Non-invasive management of an acute chest infection for a patient with ALS.
2003
We describe a man diagnosed with non-bulbar amyotrophic lateral sclerosis (ALS) who uses 24-h non-invasive ventilator at home, and assisted cough through the use of the mechanical insufflation-exsufflation (MAC) device (CoughAssist, J.H. Emerson). This was essential for the removal of bronchial secretions in order to provide successful non-invasive management (and indeed less suffering for the patient) during an acute respiratory tract infection with hypoxemia and failure of manually assisted cough.
Mechanical insufflation-exsufflation vs. tracheal suctioning via tracheostomy tubes for patients with amyotrophic lateral sclerosis: a pilot study.
2003
To compare the effects of mechanical insufflation-exsufflation vs. suctioning via tracheostomy tubes on respiratory variables for six amyotrophic lateral sclerosis patients.In this prospective crossover study, six consecutive patients with amyotrophic lateral sclerosis who required continuous mechanical ventilation via tracheostomy tubes and developed chest infections underwent measurement of pulse oxyhemoglobin saturation (SpO2), peak inspiratory pressure (PIP), mean airway pressure (Pawm), and work of breathing performed by the ventilator (WOBv) at baseline and 5 and 30 min after tracheal suctioning and 5 min after mechanical insufflation-exsufflation.The baseline values were 93.50 +/- 2.…
Effect of High-Frequency Oscillations on Cough Peak Flows Generated by Mechanical In-Exsufflation in Medically Stable Subjects With Amyotrophic Later…
2016
BACKGROUND: Mechanically assisted coughing with mechanical in-exsufflation (MI-E) is recommended for noninvasive management of respiratory secretions in amyotrophic lateral sclerosis (ALS). To improve the effectiveness of the technique, a new device combining MI-E with high-frequency oscillations (HFO) has been developed. This work aimed to assess the effect of HFO on the cough peak flow generated by MI-E in medically stable subjects with ALS. METHODS: This was a prospective study that included subjects with ALS in a medically stable condition. Cough peak flow generated by MI-E was measured in 4 situations: without HFO, with HFO during insufflation, with HFO during exsufflation, and with HF…
Efficacy of Mechanical Insufflation-Exsufflation in Medically Stable Patients With Amyotrophic Lateral Sclerosis
2004
Objective: To determine under what circumstances the use of mechanical insufflation-exsufflation (MI-E) can generate clinically effective expiratory flows for airway clearance (> 2.7 L/s) for clinically stable patients with amyotrophic lateral sclerosis (ALS). Materials and method: Twenty-six consecutive patients with ALS were studied, 15 with severe bulbar dysfunction. Using a pneumotachograph and with the aid of an oronasal mask, we measured FVC, FEV1, peak cough flow (PCF), maximum insufflation capacity (MIC), PCF generated from a maximum insufflation MIC (PCFMIC), and PCF generated by MI-E (PCFMI-E). MI-E was delivered at 40 cm H2O. Maximum inspiratory pressure (PImax) and maximum expir…
Usefulness of Oscillations Added to Mechanical In-Exsufflation in Amyotrophic Lateral Sclerosis.
2019
BACKGROUND: Assisted coughing via mechanical in-exsufflation (MI-E) is a first-line treatment for secretion management in patients with amyotrophic lateral sclerosis (ALS) with unassisted CPF METHODS: We conducted a 12-month, prospective, randomized follow-up study of subjects with ALS for whom assisted coughing techniques were indicated. One group was treated with oscillations in addition to MI-E (MI-E+O), and the other group was treated with conventional MI-E. RESULTS: 29 subjects were included in the MI-E group and 27 subjects were included in the MI-E+O group. Five subjects (8.9%) required invasive techniques for secretion management (3 in the MI-E group and 2 in the MI-E+O group, P = .…
Mechanical Insufflation-Exsufflation With Oscillations in Amyotrophic Lateral Sclerosis With Home Ventilation via Tracheostomy
2020
BACKGROUND: Mechanical insufflation-exsufflation (MI-E) applied via tracheostomy tubes in patients with amyotrophic lateral sclerosis (ALS) who are on home mechanical ventilation via tracheostomy is an effective procedure for respiratory secretion management. Nonetheless, tenacious secretions may remain and increase the risk of respiratory infections. The aim of this study was to determine whether adding oscillations to MI-E could reduce the rate of respiratory infections and the need for bronchoscopy to remove secretions in patients with ALS on home mechanical ventilation via tracheostomy. METHODS: This was a 2-y, prospective, crossover study. Subjects were treated with conventional MI-E a…
