Objective:
This study tested a randomized controlled trial of RVA Breathes, a community asthma program, in reducing asthma-related healthcare utilization among children living in an area with a high poverty rate.
Methods:
Participants included 250 caregivers (78% African American/Black; 73.3% household income<$25,000/year) and their children with asthma (5-11 years). Inclusion criteria included an asthma-related emergency department (ED) visit, hospitalization, unscheduled doctor's visit, or systemic steroids in the past 2 years. Families were randomized to a full active intervention (asthma education with community health workers [CHWs], home remediation with home assessors, and a school nurse component; n = 118), partial active intervention (asthma education and home remediation; n = 69), or a control group (n = 63) for 9 months. Measures on healthcare utilization and asthma-related factors were collected. Follow-up assessments occurred across a 9-month period.
Results:
Although we did not find any significant effects, there was a trend toward significance for a group by time effect with objective healthcare utilization as the outcome (F4,365 = 2.28, p = .061). The full intervention group experienced a significant decrease from baseline to 9-month follow-up compared with the other groups (p < .001). Only the full intervention group experienced a significant increase in reported asthma action plans across time (no significant group effect).
Conclusions:
In the context of the unprecedented COVID-19 pandemic, which led to a substantial global decrease in healthcare utilization, the study's main hypotheses were not supported. Nevertheless, findings support the benefit of community asthma programs that integrate care across multiple settings and connect families with CHWs.

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:
Assessment of Respiration
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like...
Assessment of Ventilation I: Respiratory Rate
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.
Critical Guidelines for Assessing Ventilation:
Respiratory Volumes
Tidal Volume (TV) Tidal volume (TV) is the air inhaled or exhaled in a...
Respiratory Volumes and Capacities I
Respiratory Capacities
One key metric is the Inspiratory Capacity (IC), which represents the maximum amount of air that can be inhaled with full effort. IC is calculated by summing the tidal volume and inspiratory reserve volume, typically ranging from 2.4 to 3.6 liters.
The Functional Residual Capacity (FRC) represents the air in the...
