Electronic cuff pressure gauge is designed to monitor cuff pressure for trachea cannula, tracheotomy tube, or duplex cavity bronchial cannula with high-capacity and low-pressure cuffs. It provides both real-time monitoring and digital display. Alarms will be generated when the lower or upper limit of cuff pressure is exceeded, thus reducing potential risks to patients. No human intervention is required as long as the cuff pressure is in its safety range, which helps reduce workload of clinical medical staff.
In General, the pressure inside the cuff should be maintained in the range of 20~30cmH2O. A too high pressure would cause ischemic injury to airway wall mucosa, and a too low pressure would negate the ability of the cuff to prevent secretion from entering the pulmonary bronchi and may consequently cause VAP (ventilator-associated pneumonia). It has been proven in clinical applications that continuous cuff pressure monitoring can effectively reduce the incidence of VAP.
Bosch pressure sensors provide a response time as short as 1ms and ensure accurate pressure measurement; Digital display function is used in place of dial indicators in traditional pressure gauges for easier observation.
Equipped with low-power PIC microprocessors, the device can continuously work for 30 days; the safety pressure range is set as 22~30cmH2O. Any pressure out of this range will trigger both buzzer and flashing light alarms immediately.
Continuous monitoring protects patient’s safety with real-time and reduces the incidence of VAP. Enhanced sealing is provided for the gauge port to eliminate the common problem of air leakage in traditional pressure gauges.
