BackgroundPreterm infants often experience oxygen saturation (SpO2) instability due to immature respiratory control. While Kangaroo Mother Care (KMC) is known to improve cardiorespiratory stability, its impact on detailed SpO2 dynamics using histogram analysis has not been well studied.MethodsIn this prospective observational study, 120 paired sessions of KMC and off-KMC were analyzed in preterm infants (26 + 0 to 32 + 6 weeks gestation) admitted to a tertiary neonatal unit. Each session involved continuous SpO2 monitoring using Masimo Radical-7 oximeters. The primary outcome was the percentage of time with SpO2 ≤90%. Secondary outcomes included subgroup analyses by postmenstrual age (PMA) and respiratory support status.ResultsInfants spent less time with SpO2 ≤90% during KMC (median 10%, IQR: 7-17) compared to off-KMC (12%, IQR: 8-18), although not statistically significant (p = 0.06). A significant reduction was noted in infants on room air (median 9% vs 11%; p = 0.01). No significant difference was observed in those on CPAP, HFNC, or NIPPV. Infants with PMA >34 weeks showed an improvement in histogram trend during KMC, which was not statistically significant (p = 0.06).ConclusionsOverall, KMC showed a trend towards improved oxygen saturation patterns, although this was not statistically significant. Among stable preterm infants on room air without respiratory support, KMC was associated with a significant improvement.

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:
