High Blood Pressure Diet Nutrition HealthiNation
HOST Hello and welcome to HealthiNation. I'm Sharon Richter. As a registered dietitian, many of my clients have high blood pressure or hypertension. Through diet, we can control hypertension. The DASH diet is an excellent approach to do this. I'm going to walk you through exactly what the DASH diet consists of so you can control your blood pressure. The DASH in the DASH Diet stands for Dietary Approaches to Stop Hypertension. It was developed by the National Heart, Lung and Blood Institute and has been proven to lower cholesterol, lower blood pressure and also help with insulin sensitivity. The main part of the DASH diet.
Is watching portion sizes. So lets go through some food groups to help figure out what a serving size is. Let's begin with some grains. One slice of bread is a portion. Or, you can have half a cup of rice, half a cup of pasta and that's going to be a serving of grains. Next we can think about two important nutrients, magnesium and potassium. They're going to be found in fruits and vegetables. 1 serving of a vegetable is a cup spinach one serving size of a fruit would be a medium.
Apple, orange or pear. Now, lets take a look at dairy products. What you want to be concerned about is the fat content. A whole glass of milk is going to have 8 grams of fat., 2 percent milk will have 5 grams of fat, and skim milk has less than 1 gram of fat. Each serving of dairy is about a cup a cup of yogurt, a cup of cottage cheese or a cup of milk. Chocolate milk counts too. Now, lets take a look at some protein choices. They include, fish, chicken, eggs and meat.
What you want to be careful of about is the amount of salt added to them. I'll give you an example, when you go to the deli, try to get fresh turkey as opposed to the processed, which has a lot more salt added to it. Now in terms of portion sizes, I do a trick with my hand. The palm of your hand is good for red meat, up to the first digit for chicken and your entire hand for fish. Now Now in terms of eggs, one whole egg is going to be equivalent to a serving size of protein,.
Or for the low fatlow cholesterol version, use two egg whites. That's going to be equivalent to one serving of protein. Now why don't we start talking about some fats. Fat is actually necessary in your diet it helps control your body's temperature, protects your organs and is excellent for your hair and your skin. Lets look at some different sources. Good sources are going to be nuts, seeds, peanut butter, olive oil, and avocados. They're all unsaturated types of fat. The ones you want to stay away from are saturated sources.
Such as, butter and margarine. A serving size would be about 2 tablespoons of peanut butter or 20 almonds. Again, when you're choosing the good sources such as peanut butter or nuts, try the unsalted version. Salt is going to be related to your blood pressure. This is just an introduction to the DASH Diet. You should consult with your physician or dietician to find out exactly what's going to be right for you. Keep in mind portion sizes and try to avoid added salt when possible. Thank you for being a part of HealthiNation.
Myofascial Pain Syndrome and Trigger Points Treatments, Animation.
Myofascial pain syndrome is a common chronic pain disorder that can affect various parts of the body. Myofascial pain syndrome is characterized by presence of hyperirritable spots located in skeletal muscle called trigger points. A trigger point can be felt as a band or a nodule of muscle with harder than normal consistency. Palpation of trigger points may elicit pain in a different area of the body. This is called referred pain. Referred pain makes diagnosis difficult as the pain mimics symptoms of more wellknown common conditions. For example, trigger point related pain in the head and neck region may manifest as tension headache,.
Temporomandibular joint pain, eye pain, or tinnitus. Symptoms of myofascial pain syndrome include regional, persistent pain, commonly associated with limited range of motion of the affected muscle. The pain is most frequently found in the head, neck, shoulders, extremities, and lower back. Trigger points are developed as a result of muscle injury. This can be acute trauma caused by sport injury, accident, or chronic muscle overuse brought by repetitive occupational activities, emotional stress or poor posture. A trigger point is composed of many contraction knots where individual muscle fibers contract and cannot relax. These fibers make the muscle.
