Noninvasive Ventilation Support in ALS

• Primary Goal: To provide respiratory assistance without the need for invasive procedures like tracheostomy, thereby improving quality of life and survival in Amyotrophic Lateral Sclerosis (ALS).
• BiPAP (Bilevel Positive Airway Pressure): The standard and most widely used noninvasive support, delivering two levels of pressure—higher pressure during inhalation and lower pressure during exhalation to assist failing respiratory muscles.
• Continuous Positive Airway Pressure (CPAP): Generally less suitable for ALS patients compared to BiPAP because it provides a single pressure level, making it harder to exhale against weakened chest muscles.
• In-Exsufflator (Mechanical Cough Assist): Often used in conjunction with ventilation support to help clear mucus and secretions from the lungs when the cough reflex becomes weak.
• Oxygen Therapy Cautions: Supplemental oxygen must be used with extreme caution and under strict medical supervision in ALS patients, as it can sometimes suppress the natural respiratory drive and lead to increased carbon dioxide retention.
