So had a patient say in there 60s with CHF. She complained of weakness and her husband mentioned in just a few weeks her legs got so much more swollen. So first we checked the ABCs she was protecting her airway, her breathing was very congested had coughing and heard some crackling, circulation showed normal color and A&O x4. Vitals revealed a HR in 120s and a BP around 90/40, 02 was around 88% which was not normal for her she explained. Her RR was in the 20s temp was 99.1f and BGL was 110. We then did a ECG which was read as sinus tachycardia otherwise WNL. So what we did on this case is I established a line and DIDN'T give fluids just got a line for the ED. I originally started 6lpm NRB which the medic changed to CPAP. No I didn't get a intercept this time because I was already working with a medic this shift. After we spent about 10min on scene we were ready to go and I stayed in the back and just comforted her by letting her talk and just listen. She had a sad story but I got to see her O2 come up and she said this resolved her sob which we weren't informed about on presentation just something mentioned as we were arriving. Anything you would have done differently?
