Question

CASE STUDY 17.8 A 23-year-old woman with a history of brought to the emergency department by aa extremely short of breath. Her level ofcon questions with nods or one-word responses. She had a of asthma was ambulance. She yma hwas diminished greatly, and she was only able to ou a cough, with nearly inaudible breath sounds. After dra respond t blood gases, she was placed on supplemental oxygen. V signs: heart rate, 160 bpm; blood pressure, 120/84 mm H d temperature, 37°C, and respiratory rate, 36/min. Her inital e blood gas and total hemoglobin results were as follows: pH pcO2 pO2 HCOs tHb 7.330 25 mm Hg 58 mm Hg 13 mmol/L 12.4 g/L Questions 1. What is the patient's acid-base and oxygenation status What is the cause of the acid-base disturbance? 3. Estimate how long it may take for the patient to partilly and then fully compensate for the acid-bas dysregulation

Answer 1

1, patient PH level decrease to 7.330(normal range between (7.35 to 7.45) it results in acidemia due to less serum hydrogen ion concentration.
Pco2 normal range 35 - 45...patient having less Pco2 level 25 mmHg, its decreased. There is respiratory compensation for metabolic acidosis.
Hco3 decrease to 13mmol/l, so there is renal compensation taking place for metabolic acidosis
tHb is normal, so the patient is having metabolic acidosis. when there is Hco3 reduced there will be a compensatory reduction in co2 partial pressure(pco2)
2, When there is high co2 retention in the body results acidic state. when there is airway obstruction(asthma) they can not get rid of enough of co2.
3, Hypoxia is a part of the interpretation process. lungs and kidney are the primary buffer system in the hemostatic process. compensation when the patient begins to when the co2 reaches normal in the blood.. when the patient having a metabolic disorder there may need hyperventilation. respiratory compensation in metabolic disorder reach to the maximum value within 24 hours...complete compensation occurs when PH disturbance need the kidney to change plasma (Hco3). Acute compensation or partial compensation occurs within 6 -24 hours and chronic or fully compensation occur within 1 to 4 days, respiratory compensation occurs faster than metabolic compensate.
