How to Use This Calculator
- Select your inhaler device type (pMDI, DPI, pMDI + Spacer, or SMI).
- Rate each technique step as correct or incorrect: cap removal / dose loading, shake or prime, exhale before inhaling, lip seal, coordinating the press with inhalation, inhalation quality, breath-hold, and waiting between puffs.
- Review your technique score (%), steps correct out of the total for your device, and the number of critical errors.
- Read the help text for each step to identify and correct technique errors.
- Check the grade and estimated drug delivery (%) -- poor technique lowers lung deposition, so review results with a pharmacist or respiratory therapist.
What each input means
- Device Type
- Select inhaler device type.
- Remove Cap / Load Dose
- Correctly removed cap and prepared device for use.
- Shake / Prime
- Shook inhaler (pMDI) or primed device appropriately.
- Exhale Before Inhaling
- Exhaled fully away from mouthpiece before inhalation.
- Proper Lip Seal
- Sealed lips tightly around mouthpiece.
- Coordinate Press & Inhale
- Pressed canister at start of slow deep inhalation (pMDI/SMI).
- Proper Inhalation
- Slow deep breath (pMDI) or quick forceful breath (DPI).
- Breath Hold 5-10s
- Held breath for 5-10 seconds after inhalation.
- Wait 30-60s Between Puffs
- Waited 30-60 seconds before next puff if applicable.
What each result means
- Technique Score (%)
- Percentage of inhaler steps performed correctly.
- Steps Correct
- Number of steps performed correctly.
- Total Steps
- Total critical steps for this device type.
- Critical Errors
- Number of critical errors that significantly reduce drug delivery.
- Grade (0=Poor to 3=Excellent)
- 0 = Poor (<50%), 1 = Fair (50-74%), 2 = Good (75-89%), 3 = Excellent (90-100%).
- Est. Drug Delivery (%)
- Estimated percentage of drug reaching the lungs based on technique quality.
