Bottom Line: Oxygen is a lifesaving medication that should be offered with an administration to a patient who suffers from oxygen deficiency to avoid toxic effects of excessive oxygen supplement as well as to minimize the exposure to hypoxaemia.In this work, a prototype model for a Portable Automated Oxygen Delivery System that consists of two subsystems: an Oxygen Reader Subsystem and an Automated Adjustment Oxygen Delivery Subsystem, both communicating wirelessly, has been developed.The system promises significant benefits in improving the life quality of hypoxaemic patients as well as healthcare service for oxygen delivery administration.

ABSTRACT
Oxygen is a lifesaving medication that should be offered with an administration to a patient who suffers from oxygen deficiency to avoid toxic effects of excessive oxygen supplement as well as to minimize the exposure to hypoxaemia. This work aims to automate the process of administering oxygen delivery in order to extend the continuous oxygen administration process beyond the IC units, reduce the cost of oxygen administration in terms of well-trained health care providers and equipment, prolong the lifetime of oxygen supplement, and help in the process of weaning patient from oxygen. In this work, a prototype model for a Portable Automated Oxygen Delivery System that consists of two subsystems: an Oxygen Reader Subsystem and an Automated Adjustment Oxygen Delivery Subsystem, both communicating wirelessly, has been developed. The system promises significant benefits in improving the life quality of hypoxaemic patients as well as healthcare service for oxygen delivery administration.

Mentions: The raw Red PPG and Infra-red PPG signals were processed using Digital FIR and IIR filters to obtain their AC and the DC components. The filters to extract the AC and DC components of the PPG signal were: (1) Second order, low pass IIR Butterworth filter with cut-off frequency equals to 0.1 Hz for DC tracking, (2) Fourth order, high pass IIR Butterworth filter with stop frequency equals to 0.1 Hz and pass frequency equals to 0.5 Hz for DC removal, and (3) Tenth order, Low pass FIR-Window (Kaiser window with beta = 0.5) filter with cut-off frequency equals to 10 Hz to remove the noise from the AC component. The first filter was used to track the DC component, and the other two filters were used in consequence to obtain the AC component and remove the noise. These filters were designed using filter design tool in Simulink (MATLAB), then the coefficients of these filters were extracted and used with DSP library from STMicroelectronics to implement these filters and acquire the AC and DC components of the Red PPG and Infra-red PPG signals. Designing these filters was conducted while considering the frequency band for the PPG signal, which is between 0.5 and 4.0 Hz (Carr and Brown 1998; MASIMo 2001). The processed PPG signal in the Oxygen Reader Subsystem is shown in Fig. 10.Fig. 10
