Has anyone here used TGI or gas insufflation on a ventilated patient for assisting in the removal of excessively high persistent CO2? Do you have a good technique or premade system that you use?
I have used this technique only a few times... . However, we do not have any commercially available devices. We just used a elbow connector with a succion port, in which we insert a 8 Fr succion catheter to give from 1 to 6 lpm O2. Only once I got interesting results (but it was kind of unexpected: the PaO2 got better, but not the PaCO2...). Since the arrival of HFVO for adult (Sensormedic 3100-B), we just but these people (that meet the criterias usually) on it, with a higher bias flow, and if needed, we could creat a leak at the endotracheal tube cuff to better ventilation. Hope it is relevant info for you!
Respironics now has a commercially available TTAV system (Cadence System). It includes everything from Tracheostomy cannula's, humidifier, heated wire circuit, blender etc.
