Arterial blood gas analysis was pH:7.3, PaCO2:55 mmHg, PaO2:75 mmHg, HCO3-:30 mEq/L. Respiratory rate:30 times/min, conscious, blood pressure and other vital signs are stable. Which of the following treatments is not suitable?

Explanation: 

Detailed explanation-1: -ICD-10 code: J44. 1 Chronic obstructive pulmonary disease with acute exacerbation, unspecified.

Detailed explanation-2: -An arterial blood gas test is one of the tests used for COPD diagnosis. The test measures the oxygen (O2) level in your blood and if carbon dioxide (CO2) is removed properly. It can also determine the acidity (pH) of your blood.

Detailed explanation-3: -Emergency Department Care in COPD In addition to oxygen, proper ED care may comprise bronchodilators, antibiotics, magnesium, CPAP or biphasic positive airway pressure (BiPAP), Heliox (ie, mixture of helium and oxygen), and definitive airway management via intubation.

Detailed explanation-4: -Oxygen therapy. Some people with COPD use oxygen only during activities or while sleeping. Others use oxygen all the time. Oxygen therapy can improve quality of life and is the only COPD therapy proved to extend life.
