  • Breathing Patterns Breathsounds
    By Breathing Patterns BreathSounds Breathing isn’t just a matter of inhaling the good air and exhaling the bad used air. The entire respiratory pattern is important. Rate, depth, timing, and consistency of breaths are all important to the delicate balance of respiration and metabolism. Certain illnesses or injuries can cause changes in the breathing pattern. Changes other than the typical fast or slow breathing that is most common with many conditions. Below are some of the less common breathing patterns that make many healthcare professionals ask themselves… “Hey, what is that pattern anyway?” Breathing Patterns: 1. Cheyne-Stokes respirations a. Definition: This respiratory pattern is characterized by periods of respirations during which the tidal volume starts shallow and gets progressively deeper, and then gets progressively shallower. This shallow-deep-shallow pattern is followed by periods of significant apnea that can last up to 30 seconds or longer, then the cycle starts over. Each cycle can take anywhere between 30 seconds and 2 minutes or longer. b. Causes: This pattern of respiration is often caused by strokes, traumatic brain injuries, brain tumors, carbon monoxide poisoning, and metabolic encephalopathy. This pattern of respiration can be seen in healthy patients experiencing first-time high altitude sickness, and can also be a normal side-effect of morphine administration. 2. Biot’s breathing (aka cluster respiration) a. Definition: A respiratory pattern characterized by periods or “clusters” of rapid respirations of near equal depth or VT followed by regular periods of apnea. b. Causes: Biot’s breathing can be caused by damage to the medulla oblongata by stroke (CVA) or trauma, pressure on the medulla due to uncal or tentorial herniation.

Blood Work Blood Urea Nitrogen Creatinine Serum Electrolytes Hgb & Hct Serum Albumin Serum Osmolality Blood Urea Nitrogen: BUN: 5.0 – 25 mg/dL Urea is formed in the liver along with C02 as a waste by product of protein metabolism. It is carried by the blood and excreted by the renal system. Elevated BUN levels are significant for either increased protein catabolism or decreased renal excretion of urea. Situations, which would increase protein catabolism, include high protein diets, GI bleeding (protein from blood is broken down), DKA, burns and cancer. Any pre-renal (shock state, poor renal perfusion) or intra-renal failure (nephrotoxic medications or kidney diseases) will decrease the GFR and therefore urea excretion. The elevation of the metabolic waste products can cause fatigue, muscle weakness, and seizures. Volume status of the patient can also affect the BUN. Treatment is related to the cause of the elevation, which would include hydration, stopping protein catabolism, and/or dialysis. 187 Creatinine: 0.6 – 1.5 mg/dL slightly lower in females, children and elderly Creatinine is a waste product of creatinine phosphate breakdown. Creatinine phosphate is a high-energy compound found in skeletal muscle tissue and is released during muscle breakdown.
