Respiratory considerations in patients with neuromuscular disorders

Area of Science:

• Neurology
• Pulmonology
• Respiratory Medicine

Background:

• Neuromuscular disorders (NMDs) progressively weaken respiratory muscles.
• This leads to reduced lung function, impaired cough, and increased infection risk.
• Sleep disordered breathing is common due to muscle weakness or central control issues.

Purpose of the Study:

• To outline the respiratory complications in NMDs.
• To describe evaluation methods for respiratory impairment.
• To discuss management strategies and technological advancements in respiratory support.

Main Methods:

• Assessment of seated and supine vital capacity (VC).
• Measurement of respiratory muscle strength.
• Evaluation of cough effectiveness and sleep studies.

Main Results:

• Respiratory muscle weakness significantly impacts lung function and airway clearance.
• Noninvasive ventilation is preferred for mobility and independence.
• Tracheostomy is reserved for severe bulbar impairment and failed cough assistance.

Conclusions:

• Technological advancements in respiratory support enhance quality of life and survival in NMD patients.
• Home care is optimal but presents significant challenges for caregivers.
• Multifactorial decisions guide the initiation of assisted ventilation.
