“…This positive pressure helps to keep the airways open and improves oxygenation during ventilation [13][14][15]. In the BiPAP configuration, the high pressure level is called inspiratory positive air pressure (IPAP) [16][17][18]. The lower level is called expiratory positive airway pressure (EPAP).…”

Recently, the incidence of, and interest in, respiratory diseases has been amplified by severe acute respiratory syndrome coronavirus (SARS-CoV-2) and other respiratory diseases with a high prevalence. Most of these diseases require mechanical ventilation for homecare and clinical therapy. Herein, we propose a portable and non-invasive mechanical fan (NIV) for home and clinical applications. The NIV’s core is a turbine for airflow generation, which can provide and monitor a positive two-level pressure of up to approximately 500 lpm at 50 cmH2O according to the inspiration/expiration phase. After calibration, the proposed NIV can precisely set the airflow with a pressure between 4 cmH2O and 20 cmH2O, providing a versatile device that can be used for continuous positive airway pressure (CPAP) or bilevel positive airway pressure (BiPAP). The airflow is generated by a turbine monitored using a mass flow sensor. The whole NIV is monitored with a 16 MHz clock microcontroller. An analog-to-digital converter is used as the input for analog signals, while a digital-to-analog converter is used to drive the turbine. I2C protocol signals are used to manage the display. Moreover, a Wi-Fi system is interfaced for the transmission/reception of clinical and technical information via a smartphone, achieving a remote-controlled NIV.

“…When choosing a ventilator for a home program, there are differences in the details within each model about triggering, pressurization, or autotitration algorithms that are ignored, but these differences are important and may contribute to drawbacks that may occur in individual patients. In their review, Luján and Lalmolda [ 7 ] describe the systems that popular models of ventilators use for triggering EPAP titration and the response to unintentional leaks.…”
