An important anesthesia parameter is monitoring the proper airway pressure in the patient. A Manometer is a standard piece of equipment on all anesthesia machine used to measure this pressure in CMs of H2O. However, the Manometer on an anesthesia machine is not utilized on non-breathing circuits as it is bypassed.
Non rebreathing circuits are used on smaller more fragile patients. There is a higher risk of inadvertent alveoli damage or barotrauma when “bagging” or manually ventilating a patient. There have been cases of pneumothorax. The flush valve on an anesthesia machine will immediately push up oxygen flow to 15L at 50psi into a small non breathing circuit. The new in line manometer gives accurate airway pressure to avoid harmful over inflation, but still ensure adequate ventilation is achieved.
• Works on common non-rebreathing circuits
• Simple to use – detach rebreathing bag and insert Manometer (directions included)
