Evidence for Physical Fitness to Slow Loss of Cognitive Function via Lowered Blood Pressure
As is true of excess weight, the raised blood pressure appears to have a lower threshold for causing long-term harm to health than is commonly thought. Negative effects increase as blood pressure increases, but the point at which harms start is surprisingly close to normal blood pressure ranges. More aggressive control of blood pressure via antihypertensive drugs and lifestyle changes produces benefits even when pushing it back down into what the normal range. The boundary at which raised systolic blood pressure is considered to be a problem, veering into the territory of hypertension, was recently lowered by ten points.

Device Measures Hemoglobin More Accurately in Dark Skin
Researchers at the University of Texas at Arlington, in collaboration with Shani Biotechnologies, a local firm, have created a point-of-care device that can accurately measure hemoglobin levels and perform pulse oximetry in individuals with dark skin. At present, methods to determine hemoglobin levels at the point of care, such as pulse oximetry, are inaccurate in individuals with higher levels of melanin in their skin, and there is a clear need to develop alternatives that work for everyone. Instead of the red-infrared light used by common pulse oximeters, this new device relies on a blue-green light in addition to assess...

How to Take Charge of Your ADHD Voicemail Hell
Ever find yourself missing important messages because your voicemail box is filled with half a decade of unlistened to calls? There might be a solution for that.Adult ADHD is almost like the Baskin Robbins of the mental health community. There are so many flavors of ADHD, you can be forgiven for questioning if they’re all from the same diagnosis. Some adults with ADHD daydream. Others are chronically late. Some run their mouths off with their feet in the way. Others never stop talking. Some forget why they went to the store. Others forget who they just called because something distracted them after they dialed. There...

What Is GHB Anyway?
Let’s face it, there are a whole bunch of street drugs out there that we as EMS caregivers should understand. While we can’t always be expected to identify the exact drug a patient has ingested. We do need to be able to predict a given drugs effect on the body.
We should also be able to take a fair guess at the identity of an ingested drug based on our evaluation of the patient’s physical presentation. GHB is one of those drugs that can be hard to nail down based on the physical signs. But it does leave some clues – if you know what your look for.

GHB is short for ...

To Walk or Not To Walk?
The Happy Medic (THM) recently posted a fantastic topic on his blog. I love diving into controversial decisions that we have to make every shift. Here’s one of those questions that we need to answer on just about every call. Should we walk the patient to the pram or carry them?
This is one of those things that we have no choice but to address in every system on just about every call. How to we get the patient to the pram? When is it OK to walk them?
It seems like this subject got rolling on Justin’s (THM) blog when EMS types from around the country started sending him feedback about his role in the documenta...

What Is Muscular Dystrophy Anyway?
Since we’ve been talking about the fill the boot campaign the annual MDA telethon, why not use our “what is” series to take a closer look at the group of diseases we commonly refer to as muscular dystrophy.
While most EMS caregivers have a general idea of what to expect in a muscular dystrophy presentation, few of us are as knowledgeable as we should be about what muscular dystrophy is and what it does to the body. Let’s take a closer look.
While we tead to refer to muscular dystrophy as a single defined disease process, it is actually a group of disease that share some common characteristics. Add to that the...

Assessment and Scope of Practice
It’s never comfortable to be placed under a microscope. Especially when the dude looking through the microscope is The Rogue Medic, Tim Noonan. Tim’s a great dude, but he’s not the guy you want picking through your knowledge sock drawer. He’s thorough, he’s smart and he’s willing to analyze the details long after you and I have gone to bed.
If you don’t already read Tim’s blog you should. He’s a fantastic EMS blogger. That being said, I wasn’t terribly excited when he posted a comment on my post “I’m Only An EMT Basic” announcing that his comments on the piece could be found over...

Awake ECMO
Extracorporeal membrane oxygenation (ECMO) is used for treatment of severe respiratory or cardiopulmonary failure. Usually these patients are sedated and mechanically ventilated, though at lower tidal volumes to reduce lung injury and permit lung recovery.
The concept of Awake ECMO is to do away with mechanical ventilation permitting the patient to eat, drink, sit up and even possibly walk. They can also participate in physiotherapy. One situation in which it is considered is in those who are in bridge to transplantation situation. One study documented 6 month survival after lung transplantation as 80% in the awake ECMO g...

What is the cause of central cyanosis in Osler-Weber-Rendu syndrome?
Central cyanosis in Osler-Weber-Rendu syndrome is due to pulmonary arteriovenous fistula. Those with Osler-Weber-Rendu syndrome or hereditary hemorrhagic telangiectasia have multiple capillary hemangiomas on skin, lips, mucosa of nose, upper and lower respiratory tract and gastrointestinal tract. Central cyanosis can occur when there are multiple pulmonary arteriovenous fistulae with significant right to left shunt allowing desaturated blood to reach the systemic circulation.

Depression: The Highway to Success Has an Awful Lot of Detours
I’ll write a bit vaguely today because I want to touch upon some things that are family matters and how they impact me.Recently, I have noticed longtime readers of my blog have leapfrogged over me while my life has become stagnant. I caught myself beginning to feel bitter about it, so instead of letting that bitterness settle into depression, I will share some things that I have learned instead.My life took a detour a few years back, if eleven can be called of few. It was as if I was forced to take an exit and found myself on the service road bumping along besides the highway, falling behind all the other traffic. I ...

90 year old with acute chest and epigastric pain, and diffuse ST depression with reciprocal STE in aVR: activate the cath lab?
ConclusionsSTE-aVR with multilead ST depression was associated with acutely thrombotic coronary occlusion in only 10% of patients. Routine STEMI activation in STE-aVR for emergent revascularization is not warranted, although urgent, rather than emergent, catheterization appears to be important.===================================MY Comment, by KEN GRAUER, MD (11/5/2022):===================================Our thanks to Drs. El-Baba and McLaren — for their presentation in today’s post about an important topic worthy of our periodic reminders. We’ve presented many variations on this theme on...

What is the commonest site of RVOT obstruction in TOF?
What is the commonest site of right ventricular outflow tract obstruction in tetralogy of Fallot? The commonest site of right ventricular outflow obstruction in Tetralogy of Fallot is infundibular (subvalvar) pulmonary stenosis. Obstruction can be at other locations like valvar pulmonary stenosis, supravalvar pulmonary stenosis and annular pulmonary stenosis. There could be a combination of these lesions as well. Infundibular spasm with dynamic worsening of right ventricular outflow obstruction is thought to be one of the pathophysiological mechanisms of cyanotic spells in Tetralogy of Fallot. Immature respirat...

Neck Sensor Helps Masked Clinicians Communicate
Researchers at Pohang University of Science & Technology in South Korea developed an auditory sensor that lets people wearing face masks, such as clinicians, to communicate more easily. The device is essentially a wearable microphone that picks up the vibrations of the skin in the neck that occur when someone talks. The researchers hope that it could be useful for clinicians who must wear face masks as protection against pathogens such as COVID-19, but who also need to communicate with each other clearly. Other applications of the new device include respiratory monitoring, where the sensor could record the frequency an...
