Astral 100, Ventilator

Once Steve’s FVC fell below 50%, he was prescribed a noninvasive ventilator (NIV). He was issued an Astral 100. We found this ventilator easy to use and manage.

Description

Steve started using this primarily at night. When he struggled to breathe more, he would use it periodically throughout the day. He would get his breathing “fix” or reset.

Eventually, he used it more during the day. He would take it off to eat and brush his teeth. Through his decline he found ways to work, present, and record videos. He also walked both of his daughters down the aisle. By late 2024, he was on the NIV 24 hours a day. He consumed a lot of energy and brain power focused on breathing. This huge amount of stress went away when he got his tracheostomy.

We bought an external battery and carry case through someone in an ALS group. This battery gave us more security as we traveled around. The carry case made it easier to hang on the power chair. Overall, we were very happy with the Astral system.

Backup power is essential when your basic needs like breathing require a machine. Most of the equipment we use has battery power like our ventilator and our lifts. The onboard power is usually sufficient but typically only lasts 4 – 8 hours depending on usage. But we wanted to be prepared for power outages and travel.

We had a situation where Steve’s NIV ran out of battery power at an event. We were able to get it plugged in, but it was going to take hours to charge before we could go home safely. Friends and family jumped into help. Our friends got us the Ryobi battery solution and our son in law brought our large generator from home about an hour away. We got home safely, and the importance of backup power was reinforced.
