Fluids in our Body - Water, plasma, blood plasma, When fluids or electrolytes become imbalanced, electrolytes, proteins, cells, other soluble particles individuals are at risk for organ system dysfunction. (solute) EXAMPLES OF BODY FLUIDS Amniotic fluid, Peritoneal fluid, Aqueous humor Pleural fluid, Bile Pus, Blood plasma Saliva, Breast milk Sebum, Cerebrospinal Serous fluid, fluid, Semen, Cerumen Sputum, Chyle, Synovial fluid, Exudates, Sweat, Gastric juice, Tears, Lymph, Urine, Mucus, Vomitus Pericardial fluid, As we age the percentage of our body fluid is decreasing FUNCTIONS OF WATER IN THE BODY 1. Transporting nutrients to cells and wastes from cells 2. Transporting hormones, enzymes, blood platelets, and red and white blood cells o Blood is the primary transport of fluid, made up of water 3. Facilitating cellular metabolism and proper cellular chemical functioning o Dissolved proteins lipoprotein, dissolve to be transported on cells for organs to function, so we need homeostasis on fluid Intracellular fluids (ICF) 4. Acting as a solvent for electrolytes and o are found inside cells and are made up of nonelectrolytes protein, water, electrolytes, and solutes. 5. Helping maintains normal body temperature o Most abundant electrolytes found in icf: 6. Facilitating digestion and promoting elimination potassium 7. Acting as a tissue lubricant o Body composed of 60% of icf o Amniotic Fluid – acts as cushion o 40% of your weight is icf Extracellular fluids (ECF) BASIC FLUID AND ELECTROLYTE o are fluids found outside of cells. CONCEPTS o Most abundant in ECF: Sodium – our body The body is in a constant state of change as fluids regulate sodium level to control the and electrolytes are shifted in and out of cells within movement of water into and out of ECF due the body in an attempt to maintain a nearly perfect to osmosis balance. o Salt attracts water A slight change in either direction can have significant consequences on various body systems EXTRACELLULAR BODY FLUID Understand physiologic changes in body if you have TYPES OF EXTRACELLULAR FLUID prob in fluid and electrolyte The first type is known as Urine output per hour- 30-40 ml intravascular fluid that is o 1500 ml ang naiihi sa isang araw or 1.5 urine found in the vascular excrete system that consists of o Kidney and liver filtrate our waste arteries, veins, and HOW TO DIAGNOSE capillary networks.

Factors may lead to deficient fluid volume: diarrhea Pitting edema – to grade (bata prone sa dehydration) , vomiting, inadequate edema oral fluid intake, excessive diuretic use, insufficient The remaining extracellular fluid replacement. fluid, also called Adequate in intravascular fluid is decrease of blood transcellular fluid, refers to pressure due to additional work load of your heart TRANSCELLULAR fluid in areas such as that will supply to your body FLUID cerebrospinal, synovial, Severe loss can lead to hypovolemic shock and intrapleural, and cellular death because organs are not able to receive gastrointestinal system oxygen rich blood supply If you have hypovolemia: o low extracellular volume because there is FLUID MOVEMENT loss of water and sodium in your body. Fluid movement occurs inside the body due to osmotic pressure, hydrostatic pressure, and osmosis PROPER FLUID MOVEMENT DEPENDS ON: 1. Intact and properly functioning vascular tissue lining o If you have intact vascular tissue lining, it prevent fluid from leaking out of your blood vessels 2. Normal levels of protein content within the blood o Protein in our blood is in form of albumin. 3. Adequate hydrostatic pressures inside the blood vessels o Before hydrostatic pressure there should be osmotic pressure- pressure that holds the water inside you blood vascular compartment. o Hydrostatic pressure- Pressure exerted by your blood against the capillaries CAUSES OF HYPOVOLEMIA HYDROSTATIC PRESSURE Weakness Pressure that a contained fluid exerts on what is Fatigue confining it. Dizziness Orthostatic hypotension Hypovolemic shock- severe intravascular fuid loss Increase thirst Dehydration- pag sobrang init nag eevaporate. You were not able to replace fluid loss Trauma- severe bleeding from trauma. Ex: blood loss due to vehicular accident Execessive fluid accumulation between your cells- example sepsis, due to spsis nagkakaron ng inflammation Renal disease- body were not able to properly filtrate toxins in your body FILTRATION Congestive heart failure- additional workload on Occurs when hydrostatic pressure pushes fluids heart, mapapagod and solutes through a permeable membrane so Signs and symptoom they can be excreted.

