Peak Flow Meter
If your doctor has told you or your child to monitor lung function at home, or if you are a hospital or clinic looking for reliable pulmonary function testing equipment, you are in the right place. At Medical Supplies PK, we stock a complete range of lung function monitoring devices — from affordable incentive spirometers for post-surgical patients to advanced desktop clinical spirometers used in pulmonary labs and hospitals — all available with fast delivery across Pakistan.
What Is a Peak Flow Meter?
A peak flow meter is a small, handheld, non-powered device that measures how fast you can push air out of your lungs in a single forced exhalation. This measurement is called Peak Expiratory Flow (PEF) and is recorded in litres per minute (L/min).
Peak flow meters are primarily used for asthma management. Since asthma causes narrowing of the airways, a falling peak flow reading — even before symptoms appear — signals that an attack may be coming. Regular monitoring gives patients and doctors an early warning system, allowing medication to be adjusted before breathing becomes seriously impaired.
Peak flow meters are recommended by the Global Initiative for Asthma (GINA) guidelines as a standard self-monitoring tool for moderate and severe persistent asthma. They are also used in patients with chronic bronchitis and emphysema for routine lung function tracking.
What Is a Spirometer? How Is It Different from a Peak Flow Meter?
A spirometer is a more advanced lung function measuring device. While a peak flow meter only measures the speed of exhalation (PEF), a spirometer measures multiple parameters of both inhalation and exhalation — making it far more diagnostically powerful.
The table below explains the key differences:
| Feature | Peak Flow Meter | Spirometer |
|---|---|---|
| What it measures | Peak Expiratory Flow (PEF) only | FVC, FEV1, FEV1/FVC, PEF, FEF25/50/75, MVV, and more |
| Primary use | Asthma monitoring at home | Diagnosing & monitoring asthma, COPD, emphysema, fibrosis |
| Technology | Simple mechanical device | Digital / electronic |
| Used by | Patients at home | Clinics, hospitals, pulmonary labs |
| Cost | Very affordable | Moderate to high |
| Power required | None | Battery or USB |
| Result output | Single number (L/min) | Full report with graphs (Flow-Volume, Volume-Time curves) |
| Best for | Asthma daily monitoring | Comprehensive pulmonary function testing (PFT) |
Which device do you need?
- If you are an asthma patient monitoring daily breathing at home Peak Flow Meter
- If you are a post-surgery patient doing breathing exercises Incentive (3-Ball) Spirometer
- If you are a clinic or hospital doing lung function diagnostics for COPD, asthma, or pre-surgery evaluation Digital Spirometer (SP80B or SP100A)

1. Tri-Ball Incentive Spirometer — Besmed Taiwan | Rs. 900
The Besmed Tri-Ball Incentive Spirometer is a simple, non-powered device designed for post-surgical lung rehabilitation. After any major surgery — especially cardiac, thoracic, or abdominal operations — patients are at risk of partial lung collapse (atelectasis) due to shallow breathing. The incentive spirometer encourages patients to breathe in slowly and as deeply as possible, providing visual feedback through three color-coded balls inside the chamber.
How it works: As the patient inhales through the mouthpiece, the negative pressure lifts the balls inside the three chambers. The target is to raise all three balls by inhaling at the correct sustained flow rate. This trains lung volume and prevents post-surgical complications.

Frequently Asked Questions
Q: What is a normal peak flow reading? Normal peak flow varies by age, height, and sex. Adult males typically range from 400–700 L/min and adult females from 300–500 L/min. The most important number is your personal best — your peak flow should not drop more than 20% below your personal best. If it does, consult your doctor immediately.
Q: At what age can a child start using a peak flow meter? Children as young as 5 years can typically use a standard peak flow meter with proper technique guidance from a parent or healthcare provider.
Q: What is the difference between an incentive spirometer and a peak flow meter? An incentive spirometer measures inhalation — it trains you to breathe IN deeply and is used for lung rehabilitation after surgery. A peak flow meter measures exhalation speed (PEF) and is used to monitor asthma control. They serve different purposes and are not interchangeable.
Q: Can a peak flow meter diagnose asthma? A peak flow meter alone cannot diagnose asthma — it is used for monitoring, not diagnosis. For diagnosis, a full spirometry test (FVC, FEV1, FEV1/FVC) done with a digital spirometer before and after bronchodilator is the standard clinical method.
Q: Is the Contec SP80B spirometer suitable for home use? The SP80B is a professional-grade device designed for clinical use, but it can be used at home by patients under physician supervision. For simple daily asthma tracking, a basic peak flow meter is more practical and affordable.
Q: Do you offer the SP100A for hospital procurement or bulk purchase? Yes. For hospital procurement, institutional orders, or bulk purchases, contact us directly or WhatsApp (+92) 340 4429747 for pricing and delivery arrangements.
