I recently had a trach patient who was on the blender receiving up to 90% oxygen, with sats in mid 80's, had pneumonia, COPD and many other diagnoses.( I understand the whole oxygen issue with COPD patients.) We were suctioning her as needed and still she was having a hard time breathing, very anxious too. (I probably would be too if I couldn't get my breath.) Of course I had called the doc on call and he had assessed her (she eventually moved to the ICU from telemetry/step-down unit), ordered blood gas and chest xray that revealed total white-out in her lungs from pneumonia. We had bagged her (with help of more experienced nurses on floor), but evidently the cuff was deflated and the RT got really mad about this. Why exactly does the cuff need to be inflated with bagging? I don't really understand totally, so patient doesn't aspirate, what else? The patient transferred to ICU and put on vent. Anyway, respiratory issues are scary and I plan on following a RT to learn more. Thanks for any input.
