Nội dung Text: Bài thuyết trình tiếng Anh đề tài: Respiratory Acidosis

Respiratory Acidosis Done by : Ibrahim Ali Al-Sayegh ID# 2021040084 Supervised by : Dr. Ibrahim Saeed
RESPIRATORY ACIDOSIS Definition:  A Primary increase in arterial PaCO2 leading to decrease in arterial pH .  It could be Acute or Chronic
: Causes Either :  alveolar hypoventilation Or  V/P mismatching
Alveolar hypoventilation : Respiratory Center suppression-1 Can be suppressed by many factors like : drugs Neuromuscular Junction : Ex : mysthenia gravies-2 Respiratory Muscles: Ex : myopathy-3 Pleural Cavity: Ex : pneumothorax-4 :Lung Parenchyma and Airways-5 ( Ex: obstructive lung disease ( BA & COPD Alveolar hypoventilation
V/P mismatching  pulmonary embolism  Pneumonia  Acute respiratory distress syndrome  Collapsing of alveoli  fibrosis
Ventilation Perfusion Mismatching
Alveolar Hypoventilation
RESPIRATORY ACIDOSIS The Value of “A-a” Gradient:  Calculation: 1. paCo2 X 1.2 = X 2. 150 – X = “A” 3. A (alveolar O2) – a (arterial O2) = A-a gradient.  Normal A-a Gradient = Up to 15 mmHg.  High A-a Gradient Vent Perfusion mismatching.  Normal A-a Gradient Alveolar Hypoventilation.

: Clinical manifestation  Signs and symptoms are related to the degree and duration of respiratory acidosis .  Precipitous rise in PCo2 can lead to :  Confusion , anexity , psychosis , flapping tremor , seizure .  Signs of catecholamines release : diaporesis , increase heart rate and high cardiac output, flushing.  Coma in PCo2 > 60 mmHg ( Co2 narcosis)  Signs of chronic hypercapnia :  Fatigue , lethargy in addition to finding in acute hypercapnia .
: Treatment  Treatment of repiratory acidosis aimed primarily at :  Correction of underlying cause ( COPD,asthma, pulmonary embolism ….)  And  Ensuring adequate ventilation
: Roles in management  in management of patient with respiratory acidosis >>> we don’t give him 100% oxygen to not suppress the respiratory center .  Also , sedatives , narcotics are contraindicated unless we will put the pt. on ventilator .  Bicarbonate therapy considered when PH fall below 7.1  Rapid and complete correction may lead to posthypercapnic alkhalosis > specially in patient with chronic respiratory acidosis .
