Method and system to detect arterial blood pressure damping and to perform automated fast flushing of the catheter-tubing

An arterial blood pressure management system, comprising:

• a pressure sensor receptor configured to receive an arterial blood pressure signal detected by a pressure sensor;
• and
• an arterial blood pressure monitor communicatively coupled to the pressure sensor receptor, the arterial blood pressure monitor being configured to:
• determine whether an arterial blood pressure signal damping event is occurring based on the arterial blood pressure signal,
• transmit an instruction to an electronically controllable valve to control the valve to automatically flush a catheter tubing in response to a determination that the arterial blood pressure signal damping event is occurring,
• determine whether the arterial blood pressure signal damping event is resolved in response to the automatic flush of the catheter tubing based on the arterial blood pressure signal, wherein the determination that the arterial blood pressure signal damping event is occurring is based on a first criterion and a determination that the arterial blood pressure signal damping event is resolved is based on a second criterion that is different than the first criterion,
• determine, with regard to the first criterion, whether the arterial blood pressure signal damping event is occurring based on a pattern change of the arterial blood pressure signal within a specified time window and beyond one or more specified threshold value, and
• determine, with regard to the second criterion, whether the arterial blood pressure signal occurring before a specified pre-flush time window compared to the arterial blood pressure signal occurring after a specified post-flush time window goes beyond one or more specified flush effectiveness threshold values, where in the one or more specified flush effectiveness threshold values comprises a systolic arterial blood pressure threshold value, a pulse arterial blood pressure threshold value, and an arterial blood pressure waveform slope threshold value.
