[Audio] COMMON ERRORS OF INHALER TECHNIQUES (FOCUS ON PMDI) 08/07/2026 group members : hari pretha norashikin maimon siti nur ain nur hidayah shyairah.

[Audio] OBJECTIVES 1) To identify the common errors that patients make while using a pressurized metered-dose inhaler (pMDI). 2) To explain the impact of incorrect inhaler technique on medication delivery and disease control. 3) To discuss strategies for preventing and correcting common pMDI technique errors through patient education..

[Audio] INTRODUCTION Medication use has always played a highly significant role in the overall management of asthma, with appropriate use being linked to good asthma control. However, while patients with asthma enjoy the 'luxury' of having medications delivered directly to the lungs via inhaler devices, with that comes the additional challenge of ensuring that inhaler devices are used correctly. Research and practice provides evidence to the challenges associated with inhaler use and the particular steps that patients perform incorrectly..

[Audio] INHALER TECHNIQUE AND ASTHMA CONTROL When it comes to inhaler use, it is accepted that we have a longstanding problem. (Example: High proportion of patients using inhalers do so incorrectly) Poor inhaler technique is associated with suboptimal asthma control, disease instability, and increased hospital visits. Its burden extends directly onto health care costs, with one-quarter of the costs associated with inhaler use being associated with poor inhaler technique.

[Audio] INHALER USE IN PRACTICE: THE IMPORTANCE OF SPECIFIC STEPS AND ERRORS In recognizing the impact of inhaler technique on disease control, there are several important details to consider about the specific steps required to use an inhaler correctly. 1 Firstly, here are many different inhalers available, each requiring a set of specific steps for correct use.

[Audio] 2 Secondly, for each type of inhaler, some steps are more likely to be completed erroneously than others. Two of the most commonly made errors for the pressurized metered dose inhaler (pMDI) Failing to press the inhaler while breathing in slowly. Failing to breath hold after completion of dosing..

[Audio] 1) INHALER DEVICE IS NOT SHAKEN BEFORE USE Insufficient shaking of the canister can lead to inhaler malfunctioning and cause inconsistent dosing..

[Audio] 2.Inhaler device is not primed before use.

[Audio] 3) NOT FULLY BREATHING OUT BEFORE USING INHALER Breathing out completely, or as much as is comfortable, helps opens up the airways to receive more air on the subsequent breath. This leads to a deeper inhalation than usual, which maximizes the drug's ability to reach its target site of action..

[Audio] 3.Not fully breathing out before using inhaler.

[Audio] 4) POOR DEVICE POSITIONING/POSTURE The inhaler should be used with the patient's chin up or head slightly inclined back. The mouthpiece needs to be properly positioned in the mouth, and the lips need to press tightly over it..

[Audio] 5) POOR HAND-MOUTH COORDINATION The patient must breathe in while pressing the canister simultaneously in order for the medication from the MDI to reach the lungs..

[Audio] 6) NOT HOLDING YOUR BREATH AFTER INHALATION Holding breath will help increase the lung deposition through sedimentation. Because of gravity, more particles will settle on the receptor sites once the air is quiet for a brief period of time..
