Question

drag the instructions for how to use a peak flow meter into the correct order.
1 take a deep breath
2 take a short break and then repeat for two more breaths
3 record the highest reading only
4 exhale as hard and fast as possible
5 place peak flow meter in mouth and close lips tightly around mouthpiece
6 stand up straight and remove any gum or food from mouth
7 set the peak flow meter to zero

Explanation:

To use a peak flow meter correctly, the first step is to prepare: stand straight and clear the mouth (Step 6). Then set the meter to zero (Step 7). Next, place the meter in the mouth (Step 5). Take a deep breath (Step 1), then exhale hard and fast (Step 4). After that, take a short break and repeat twice (Step 2). Finally, record the highest reading (Step 3). So the correct order is: 1. Stand up straight and remove any gum or food from mouth; 2. Set the peak flow meter to zero; 3. Place peak flow meter in mouth and close lips tightly around mouthpiece; 4. Take a deep breath; 5. Exhale as hard and fast as possible; 6. Take a short break and then repeat for two more breaths; 7. Record the highest reading only.
