Video Inhaler Part 2 Versi 3

Summary

This educational video provides an in-depth explanation of inhalation therapies, focusing on Metered Dose Inhalers (MDIs) and Dry Powder Inhalers (DPIs). It explains how MDIs deliver medication in an aerosol form, highlighting their advantages and challenges, including environmental impact and the need for coordination during use. The video also covers DPIs, which offer a propellant-free, breath-activated alternative. DPIs come in various types, including unit-dose, multi-dose, and reservoir devices, each with its own set of benefits and limitations. The content is aimed at improving understanding and proper usage of inhalers, particularly for patients with asthma or COPD.

Takeaways

• 😀 MDIs deliver a precise dose of medication through a pressurized canister, with medication aerosolized during use.
• 😀 MDIs must be shaken before use to mix the medication and propellant, ensuring proper delivery of the drug.
• 😀 One of the key challenges of using MDIs is the need to coordinate pressing the canister and inhaling the aerosol simultaneously.
• 😀 Spacer devices can be used with MDIs to help patients, particularly children or those with cognitive issues, inhale correctly.
• 😀 MDIs contain propellants such as Hydrofluoroalkanes (HFA), which are more environmentally friendly than older Chlorofluorocarbons (CFCs), but still contribute to greenhouse gas emissions.
• 😀 Dry Powder Inhalers (DPIs) do not require propellants, making them a more environmentally friendly alternative to MDIs.
• 😀 DPIs are breath-activated, meaning they are triggered by the patient's inhalation, eliminating the need for coordination between inhalation and activation.
• 😀 Strong inspiratory flow is required to activate DPIs, making them less suitable for children under six or patients with poor lung capacity.
• 😀 There are three types of DPI devices: unit dose, multiple unit dose, and reservoir devices, with each offering different mechanisms for medication delivery.
• 😀 Devices like Breezhaler and Turbohaler offer benefits such as easier use, no propellant, and improved environmental impact, but require sufficient breath strength for proper inhalation.

Q & A

What is the main function of a Metered Dose Inhaler (MDI)?

The main function of an MDI is to deliver a precise and specific dose of medication in each puff, using a pressurized canister to aerosolize the drug for inhalation.

What are the two main components of an MDI?

The two main components of an MDI are the pressurized canister, which contains the medication and propellant, and the plastic cover that protects the canister.

Why is it necessary to shake an MDI before use?

Shaking the MDI before use ensures that the liquid medication and propellant mix properly, which is crucial for the accurate delivery of the medication.

What are some environmental concerns associated with MDIs?

MDIs use propellants like chlorofluorocarbons (CFCs) and hydrofluoroalkanes (HFAs), which contribute to ozone depletion and greenhouse gas emissions, negatively impacting the environment.

How does the use of a spacer help MDI users?

A spacer helps MDI users by allowing them to inhale the medication in multiple breaths, which is useful for patients with difficulty holding their breath or those requiring assistance, such as children or elderly individuals.

What is the main advantage of using a Dry Powder Inhaler (DPI) over an MDI?

A key advantage of DPIs is that they do not require a propellant, making them more environmentally friendly compared to MDIs. They are also breath-activated, which simplifies usage.

Why are DPIs generally not recommended for children under 6 years old?

DPIs are not recommended for children under 6 years old because they have lower inspiratory flow rates, which may not be sufficient to properly disperse the medication from the inhaler.

What is the role of the carrier particles in a DPI?

Carrier particles, typically larger than the drug particles, are used in DPIs to improve the flow of the drug powder, ensuring proper dispersion and inhalation into the lungs.

What is the primary difference between a unit-dose DPI and a reservoir device?

A unit-dose DPI requires the patient to load a new dose of medication from a capsule or blister before each use, while a reservoir device contains a built-in storage unit that holds multiple doses of medication.

What is the recommended inhalation technique for using a Turbohaler?

To use a Turbohaler, the patient should twist the device to load the dose, inhale rapidly and deeply through the mouthpiece, hold their breath for 10 seconds, and then exhale gently. If more doses are needed, the process is repeated.
