Philips Respironics CoughAssist T70

Philips Respironics CoughAssist T70. Peak cough flow: -30 cmH20 (Exhale 2.0 sec). Tidal volume: +30 cmH20 (Inhale 3.0 sec). This device is in standby mode. It's designed to assist with cough function. It needs the power cable & masks. I was able to turn it on because i used my own power cable... So aside from it turning on , the power cable would have to be bought too...
