1. Types of Ventilation
Ventilation support for individuals with amyotrophic lateral sclerosis (ALS) addresses the progressive respiratory muscle weakness characteristic of the disease. Selecting the appropriate type of ventilation is a critical decision, influenced by the stage of the disease, individual needs, and personal preferences. Understanding the available options is crucial for both patients and caregivers.
-
Non-Invasive Ventilation (NIV)
NIV, typically delivered via a mask interface (nasal, oronasal, or total face), provides ventilatory support without the need for a tracheostomy. NIV can be used intermittently or continuously, depending on the individual’s needs. It is often the first line of respiratory support and can effectively manage symptoms like shortness of breath and sleep-disordered breathing. NIV improves sleep quality, reduces daytime fatigue, and can prolong survival. However, it may not be suitable for all individuals, particularly those with bulbar weakness or difficulty tolerating the mask interface.
-
Invasive Mechanical Ventilation (IMV)
IMV involves a tracheostomy, a surgical procedure creating an opening in the trachea, through which a ventilator delivers air directly to the lungs. IMV provides complete control over breathing and is generally considered when NIV is no longer effective or appropriate. While IMV offers greater respiratory support, it requires more intensive care and carries a higher risk of complications, such as infections. The decision to transition to IMV is complex and involves careful consideration of the individual’s overall health and preferences.
-
Volume-cycled ventilation
This mode delivers a preset volume of air with each breath, ensuring consistent lung inflation regardless of airway resistance. It’s particularly useful in conditions where lung compliance changes, offering stable ventilation. While effective, volume-cycled ventilation might require adjustments based on patient response and can potentially lead to overinflation if parameters are not carefully monitored.
