Cardiac arrest & resuscitation
Recovery of arterial blood pressure after chest compression pauses in patients with out-of-hospital cardiac arrest
Authors' conclusion
ABP generated by mechanical CPR recovered quickly after pauses. Recovery of ABP after a pause was independent of pause duration.
Study context
- Population
- OHCA patients treated with mechanical chest compressions (LUCAS, 102 compressions/min) by an anesthesiologist-staffed rapid response car, Oslo, Norway (2015–2017), with arterial blood pressure (ABP) signal during cardiopulmonary resuscitation (CPR) and ≥1 compression pause >2 sec271 pauses
- Participants
- 56 patients
- Primary endpoint
- Recovery of ABP (compression, mean, decompression) after compression pauses and its relationship with pause duration
Methodological detailsprospective
- Prospective
Primary result
As reported in the abstract
- Pause duration, median (Q1–Q3)
- 11 sec (7–18 sec)
- Mean ABP, last pre-pause compression
- 53 ± 10 mmHg
- Mean ABP during pause
- 33 ± 7 mmHg
- Compression and mean ABP recovered to >90% of pre-pause pressure
- within 2 compressions, or 1.7 sec
- Pause duration did not affect ABP recovery post-pause (R2 compression, mean, decompression ABP)
- 0.05, 0.03, 0.01
