Answer

Peak flow in nursing refers to the maximum speed at which a patient can exhale air from their lungs. It is measured using a device called a peak flow meter.

This measurement is particularly important for patients with respiratory conditions like asthma. Monitoring peak flow helps assess the severity of airway obstruction and the effectiveness of treatment. A drop in peak flow can indicate that a patient's asthma is worsening, even before they experience noticeable symptoms.
