In people whose asthma is caused by workplace conditions, improved ventilation or face masks may help, but often even low levels of chemical agents can trigger a response. In such cases, leaving the job is the only way to prevent the condition from getting worse, especially because increased exposure to asthma triggers in the workplace worsens the condition. This can often be a severe emotional and financial hardship, and workers should be sure occupational substances are the cause by having a complete check-up by a lung specialist. If the diagnosis of occupational asthma is certain, patients should obtain advice on available compensation plans for disability. Monitoring People who self-manage their asthma using daily monitoring of peak air flow and adjusting their medications as needed have fewer hospitalizations, unplanned doctor's visits, and, generally, a better quality of life than those who rely only on the occasional physician or emergency room visit to control symptoms.
Physicians recommend that patients with even mild asthma monitor their own conditions.
A peak flow meter is the standard monitoring device. Some recommend taking readings two or three times a day, although for mild to moderate asthma, a single determination each morning usually suffices. It is important to use the meter at the same times each day and to stand or sit in the same position in order to keep an accurate record. Patients should keep an ongoing record of their peak flow readings to help them detect worsening of their condition. They should also record attacks, exposure to any allergens or triggers, and medications taken.