Example: Sodium Potassium Pump – use energy to Waste products are excreted in the form of urine maintain higher of K in the intracellular and sodium Excess fluid and waste product to be excreted from Sodium Potassium Pump – Regulate sodium and your body in the form of urine potassium level in IC and EC compartment Sa nag dadialysis- yung dializer and nagsisilbing kidney nila OSMOSIS Water movement through a semipermeable membrane, from an area of lesser solute concentration to an area of greater solute concentration, in an attempt to equalize the solute concentrations on either side of the membrane. Osmosis causes fluid movement between the intravascular, interstitial, and intracellular fluid compartments based on solute concentration. Movement of fluid If there are more particles in volume. It is considered as concentrated FLUID AND ELECTROLYTE If you eat amount of large salty foods, soium level will REGULATION increase. So magiging concentrated The body must carefully regulate intravascular fluid Due to elevated solute concetration in your blood accumulation and excretion to prevent fluid volume stream- osmosis cause fluid to be pulled form your excesses or deficits and maintain adequate blood interstial and intrancellular to balance.

As you recall, elevated sodium levels in the blood cause the osmotic movement of water out of the cells to dilute the blood. As fluid cell shrinks we HYPERNATREMIA can see symptoms like: Vasopressin (also called lethargy, confusion, antidiuretic hormone) is a irritability because it has substance naturally produced something to do with in the body that helps nerve function regulate the amount of There are some water in the body by treatment: decrease controlling how much water is sodium intake, increase excreted by the kidneys. oral water intake, Pituitary gland produces and rehydrate with releases especially when you hypotonic IV solution so bp or blood volume goes that you can maintain down or if your electrolytes fluid balance in and out ROLE OF become too high particularly of your cell VASOPRESSIN sodium concentrated Vasopressin decreases water excretion by the kidneys, which retains more water in the body and dilutes the sodium. if you have too much sodium your pituitary gland will signal your kidney to stop excreting water because your body A decreased sodium needs water to dilute your HYPONATREMIA excess sodium level in the blood The syndrome of inappropriate secretion of antidiuretic hormone PATHOPHYSIOLOGY: regulation of potassium by develops when too much aldosterone in your kidneys and your aldosterone antidiuretic hormone cause reabsorption of sodium and excretion of (vasopressin) is released potassium. For example, in response in your by the pituitary gland under potassium level rising or falling your adrenal cortex certain inappropriate will release aldosterone and it will target your kidney conditions, causing the body in response your kidneys will excrete potassium and to retain fluid and lower the will reabsorb sodium so it can normalize blood blood sodium level by sodium potassium levels SYNDROME OF dilution. INAPPROPRIAT if you have too much sodium E SECRETION your pituitary gland will OF signal your kidney to stop ANTIDIURETIC excreting water because your body needs water to HORMONE dilute your excess sodium (SIADH) Antidiuretic hormone (ADH) mainly affects our kidneys’ ability to reabsorb water. Under normal circumstances, our body signals ADH release for a variety of reasons. Example: if you are dehydrated your body will signal release of antidiuretic hormone so that your kidney release less water through your urine in order to save more water in your body, if you treat dehydration by drinking water, your body will stop signaling the release of HYPERKALEMIA your antidiuretic hormones There is an increased potassium levels in the and your body will release blood. more water through your Hyperkalemia can be caused by kidney failure, urine. metabolic acidosis, and administration of In most people with SIADH, potassium-sparing diuretics or oral/intravenous drinking water doesn’t potassium supplements. adequately suppress ADH Signs and symptoms of hyperkalemia are release, and their urine generally cardiac in nature and include irritability, remains concentrated. cramping, diarrhea, and electrocardiogram (ECG) This leads to water retention, abnormalities. - Kasi potassium has something to which dilutes our blood. This do with our muscle contractions, and our heart is then leads to low levels of a muscle. sodium in our blood As hyperkalemia worsens, ECG abnormalities (hyponatremia). may progress to cardiac dysrhythmias and Hyponatremia- there is an cardiac arrest. - you should never administer IV Inappropriate secretion of potassium through IV push as it will cause cardiac antidiuretic hormone dysrhythmias and cardiac arrest. POTASSIUM Caused by administration of potassium-sparing Potassium levels normally range from 3.5 to 5.1 diuretics or oral/intravenous potassium mEq/L. supplements.- because potassium sparing Potassium is the most abundant electrolyte in diuretics is a type of diuretic that helps eliminates intracellular fluid and is maintained inside the cell by excess sodium and water from your body but the the sodium potassium pump. problem is it retains potassium in your body that's Potassium is necessary for normal cardiac function, why taking it can cause hyperkalemia.

