sophisticated spirometer using forced vital capacity maneuver in clinical setup
, whereas at home the patients with chronic air flow obstruction are often advised to carry out their PEF measurement using simple (and affordable) peak flow meters as …
What is peak flow used for?
Peak flow measurement is
a quick test to measure air flowing out of the lungs
. The measurement is also called the peak expiratory flow rate (PEFR) or the peak expiratory flow (PEF). Peak flow measurement is mostly done by people who have asthma.
What does peak flow tell you?

How is peak flow determined?
The peak flow meter works
by measuring how fast air comes out of the lungs when you exhale forcefully after inhaling fully
. This measure is called a “peak expiratory flow,” or “PEF.” Keeping track of your PEF, is one way you can know if your symptoms of asthma are in control or worsening.
How does a peak flow meter help a patient CVS module?
A peak flow meter measures how fast air comes out of your lungs when you exhale forcefully. Readings from the meter can help you or your child recognize
early signs of worsening asthma
.
What happens if your peak flow is low?
If you get a peak flow score that’s lower than your best score, it can
act as an early warning sign and help you prevent an asthma attack
. It can also help you identify triggers, allergies, or infections that could be making your asthma worse.
What factors affect peak flow?
It is well known that
age, height and weight
are the main factors which affect the Peak Expiratory Flow Rate (PEFR), the Forced Expiratory Volume in the first second (FEV
1
) and the Forced Vital Capacity (FVC) [4].
What is the purpose of an asthma action plan?
An Asthma Action Plan is a written,
individualized worksheet that shows you the steps to take to keep your asthma from getting worse
. It also provides guidance on when to call your healthcare provider or when to go to the emergency room.
What instrument is used to measure a patient’s peak expiratory flow?
PEFR monitoring can be accurately performed by most patients older than 5 years. It is most commonly measured by a
portable flow gauge device
(peak flow meter [PFM]) but may also be obtained by a transducer that converts flow to electric output during spirometry (pneumotachometer).
What is a peak flow meter for COPD?
A peak flow meter is a small device that measures the amount of air a person can forcefully blow out of their lungs in one fast breath. It is one
indicator of airways changes
that may occur in people with asthma or COPD.
What should a peak flow reading be for a child?
| Height in inches Average peak flow Yellow Zone 50-80% of average peak flow | 44 160 80 – 128 | 45 173 87 – 139 | 46 187 94 – 150 | 47 200 100 – 160 |
|---|
What is the difference between peak flow and spirometry?
A spirometer assesses a patient’s lung function, however, it offers a larger
set of parametric values
regarding lung health than a peak flow meter does. Spirometry requires a patient to perform specific breathing maneuvers using a spirometer.
What are the advantages of utilizing a VHC spacer CVS?
Benefits of using a spacer
A spacer
gives someone more time to use the inhaler
, making the process simpler. It reduces the need for coordination when pressing the inhaler and breathing in the medicine. Spacers extend the amount of time the inhaler takes to deliver medicine.
How does asthma get diagnosed?
To diagnose asthma, your doctor will discuss your medical history with you and perform a physical exam. You may need a
lung function test
and maybe other tests, such as a chest or sinus X-ray. If you or your child are having problems breathing on a regular basis, don’t wait! Visit a doctor immediately.
How would you instruct a patient to determine his her personal best Pefr?
The patient is instructed to identify his or her personal best PEFR
by recording the highest number achieved within 2 weeks when he or she feels relatively well without respiratory symptoms
.
Which of these conditions occurs when the bronchial tubes are inflamed and as a result obstructed?
Which of these conditions occurs when the bronchial tubes are inflamed and, as a result, obstructed?
Asthma
.
Is a peak flow meter a spirometer?
Peak flow monitoring is
not the same
as spirometry and is only recommended as a guide to help you and your health professional monitor your lung function. Peak flow monitoring is not recommended to be used to confirm whether you have asthma.
How is an asthma action plan determined?

Can I use inhaler if I have Covid?
Your
reliever inhaler cannot help COVID-19 symptoms

Are asthma action plans effective?
The written asthma action plan was effective in
increasing the patients’ knowledge about their condition
, improving their quality of life and functional limitations, and increasing their confidence level about controlling their asthma.
What can affect lung capacity?
Physiological factors that influence lung volumes/capacities include
age, gender, weight, height and ethnicity, physical activity, altitude and others
, which should be considered while interpreting results of spirometry.
What conditions and diseases lead to a low peak flow?
Asthma
is the most common condition that affects peak flow. However, other conditions such as Chronic Obstructive Pulmonary Disease (COPD) that cause airway obstruction can also affect PEFR.
Why does age affect peak flow?
PEFR declines with advancing age due to degenerative changes in musculoskeletal system leading to decrease in
respiratory muscle strength
. PEFR shows some decline with high BMI in elderly age group.

Normal adult peak flow scores range between
around 400 and 700 litres per minute
, although scores in older women can be lower and still be normal.
