Being aim at designing a system controller used in the Noninvasive Bidirectional Positive Airway Pressure Ventilation (N-Bi-PAPV) and advancing this medical device to serve the respiratory patients who suffer from the OSAHS, COPD and etc, by using an embed ARM Microcomputer LM3S9B92, the system controller including its circuit diagram and embed software was designed in accordance with the request of Bi-PAP medical ventilator. And the ventilators critical parameters were clearly defined and ranged for this system. After testing in a spontaneously breathing simulator, this system controller may be used to control the ventilator performing function well.

This narrative describes the experiences of an inner city respiratory unit that was transformed to treat COVID-19 patients with continuous positive airway pressure (CPAP) ventilation who were not scheduled for any further escalation in treatment. The high mortality rate and unconventional way of dying led to the creation of local guidance for removing assisted ventilation when the treatment ceased to be effective. We reflect on the specific challenges that caring for these patients holistically has presented and how we have learnt to deliver good palliative care in a unique set of circumstances. We also consider the impact of the pandemic on our team and how the development of a multidisciplinary support system has improved team dynamics and ultimately patient care.
