The World of Critical Care
The World of Critical Care podcast discusses medical topics in twenty minutes or less for professionals, new and seasoned, and families struggling to understand the care of their family member. Episodes tackle complex topics, helping to inform students, nurses, nurse practitioners, physicians assistants, and physicians alike in furthering their knowledge.
Episodes
The following episode covers the basics of correctly setting up arterial lines, interpreting waveforms, troubleshooting, and removal.

The following episode covers the basics of potassium as an electrolyte in critical care.
Nurse lead spontaneous breathing trials is a common aspect of recovering hearts in the CVICU. But SBT's are common in a wide variety of ICU settings. This episode covers the basics of successful SBT's.
Hypernatremia occurs in up to one fourth of ICU patients. The following episode covers the basics of understanding the critical factors in hypernatremia.

One of the most common lab values I have questions about from new nurses is the SvO2 and how it is used as an approximation for cardiac output. As a followup up to the episode on taking hearts this episode considers one of the most common lab values used in critical care to approximate cardiac output.
Caring for post operative CVOR patients can be one of the most rewarding and challenging shifts for a CVICU/ICU nurse. The following episode covers the basics of pre-operative assessment, intra-operative analysis, and post-operative care. By no means comprehensive, the episode seeks to cover the basics and provide a steady foundation for growth.
The following episode covers the basics of hyponatremia. This episode is a bit longer than most but the prevalence of hyponatremia in critical care warrants a slightly longer conversation.

The following episode covers the action potential in a neuron. Specific attention is paid to the critical role of electrochemical gradients and concentration gradients established by sodium and potassium. This episode also serves as an overview of the action potential generally.
The following episode provides part one of sodium physiology examining how the body regulates sodium levels via the renin-angiotensin-aldosterone system.
One of my favorite lectures on this topic:

The following episode introduces the electrolyte sodium. Lab collection, general overview of physiological processes, and defining critical terms. The next episode will cover in depth the physiological processes dependent upon sodium.
The following episode covers the basics of anti-platelet therapy.
Massive transfusion can be a highly stressful event in the ICU. The following episode covers the basics of carrying out massive transfusion protocol.

The Burden is a documentary series that takes listeners into the hidden places where justice is done (and undone). It dives deep into the lives of heroes and villains. And it focuses a spotlight on those who triumph even when the odds are against them. Season 5 - The Burden: Death & Deceit in Alliance On April Fools Day 1999, 26-year-old Yvonne Layne was found murdered in her Alliance, Ohio home. David Thorne, her ex-boyfriend and father of one of her children, was instantly a suspect. Another young man admitted to the murder, and David breathed a sigh of relief, until the confessed murderer fingered David; “He paid me to do it.” David was sentenced to life without parole. Two decades later, Pulitzer winner and podcast host, Maggie Freleng (Bone Valley Season 3: Graves County, Wrongful Conviction, Suave) launched a “live” investigation into David's conviction alongside Jason Baldwin (himself wrongfully convicted as a member of the West Memphis Three). Maggie had come to believe that the entire investigation of David was botched by the tiny local police department, or worse, covered up the real killer. Was Maggie correct? Was David’s claim of innocence credible? In Death and Deceit in Alliance, Maggie recounts the case that launched her career, and ultimately, “broke” her.” The results will shock the listener and reduce Maggie to tears and self-doubt. This is not your typical wrongful conviction story. In fact, it turns the genre on its head. It asks the question: What if our champions are foolish? Season 4 - The Burden: Get the Money and Run “Trying to murder my father, this was the thing that put me on the path.” That’s Joe Loya and that path was bank robbery. Bank, bank, bank, bank, bank. In season 4 of The Burden: Get the Money and Run, we hear from Joe who was once the most prolific bank robber in Southern California, and beyond. He used disguises, body doubles, proxies. He leaped over counters, grabbed the money and ran. Even as the FBI was closing in. It was a showdown between a daring bank robber, and a patient FBI agent. Joe was no ordinary bank robber. He was bright, articulate, charismatic, and driven by a dark rage that he summoned up at will. In seven episodes, Joe tells all: the what, the how… and the why. Including why he tried to murder his father. Season 3 - The Burden: Avenger Miriam Lewin is one of Argentina’s leading journalists today. At 19 years old, she was kidnapped off the streets of Buenos Aires for her political activism and thrown into a concentration camp. Thousands of her fellow inmates were executed, tossed alive from a cargo plane into the ocean. Miriam, along with a handful of others, will survive the camp. Then as a journalist, she will wage a decades long campaign to bring her tormentors to justice. Avenger is about one woman’s triumphant battle against unbelievable odds to survive torture, claim justice for the crimes done against her and others like her, and change the future of her country. Season 2 - The Burden: Empire on Blood Empire on Blood is set in the Bronx, NY, in the early 90s, when two young drug dealers ruled an intersection known as “The Corner on Blood.” The boss, Calvin Buari, lived large. He and a protege swore they would build an empire on blood. Then the relationship frayed and the protege accused Calvin of a double homicide which he claimed he didn’t do. But did he? Award-winning journalist Steve Fishman spent seven years to answer that question. This is the story of one man’s last chance to overturn his life sentence. He may prevail, but someone’s gotta pay. The Burden: Empire on Blood is the director’s cut of the true crime classic which reached #1 on the charts when it was first released half a dozen years ago. Season 1 - The Burden In the 1990s, Detective Louis N. Scarcella was legendary. In a city overrun by violent crime, he cracked the toughest cases and put away the worst criminals. “The Hulk” was his nickname. Then the story changed. Scarcella ran into a group of convicted murderers who all say they are innocent. They turned themselves into jailhouse-lawyers and in prison founded a lway firm. When they realized Scarcella helped put many of them away, they set their sights on taking him down. And with the help of a NY Times reporter they have a chance. For years, Scarcella insisted he did nothing wrong. But that’s all he’d say. Until we tracked Scarcella to a sauna in a Russian bathhouse, where he started to talk..and talk and talk. “The guilty have gone free,” he whispered. And then agreed to take us into the belly of the beast. Welcome to The Burden.
