Abstract:
The goal of the development phase of the CPR Instructor Real-time Review through Use of Simulation (CIRRUS) research program was to create a video library portraying a spectrum of objectively verified simulation chest compression performances. Investigators scripted and recorded 12 two-person cardiopulmonary resuscitation (CPR) videos with specific chest compression parameters encompassing a range of hand positions, rates, depths, and chest releases in combinations that proportionately reflected typical learner cohort performances. Six videos were designated to portray adequate chest compressions, whereas the other six videos were to feature inadequate compressions. All 12 final 2-minute videos showed chest compression parameters as originally specified within tolerances to comply with American Heart Association recommendations. Deviations from specification were 1 to 10 cpm (mode = 4 cpm) for compression rate and -1.4 to 1.3 cm (mode = 0.9 cm) for depth. The program's collection of simulated CPR videos with objectively verified chest compression performances may help researchers and educators study and improve CPR instruction and provider preparation for the effective delivery of optimal patient care.

Assessment 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:
