ABSTRACT

Lung atelectasis caused by shallow breathing patterns is common after cardiac, thoracic and upper abdominal surgeries. A common method used to address this problem is to encourage patients to perform breathing exercises using incentive spirometers in the postoperative period. However, to be effective, this procedure must be repeated regularly so that adequate lung volumes can be maintained to prevent atelectasis. Current models of single-use, low-cost incentive spirometers do not have features that can track and store data on breathing exercises. This makes it difficult to monitor patients’ breathing exercises effectively. We present here a device designed to be interfaced with the Spiro-ball incentive spirometer and programmed to monitor the incentive spirometry performance. Laboratory based validation performed indicate that there were no significant differences between the value obtained from the device and manual reading; p-value > 0.05 and root-mean-square error (RMSE) is 3.882. The device was able to retrieve and display pertinent data on incentive spirometry performance. It was also able to correctly track and register random sets of inspiration data through different dates and timelines. Being a separate entity which is reusable, it does not add to the cost of the single-use incentive spirometer.

ABSTRAK

Atelektasis paru-paru yang berpunca daripada pernafasan yang cetek adalah satu kebiasaan selepas pembedahan jantung, toraks dan abdomen bahagian atas. Kebiasaannya, kaedah yang digunakan untuk mengatasi masalah ini adalah menggalakkan pesakit menjalankan latihan pernafasan menggunakan spirometer insentif dalam tempoh pasca pembedahan. Walau bagaimanapun, untuk ia menjadi efektif, prosedur in perlu diulang secara berterusan supaya isi padu paru-paru yang mencukupi dapat dikekalkan untuk mengelakkan atelektasis paru-paru terjadi. Model semasa bagi spirometer insentif adalah sekali guna dan kos rendah serta tidak mempunyai ciri-ciri mengesan dan merekod data untuk latihan pernafasan. Hal ini menyukarkan proses pemantauan latihan pernafasan yang dilakukan oleh pesakit secara efektif. Kajian ini membentangkan alat yang direka untuk diaplikasikan bersama Spiro-ball spirometer insentif dan diprogramkan untuk memantau prestasi insentif spirometri. Validasi menerusi makmal yang dijalankan menunjukkan bahawa tiada perbezaan ketara antara nilai yang diperoleh daripada alat ini dan bacaan secara manual; nilai p lebih besar daripada 0.05 dan punca min ralat kuasa dua (RMSE) adalah 3.882. Alat ini berupaya untuk mendapatkan kembali dan memaparkan data prestasi insentif spirometri. Ia juga mampu mengesan dan menyimpan set data yang rawak melalui tarikh dan masa yang berbeza. Alat ini merupakan entiti yang berasingan daripada spirometer insentif, oleh yang demikian ia tidak menambah kos asal spirometer insentif sekali guna.
