How to diagnose and treatment- clinical examination. Refer to physician with non-traumatic chest pain. Lab tests can tell if viral or bacterial infection. Chest X-ray may reveal pneumonia or mass. Chest CT can show underlying lung disease. Ultrasound can detect fluid. Treating underlying conditions, NSAIDs, antibiotics if bacterial. Recovery depends on underlying illnesses but usually good with treatment.

internal intercostal muscles

group of skeletal muscles located between ribs

external intercostal muslces

outer layer of muscles between ribs

diaphragm

dome shaped muscular partition separating the thorax from the abdomen in mammals. Plays role in breathing

explain the physiological process of ventilation

Chemoreceptors in medulla oblongata sense changes in pH and carbon dioxide levels. Decrease in pH and increase in carbon dioxide result in increase in ventilation. Neural control of breathing comes from phrenic nerve which innervates diaphragm. Diaphragm and intercostal muscles contract, and thoracic cavity expands. This generates negative pressure, which causes air to go into the lungs during inspiration. When alveolar pressure equalizes with atmospheric pressure, intercostal receptors fire and inspiration ceases. Elastic recoil of the thoracic cage results in passive process of expiration.

Describe the four common chest shapes and any common pathology that may be associated with each

Normal chest- thorax is elliptical and is narrower anterior to posterior than it is across the transverse axis Barrel chest- rounded shape that is the same diameter from anterior to posterior as it is transversely. Chronic emphysema and asthma Pectus excavatum- congenital shape, not symptomatic, presents with a depression at the junction of the xiphoid with the sternum. Pectus carinatum- forward protrusion of the sternum

Describe the three methods in which the body maintains its acid-base balance

Respiratory Buffer works by increasing or decreasing CO2 by ventilation until its at the proper level. Can compensate in one to three minutes. The Renal Buffer works by retaining or excreting HCO3-. Can take hours or days to compensate. The buffer system helps to compensate and keep the body’s pH in the normal range.

What is the body's normal pH?

7.34-7.45

respiratory acidosis

pH less than 7.35 and PaCO2 is greater than 45 mm Hg. Caused by accumulation of CO2 which produces carbonic acid which lowers the pH of the blood. Can occur form central nervous system depression from head injury, medications, sedatives, anesthesia. Impaired respiratory function from injury and disease, pulmonary disorders such as atelectasis, pneumonia, massive pulmonary embolus, and hypoventilation.

respiratory alkalosis

pH is greater than 7.45 and PaCO2 is less than 35 mm Hg. Caused by hyperventilation which could be anxiety, fear, pain, increased metabolic demands, medications, central nervous system lesions.

metabolic acidosis

Bicarbonate level less than 22 mEq/L with pH less than 7.35. Caused by deficit of base in bloodstream or excess of acids. Diarrhea and intestinal fistulas may decrease base. Renal failure, diabetic ketoacidosis, anaerobic metabolism, starvation, and salicylate intoxication may increase acids.

metabolic alkalosis

Bicarbonate level greater than 26 mEq/L and pH greater than 7.45. Either excess base or acid in the body. Excess base is from antacids, excess use of bicarbonate, use of lactate in dialysis. Loss of acids can occur secondary to vomiting, gastric suction, hypochloremia, excess diuretics, high levels of aldosterone.
