Brief summary

A randomized crossover simulation trial of 123 emergency clinicians found that real-time device feedback dramatically improved pediatric bag-valve-mask ventilation quality, increasing guideline-adherent tidal volumes from 16.2% to 87.0%.

What NurseJet pulled from the source

Manual bag-mask ventilation is a critical, lifesaving intervention for children suffering acute respiratory arrest, but delivery of appropriate pediatric tidal volumes without barotrauma or gastric insufflation remains challenging. In a single-anonymized, randomized crossover trial across five emergency medical services agencies in three US metropolitan areas, 123 emergency clinicians ventilated a high-fidelity manikin simulating a 3-year-old child in respiratory arrest. Participants completed two sequential 2-minute ventilation trials—one with real-time visual feedback using the EOLifeX ventilation feedback device (VFD) and one without feedback—separated by a 10-minute washout period. Real-time feedback increased adherence to age-recommended tidal volumes from 16.2% to 87.0%. Ventilation rate adherence improved from 65.0% to 88.6%, and minimal mask leak (<30%) was maintained in 88.4% of breaths with feedback compared to 80.0% without feedback.

Why this matters for nurses

Pediatric emergency nurses and rapid response teams frequently provide manual ventilation during arrests and severe respiratory compromise. Because children have high chest wall compliance and low functional residual capacity, unguided manual bagging frequently leads to severe hyperventilation or dangerous overdistention. Objective feedback devices provide immediate visual cues that safeguard against excessive tidal volumes and erratic rates.

Bedside takeaway

In a randomized crossover study of 123 emergency clinicians ventilating a 3-year-old child manikin, real-time feedback increased guideline-adherent tidal volume delivery from 16.2% to 87.0% and rate adherence from 65.0% to 88.6%.

Key takeaways

Randomized crossover simulation study evaluated 123 emergency clinicians ventilating a simulated 3-year-old toddler.
Unassisted baseline ventilation rarely met pediatric standards, with only 16.2% of breaths delivering guideline-recommended tidal volumes.
Real-time visual feedback increased guideline-compliant tidal volume delivery to 87.0% and rate adherence from 65.0% to 88.6%.
Mask seal with less than 30% leak improved from 80.0% to 88.4% when feedback was active.

Practice implications

When delivering bag-mask ventilation to pediatric patients, use two-person technique when possible to optimize mask seal, utilize volume-limiting and feedback-guided adjuncts per unit protocol, and maintain deliberate, age-appropriate ventilation rates.

Limitations & cautions

Simulation manikin model evaluating simulated respiratory arrest rather than live clinical patient outcomes; short 2-minute testing intervals may not reflect clinician physical fatigue during prolonged resuscitations.

A multicenter randomized controlled trial of 87 critically ill adults found no significant differences in 24-hour weaning success (94% vs 81% vs 77%) or duration between flow-reduction-first, FiO2-reduction-first, or simultaneous HFNC weaning.

High-flow nasal cannula (HFNC) is standard supportive therapy for acute hypoxemic respiratory failure, yet clinical teams lack consensus on the optimal stepwise de-escalation sequence. The multicenter, randomized controlled SLOWH trial enrolled 102 adults across three tertiary care intensive care units who achieved clinical stability on HFNC and met standardized weaning criteria (PaO2/FiO2 >= 150 or SpO2 >= 92% on FiO2 <= 0.40 and flow <= 30 L/min). Following exclusions, 87 patients were randomized to flow reduction first (FR, n=31), FiO2 reduction first (OR, n=26), or simultaneous reduction (SR, n=30). The primary outcome was successful transition to conventional oxygen therapy without HFNC resumption, noninvasive ventilation, or endotracheal intubation within 24 hours. Weaning success was achieved in 94% of the FR group, 81% of the OR group, and 77% of the SR group (p = 0.15). Median weaning duration was also comparable: 31.0 hours for FR, 29.5 hours for OR, and 29.5 hours for SR (p = 0.87).

Key takeaways

Multicenter RCT of 87 adults across 3 tertiary ICUs compared flow-first (n=31), oxygen-first (n=26), and simultaneous (n=30) HFNC de-escalation.
Weaning success rates at 24 hours did not significantly differ between strategies: 94% flow-first, 81% oxygen-first, and 77% simultaneous (p = 0.15).
Median weaning duration was approximately 30 hours across all three arms (31.0 hr vs 29.5 hr vs 29.5 hr, p = 0.87).
Findings indicate bedside clinicians can individualize HFNC weaning order based on patient comfort and work of breathing without compromising weaning success.

Why this matters on shift

ICU and step-down nurses frequently manage HFNC titration and weaning trials at the bedside. Evidence demonstrating clinical equivalence across sequential flow reduction, FiO2 reduction, and simultaneous titration allows nurses and respiratory therapists to tailor the weaning trajectory to individual patient physiology—such as prioritizing flow reduction for airway comfort or FiO2 reduction to limit oxygen toxicity.

Bedside takeaway

In an 87-patient multicenter RCT of critically ill adults, flow-first (94%), FiO2-first (81%), and simultaneous (77%) HFNC weaning showed comparable 24-hour success rates (p=0.15) and similar median weaning durations (~30 hours).

Nursing implications

Assess work of breathing, accessory muscle use, and oxygenation saturation during HFNC de-escalation; whether titrating flow or FiO2 first, titrate gradually per provider orders and monitor closely for respiratory fatigue within the initial 24 hours of step-down.

Limitations & cautions

Relatively modest sample size (87 completed participants) may have been underpowered to detect small differences between weaning arms; conducted in tertiary academic centers with dedicated protocols.

