung function over time.
