Sepsis and septic shock start with an infection and the body's dysregulated response to it. Sepsis is life-threatening organ dysfunction, a SOFA rise of 2 points or more from the patient's baseline. Septic shock is sepsis where the pressure and the cells both fail. Recognizing it early starts the one-hour bundle early. We follow sepsis down to the cellular level, then match each bundle step to the part of the blood pressure equation it treats.

The autonomic nervous system controls heart rate, blood pressure, airway size and secretions. It has two branches. The sympathetic branch is fight or flight and releases norepinephrine onto alpha and beta receptors at the organ. The parasympathetic branch is rest and digest and releases acetylcholine onto muscarinic receptors. Every ICU drip works at the transmitter, the receptor or the cell. We follow the signal from the brain to the organ, then tie each receptor to the drips you hang.

How to read an EKG comes down to five steps in the same order on every strip: rate, rhythm, intervals, axis, then ST segments and T waves. The first three steps read time. The last two read voltage and need a 12-lead. At 25 millimeters a second, one small box is 0.04 seconds. We finish by applying all five steps to one 12-lead EKG. RESOURCES FOR THIS EPISODE: Grab the free ECG and ICU Waveforms Cheat Sheet KEY POINTS: Rate: 300 divided by the big boxes between R waves, or 1500 divided by the small boxes when the rate is fast Rhythm: find it by looking at the P waves Spotting atrial fibrillation, atrial flutter, junctional rhythm, PACs and PVCs Intervals: measure the PR, QRS and QT, and correct the QT to the QTc Telling first-degree, Wenckebach, Mobitz II and third-degree block apart Axis from lead I, aVF and lead II Reading ST elevation, STEMI versus non-STEMI and T wave changes A normal EKG: sinus rhythm at 60 to 100, PR 0.12 to 0.2 seconds, and an axis between negative 30 and positive 90 degrees FREE RESOURCES TO HELP YOU ON YOUR CRNA JOURNEY: Transcript Analyzer - See your cumulative, science, and last-60-credit GPAs 9-Step Application Checklist - Work through the CRNA school application process in order CRNA School Database - Search and compare CRNA programs Certification Planner - Build a CCRN, CSC, or CMC study schedule around your shifts Timeline Generator - Build a personalized CRNA application timeline Try The CRNA Club free for seven days - Explore the all-in-one CRNA school application platform.

The coagulation cascade is the chain of clotting factor steps which ends in thrombin. Thrombin cuts fibrinogen into fibrin, the mesh holding a clot together. The extrinsic and intrinsic pathways both meet at factor 10, and the PT and aPTT time how long fibrin takes to form after each pathway starts. We start with a question: why does a patient on Plavix bleed when the platelet count, PT and aPTT are all normal? Then we follow the cell-based model from injury to fibrin, and read each test and each drug against it. RESOURCES FOR THIS EPISODE: Grab the free Anticoagulation Cheat Sheet KEY POINTS: Extrinsic pathway: tissue factor plus factor 7 activates factor 10, and three plus seven equals ten Intrinsic pathway: the order is 12, 11, 9 and 8, which also reaches factor 10 Common pathway: 10, 5, 2 and 1, with factor 13 cross linking the fibrin Platelet adhesion, activation and aggregation, and how aspirin and clopidogrel block them for the 7 to 10 day life of a platelet The cell-based model: initiation, amplification and propagation Why missing factor 8 or 9 causes hemophilia bleeding Antithrombin, protein C and plasmin as the brakes on clotting How the PT, INR and aPTT work, with typical values of PT 9.5 to 12.5 seconds, INR 0.9 to 1.1 and aPTT 25 to 37 seconds Heparin, enoxaparin, HIT and protamine reversal Warfarin, vitamin K and four-factor PCC reversal Direct oral anticoagulants, argatroban and Praxbind FREE RESOURCES TO HELP YOU ON YOUR CRNA JOURNEY: Transcript Analyzer - See your cumulative, science, and last-60-credit GPAs 9-Step Application Checklist - Work through the CRNA school application process in order CRNA School Database - Search and compare CRNA programs Certification Planner - Build a CCRN, CSC, or CMC study schedule around your shifts Timeline Generator - Build a personalized CRNA application timeline Try The CRNA Club free for seven days - Explore the all-in-one CRNA school application platform.

Grab the FREE Types of Shock Comparison Cheat Sheet: https://thecrnaclub.com/free/types-of-shock-comparison-cheat-sheet Try The CRNA Club FREE for 7 days: https://thecrnaclub.com/free-trial The four types of shock are hypovolemic, cardiogenic, distributive and obstructive. MAP roughly equals cardiac output times SVR, and a different piece of that equation breaks in each type. Hypovolemic loses preload, cardiogenic loses pump strength, distributive loses vascular tone, and obstructive blocks filling or forward flow. Cardiac output, filling pressures and SVR show which piece broke. IN THIS EPISODE: How shock starts with oxygen delivery and what happens inside the cell Baroreceptors, alpha-1, beta-1, RAAS and vasopressin as the body's response Hypovolemic shock numbers and the bedside picture Cardiogenic shock, the wedge pressure, right ventricular infarct and treatment Septic, anaphylactic and neurogenic shock as the three distributive types Massive PE, tamponade and tension pneumothorax as obstructive shock Telling the types apart from cardiac output, filling pressures, SVR, wedge and PA diastolic Where to keep learning shock pathophysiology and pharmacology COMMON QUESTIONS: Do all types of shock cause hypotension? Not always. In hypovolemic shock the vessels clamp down, so blood pressure often holds until about 30 percent of blood volume is lost. Heart rate, pulse pressure, lactate and urine output usually change first, so a normal blood pressure does not rule shock out. Is sepsis a type of shock? Septic shock is a type of distributive shock, but sepsis alone is not septic shock. Septic shock means sepsis where a vasopressor is still needed to keep the MAP at 65 or higher after adequate fluids, with a lactate above 2. Nitric oxide relaxes the vessels, so the SVR falls. What type of shock does cardiac tamponade cause? Cardiac tamponade causes obstructive shock. Fluid or blood fills the pericardial sac, pressure rises and chambers barely fill. Cardiac output falls, and CVP, PA diastolic and wedge pressures rise toward one number. Beck's triad is low blood pressure, distended neck veins and muffled heart sounds. Drainage fixes it.

Phenylephrine tightens blood vessels, albuterol opens the airway, and Precedex turns down the sympathetic nervous system. All three drugs send their message through G protein-coupled receptors. Sachi, a practicing CRNA and founder of The CRNA Club, starts with what a receptor is, compares the four major receptor families, and follows the Gq, Gs, and Gi pathways step by step, from the receptor to the second messenger to the effect you see at the bedside.

Ventilator mode names vary, but the reasoning starts with the targeted variable, breath sequence, and the patient's work of breathing.

Hemodynamics makes more sense when pressure, flow, resistance, and oxygen delivery are interpreted together.

Precedex versus propofol is not a one-drug-wins comparison.
