Clinical Pearls: How To Work Up Hypoxia Part 1
I was recently drafting some material for a client who I am tutoring regarding hypoxia. She is in a pulmonary rotation and this is a very common reason for consult. I think when you are providing a consult service (which can receive a high volume of patients) keeping things focused on your organ system, standardizing your approach, and developing automation’s are the key to efficiency. The cool thing is that when you systematically work through the causes of hypoxia you can simplify the process of coming to the most accurate diagnosis. Then you can offer the primary team a suggested plan of action and be the hero (or maybe just uphold your reputation as a trusted colleague 😉). This article is designed to help ease the process of working through the etiology and focuses heavily on pathophysiology. If you can appreciate the pathway of oxygen delivery from the atmosphere all the way through to delivery at the tissue level you can better understand the disease states and more easily come to a diagnosis (or three, as is our common reality).
Clinical Pearls: Shock
Diagnosing the type of shock your patient is exhibiting is clutch when it comes to appropriately treating. Yes, Levophed is our quarterback when it comes to pressor selection, for good reason. But you need to have a darn good understanding of what it can and cannot do, when it is not the ideal choice and when there are better or adjunctive measures that must be undertaken quickly to save your patient. It all starts with coming to an accurate diagnosis. Often in real world practice this is hard to do as multiple states can co-exist, iatrogenic factors obfuscate, and no one piece of data is the be all end all. As with most things in medicine, you have to piece together the data to form the picture. This article reviews the pathophysiology, shares a hemodynamic chart, and overviews how to differentiate shock states.
Clinical Pearls: Ventilator Modes 101
There are a number of reasons why ventilators are confusing, and I’ll break down how to simplify these factors in this blog post. But the big takeaway is this: just because a patient seems controlled well on the vent does not mean he is; do not leave the task of interpreting the vent and the patient’s response to the vent to others. It is incumbent on you to educate yourself about what the knobs, numbers, and waveforms mean in order to better treat your patient. Let’s talk vent basics and it starts with understanding the mode.
Tips For Finding A Nurse Practitioner Preceptor
Options with your school start with knowing your rights, what is required of the school, and whom to network within the school. Beyond that there are several resources I suggest you use. There is also a specific approach I suggest you take to improve odds for success. In the end you may find you really have to hunt to find a nurse practitioner preceptor.
Clinical Pearls: Is It Time To Extubate, An Objective Approach
I spent a lot of years working at the bedside in the ICU. I can tell you one thing a nurse won’t tolerate and that’s an agitated and intubated patient. IYKYK. It’s scary, it’s physically taxing for you, and it’s not good for the patient. So naturally I would immediately call the provider with the “can we extubate” query when they woke up fighting. In my mind they were awake, right? Let’s liberate them from the ventilator!
This is only one scenario in which the clarity I gained in NP school blew my mind at how naive I was as a nurse. Maybe naive isn’t the right word, uninformed perhaps? IDK, I think my point is I didn’t realize there was a systematic approach to assessing extubation readiness. I didn’t properly think through all the reasons why a person would need a vent, nor appreciate all the ways in which a person can fail an extubation attempt. One key factor I learned is that objective medical analysis of the diagnosis and current exam is crucial in predicting risk and then weighing the risk/benefit ratio to determine what is safest for the patient. In this post I’ll walk you through the step by step process of performing this assessment to eliminate as much doubt as possible and set your patient up for success. Skip to the end for a bedside checklist.
Clinical Pearls: Calcium Channel Blocker Overdose
Toxic levels of calcium channel blockers typically induce massive cardiogenic and distributive shock and pressors alone often won't save them. High dose insulin therapy enters the chat here. Think 700 units of rapid onset insulin IV per hour 🤯. Yep, it's gonna be an all hands on deck kind of patient my friends. Read this article to learn about the whys, whos, and hows of CCB overdose mgt.
The Worst Parts Of Being An NP
My number one most viewed youtube video is about the downsides to practicing as a nurse practitioner. I guess I shouldn’t be surprised by that. You want to know what the cons are before diving head first into uncharted waters. It’s a great illustration about how life mimics art. My craft is working as a critical care nurse practitioner and informed decision making is a huge piece of making life and death decisions. As long as the patient and family is aware of the risk/benefit and I do my job well in explaining it to them, we can all go forward with realistic expectations. Same should be true about making a big life decision like going back to school. Since very little in life is all good, anticipating the challenges/cons to this career tract is everything. In this blog post I’ll discuss the biggest bummers to daily life as a nurse practitioner. If you are in a season of deciding on nurse practitioner school, this one is for you.
