Ep.33 - The Ultimate Compressor
In this episode, Dave shares the importance of practicing quality CPR with the goal of being the 'ultimate compressor'. Also In This Episode: Patient case which deteriorates to cardiac arrest- AHA/ILCOR ECC guidelines to begin immediate chest compressions and application of the cardiac monitor with an attempt at defibrillation. Work as a team on the choreography of resuscitation. Ensuring no one provider has a cognitive overload and is able to focus on a specific assigned task. Ensure the provider who is performing the skill of chest compressions is able to focus on the appropriate rate, minimizing pauses, and allowing for complete chest recoil. CPP - Coronary Perfusion Pressure is the key to providing the cardiomyocytes with the sugar, water, oxygen they need to survive by perfusing the coronary ostia and building CPP. Post ROSC care should include maintaining a systolic blood pressure of at least 90mmhg, 02 sats between 94-99%, patient normothermia, 12 lead ECG interpretation and finally working with other health care providers on a coordinated transfer of care.

Ep.19 - Current ECG + Master Your Medics | TCA Overdose Case Study
On this episode, Current ECG teams up with Master Your Medics to present a TCA Overdose case! Dave discusses the pathophysiology behind sodium channel blocking medications and how they affect cardiac depolarization at the cellular level. This is important because it affects how we interpret the ECG. Cardiac toxicity can develop quickly in TCA overdose, so get an ECG early in the clinical course if suspecting the diagnosis. Dave also discusses how sodium bicarbonate works to alter the patients ph level as well as competitively binding to sodium channel receptors helping to reverse the acidosis and TCA availability in the blood. Treatment options include: Oxygen Sodium bicarbonate for a QRS complex wider than 100ms. Assisted ventilations via BVM with potential for early intubation consideration which will help to blow off C02 0.9% Normal Saline What are some signs of TCA Overdose on the ECG? Sinus Tachycardia – most frequent dysrhythmia Widening of the QRS complex Prolongation of the PR or QT interval Right bundle branch block Non-specific intraventricular conduction delay (IVCD) Brugada pattern Wide-complex tachycardia (not ventricular tachycardia) Ventricular tachycardia / fibrillation How wide is too wide? A QRS duration >100ms is predictive of seizures and QRS >160ms is highly likely to experience a ventricular dysthymia. The ECG from our patient had a QRS of 144! . Check out Master Your Medics: .

Ep.13 - Don't Miss The QT Interval!
On this episode Dave talks about how the QT interval is a big deal and how we should be looking at it each time we perform an ECG. QT Interval - The time from the beginning of the Q wave to the end of the T wave. Also In This Episode Please start looking at the QTc as part of your regular ECG interpretation Torsades de Pointes is a specific form of 'Polymorphic Ventricular Tachycardia' caused by a 'Long QT'. Watch out and prepare! QT little 'c' which stands for (corrected). What it is correcting for? It's correcting for 'RATE' and averaging everything to 60 beats per minute. QTc > 0.50 sec = a clinically significant prolonged QT interval and you need to tell somebody about it!! Patients at higher risk - Methadone and medications of the Mycin family are notorious for prolonging the QT interval to name just a very few. Brush up on all the other medications that prolong the QT. Take a closer look at the QTc in patients who are elderly and perhaps suffer from chronic renal insufficiency...they are higher risk patients for a prolonged QT. And don't forget...If you encounter a patient in Torsades. Once you fix the rhythm, immediately as yourself...Hmm why did this patient have a prolonged QT interval??? So it doesn't happen again.
