Overview
The first sentence of the overview must contain the name of the disease.
Causes
Life Threatening Causes
Life-threatening causes of Respiratory Alkalosis include
Common Causes
- Central Nervous System related causes:[1]
- Increased Intracranial Pressure
- Stroke
- Head injury
- CNS infection
- Intracranial hemorrhage
- Pontine tumors
- Anxiety Hyperventilation
- Voluntary Hyperventilation
- Sepsis(Cytokine mediated)
- Chronic Liver disease(Toxin mediated)
- Drugs(Salicylates, progesterone)
- Pain
- Hypoxemic causes: Hypoxic stimulation leads to hyperventilation.
- Pulmonary Causes:
- Extrinsic Causes(deliberate or iatrogenic):
- Excessive minute ventilation during mechanical ventilation
Diagnosis
Shown below is an algorithm summarizing the diagnosis of Respiratory Alkalosis:[2][3]
Patient with Acute Respiratory Alkalosis | |||||||||||||||||||||||||
Take complete history | |||||||||||||||||||||||||
Ask the following questions regarding CNS manifestations ❑If they felt dizzy or confused recently?
Light-headedness and Confusion due to reduced cerebral blood flow ❑Ask if they had experienced tremor of the hand when the wrist is extended, sometimes said to resemble a bird flapping its wings to check Asterexis ❑If there is any history of loss of consciousness ❑Ask about any event of seizues | |||||||||||||||||||||||||
Ask the following questions regarding Cardiovascular manifestations ❑Ask if they felt any chest discomfort or pain? Chest pain due to vasoconstriction❑If they felt their heart was racing? Ask about cardiac Arrythmia | |||||||||||||||||||||||||
Ask the following questions regarding Metabolic effects ❑Ask if they have experienced perioral tingling sensations ❑Tetany ❑Ask about any symptoms of mild hyponatremia, hypokalemia, and hypophosphatemia | |||||||||||||||||||||||||
Do complete physical examination | |||||||||||||||||||||||||
Vital signs ❑Decreased blood pressure(hypotension) due to hypoxemia ❑Orthostatic changes due to reduced plasma volume | |||||||||||||||||||||||||
Examination of respiratory system ❑Inspiratory crackles if patient has Pulmonary edema ❑Prolonged expiratory wheezing in patient with Asthma | |||||||||||||||||||||||||
Examination of Cardiovascular System ❑Irregular rhythm may be seen ❑palpable P2, right ventricular heave may be seen if patient has Pulmonary hypertension | |||||||||||||||||||||||||
Examination of Abdomen ❑Ascites in Liver disease ❑Gravid uterus in pregnany woman | |||||||||||||||||||||||
Examination of the Extremities ❑Cyanosis due to hypoxemia | |||||||||||||||||||||||||
Examination of Central Nervous System ❑Tremor, paresthesias ❑Chvostek’s and Trousseau’s signs due to Low ionized Ca2+ | |||||||||||||||||||||||
