Intelligent ventilators crucial last mile technology in saving patient lives: Devang Lakhia, Hamilton India


    During the peak of Covid-19’s second wave, health systems across the nation witnessed their critical resources rapidly getting overwhelmed by an increasing number of patients. It threatened to overwhelm medical infrastructure at the regional level, causing spikes in mortality rates. Within the medical infrastructure, there are critical technologies that are generally available, but simply do not exist in a high enough density to handle the excessive volume of patients associated with pandemics. In the 21st Century, pandemics can be dealt with differently than they have historically been with advanced medicine and technology at its side. The biggest modern weapon we now have at our disposal is technology. Smart technology when widely adopted for healthcare has the potential to bring a paradigm shift to present-day healthcare

    In an exclusive conversation with Financial Express Online, CEO of Hamilton India, Devang Lakhia talked about how artificial intelligence is helping India fight the healthcare crisis.

    Explain the concept of smart/intelligent ventilation solutions.

    Intelligent Ventilation solutions simply put can be called bedside assistants that function using physiologic data from the patient and clinician-set targets to regulate CO2 elimination and oxygenation for both passive and active patients. It replicates the mechanism of human breathing to increase the efficacy of oxygen absorption.  This increases the potency of treating mechanically ventilated patients with different conditions and levels of severity. Intelligent ventilators using selected driving pressure, mechanical power and tidal volume deliver individualized lung treatment. Using simplified settings, caregivers can control critical parameters and make a wide range of adjustments depending on the clinical condition of the patient.

    An intelligent ventilator studies a patient’s condition to suggest optimal clinical targets to caregivers. This allows them to move away from the Magic Value parameters used as general settings for most patients on ventilation and instead focus on calibrating other tools employed to keep a patient alive in an intensive care unit. This individualization of lung treatment ensures lung protection of the highest grade to patients against prolonged use of artificial mechanisms to support breathing. Intelligent ventilators also serve one mode of ventilation for both passive and active patients. Healthcare workers by keeping an eye on both hypoxemia and hyperoxemia conditions of patients can adjust settings to avoid both risks.

    The Hamilton Adaptive Supportive Ventilation (ASV) is highly advanced and automatically synchronizes the ventilator with the patient’s breathing mechanics, applying lung protection strategies to minimize complications. The ASV mode has been used in intensive care units since 1998 and has proven itself well. In many settings, it is used for adult and pediatric patients as a standard regimen from intubation to extubation.
