Metered Dose Inhaler (MDI) and Dry Powdered Inhaler (DPI) are the two most common devices
used to deliver medicine in conditions such as asthma and COPD. It is well-known that most
patients do not use correct technique when using a metered dose inhaler. This leads to poor
control of their disease. This study is being done so the investigators can record the
patient using the metered dose inhaler before and after a short teaching session. This
information will be fed into an invitro system (device) to allow the researchers to study
the effect of error on drug delivery. The device being used is the Rice R3 electronic
flowmeter.

Metered Dose Inhaler (MDI) and Dry Powdered Inhaler (DPI) are the two most common platforms
to deliver medicine for patients suffering from Asthma and COPD, and are used for dispensing
both controller and rescue medications. Despite well-known methods to manage Asthma and
COPD, nearly 70-90% of the patients do not display correct technique in using an inhaler
[8-14, 15]. Poor management and control of the disease due to inadequate inhaler usage has
resulted in rising rates of hospitalizations, making chronic respiratory diseases among the
top five causes of death worldwide. Through this study we aim to record the technique of MDI
usage among Asthma and COPD patient and understand the errors in their technique. The
various parameters of inhaler usage where patients can make an error are 1. Tidal volume,
inspiration flow rate, 3. Inspiration flow volume, 4. Timing of actuation of inhaler and 5.
Breath holding. The parameters will be recorded by the Rice R3 electronic flowmeter for each
patient and the errors in each MDI usage will be noted. Using ex-vivo modelling, the
patient's MDI technique recorded will be used to study the impact of errors in technique on
efficiency of MDI drug delivery.
