During the transport of a patient being ventilated with a Newport HT50 ventilator, the low air-way pressure/apnea indicator begins to blink red and the "check proximal line" alarm is triggered. What is the most appropriate action?
a. Suction the pa-tient's airway. c. Check the circuit's integrity.
b. Increase the pres-sure limit. d. Switch the mode of ventilation.
ANS: C
The "check proximal line" alarm occurs during inspiration when the proximal pressure measured is significantly different from the internal backup pressure sensor measurement taken inside the ventilator. In addition to the message, the low airway pressure/apnea indicator blinks red. Causes include disconnections, kinking of the circuit, and a water-filled proximal sensor line.