A Bayesian secondary analysis of the 6,082-patient PARAMEDIC-3 trial calculated an 81.6% posterior probability that an intraosseous-first access strategy was inferior to intravenous-first access for 30-day survival in out-of-hospital cardiac arrest.

Securing rapid vascular access for resuscitation drug delivery is critical in cardiac arrest, but the relative clinical efficacy of intraosseous (IO) versus intravenous (IV) cannulation remains debated. Investigators conducted a pre-planned Bayesian secondary analysis of the multicenter PARAMEDIC-3 randomized trial (ISRCTN14223494), in which 6,082 adults experiencing non-traumatic out-of-hospital cardiac arrest were randomized to an initial IO-first or IV-first vascular access strategy. Using non-informative priors adjusted for baseline covariates, the posterior probability that IO-first access improved 30-day survival (odds ratio [OR] > 1.0) was only 18.4%, corresponding to an 81.6% probability that IO-first access was inferior (OR < 1.0). The probability of a small disadvantage (OR < 0.9) was 55.0%, and moderate disadvantage (OR < 0.75) was 13.4%. Similar patterns emerged for favorable neurological outcome, while for return of spontaneous circulation (ROSC) at hospital handover, the probability of IO inferiority was 98.0%.

Key takeaways

Pre-planned Bayesian secondary analysis of the PARAMEDIC-3 trial evaluated 6,082 adult out-of-hospital cardiac arrest patients.
Posterior probability that an IO-first approach improved 30-day survival was only 18.4%, with an 81.6% probability of inferiority compared with IV-first.
The probability that IO-first was inferior for return of spontaneous circulation (ROSC) at hospital handover was 98.0%.
Findings indicate that while intraosseous access is vital when IV access cannot be obtained, initial intravenous access remains clinically preferred for drug efficacy.

Why this matters on shift

Emergency and trauma nurses frequently manage vascular access during cardiac arrests in the emergency department and resuscitation bays. While IO devices provide rapid and reliable placement during difficult access, these Bayesian findings reinforce that intravenous administration delivers superior pharmacokinetics and resuscitation outcomes, supporting intravenous attempts as primary whenever readily achievable.

Bedside takeaway

In a Bayesian analysis of the 6,082-patient PARAMEDIC-3 trial, initial intraosseous access had an 81.6% posterior probability of inferior 30-day survival and 98.0% probability of inferior ROSC compared with initial intravenous access in cardiac arrest.

Nursing implications

Prioritize rapid intravenous cannulation attempts for resuscitation pharmacotherapy during cardiac arrest per ACLS protocols; deploy intraosseous access without delay when peripheral IV attempts fail or are clinically unfeasible.

Limitations & cautions

Secondary analysis of trial data subject to protocolized prehospital paramedic workflows; primary analysis modeled non-informative priors; exact drug delivery transit times were not directly measured.

Trauma, violence & abuse (PubMed)Oct 17, 2026Systematic Review

A systematic review and meta-analysis of 20 emergency department studies encompassing 7,498 women found intimate partner violence was associated with a three-fold increased risk of suicide attempt, with psychological violence showing a stronger association than physical violence.

Systematic ReviewResearchWorkflowQuality ImprovementAI summary · original source linked below

Women experiencing intimate partner violence (IPV) and acute suicidality frequently seek medical evaluation in emergency departments (EDs), but the intersection between these two acute presentations is often overlooked during fast-paced triage. This systematic review, meta-analysis, and narrative synthesis synthesized 20 ED-based studies comprising 7,498 women across three global databases. Investigators used random-effects models and evaluated study quality with the Joanna Briggs Institute (JBI) checklist. Overall, 22% (95% CI: 11%–36%) of women presenting to the ED for suicide-related care had a history of physical IPV, while 13% (95% CI: 8%–18%) of women with known IPV histories reported active suicidality. A history of IPV was associated with a three-fold increase in the risk of suicide attempt (risk ratio [RR] 3.00; 95% CI: 1.39–6.47). Notably, psychological IPV demonstrated a stronger association with suicide risk (RR 3.23; 95% CI: 1.68–6.19) than physical IPV alone (RR 2.00; 95% CI: 1.26–3.17).

Key takeaways

Systematic review synthesized 20 emergency department studies encompassing 7,498 women.
Nearly 1 in 4 women (22%; 95% CI: 11%–36%) presenting to the ED with suicidality had experienced physical IPV.
IPV was associated with a three-fold higher risk of suicide attempt (RR 3.00; 95% CI: 1.39–6.47).
Psychological IPV showed a higher risk ratio for suicide attempts (RR 3.23; 95% CI: 1.68–6.19) than physical IPV (RR 2.00; 95% CI: 1.26–3.17).

Why this matters on shift

Emergency nurses are the primary healthcare professionals conducting universal triage, suicide risk screening (e.g., C-SSRS), and domestic violence assessments. Recognizing that nearly one-quarter of suicidal female presentations co-occur with IPV—and that non-physical, psychological abuse carries an even higher relative risk for suicide attempt—demands that ED nursing assessments integrate trauma-informed safety planning rather than treating suicidality and relationship violence in isolation.

Bedside takeaway

In an ED meta-analysis of 7,498 women, intimate partner violence tripled suicide attempt risk (RR 3.00), with psychological IPV (RR 3.23) linked more strongly than physical IPV (RR 2.00).

Nursing implications

Conduct routine IPV and suicide screenings privately away from companions or visitors, assess for emotional and psychological coercion even when physical injury is absent, and connect patients showing combined risk immediately to hospital social work, victim advocacy, and safe crisis intervention pathways.

Limitations & cautions

High between-study heterogeneity across meta-analytic models (I² > 75%); high risk of bias identified in half of the included primary studies; relied largely on cross-sectional self-reported survey measures.
