The prehospital provider faces many challenges on scene, with one of those being, identifying the underlying cause of patient presentations. In CHF it is notoriously difficult to drill down to the exact cause of the patients chief complaint. Indeed, T A. Williams et al, found that Paramedics have just a 29% sensitivity to correctly diagnosing CHF in the field.
There are some ways to assist in identifying true CHF in the prehospital space. A combination and understanding of these tips will aid your practice and benefit your patients.
1. Pre hospital ultrasound and B-Lines. While ultrasound in the EMS space is nascent, its definitely coming. This website is a great resource for learning about Ultrasound.
2. S3 Heart sound. Sounds intimidating doesn't it? Heart sounds have always been something to avoid in EMS. But the S3 sound is the easiest to learn and will help you in not only Dx your patient, but help you better understand what's going on. It will also give you some serious credibility in the ED when you say "Patient has audible S3 on auscultation that supports the Hx of CHF"
