BACKGROUND: In the neonatal population, it is important to closely monitor and limit the suction pressure being delivered to the patient during endotracheal suctioning. With the Ohio Digital suction regulator, pressures are limited to a max pressure of 100 mmHg to promote improved patient safety in the neonatal population. We tested the hypothesis that there was no difference in set versus measured pressure with the Ohio Analog, Ohio Digital, and Ohmeda Analog Suction regulators at set pressures under 100 mmHg when setting pressure properly via a tubing occlusion method. METHODS: Set and measured pressure were compared for the Ohio Analog, Ohio Digital, and Ohmeda Analog suction regulators tested. Pressure was set at four different pressure range increments from 40- 100 mmHg by occluding the suction tubing for twenty seconds. Delivered pressure was recorded for both the suction regulator reading and independent pressure calibration meter. The independent monitor was calibrated prior to testing. Three measurements were recorded for each testing condition. Statistical Analysis was performed using ANOVA with post hoc analysis in Sigmaplot version 11. The mean pressure was reported for each testing condition. RESULTS: See Chart CONCLUSION: The Ohmeda Digital Suction Manometer has a set pop off of 100 mmHg to decrease risk of delivering high suction pressure to neonates. When setting pressure using the tubing occlusion method, there was no statistical difference in delivered suction pressure when comparing the three suction regulators. Using any of the three devices will give the patient safe suction pressures when set appropriately. Sponsored Research - None Comparison of Pressure in mmHg
