A ventilator is a machine that provides mechanical ventilation by moving breathable air into and out of the lungs, to deliver breaths to a patient who is physically unable to breathe, or breathing insufficiently. Modern ventilators are computerized microprocessor-controlled machines, but patients can also be ventilated with a simple, hand-operated bag valve mask. Ventilators are chiefly used in intensive-care medicine, home care, and emergency medicine (as standalone units) and in anesthesiology (as a component of an anesthesia machine).
COVID-19 Patients becomes seriously ill and has difficulty breathing, according to the World Health Organization. That’s because lungs are the main battleground in COVID-19 infections, which can cripple breathing functions.Ventilators gently pump air through a breathing tube into the patient’s lungs and allow the patient to exhale. This gives patients oxygen and removes carbon dioxide, which can damage the patient’s organs if not expelled.
In some cases, air with higher oxygen content is used. Settings are tailored to patient needs.Patients can’t talk because the tube passes through their vocal cords. The tubes can be uncomfortable and it takes time to get used to them, according to AgingCare.Ventilator operation is closely monitored to maintain pressure and expiration levels.
• Provision to set tidal volume and control the output
• Optional pressure support mode – The user can set inspiratory pressure and expiratory pressure modes
• Auto sense – to apply the inspiratory or expiratory pressure as per the patient breathing
• Failsafe mode
• Plateau pressure – System will adapt to achieve volume and be limited to 35 cmH2O
• Peak pressure – System will adapt to suit for not more than 2cmH2O (> plateau pressure)
• Mechanical Failsafe Valve – System shall have mechanical failsafe valve that opens at 40 cmH2O
• Positive End Expiratory Pressure (PEEP) – Range 5 to 25 cm H2O adjustable in 5 cmH2O increment
• Inspiratory: Expiratory ratio – Adjustable in the range 1.0 to 3.0
• Respiratory Rate (/Min) – Range of 10 to 30 breaths in increments of 2 (can be set by the user)
• Tidal Volume (Vt) – Variable Range 250 to 1500 ml in steps of 50ml
• The system shall have provision to key in body weight and have automatically set the volume to suit the body weight.