Acute hypophosphatemia can be caused by acute Vegetable citrus, chocolate (dark chocolate) alcohol abuse, burns, diuretic use, respiratory alkalosis, resolving diabetic ketoacidosis, and starvation. Chronic hypophosphatemia is caused by hyperparathyroidism, vitamin D deficiency, prolonged use of phosphate binders, and hypomagnesemia or hypokalemia. Hypophosphatemia is usually asymptomatic, but in severe cases, it can cause muscle weakness, anorexia, encephalopathy, seizures, and death- phosphorus has something to do with nerve function, membrane building and retain, energy metabolism Treatment for hypophosphatemia includes treating what is causing the imbalance, oral or IV phosphorus replacement, and increased phosphate-containing foods in the diet. Eat fruits, vegetables, cereals, meat and diary product. MAGNESIUM Magnesium levels typically range from 1.5-2.4 mEq/L Magnesium is essential for normal cardiac, nerve, muscle, and immune system functioning. Dietary sources of magnesium include green leafy vegetables, citrus, peanut butter, almonds, legumes, and chocolate CHLORIDE The normal range for chloride in adults is roughly Test to know how well our lung are able to move between 98 and 107 milliequivalents of chloride oxygen into the blood and remove our CO2 from our per liter of blood (mEq/L) blood Maintains proper ph level, stimulates stomach acid From collecting blood on your radial artery rather that needed for digestion, stimulate muscle function than brain , facilitate flow of oxygen 10 cc syringe pero 10 ml ang kukunin pero sa ospital Chloride carries an electric charge and therefore is 3cc syringe lang ang ginagamit.

Any excess pressure of arterial carbon dioxide (PaCO2), the amount is excreted in urine. bicarbonate level (HCO3), and the oxygen saturation Chloride is usually bound to sodium, and therefore level (SaO2) the amount in blood tends to coincide with sodium Prior to collecting blood gases, it is important to levels. ensure the patient has appropriate arterial blood flow Chloride is involved in many of our bodily functions. to the hand. Similar to sodium and potassium, chloride creates This is done by performing the Allen test. specific channels in the membranes of our cells When performing the Allen test, pressure is held on which help to carry different vital tasks. both the radial and ulnar artery below the wrist. This mineral is needed to help red blood cells Pressure is released from the ulnar artery to check if exchange oxygen and carbon dioxide in both the blood flow is adequate. If arterial blood flow is lungs (taking up oxygen and releasing carbon adequate, warmth and color should return to the dioxide) and other parts of the body (delivering hand. oxygen and taking up carbon dioxide). Interpreting Arterial Blood Gases: Chloride also plays a role in the digestion of foods, by supporting the production and release of hydrochloric acid (HCl) in the stomach. Key in controlling water and the type of cell that goes in and out. It has something to with balance of the body including maintaining a proper pH level. Help us carry messages in our nerves, digestion, release of hydrochloric acid for proper digestion and absorption food. HYPERCHLOREMIA Excess chloride levels in the blood. It can be caused by severe dehydration, diarrhea, or metabolic problems in which the blood becomes too acidic, such as with kidney disease. A high salt diet can lead to an excessive intake of sodium chloride, which is associated with elevated blood pressure - if you have high bp you need to MODIFIED ALLEN’S TEST maintain a low salt low fat diet The symptoms that may indicate hyperchloremia Put pressure on both the radial and ulnar artery are usually those linked to the underlying cause of below your wrist. Pressure being release to check if the high chloride level. Often this is acidosis, in blood flow is adequate. If it arterial pressure is which the blood is overly acidic. These symptoms adequate, warms and color should adequate may include: When performing the Allen test, pressure is held on o fatigue both the radial and ulnar artery below the wrist. o muscle weakness Pressure is released from the ulnar artery to check if o excessive thirst blood flow is adequate. If arterial blood flow is o dry mucous membranes adequate, warmth and color should return to the o high blood pressure hand. HYPOCHLOREMIA pH Low level of chloride in the blood A loss of chloride in the body usually accompanies conditions that cause sodium losses. Diuretic medications that remove fluid through the kidneys can also cause decreased chloride levels. In cases of sudden, very high levels of blood glucose such as seen in people with diabetes, the kidneys will flush more sodium and water out of the body, leading to lower chloride levels. A neutral pH is 7, which is the same pH as water.. Normally, the blood has a pH between 7.35 and 7.45. A blood pH of less than 7.35 is considered acidic, and ACID-BASE BALANCE a blood pH of more than 7.45 is considered alkaline. ARTERIAL BLOOD GASES The body has several mechanisms for maintaining blood pH. The lungs are essential for maintaining pH An arterial blood gases (ABG) test measures the and the kidneys also play a role.The lungs are acidity (pH) and the levels of oxygen and carbon dioxide in the blood from an artery. essential for maintaining pH and the kidneys also play a role. Example if your pH is too low (acidosis), the respiratory rate quickly increases to eliminate acid in the form of carbon dioxide, and the kidney excrete additional hydrogen ions or acid in the urine and retain bicarbonate. If pH is to high (alkalosis) , respiratory rate decrease to retain acid in the form of carbon dioxide and kidney excrete bicarbonate in the urine and retain hydrogen ions pH of our blood is Measure of hydrogen ion concentration.- byproduct of our metabolism substance such as protein fats and carbohydrates.
