Lung Capacity Data Collection Protocol 
1. Prior to Data Collection 
1) Equipment Preparation 
 Ensure that the spirometer is calibrated and fully charged. 
 For calibration, use the syringes and follow the instructions on the device.  
 Verify that all necessary supplies, such as mouthpieces, nose clips, and gloves, 
 are available and ready for use. 
 Make sure to have a zip bag with the subject’s name on it to store the  
 mouthpiece for the second data collection.  
2) Subject Preparation 
 Explain the purpose of the spirometry test to the subject and provide a brief  
 overview of the procedure. 
 Verify that the subject has not smoked, exercised vigorously, or consumed heavy  
 meals within the last 2 hours, as these factors can aƯect test results. 
 Ensure that the subject is wearing comfortable clothing that does not restrict  
 breathing. 
2. Test Selection & Subject Information Entry 
 Select “Forced Vital Capacity” on the device. 
 Record the subject’s sex by selecting the appropriate option from the drop-down  
 menu. 
3) Enter the subject’s age in years. 
3. Pre-Test Setup 
 Instruct the subject to sit upright with their back against the chair. Their shoulders  
 should be relaxed, eyes open, and feet ﬂat on the ﬂoor with legs together. 
 Apply a nose clip to ensure the subject cannot breathe through their nose. 
 Provide the subject with the spirometer mouthpiece and instruct them to securely  
 place it in their mouth. 
4. Spirometry Test Procedure 
 Ask the subject to start with normal breathing through the mouthpiece. 
 Instruct the subject to take a deep inhale, ﬁlling their lungs completely. 
 Immediately after inhalation, instruct the subject to exhale as forcefully and fully as  

 possible. Encourage them to continue exhaling until they cannot push out any more  
 air. 
 Repeat the test THREE times. 
5. Data Recording and Review 
 After the completion of each test, review the spirometer display for the quality of the  
 blow. 
o b) If the eƯort is insuƯicient, press "Reject" and repeat the test. 
o c) If the eƯort is suƯicient, proceed to the next step. 
 After all tests are completed, select "Results" to review the data from all tests  
 performed. 
 Record ALL value on the device to the excel sheet 
 If further testing is required, select "Perform Another Test" to repeat the process. 
 If testing is complete, select "Done" to ﬁnalize the session. 
6. After data collection  
1. Give the device to the subject  
 Instructed them to start at level “4” on the ﬁrst week 
 Make sure both inhale and exhale ring on the same level 
 Record the on their device log.  
2. Give them the device log and the instruction sheet.
