Oxygen is vital for the well being of the mother and the fetus. Every pregnant woman needs a proper treatment to maintain normal lung functions and oxygen level to maintain proper oxygen supply to the fetus.

Asthma patient should receive education about maintenance and rescue medication, how to measure PEFR by peak flow meter, proper use of inhalers, asthma prevention, and adherence of asthma action plan. Patient should also learn when the asthma is worsening and when to contact the doctor.

Spirometry is the preferred method for pulmonary function testing during outpatient visits. However, peak expiratory flow measurement with a peak flow meter is also adequate.

Individualized pharmacotherapy to maintain normal pulmonary functions.