Clinical Pearls: Intubation Starts Here
Beyond practicing the technique of intubating, nurse practitioners should spend time learning to identify the patients at risk of cardiac arrest. If you can put a finger on the major risk, there are definite strategies you can employ to improve odds of success without decline. In this article, I discuss specific approaches to: GIB/vomiting, hypoxia, shock, asthma, and metabolic acidosis.
The Perfect NP Student
If you are a student reading this, you are already in the top 5% my friend. How am I so omniscient you ask? Well, after serving as a preceptor for the last five years or so I’ve seen all sorts of students. We all are unique and bring different skills, backgrounds, and personalities to the learning space. This should be celebrated, the world would be awfully boring if we all were the same. Having said that, there are trends I see amongst nurse practitioner students, and some of them are not so great. I’m going to tell you what IMO I believe makes for a fabulous student in clinical rotations; one we want to hire. Arguably one of the best qualities is beginning with the end in mind. Those who prepare in advance are not amongst the majority, so congratulations for being an elite! Clinicals are your #1 source for job acquisition, so you want to show up with your A game!
Clinical Pearls:What’s up with the lactate?
In 2001 a research article was published expounding early goal directed therapy as a treatment strategy for sepsis. Key points in the article suggest that physical exam findings are subpar for directing resuscitation and that measures such as lactate, SCVO2, base deficit, and pH are more accurate measures of adequate treatment. There were certainly other factors, and the take home message was to find the source and start antibiotics early, but volume resuscitate until tissue hypoxia improves was the practical application of this research. As a result lactic acidosis has become a bad omen to be feared by all. Several guideline updates have since been published, the most recent in 2021 with weak evidence to suggest using lactate as an end-point measurement. Practically speaking though, the word is out that a high lactate = bad bad badness. I’m not saying it isn’t bad, but there are plenty of reasons why an elevated lactate alone is not the end of the world. In this post we’ll discuss causes for lactate elevation, what should be cause for alarm and what shouldn’t, and how to manage it.
Mentors: Game Changers?
What is the most insightful thing someone ever told you? When I try to narrow down my answer to this I struggle. I lost my mom when I was twenty four years old. It was traumatizing and also character building. She was my mentor in all ways and without her presence I have struggled in my life, particularly with making hard decisions. Thankfully I have had some career-guiding, life-changing people come into my life at exactly the right moments. The story I share most often is in regards to deciding to go back for a masters degree. A friend of my moms (who happened to be a nurse at the hospital where I worked) said “Briana, what’s your hangup?” I told her the big issue was the burden I would put my husband and children through for two straight years. Especially the girls who wouldn’t see as much of me. Her response “Honey, two years will pass whether you are in school or not, where do you want to be in two years? And what will teach your girls more, being present for all the events or role modeling how hard things are done?”
Okay universe, I hear ya.
In this post I will discuss the difference between a mentor and a coach, what they can offer you, how to find one, and how to make the most of your time.
Clinical Pearls: VBG vs ABG
There is a legitimate reason why ER providers consistently order a VBG over an ABG and the ICU provider then may or may not believe the VBG choosing to tack on an ABG instead.
Many patients in the hospital require assessment of their acid base balance and oxygenation/ventilation status which is best quantified from serum arterial samples. Additionally, the ABG provides expedited lab results such as hemoglobin, potassium and other electrolytes, and lactic acid. These values are very helpful in making a rapid diagnosis and treatment plan. A venous blood gas seems to be the standard replacement for an arterial blood gas in the emergency department. It does offer some benefits, but has limitations as well which should be acknowledged.
The focus of this article is to describe the pros/cons of using a VBG as a surrogate, the exclusion criteria, and the method of converting a VBG to an ABG.
Clinical Pearls: DIC
One of the rare and weird things in medicine that combine a dramatic constellation of opposites. Caring for someone in the throes of badness from two dichotomous problems leaves one in a state of floundering. Do I treat the clotting or do I treat the bleeding? What will kill them first? It’s universally known that getting the diagnosis of disseminated intravascular coagulation is a dreaded event. DIC is a downstream complication that arises late in the game with several diagnoses that we see in the ICU, and unfortunately in our maternal population. Every time an OB calls our team to see or transfer a patient to ICU my shoulders instantly feel tense. Let’s talk about the pathophysiology behind this dreaded state and what our treatment options really are.
