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.
Kata kunci: Latihan
pernafasan; pengumpulan
data; spirometer insentif
