It was reported that the device's inlet pressure increased to over 150 psi.There was no patient involvement when the event occurred, no patient or user harm reported.Per the diagnostics performed by the engineer, the customer stated receiving an error for an o2 inlet pressure being too high.It was reported that the device was at 73 psi, then slowly increased to 150 psi.The remote service engineer indicated that the issue could be from trapped o2 pressure between the manifold and the o2 inlet.The customer disconnected the o2 source and verified the o2 inlet pressure.It was reported that when the o2 was disconnected, the o2 inlet went down to 0.2 psi.After reconnecting the o2 source, the o2 inlet pressure started at 50 psi, and after 30 seconds, it went up to 90 psi.It was verified that the o2 solenoid valve was operating properly.The customer reported that they would test a different v60 ventilator with the same set up, to try and verify that the h tank was operating fine.The customer verified the regulator on top of the h tank was defective and caused the high 2 inlet pressure readings.The customer used a different o2 source, and the device operated as intended.
