Overview
Laboratory findings consistent with the diagnosis of respiratory failure include abnormal bicarbonate, oxygen, phosphate, and magnesium levels.
Laboratory Findings
- Laboratory findings consistent with the diagnosis of respiratory failure include:[1]
- Arterial blood gases
- Bicarbonate may be elevated to more than 45mmHg, and oxygen levels below 60mmHg
- Electrolyte studies
- Low phosphate and low magnesium
- Toxicology screen for detection of:
- Opiates
- Benzodiazepines
- Tricyclic antidepressants
- Barbiturates
- Complete blood count
- Chronic hypoxemia may be associated with polycythemia
- Eosinophilia may be associated with eosinophilic myalgia
- Thyroid function tests
- An elevated TSH and decreased T4 indicates hypothyroidism
- Creatine phosphokinase may be elevated and may indicate:
- Infectious or autoimmune polymyositis
- Hypothyroidism
- Rhabdomyolysis secondary to colchicine or chloroquine toxicity
- Procainamide myopathy
- Arterial blood gases
