Case 1

When the patient was in the emergency department what pulmonary function measurement served as an important clinical indicator of the severity of the patient's asthma attack?

Summary Introduction

To review:

The pulmonary function measurement that serves as an important clinical indicator of the asthma attack severity.

Introduction:

Apart from measuring the capacities and volumes, the rate of the flow of gases is also measured. They provide data about the integrity of the airways, problems of the small and large airways, and the severity of the impairment of airways. All these tests are known as the pulmonary mechanic measurements.

Please refer to Clinical Application Case-1 for further information.

Explanation

In the given case, it is shown that the pulmonary mechanism of the patient can act as a clinical monitor during a forced expiratory maneuver. The personal best PEFR, which is determined by the patient at home, helps to evaluate the severity of the asthma attack.

Another term used for PEFR (peak expiratory flow rate) is the peak flow rate, which can be defined as the maximum rate of flow that can be achieved during FVC (forced vital capacity) maneuver. It is measured using a device known as the peak flow meter.

It reflects the initial flow of the air, which originates from the large airways during the first part of FVC...
