What is ShiVent?
ShiVent is a low-cost, non-electric and non-invasive ventilator for patients with respiratory difficulties, available at a fraction of the cost of mechanical ventilators. Its simple design enables it to be operated by unspecialised healthcare workers.
The high price and shortage of mechanical ventilator systems in Africa have contributed to the deaths of thousands of patients. ShiVent is designed for under-resourced clinics with unreliable electricity supply and limited access to specialist knowledge.
How does it work?
Energy infrastructure engineer Yusuf Bilesanmi and his team developed ShiVent in response to the strain placed on healthcare systems during the Covid-19 pandemic. Using the principles of Bubble CPAP (Continuous Positive Airway Pressure), the ShiVent blends air with a high-flow oxygen supply using a specifically designed Venturis air blender and delivers this to a patient still able to breathe by themselves. This is critical to the survival of patients experiencing respiratory distress.
The device only requires 150 to 200 cylinders of oxygen a day, at a rate of 5 to 12 litres of oxygen per minute (lpm). The Lagos State government currently uses 400 cylinders of oxygen a day, at 15 lpm.
What is the challenge? What is the solution?
Nigeria has as few as 288 mechanical ventilators serving almost 200 million people. The ShiVent is a simple, low cost ventilatory alternative which does not depend on electricity and is widely replicable.
ShiVent has completed functionality testing at the National Centre for Sports and Exercise and Medicine at Loughborough University and Leicester Royal Infirmary Hospital. It has also undergone preliminary clinical feasibility tests at NIHR Leicester Biomedical Research Centre, Glenfield Hospital. The results demonstrate that the device is indeed functional and meets CPAP requirements set by the Medicines and Health Regulatory Agency in the United Kingdom
