Study Notes
Incentive Spirometry Overview
- Incentive spirometers, or sustained maximal inspiration devices (SMIs), improve pulmonary ventilation and combat anesthesia or hypoventilation effects.
- They help loosen respiratory secretions, facilitate gas exchange, and expand collapsed alveoli.
Functionality
- Mimics natural sighing or yawning by encouraging long, slow, deep breaths.
- Two main types:
- Flow-oriented Spirometer: Features clear chambers with movable colored balls/disks; elevation indicates airflow but does not measure specific volume.
- Volume-oriented Spirometer: Measures inhalation volume with a piston-like plate that rises as the client inhales, displaying the achieved volume on markings.
Client Positioning
- Optimal position for use is upright, whether sitting in bed or a chair, to maximize ventilation.
Client Instructions
- Ensure the spirometer is held upright; tilt may hinder flow-oriented devices and malfunction volume-oriented devices.
- Begin with normal exhalation before sealing lips around the mouthpiece and inhaling slowly and deeply.
- Initial breath-holding should be for 2 seconds, gradually increasing to 6 seconds for optimal elevation of balls or cylinder.
- Emphasize slow intake over brisk breaths to ensure greater lung expansion.
- Sustained elevation of the indicator ensures adequate ventilation of alveoli.
Additional Tips
- Use a nose clip if difficulty breathing through the mouth occurs.
- After taking in a deep breath, exhale normally, followed by coughing to help clear secretions.
- Rest between uses with several normal breaths before repeating the procedure.
- Aim for repetitions of the exercises several times, ideally four to five times per hour, to practice inspiratory volume and prevent atelectasis.
- Clean the mouthpiece with water and shake dry after each use to maintain hygiene.
