Root Cause

Air bubbles > 0.5 mL in IV lines can cause venous air embolism, leading to pulmonary obstruction, cardiac arrest, or stroke if air enters arterial circulation via patent foramen ovale.

静脉输液管中大于0.5毫升的气泡可导致静脉空气栓塞，引起肺阻塞、心脏骤停，或通过卵圆孔未闭进入动脉循环导致中风。

Workarounds

  1. 95% success If air is in IV tubing: clamp line immediately, disconnect from patient, prime new tubing using aseptic technique, and reconnect. For central lines: place patient in Trendelenburg position (head down) to trap air in right atrium.

  2. 92% success Use in-line air detectors on infusion pumps: set alarm threshold to 0.1 mL. Example pump setting: `Air Detector: ON, Threshold: 0.1 mL, Action: STOP infusion` 
    Use in-line air detectors on infusion pumps: set alarm threshold to 0.1 mL. Example pump setting: `Air Detector: ON, Threshold: 0.1 mL, Action: STOP infusion`

Dead Ends

Common approaches that don't work:

  1. 80% fail

    Nurse believes small bubbles dissolve in blood harmlessly; but rapid infusion or central lines make even small bubbles dangerous

  2. 60% fail

    Nurse thinks tapping the drip chamber will clear all air without disconnecting
