When Is an Inhaler Spacer Needed? Get to Know the Function of the ONEMED Spacer One 175ml
When using an inhaler, the medication needs to enter the respiratory tract with the correct technique to work as intended for treatment. However, using a MDI (Metered Dose Inhaler) is not always easy, especially for infants, children, the elderly, or people who have difficulty coordinating the timing between pressing the inhaler and inhaling.
This is where a spacer can help.
What Is an Inhaler Spacer?
A spacer is a chamber-shaped device used in conjunction with an MDI (Metered Dose Inhaler). This device acts as an intermediate space between the inhaler and the mouth or mask, allowing the aerosol medication to enter the chamber first before it is inhaled.
The use of a spacer can help optimize the delivery of medication from the inhaler into the respiratory tract, especially when MDI technique is not yet optimal.
However, a spacer is not a substitute for inhalation medication. Its use must still follow the prescription, type of medication, and instructions from a doctor or healthcare professional.
When Is a Spacer Needed?
A spacer can be a helpful tool when someone uses an MDI but experiences difficulty with inhalation technique.
Some conditions that may make a spacer more necessary include:
1. Infants and young children
Infants and children, especially those who are very young, are generally unable to coordinate the movement of pressing the inhaler with the timing of their inhalation correctly.
Therefore, using a chamber with a mask of the appropriate size can make the administration of inhalation medication easier.
2. Difficulty performing inhaler technique
When using an MDI, several steps must be performed in a coordinated manner. If the timing of pressing the inhaler and inhaling is not aligned, some medication may not be inhaled optimally.
A spacer can help provide space between the inhaler and the respiratory tract, making the inhalation process easier to perform.
3. People who require assistance when using an MDI
In addition to children, adults or the elderly who have difficulty following inhaler usage techniques may also require assistive tools like a spacer, as directed by a healthcare professional.

How to Use It?

Generally, the spacer is attached to the MDI according to the usage instructions. After the medication is released into the chamber, the user then inhales the medication through the mouthpiece or mask.
For infants and young children, the mask can help the administration process when they are unable to use the inhaler directly with the correct technique.
Important: Usage instructions may differ depending on the type of inhaler and medication used. Follow the product instructions and the directions of your doctor or healthcare professional.
Does Not Mean Every Inhaler User Must Use a Spacer
A spacer is not a device that must be used by everyone who uses an inhaler. Its need depends on the type of inhaler, the user's condition, their ability to perform the inhalation technique, and the advice of a doctor or healthcare professional.
If using an MDI feels difficult, especially for infants or children, ask your doctor or healthcare professional if a spacer is appropriate for use.
