bases to maintain homeostasis pH indicates the concentration of hydrogen ions in the blood Respiratory and metabolic processes work to keep hydrogen ion (H+) levels stable Normal pH of arterial blood is 7.35 – 7.45 (slightly alkaline or basic) pH of less than 7.35 indicates acidosis (high H+) pH of more than 7.45 indicates alkalosis (low H+) 2 ABG Analysis pH is affected by carbon dioxide on respiratory side CO2 will combine with water in blood to form carbonic acid (CO2 + H2O = H2CO3) CO2

Respiratory Acidosis and Alkalosis Activity 1: Normal Breathing 1. At 20 seconds‚ pH = 7.4 2. At 40 seconds‚ pH = 7.4 3. At 60 seconds‚ pH = 7.4 4. Did the pH level of the blood change at all during normal breathing? If so‚ how? The pH did not change during the normal breathing. 5. Was the pH level always within the “normal” range for the human body? Yes it was. 6. Did the PCO2 level change during the course of normal breathing? If so‚ how? No it did not change either.

PATHOPHYSIOLOGY FOR THE HEALTH PROFESSIONS CHAPTER 6: FLUID‚ ELECTROLYTE‚ AND ACID-BASE IMBALANCES Fluid Imbalance Review of Fluid Imbalance -Water carries nutrients into cells and removes wastes‚ transports enzymes in digestive secretions‚ and moves blood cells around the body. Fluid Compartments -Approximatley 60% of an adult’s body weight consists of water -Infant’s body weight is about 70% -Fluid is distributed between the intracellular compartment (ICF)‚ or fluid inside the

accomplished mainly through respiratory control‚ and the kidneys also play a small role. False Severe damage to the respiratory system rarely will result in acid-base imbalances. False Respiratory acidosis results when lungs are obstructed and gas exchange is inefficient. True Prolonged hyperventilation can cause alkalosis. True Thirst is always a reliable indicator of body water need. False Blood acidity results in depression of the CNS‚ whereas blood alkalosis results in overexcitement of

Describe how the kidneys regulate hydrogen and bicarbonate ion concentrations in the blood. 17. Distinguish between acidosis and alkalosis resulting from respiratory and metabolic factors. Describe the importance of respiratory and renal compensations to acid-base balance. Developmental Aspects of Fluid‚ Electrolyte‚ and Acid-Base Balance

Task 4 – The Maintenance of the Acid – Base balance in the body (D1) pH is measured based on its acidity and alkalinity. There are many substances around the body that have different pH values. A pH of 7 is usually considered neutral‚ neither acid nor alkaline‚ this is the pH of water. In the body the acids and bases need to be in very close balance‚ this is called ‘acid base homeostasis. If it goes off too far in either direction then it could be fatal to the body. For example in the body the blood
