<p><span style="font-family: Verdana,Arial,Helvetica,sans-serif; font-size: small;"><strong>Introduction:</strong> Transducer calibration is very important for the accurate measurement of pressures during invasive hemodynamic monitoring of patients requiring close observation in the primary care units and in the operating room. <br /> </span><span style="font-family: Verdana,Arial,Helvetica,sans-serif; font-size: small;"><strong>Objective</strong>: To develop and validate a method of calibration of pressure transducers, which is simple, efficient and low-cost. <br /> </span><span style="font-family: Verdana,Arial,Helvetica,sans-serif; font-size: small;"><strong>Methods: </strong> An alternative manometric method, based on Pascal's law, was developed for the calibration of pressure transducers during invasive hemodynamic monitoring performed at the intensive care unit of the cardiovascular surgery department at Hermanos Ameijeiras Clinical-Surgical Hospital. This method was validated by its comparison with the recommended standard in a total of 215 patients who required invasive hemodynamic monitoring between January and June 2015. <br /> </span><span style="font-family: Verdana,Arial,Helvetica,sans-serif; font-size: small;"><strong>Results</strong>: With the alternative manometric method created, the same result was obtained as with the hydraulic method recommended by the literature. <br /> </span><span style="font-family: Verdana,Arial,Helvetica,sans-serif; font-size: small;"><strong>Conclusions:</strong> The alternative method created is accurate, efficient and cost-effective. </span></p>
