What Is a Spirometry Test?
Spirometry is a physiological test used to measure lung capacity and airflow, helping assess how effectively the lungs inhale and exhale air over time. It is a key tool for evaluating lung function measurement and identifying airflow abnormalities.
Why Is the Spirometry Test Performed?
Spirometry is performed to screen, diagnose, and monitor respiratory conditions that affect breathing. It helps detect airflow limitation, assess disease severity, and track changes in lung function over time
How Does the Spirometry Test at Home Work?
Spirometry test at home allows individuals to undergo lung function screening in a familiar and convenient setting. The test is conducted using a portable spirometry device under guided supervision. The individual is instructed to take a deep breath and exhale forcefully into the device, which records airflow and volume measurements. The results are generated through the Spirofy software system.
What are the indications of the spirometry test?
- Screening and evaluation of airflow limitation in conditions such as Chronic Obstructive Pulmonary Disease (COPD) and asthma.
- Pre-operative lung function assessment in patients undergoing cardiothoracic or major non-cardiothoracic surgery.
- Assessment of patients with suspected chronic lung diseases, including COPD and other obstructive or restrictive lung disorders.
- Evaluation of lung function impairment in conditions such as asthma, bronchiectasis, interstitial lung disease (ILD), and neuromuscular disorders.
- Monitoring lung function over time in patients with chronic respiratory diseases such as COPD, asthma, ILD, and bronchiectasis.
- Assessment of residual lung impairment after pulmonary infections such as tuberculosis (post-TB lung disease).
What are the contraindications of the spirometry test?
- Spirometry may not be suitable in certain conditions due to safety concerns or reduced test accuracy, including:
- Unstable cardiovascular status such as myocardial infarction
- Recent thoracic or abdominal surgery
- Recent eye or ear surgery
- Proven or suspected active pulmonary tuberculosis
- Thoracic, abdominal or cerebral aneurysm
- Oral or facial pain exacerbated by the device mouthpiece
- Hemoptysis of known/unknown origin
- Uncontrolled blood pressure
- Acute illnesses that may interfere with the performance of the procedure such as acute respiratory tract infection, nausea, vomiting, chest pain, or abdominal pain
What are the key highlights of the spirometry test?
Key highlights of the Spirometry At-Home includes the following :
- Helps in early screening of individuals at risk of having pulmonary disease
- Assesses general respiratory health
- Preemployment and lung health monitoring for at-risk occupations

Step-by-Step Home Spirometry Procedure
- The individual is guided on proper posture and breathing technique
- A deep inhalation is followed by a forceful and sustained exhalation into the mouthpiece
- The maneuver may be repeated to ensure acceptable and reproducible readings
- Lung function data is captured digitally and analyzed by the software
Parameters Measured in a Spirometry Test
A spirometry test measures key lung function parameters that reflect airflow and lung capacity. These values help identify potential breathing abnormalities and assess overall respiratory performance.
Key Lung Function Measurements (FEV₁, FVC, FEV₁/FVC)
FEV₁ (Forced Expiratory Volume in 1 second): Measures the amount of air exhaled in the first second of a forceful breath
FVC (Forced Vital Capacity): Represents the total volume of air exhaled after a full inhalation
FEV₁/FVC Ratio: Helps differentiate between obstructive and restrictive lung patterns
These parameters together provide a comprehensive overview of lung function and breathing efficiency.
Note: This is a screening test. The spirometry at home test report is software-generated using Spirofy and does not involve doctor or laboratory.
