How to coach a patient to perform spirometry
The typical spirometry exam is a three-phased process – each with their own coaching techniques to help patients produce an effective test.
- Phase 1
In the first phase, the goal is to instruct the patient on the proper techniques to apply their mouth to the spirometry mouthpiece. Best results are achieved when the patient takes a deep, deep breath, placing the mouthpiece between their teeth, and sealing the mouthpiece with their lips. - Phase 2
The second phase is the BLAST. This is when the patient will blow out as hard and as fast as possible. Coaching a patient in this phase is best achieved by developing a rapport with them prior to the exam, as the tester will learn which level of coaching is best for that individual patient. - Phase 3
The final phase is the remaining 5 to 6 seconds of exhalation. In this phase, you’ll quietly encourage the patient to “keep blowing” to complete the exhalation.