Shorter and constitute a taut band a group of tense muscle fibers extending from the trigger point to muscle attachment. The sustained contraction of muscle sarcomeres compresses local blood supply, resulting in energy shortage of the area. This metabolic crisis activates pain receptors, generating a regional pain pattern that follows a specific nerve passage. The pain patterns are therefore consistent and are well documented for various muscles. Treatment of myofascial pain syndrome aims to release trigger points and return the affected muscle to original length and strength. Common treatment options include.
Manual therapy, such as massage, involves application of certain amount of pressure to release trigger points. The outcome of manual therapy strongly depends on the skill level of the therapist. The Spray and Stretch technique makes use of a vapor coolant to quickly decrease skin temperature while passively stretching the target muscle. A sudden drop in skin temperature provides a pain relief effect, allowing the muscle to fully stretch, and thus releasing the trigger points. Trigger point injections with saline, local anesthetics or steroids are well accepted as effective treatments for myofascial trigger points.
Interpreting Arterial Pressure Waveforms, by Jim DiNardo, MD, FAAP for OPENPediatrics
Interpreting Arterial Pressure Waveforms, by Dr. James DiNardo. Hi. My name is Jim DiNardo. I'm a professor of anesthesia at Harvard Medical School, and one of the cardiac ICU attendings here at Children's Hospital Boston. And I'm going to talk a little bit now about what information we can gather from looking at an arterial line trace. Arterial System. To start with, it's important to remember that the shape of the arterial trace seen on a monitor is really due to the interaction of essentially two variables, which is the patient's stroke volume that is the volume of blood that's ejected into the arterial.
System with each beat and the compliance of the arterial system into which the blood is being ejected. So when we're looking at A line traces, it's important to remember that although the pulse pressure can be an index of stroke volume, it depends entirely on the compliance of the patient's arterial system. And the reason this is important is that, let's assume for a moment that we have two patients, one who is young and has a very compliant arterial system, and one who is older or, in fact, very elderly and has a very noncompliant arterial system. And let's.
Assume that those patients have the same stroke volume. The patient with the compliant arterial system is going to have a much narrower pulse pressure that is the difference between the systolic and the diastolic pressure than the elderly patient with the noncompliant aorta, who's going to have a very wide pulse pressure because the same stroke volume is injected, essentially, in the circumstance of the older patient, something resembling more of a lead pipe, where the entire stroke volume will be displayed as a pressure and then a deterioration of that pressure.
And in the example of a younger person with a very compliant arterial system, the stroke volume in essence will almost be completely damped out by an infinitely compliant system. Therefore the volume ejected will appear more like a straight line in an infinitely compliant arterial system. And it will appear as a square wave in a noncompliant system. Dicrotic Notch. Now, the other thing that people talk about a lot when they look at A line traces is the dicrotic notch, which is a notch on the descending limb of the A line trace. And oftentimes,.
How the ear works
Many of us take for granted a very extraordinary organ. our ears to understand the ear, we need to understand what sound is. the speakers you are listening to right now are vibrating.flexing in and out causing a wave of pressure through the air The frequency of these waves, or the speed at which the sound creating surface moves back and forth affects the pitch of the sound The level of air pressure in each wave is directly related to how loud the sound is. the outer part of our ear catches these waves. It faces forward and has a specially designed.
Structure of curves helping us to determine the direction of sound, and emphasize frequencies used in human speech Now that the sound waves are caught, they travel through the ear canal and strike against our eardrum. a thin membrane about 10 mm wide. now that we received the sound, the middle ear transfers this energy. The smallest bones in your body, the malleus, incus, and stapes start in motion. the malleus is attached to the eardrum, and as the sound travels along the force is amplified by leverage until it arrives at the stapes which acts like a reverse piston creating.
Waves in the fluid of the inner ear The most significant increase in pressure is caused by pneumatic amplification. the face of the stapes has a surface area of 3.2 square mm, while the eardrum has a surface area of 55 square mm. Using this, along with leverage through the malleus and incus, the final pressure is 22 times greater than when the sound first arrived. Now we come to the most complicated part of hearing. the coke le ah. In reality, it is coiled up, but it is easyer to understand straightned out.
