Abstract
dc.description.abstract
Cough is a natural reflex that protects respiratory airways against infections
or mucus retention. Cough maintains an adequate cleaning of the airways and is
a mainstay of respiratory therapy. It can be triggered voluntarily by the patient
or by a specific cough device. Peak cough flow (PCF) is used to assess the effectiveness
of the cough. When this value is below 160 L/min, cough is considered
inefficient and becomes a risk factor for respiratory problems. Patients with weak
cough, especially those with neuromuscular disease, have in common a low tidal
volume and a decreased maximum insufflation capacity. Both factors directly
affect the inspiratory phase previous to cough, which is considered vital to obtain
the optimum flow for a productive cough. Different therapeutic measures may
help to increase cough efficiency among patients with cough weakness. These
interventions may be performed using manual techniques or by mechanical
devices. The aim of this review is to analyze the different techniques available
for cough assistance, set a hierarchy of use and establish a scientific basis for their
application in clinical practice.
