“…As oxygen is considered as a drug, then required cautions with reference to pharmacotherapy principles should be used in its administration (7) and, as with any other drugs, its indications and complications, care practices in administration, and monitoring should receive much attention (8).…”

Background: The main problem of preterm infants is lung function disorder and disordered oxygenation due to an immature respiratory tract, therefore, appropriate performance of nurses in oxygen therapy is very important. Objectives: The aim of this study was to investigate nurses' performance during oxygen therapy for hospitalized infants at the neonatal intensive care unit (NICU). Patients and Methods:In this descriptive, cross-sectional study, 110 nurses working at the NICU of teaching hospitals affiliated with the Isfahan University of Medical Sciences were enrolled by the census. Data were gathered from a questionnaire on demographic characteristics and a checklist for observational assessment of nurses' performance. Data analysis was done with the SPSS 20 software. Results: Of the nurses, 39.1% had favorable performance. Furthermore, Spearman's correlation coefficient indicated that age and nurse's performance were directly and significantly correlated, yet education level and work shift types were not correlated with performance. Conclusions: Since oxygen is frequently administered at the NICU, holding in-service training courses for improving nurse's performance and preventing long-term complications due to oxygen administration seem necessary.

“…The main purpose of oxygen therapy in premature infants is not only to support life, but to also stimulate lung development. The procedure supplies a mixture of oxygen and pure pressurized medical-grade air via ventilation machine in order to maintain the SpO 2 level between 90% and 95% [2,3]. Fraction of inspired oxygen (FiO 2 ) is a parameter that indicates the percentage of oxygen content in air, and it has a value between 21% and 100% [4].…”

“…To provide oxygen therapy, registered nurses are responsible for adjusting FiO 2 based on the patient's current SpO 2 level. Although we have limited knowledge as to how much oxygen these patients actually need, or how much oxygen is safe to give, it is in the best interest of the patient to adjust the FiO 2 level in as close to real time as possible [1][2][3]5]. Lim et al [6] compared the effectiveness of oxygen therapy in preterm infants via manual FiO 2 adjustment against automatic FiO 2 adjustment.…”

Premature babies of less than 37 weeks gestation might require oxygen therapy as an integral part of treatment and respiratory support. Because of their under-developed lungs, these socalled "preemies" might contract respiratory distress syndrome (RDS). To treat RDS, neonatal oxygen therapy is administered, where controlled oxygen gas is measured as a fraction of inspired oxygen (FiO 2 ). However, exposure to high oxygen content during long treatment could cause oxygen intoxication, which might cause permanent blindness due to retinopathy of prematurity (ROP), whereas insufficient oxygen exposure could cause severe hypoxia. A doctor would use oxygen saturation (SpO 2 ) data and prescribe a dose of FiO 2 to maintain SpO 2 within a suitable range. One objective is to maintain SpO 2 within the acceptable range using FiO 2 that is as low as possible. Adjustment of FiO 2 would normally be done by nurses every 15 to 30 minutes, which might not be safe in many situations. An error in FiO 2 adjustment during a manual procedure could be as large as +/-2.5%. This paper presents a system that can determine an FiO 2 value suitable to the current SpO 2 and that automatically adjusts FiO 2 with an error clearance of +/-0.25%.

“…However, using an embedded system in medical devices still requires a great deal of tests and clinical approvals to ensure that the device is fully reliable and capable of functioning for extended periods of time without any failure. This research is to develop such an embedded system that can control medical gas mixture proportion (Air and Oxygen) so called FiO2, which has strong effect on Peripheral capillary oxygen saturation (SpO2) in human respiratory system [2].…”

“…However, optimal strategies for oxygen therapy in preterm infants still remain controversial. Balancing levels of FiO2 to stimulate lung functions and maintain adequate tissue oxygenation while avoiding oxygen toxicity is quite a challenge [2]. During oxygen therapy, control mixture gas of medical air and oxygen is supplied to infants into their noses via nasal vented mask.…”

Pre-term infants -less than 37 weeks gestational age --usually had immature lungs' development, which resulted of poor oxygen saturation in red blood cells. A blood oxygen saturation level was measured in percent of Peripheral capillary oxygen saturation (SpO2). Medical doctors needed to order an oxygen therapy to maintain SpO2 of the infants between 90-95% while SpO2 of normal infants is 99-100%. Oxygen therapy was a procedure to stimulate lung functions and to maintain life. A registered nurse (RN) was responsible for adjusting levels of a fractional of inspired oxygen (FiO2) from 21% to 100% which was a proportion of oxygen gas provided to the infants periodically. In real situation, the adjustment could only be made as often as every 20-30 minutes, which might not be adequate. This caused ineffectiveness of an oxygen therapy and result in a longer hospital stay. A critical error of this adjustment could also cause blindness due to oxygen toxicity or dead due to hypoxia. This research was to develop a reliable embedded system that allowed automatically control of FiO2 according to an order of SpO2 by medical doctors. As a result, risks of oxygen toxicity and hypoxia could be minimized. The system also allowed medical doctors to use recorded data for future care planning in oxygen therapy.
