Pulmonary embolisms don’t always announce themselves... sometimes they ambush. One minute your patient is walking with physical therapy, the next they’re hypotensive, hypoxic, and coding. This re-released early episode dives deep into why PE patients can look deceptively stable… right up until they aren’t.In this episode, I revisit one of my earliest case-based teachings on pulmonary embolism, updated with an added segment on vasopressin use in obstructive shock from PE. Through real bedside stories from my time as a rapid response and ER nurse, we break down the physiology behind PE-related collapse, why intubation isn’t always the answer, and how to think through management when the right ventricle is failing in front of you. This is a sobering but essential refresher on one of the most dangerous diagnoses we encounter.Topics discussed in this episode:Why pulmonary embolism is a common cause of in-hospital cardiac arrest (even if it’s not common overall)Classic and subtle PE presentations and why they’re often missedA real-time rapid response case: stable to crashing in minutesRisk factors for PE and the anticoagulation double-edged swordObstructive shock explained: what’s actually killing the patientRight ventricular failure, septal bowing, and the spiral of deathWhy intubation can worsen outcomes in massive PEVasopressors in PE: norepinephrine, epinephrine, and vasopressinThe unique benefits of vasopressin in obstructive shockThrombolysis vs. thrombectomy: when TPA helps — and when it’s deadlyBedside echo findings that point to massive PEWhy PE patients can crash during transport (and what to always bring)Nursing vigilance, rapid escalation, and activating help earlyWhen perfect care still isn’t enough and the heart of nursing in end-of-life momentsMentioned in this episode:CONNECT 📸 Connect on Instagram: https://www.instagram.com/therapidresponsern/ 📚 Check out my course: https://www.rapidresponseandrescue.com/learnmore 🧑‍💻Check out my website: https://www.rapidresponseandrescue.com/ 📬 Subscribe to my newsletter: https://www.rapidresponseandrescue.com/login 🎁 Affiliation and discounts: https://www.rapidresponseandrescue.com/therapidresponsern ✅ Earn CE’s for listening to podcasts through RNegade: https://rnegade.thinkific.com/?ref=d9d541 SAY THANKS 💜Leave a review on Apple Podcasts: https://podcasts.apple.com/ca/podcast/rapid-response-rn/id1535997752 💚Leave a rating on Spotify: https://open.spotify.com/show/55LQqeDg6XFeixvZLEp4xE ⏱️ To get the FREE Rapid Response RN Assessment Guide and the coupon code for $10 off the cost of the course, message Sarah on Instagram @TheRapidResponseRN and type the word PODCAST!
