Healthcare professionals using a self-inflating bag (SIB) for neonatal positive pressure ventilation (PPV) experienced more muscle fatigue and shoulder strain. The T-piece device is recommended for better ergonomic outcomes in critical care settings.
Area of Science:
- Medical Ergonomics
- Neonatal Resuscitation
- Occupational Health
Background:
- Healthcare professionals (HCPs) face ergonomic challenges in critical situations, leading to fatigue and musculoskeletal injury.
- Neonatal positive pressure ventilation (PPV) is crucial for newborns needing resuscitation, with device choice potentially impacting HCPs' physical well-being.
Purpose of the Study:
- To evaluate the impact of different neonatal positive pressure ventilation (PPV) devices and mask-hold techniques on healthcare professional fatigue and musculoskeletal injury risk.
- To compare the ergonomic outcomes between T-piece ventilators and self-inflating bags (SIBs) during neonatal resuscitation.
Main Methods:
- Assessed forearm extensor muscle fatigue and shoulder musculoskeletal injury risk.
- Measured mean shoulder elevation angles during PPV device use.
- Compared outcomes between T-piece and SIB devices, considering various mask-hold strategies.
Main Results:
- Self-inflating bags (SIBs) led to significantly higher forearm extensor muscle fatigue (47.61%) compared to T-pieces (14.29%).
- SIBs resulted in increased shoulder musculoskeletal injury risk, indicated by higher mean shoulder elevation angles (45.58°) versus T-pieces (27.29°).
Conclusions:
- The choice of PPV device significantly affects HCP ergonomics during neonatal resuscitation.
- T-piece ventilators offer superior ergonomic outcomes, reducing fatigue and injury risk compared to SIBs.
- When clinically feasible, T-piece devices should be prioritized to enhance HCP well-being in critical care.

A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.

01:29Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
