How can a technologist evaluate the pressure delivered by a malfunctioning CPAP machine?

Using a water column manometer is an effective method for evaluating the pressure delivered by a malfunctioning CPAP machine. The water column manometer consists of a tube filled with water, where the height of the water column correlates to the pressure in centimeters of water (cmH2O). By connecting the manometer to the CPAP machine's airflow output, the technologist can accurately measure the pressure being provided by the device.

This method is particularly beneficial because it provides a direct measurement of the airway pressure during operation, allowing for precise evaluations of the CPAP machine's functionality. Understanding the normal operating range of CPAP pressures is vital for ensuring patient safety and comfort, making this approach critical for addressing any potential malfunctions that can impede effective therapy.

While contacting the manufacturer may be necessary for advanced problems or to obtain technical support, it doesn't provide immediate information on the functioning pressure. Checking the power supply could be part of troubleshooting but does not measure pressure directly. Using a manometer is a valid alternative; however, for precise measurement in a clinical setting, a water column manometer is typically preferred.
