Paramedic research, 31 October 2026
Cardiac arrest led the day: real-time BVM feedback saw ventilations meeting both rate and volume targets rise from 7.5% to 39%, and dual-registry data confirmed women still receive less bystander CPR in public.

Real-time BVM feedback linked to better arrest ventilation
A US prospective before/after study in Milwaukee found real-time BVM feedback (Real BVM Help) was associated with the share of OHCA ventilations meeting both rate and tidal-volume targets rising from 7.5% to 39.0%.
-
Women still get less bystander CPR in public
A retrospective cohort of 10,445 public out-of-hospital cardiac arrests in North Carolina and Singapore found women were less likely to receive bystander CPR in both regions (aOR 0.87 and 0.78), with survival favouring women in North Carolina but men in Singapore.
-
Adrenaline timing not tied to paediatric OHCA survival
A Japanese national registry study of 259 witnessed paediatric out-of-hospital cardiac arrests given adrenaline, using time-dependent propensity matching to address resuscitation-time bias, found no adrenaline timing window was associated with better one-month survival or neurological outcome.
-
ECG signs appear minutes before post-ROSC rearrest
A US retrospective cohort of 1,298 post-ROSC OHCA patients found routine ECG features — wider QRS, lower heart rate, higher heart-rate variability — were associated with rearrest, with prediction best one minute before it (AUROC 0.74).
-
Severe hypertension in pregnancy rarely treated to guideline
A US national EMS dataset study of 39,546 responses for pregnant patients beyond 20 weeks found persistent severe hypertension in 3.1%, of whom only 0.8% received guideline-adherent treatment with both magnesium and an antihypertensive.
-
Few heat-stroke cooling devices suit the prehospital setting
A US systematic review of 18 commercial heat-stroke cooling devices found only three reached the ideal prehospital cooling rate (at least 0.155°C/min) and just five met single-person portability, with most relying on water, power or disposables.
-
AI ECG model excludes ACS after cardiac arrest
A South Korean single-centre study built an AI-assisted ECG decision tree that classified about half of post-OHCA patients as 'ACS not likely' with no adjudicated ACS case misclassified in development or temporal validation.
-
Ambulance infection control hinges on human factors
An Australian modified nominal group technique with ten experts ranked human factors — organisational culture, compliance fatigue, inconsistent education — above equipment provision as the main drivers of infection prevention and control compliance in ambulances.
-
Community paramedicine cut hospital admissions in cluster RCT
A Canadian cluster-randomised trial across 30 low-income apartment buildings found the CP@clinic community paramedicine program was associated with lower hospital admission rates during (aIRR 0.75) and after (aIRR 0.82) the trial, with no difference in ED visits.
-
Simulated EMS care held up at altitude
In a Swiss randomised crossover simulation study, 20 non-acclimatised EMS physicians showed no significant drop in overall performance at 3,450 m altitude (composite 82% at baseline vs 74% acute exposure, p=0.082).
-
Swedish bleeding control guidelines scored low on quality
A Swedish cross-sectional appraisal of regional prehospital bleeding-control guidelines from 15 of 21 regions using AGREE II found low methodological quality overall, with rigour of development and editorial independence scoring poorly.
-
Drone AEDs arrived first in two-thirds of arrests
A Chinese-led bibliometric and scoping review of 168 drone and eVTOL emergency medical services studies found drone-delivered AEDs arrived before ambulances in 67% of cases (median lead 3 min 14 s) and drone blood delivery cut transport time by 61%.
-
Facial recognition helped paramedics ID unknown patients
In a US double-blind randomised simulation study, 90 firefighter-paramedics using a cloud facial-recognition app identified a noncommunicative standardised patient far more often than controls (83.3% vs 21.4%, OR 13.87).
-
Fewer ultrasound frames preserved remote B-line detection
A US deep-learning evaluation of 1,844 lung ultrasound clips found 5-frame clips kept B-line sensitivity within 0.7 points of 32-frame clips (89.4% vs 90.1%) while cutting package size 84%, easing transmission over weak transport links.
