Insights

Children exposed to secondhand smoke (SHS) with asthma or bronchiolitis experienced more severe illnesses and required greater healthcare resources in the pediatric emergency department. This highlights the need for SHS assessment and cessation programs.

Area of Science:

  • Pediatric Emergency Medicine
  • Environmental Health
  • Respiratory Medicine

Background:

  • Secondhand smoke exposure (SHSe) in children is linked to severe respiratory illnesses and increased healthcare utilization.
  • Hospital data indicate a significant impact of SHSe on pediatric respiratory health outcomes.

Purpose of the Study:

  • To evaluate the association between SHSe and illness severity/resource utilization in children presenting to the pediatric emergency department (PED).
  • To analyze these associations for three common pediatric respiratory conditions: asthma, bronchiolitis, and pneumonia.

Main Methods:

  • A retrospective review of a yearlong sample of PED patients with documented SHSe status and diagnoses of asthma, bronchiolitis, or pneumonia.
  • Analysis included variables such as triage category, oxygen saturation, diagnostic tests, interventions, medications, and patient disposition.
  • Logistic and linear regression models were used to control for confounding factors like sociodemographics and medical history.

Main Results:

  • Approximately one-quarter of the 3,229 included children had documented SHSe.
  • Children with SHSe and asthma were more likely to receive corticosteroids and magnesium sulfate.
  • Children with SHSe and bronchiolitis showed increased likelihood of receiving racemic epinephrine, chest X-rays, and hospital admission.

Conclusions:

  • Secondhand smoke-exposed children with asthma or bronchiolitis exhibit greater illness severity and resource utilization.
  • Findings underscore the critical need for SHSe assessment, cessation interventions, and further research within the PED setting.

Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

Assessment of Respiration

The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
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...

Physical Assessment of the Respiratory Tract I: Health History

Physical assessment of the respiratory tract is critical to patient care. It allows healthcare professionals to identify and manage various respiratory conditions. The process involves a combination of subjective and objective data collection.
Subjective Data
Subjective data provides vital information about the patient's health history and symptoms. This data is typically collected through interviews in which patients describe their experiences, symptoms, and concerns.
