Defination and Purpose[edit | edit source]
The purpose of incentive spirometry is to facilitate a sustained slow deep breath. Incentive spirometry is designed to mimic natural sighing by encouraging patients to take slow, deep breaths. Incentive spirometry is performed using devices which provide visual cues to the patients that the desired flow or volume has been achieved. The basis of incentive spirometry involves having the patient take a sustained, maximal inspiration (SMI). An SMI is a slow, deep inspiration from the Functional Residual Capacity up to the total lung capacity, followed by ≥5 seconds breath hold.
An incentive spirometer is a medical device that facilitate SMI with incorporated visual indicators of performance(inspiratory effort) in order to aid the therapist in coaching the patient to optimal performance and likewise patients uses this visual feedback to monitor their own efforts. The device gives the individual visual feedback regarding flow and volume and also prevent and reverse atelectasis when used appropriately and regularly.[1] The visual dimension of the therapy serves as a motivation or goal for the patient to try to meet by repeating the maximal effort frequently.
Guideline on appropriate use[edit | edit source]
- Therapist demonstrates using a separate device and provides information sheet regarding technique, prescription of use and cleaning advice based on manufacturers instructions.
- Patient should be in a relaxed position suitable for deep breathing (e.g. sitting upright in a chair or side lying if extra volume is required in one lung due to ventilation perfusion matching).
- Patient creates a tight seal around the mouthpiece and inhales deeply and slowly. The patient watches the flow meter for visual feedback. If possible the patient sustains the inhalation to create an end-inspiratory hold. Ideally, the inhalation is sustained for 4-5 seconds.
- Patient relaxes seal around the mouthpiece and exhales; normal breathing is resumed with relaxed shoulder girdle.
Further pointers:
- Advise patient to take approximately ten incentive spirometry breaths per waking hour (use clinical reasoning to prescribe using Frequency, Intensity, Time and Type principles).
- Patients with an oxygen requirement can use the device with a nasal cannula or a device, which entrains oxygen.
- Deep breathing offers a similar effect. However, using an incentive device as feedback may create greater inhaled volumes, greater control of flow and more motivation to participate in therapy.

Indications[3][edit | edit source]
- Pre-operative screening of patients at risk of postoperative complications to obtain a baseline of their inspiratory flow and volume
- Presence of pulmonary atelectasis
- Conditions predisposing to atelectasis such as:
- Restrictive lung disease associated with a dysfunctional diaphragm or involving respiratory musculature
- Patients with inspiratory capacity less than 2.5 litres
- Patients with neuromuscular disease or spinal cord injury
Contraindications [6][7][edit | edit source]
- Patients who cannot use the device appropriately or require supervision at all times
- Patients who are noncompliant or do not understand or demonstrate proper use of the device
- Very young patients or paediatrics with developmental delay
- Hyperventilation
- Hypoxaemia secondary to interruption of oxygen therapy
- Fatigue
- Patients unable to take deep breathe effectively due to pain, diaphragmatic dysfunction, or opiate analgesia.
- Patients who are heavily sedated or comatose
- The device is not suitable for people with severe dyspnoea.
Precautions[8][5][edit | edit source]
- The technique is inappropriate as the sole treatment for major lung collapse or consolidation.
- Hyperventilation may result from improper technique.
- There is potential for barotrauma in emphysematous lungs.
- Discomfort may occur secondary to uncontrolled pain.
- Development of bronchospasm may occur in susceptible patients. Close monitoring of patients with hyperreactive airways should be maintained.
