A 49-year-old woman presents to the ED with difficulty breathing after a morning jog. Her initial vitals are stable with an oxygen saturation of 94% on room air. Upon physical examination, the patient appears to
be in mild distress with audible wheezing. She is able to speak in partial sentences and states that she occasionally uses an inhaler. Given this patient’s history and physical examination, which of the following measures should be taken next?
a. Peak expiratory flow
b. Chest radiograph
c. β-Natriuretic peptide level
d. temperature
e. ABG

This patient is suffering from an exercise-induced asthma exacerbation. The medical intervention in this patient should include a β2-agonist nebulized solution, corticosteroids, and oxygen administration. The most useful measure to track the patient’s progress with each treatment is a peak expiratory flow, and should be a part of the initial assessment and monitoring

Probably the woman is suffering from an acute asthmatic attack n hence her peak expiratory flow if known will be diagnostic of her current status.

oxygen saturation of 94% on room air,so need to do ABG. pt with audible wheezing should get CXR.Peak expiratory flow helpful in asthma pts.

Tests for bronchial asthma may include:
Arterial blood gas
Blood tests to measure eosinophil count (a type of white blood cell) and IgE (a type of immune system protein called an immunoglobulin)
Chest x-ray
Lung function tests
Peak flow measurements to categorise the asthma

In a patient with features of bronchial asthma, Peak expiratory flow and its improvement with bronchodilators should be tested to classify the asthma for further treatment
