Spirometry in Asthma
You would not consider managing
hypertension without a
sphygmomanometer, or diabetes
without a glucometer –
accurate and objective
assessment and management of
asthma is not possible without a
spirometer.

National Asthma Council, Melbourne, 2002
Classification of
Asthma Severity

Multi-faceted severity assessment
 Symptoms

Nocturnal awakenings
 Rescue medication use
 Physiologic measure
 FEV1
 PEFR variability
Overwhelming tendency to under-categorize
severity of disease
 Subjective assessment often not accurate “poor
perceivers”
 Severity is based upon “worst” category


Daytime/ exercise tolerance
Utility of Spirometry in COPD
Spirometry should be undertaken in all patients who may have
COPD. It is needed to make a confident diagnosis of COPD
and to exclude other diagnoses that may present with similar
symptoms. Although spirometry does not fully capture the
impact of COPD on a patient’s health, it remains the GOLD
STANDARD for diagnosing the disease and monitoring its
progression. It is the best standardized, most reproducible,
and most objective measurement of airflow limitation available.
Good quality spirometric measurement is possible and all
health care workers who care for COPD patients should have
access to spirometry.

or exhales a volume of air as a function of time.

Emphysema
 Non-reversible obstruction
 Decreased DLCO
Fibrosis
 No obstruction

 Low TLC
 Low VC and normal ratio alone don’t indicate restriction
 Low DLCO
 Low DLCO may appear before decline in TLC
Obesity
 Often restricted
 DLCO usually high but variable

Testing Methodology


Closed circuit method: Patient able to place
mouthpiece in mouth and perform tidal breathing.
Test maneuver is accomplished from tidal breathing
baseline. (PREFERRED METHOD)
Open circuit method: Requires that patient initiate
test maneuver (inspiration to TLC, maximal
expiration to RV) immediately upon placing
mouthpiece in mouth. Requires higher degree of
motor skills, quicker reaction time to coaching.

Spirometry in Children
Harvey Leo M.D.
Asthma Management Children

ATS guidelines suggest that children 5
years and older can do spirometry


Practically, children 8 years and older can
produce consistent spirometry
Normal values for children can be
misleading

Reversibility studies may be useful if
technique is adequate
 Some children cannot meet full ATS criteria
Spirometry in Children





Solid coaching is essential for appropriate
diagnosis
Child’s effort is essential
Positioning and mouthpiece size important
FEV1 and FEV1/FVC are the main
measure
FEF25-75 can be useful since it is effort
independent
Other Measurement Tools


Exhaled nitric oxide can be useful in young
children not able to perform spirometry if
needed
If there is no improvement clinically or by
spirometry, referral is needed

Flexible bronchoscopy or full PFT may be
needed
General Guidelines in Children



Any child being placed on inhaled
corticosteroids (ICS) should have
spirometry measurements as baseline
Good measurement of height/weight are
essential for comparison
If child is on ICS, visits every 4-6 months
recommended
