When suctioning blood from the trachea using a bronchoscope, a sudden loss of suction pressure can indicate an issue within the suctioning system. Checking the suction channel on the bronchoscope is vital because the suction channel is what allows for proper drainage and suctioning. If there is a blockage in this channel—whether due to tissue debris, blood clots, or other obstructions—it can lead to a loss of suction pressure at the end of the scope.

By examining the suction channel, the respiratory therapist can determine if there is an obstruction that needs to be cleared or if the channel is functioning properly. Ensuring the suction channel is unobstructed is crucial for maintaining proper suctioning capabilities during the procedure.

Other components, such as the suction pressure at the wall or integrity of the suction line, while important in the overall function of the suction system, would not directly affect the suction pressure at the distal end of the bronchoscope if the channel itself is compromised. Thus, focusing on the suction channel is the most relevant and immediate action to address the issue of lost suction.