There are actually three chambers inside, but lets take a look at the central part. The stapes is cuasing pressure waves to travel through the structure. Along the inside wall is about 2030k reed like fibers. as the waves move along they encounter fibers with the correct resonant frequency and energy is released. These fibers aren't actually what give us the signal that we heard something. There is a special structure next to these fibers containing hair cells. When the hair fibers resonate, they cause the hair cells to move, which then sends an electrical impulse to the cochlear nerve,.
And on to the brain. Certain pitches of sound will resonate in specific locations, and louder sounds will cause more hair cells to move. Our brain interprets all this raw data, making it possible to enjoy things like music, or an engaging conversation. Just to think that all of this is happening in your head right now at full speed. And not just one, but two of these sophisticated instruments are giving you the amazing sense of hearing. This is just one of the amazing systems found in the human body that go far beyond our humble human understanding.
Osmosis and Tonicity
Before we take a look at how osmosis and tonicity affect a cell, let's review what each of these terms means. Osmosis represents the diffusion of water across a semipermeable membrane. The term tonicity refers to the relative solute concentration of two environments separated by a semipermeable membrane. In other words, by comparing the tonicity of the solution, you can determine the direction in which osmosis will occur. To demonstrate how tonicity affects a cell, let's place some red blood cells into a beaker containing pure water. In this case, the solute concentration is greater inside.
The cells, than in the surrounding water. In other words, the contents of the cells are hypertonic in relation to the hypotonic contents of the beaker. Because of this, osmotic pressure results in the diffusion of water across the membrane and into the cells. Over time, if enough water enters the cells, the cell membranes may burst. This is called lysis. Now lets place the red blood cells in a beaker containing a solution of salt, such as sodium chloride. Since the contents of the beaker beaker are hypertonic in relation to the interior of the cell,.
The water within the cell will diffuse across the membrane and into the contents of the beaker. This causes crenation or shrinking of the cells. If the red blood cells are placed in a beaker whose contents match the tonicity within the cells, then there is no net gain or loss of water. The environments within the beaker and inside the cells are said to be isotonic, or the same. An important thing to remember, is that osmotic pressure always causes water to move from a hypotonic environment toward a hypertonic environment. In other words, water moves toward.
Why Shouldnt You Take Medicine with Grapefruit Juice
If you're like me you probably tune out pharmaceutical commercials when they air on TV. But there's one drug warning that stands out Don't take this medication with grapefruit juice. But what's wrong with grapefruit juice And what's in grapefruit juice that isn't in other citrus juices, like orange juice, the normal one Grapefruit is full of a type of organic compound called furanocoumarin, which interferes with the activity of an enzyme in your small intestine called CYP3A4. Problem is, that interference means your body will absorb more of certain medicines, for.
Things like high cholesterol, high blood pressure, and anxiety, than it's supposed to. This enzyme's normal job is to chemically change certain potentially dangerous compounds before they can get to your bloodstream or liver. That way, they're easier for your body to eliminate. But it also recognizes lots of different medications, and deactivates them the way it would any chemical meaning that a large amount of the drug you take never actually makes it into your body to do its job. Except that the compounds in grapefruit deactivate the enzyme. Just one glass of grapefruit juice.
Is enough to knock out nearly half of it. So, if the enzyme deactivates drugs, and the compounds in grapefruit deactivate the enzyme, that sounds like a good thing. More effective medications! No! It is not a good thing, because one of the first things researchers do in a clinical trial is work out a safe dose, one that takes into account your body's attempts to remove toxins, including that enzyme. When your grapefruit juice gets rid of the enzyme, you're suddenly getting way more of the drug than that safe dose.
That could cause serious problems for your liver, which normally filters out these medications after they've done their job. You can also have too much of the medication in you! If you drink a bunch of grapefruit juice while you're taking blood pressure medication, for example, your blood pressure could fall too far. So if you take any meds but you're a big fan of grapefruit juice, you might want to talk to your doctor before you crack open a new bottle. Or just switch to orange juice, which tastes much better anyway.
