| dc.description.abstract | Mechanical ventilation serves as a lifesaver in the rapidly evolving field of respiratory
disease treatment. However, limitations of existing ventilators, such as high cost and
limited portability, affect the accessibility and affordability of respiratory support in
resource-limited emergency settings. The aim of this paper is to design a low-cost
and portable ventilator machine that overcomes the limitations of ICU ventilators and
other portable ventilators. This proposed solution focuses on affordability, portability,
and versatility, making it suitable to provide lifesaving respiratory support in various
settings. Prior to the design phase, a background study was conducted using the
shadow approach, alongside a literature review to collect relevant data and insights.
The proposed design consists of an ATmega2560 Arduino microcontroller as the main
control board, along with a Honeywell AWM720P1 flow meter, Bosch BMP280 pressure
sensor, SST OXY-LC oxygen sensor, and Max30100 pulse oximetry sensor. This system
offers Assist Control (AC), Synchronized Intermittent Mandatory Ventilation (SIMV),
and Cardiopulmonary Resuscitation (CPR) ventilator modes, as well as adjustable
tidal volume, respiratory rate, positive end-expiratory pressure value, and a pressure
control system with a user-friendly interface. This design includes a standalone feature,
allowing the ventilator to operate in the absence of an external oxygen supply. It also
has an alarm system to alert operators or caretakers about potential issues such as high
pressure, insufficient oxygen levels, low pulse oximetry, power shortages, or abnormal
heart rates. | en_US |
