Mediflo Duo

Please note, this page is printable by selecting the normal print options on your computer.

The Mediflo Duo is a respiratory device to help make breathing feel easier and help clear sputum off your chest. It must be done in a relaxed, upright seated position.

Equipment
The Mediflo Duo device has 2 functions to help your breathing in and breathing out. It consists of the following parts:
• A detachable white plug.
• A detachable ribbed hose with a mouthpiece attached.
• A container with a ball in it.
• A twistable blue lid on top of the container (see separate picture).

It can be set up two different ways to achieve different results:
1) Incentive spirometry allows you to see how you are doing to encourage a slow deep breath in, which in turn will help you to get air to all areas of your lungs.
2) Positive expiratory pressure (PEP) involves blowing out against a resistance. This helps by opening up your airways and allowing air to get to all areas of your lungs, to help clear secretions.

Your Physiotherapist will set up and demonstrate the device mode suited to your needs.

Incentive Spirometry
– Breathing in
Set up the device as shown in the picture below:

Blue = stopper; Transparent tube = hose

Turn the blue cover onto the blue scale of numbers to select a value between 1 and 6 (1 being the hardest and 6 being the easiest). Choose the setting that feels comfortable to be able to breathe in slowly, continuously and deeply, to keep the ball afloat for as long as possible.

Procedure for incentive spirometry
1. You should sit as upright as possible.
2. Hold the Mediflo duo in one hand and the mouthpiece in the other.
3. Breathe in through the mouthpiece slowly, continuously and as deeply as possible so that the ball floats for as long as possible.
4. Hold your breath for a further few seconds, remove the mouthpiece and breathe out slowly.
5. Complete 4 normal sized breaths without the device.
6. Repeat the breathing exercise with the device 6 times.

The scale value can be increased as training progresses.

Positive Expiratory Pressure (PEP) – Breathing out
Adjust the device and set it up as shown in the picture below:

Turn the blue cover on the yellow scale of numbers to select a value between 1 and 6 (1 being the hardest and 6 being the easiest). Choose the setting that feels comfortable to be able to use to take a deep breath then blow out slowly, continuously, to keep the ball afloat for as long as possible.

Procedure for PEP
1. You should sit as upright as possible.
2. Hold the Mediflo duo in one hand and the mouthpiece in the other.
3. Breathe in deeply and then breathe out through the mouthpiece slowly, continuously so that the ball floats for as long as possible.
4. Remove the mouthpiece and breathe in again slowly.
5. Complete 4 normal sized breaths without the device.
6. Repeat the breathing exercise with the device 6 times.

The scale value can be increased as training progresses.