Nurse Practitioner Boards Preparation
After one has achieved the degree, put in the herculean effort to study, stressed beyond reason, hyper-fixated on all the possible outcomes, and then stood in this place of last minute test anxiety, bargaining with one’s maker is where you may find yourself. Based on the conversations I have with NP students I precept and online / via my mentoring business, I can confidently say only a tiny fraction of new grads are immune to this fear. There are some things out of our control as a neophyte, but boards preparation is not one of them. Taking control of how you ready yourself for this exam definitely impacts anxiety level as well as success rate. In this post I will discuss the best way to prepare for your nurse practitioner board certification exam
Clinical Pearls: Liver Failure
Oh the ways the liver can fail. As a new nurse practitioner this one was hard to get down. Cardiology is generally seen as the bee all end all when it comes to keeping our bodies running, but I’d like to talk about the under appreciated liver. Hepatology is fascinating because the normal function of the liver is supremely multi-faceted. Throw in a little pathology and any number of pathways can be deranged and within those any degree of severity can be seen. From acute to chronic to acute-on-chronic, severity can run the gamut. Decompensated cirrhosis is a common killer in most ICU’s. Given how poorly understood this disease state is, I’d like to talk about the complexity, progression, prognosis, and management of liver failure in the intensive care unit.
Clinical Pearls: Evaluating For Intubation
When is it time to say it’s time? I think back on the really bad days of the pandemic when I walked from room to room asking myself this question repeatedly. Honestly, for intensive care unit level covid that’s what it felt like - a few random meds that typically didn’t help, supportive care, and careful vigilance for when it was time to go on the dreaded vent. Our patients feared it, our families feared it; it was the elephant in the room every time you walked in. Outside of covid pneumonia, there are a million reasons why a patient needs mechanical vent support and failing lungs are just one component. This is a very common question I get asked when I am training a nurse practitioner student Here’s how I approach evaluating a patient for intubation need.
NP vs RN: Differences in employment structure
This topic comes from a question I received from a client asking to explain how nurse practitioners fit into a physician run group. She expressed her surprise to learn that many APPs and physicians who work in a hospital are not employed by the hospital and asked for feedback about how this works and how nurse practitioners fit into this model. I definitely understand this confusion. As nurses, we are used to standard hospital or health system employment with clear hierarchical management. In this post I’ll talk about my experience with this and the main differences between NPs and RNs in regards to:
Who employs you.
Who manages/directs you.
How you get paid.
Who your colleagues are.
Clinical Pearl: Status Asthmaticus
Not a common problem in most ICU’s, but you do get the occasional severe case of asthma. When you do, it can get a little hairy. Mostly because these are generally young people and there’s only so much you can do. Sort of like Covid when it gets bad, there’s not much to offer. You provide the medicine, the supportive devices and wait for their bodies to heal themselves. Same with asthma, you order the standard treatment and then pray it doesn’t get to a point where you have to intubate. In large part, our primary goal in ICU asthma is to not make them worse with counter-intuitive ventilator strategies. Let’s talk asthma.
Toxic Workplaces And What to Do About Them
I talk to a fair amount of nurse practitioners who are in a space of indecision. My goal is to help them sort out what will best serve their {whole} life goals. It’s always about balancing work-life factors with career goals. Some of them are considering leaving the profession and going back to the bedside or doing something else altogether. Some are coming to me seeking interview/job acquisition help and what we discover is that their confidence has been wrecked by a unhealthy work environment. I’d be willing to bet many of you have experienced this in the past or are stuck in this situation currently. It’s truly a sad state of affairs these days particularly for nurse practitioners. In this article I wanted to talk about this phenomenon and what some options may be for you.
Clinical Pearls: Pressor Selection
The foundation of critical care practice stands upon heart and lung support. As you know a multitude of problems lead to these downstream complications, but at its core what we do in the unit is handle worst case scenarios. Even for a new nurse practitioner with loads of years at the ICU bedside, pressor selection can be difficult at first. What I hear from students is “Levo, let’s just start Levo.” They say this because it has been their experience and it’s of course discussed everywhere. But when I ask them to defend the selection there can be a dearth of knowledge. Ultimately, they may be right, but I argue that as a competent provider one must have a good understanding of the pharmacodynamics of the drug AND the pathophysiology of the disorder you are treating. Why? Because while the physician/team you are practicing with currently may never question you, at some point you will need to explain your rationale. And on a baser level you need to accurately treat the problem or you could 1)chose something ineffective 2)make things worse or 3)harm the patient. Let’s talk vasopressors.
