The document discusses inhaler technique and common mistakes. It begins by outlining why proper inhaler technique is important for controlling asthma symptoms and outlines the types of inhalers. It then discusses the history of inhalers and demonstrates how to properly use different inhaler types like MDIs and DPIs. Common mistakes are described, such as not inhaling deeply enough or exhaling into the device. The document stresses the importance of checking patients' technique and providing education to use inhalers correctly.

WHY INHALER TECHNIQUESO
IMPORTANT?
Incorrect inhaler technique is a
common contributor to poor symptom
control of asthma1.
Incorrect inhaler technique is associated with 2,3:
an increase in reliever use
use of emergency services
worsening asthma control
higher rates of asthma instability.
Patients frequently revert to incorrect inhalation
technique after a short period so there is a need to regularly
check inhaler technique.4

INHALER TECHNIQUE
Inhaleddrugs are the most effective therapy
available for asthma and COPD, improvements in
inhaler technology and design in combination with
improvement in both physician and patient education
seems to be the way forward in improving asthma
management and control.5
Be aware that the risk of poor outcomes is
pronounced in patients using pressurized metered-
dose inhalers (pMDI) who have poor inspiration–
actuation coordination, but poor technique in
people using dry powder inhalers (DPIs) also leads to
poor outcomes. 2,3.

CHECK INHALER TECHNIQUE
In a clinical study, 90% of patients show incorrect inhaler
technique.8,9
Patients’ inhaler technique can be significantly improved by
brief instruction given by trained HCP
– However, 25% of patients have never received verbal
inhaler instruction.
– Only an estimated 11% of patients receive follow-up assessment
and education
Ask “Can you show me how you use your inhaler?”
– 75% of patients using an inhaler for on average 2-3 years
reported they were using their inhaler correctly but on checking
only 10% demonstrated correct technique.8.

Inhaling rapidly (some
VHCs whistle to alert
the patient to reduce
the rate of inhalation)
Exhaling instead of
inhaling after pressing
down on the canister
Failing to hold one’s
breath long enough
after a slow, deep
inhalation (10 seconds
is optimal)
COMMON MISTAKES WITHDPI
Shaking the DPI (it’s not required
with this type of device)
Forgetting to exhale gently before
inhaling
Exhaling into the device (exhalation
should be away from the DPI so the
breath doesn’t clump the powder)
Inhaling slowly (with most DPIs,
inhalation should be rapid)‡
Failing to inhale at sufficient
inspiratory flow rate†
Failing to load the dose‡
Do Not swallow the tablet

USING STEROID INHALER
In patients using an ICS preventer, failure to rinse with water and spit
after each dose increases the risk of local adverse effects such as oral
candidiasis and an increased risk of dysphonia caused by medicines
being deposited in the mouth and pharynx.
