Insights

Impulse oscillometry (IOS) is a useful tool for assessing pediatric lung function, particularly in asthma. While easy to perform, interpreting IOS results in children requires careful consideration.

Area of Science:

  • Pediatric Pulmonology
  • Respiratory Physiology

Background:

  • Lung function assessment in children with respiratory diseases is crucial for diagnosis and management.
  • Spirometry is a standard but can be challenging in young children.
  • Impulse oscillometry offers an alternative, non-invasive method for evaluating airway mechanics.

Purpose of the Study:

  • To review the literature on the use of impulse oscillometry for assessing lung function in pediatric respiratory diseases.
  • To specifically evaluate its application in children with asthma.

Main Methods:

  • Systematic literature search of Medline, PubMed, and Lilacs databases.
  • Keywords included forced oscillation, impulse oscillometry, and asthma.
  • Focused on studies assessing lung function in children.

Main Results:

  • Impulse oscillometry (IOS) measures airway resistance and reactance, correlating well with spirometry.
  • IOS is sensitive for assessing bronchodilator response and therapeutic effects in pediatric asthma.
  • It aids in evaluating disease control but interpretation can be challenging in certain cases, like children with attention deficit.

Conclusions:

  • Impulse oscillometry is a valuable tool for pediatric lung function measurement.
  • The test is relatively easy to perform in children.
  • Clinical interpretation of IOS results requires expertise and consideration of limitations.

Assessment of Ventilation I: Respiratory Rate

Assessment of Ventilation
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:
Special considerations while measuring oxygen saturation01:19

Special considerations while measuring oxygen saturation

Assessing respiratory rate concurrently with pulse measurement is fundamental to patient care, providing valuable insights into the patient's respiratory function. The normal breathing rate for an adult usually falls within a normal range of 12 to 20 breaths per minute. Abnormal respiratory rates can signal underlying health conditions or the need for immediate intervention.
Ensuring accuracy in vital sign recordings while prioritizing patient comfort and minimizing anxiety is important. 
Assessment of Respiration01:23

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 asthma or COPD,...
Assessment of Ventilation II: Respiratory Depth and Rhythm01:29

Assessment of Ventilation II: Respiratory Depth and Rhythm

Respiratory Depth
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:
Pulmonary Function Tests01:25

Pulmonary Function Tests

Pulmonary Function Tests (PFTs)
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
PFTs involve using a spirometer, a...
Pulse Oximetry01:24

Pulse Oximetry

Pulse oximetry, or SpO2, is a non-invasive method for continuously monitoring arterial oxygen saturation (SaO2). This procedure involves attaching a probe or sensor to the patient's fingertip, forehead, earlobe, or nose bridge. The sensor works by detecting changes in oxygen saturation levels through light signals generated by the oximeter and reflected by the pulsing blood under the probe.
Purpose
Average SpO2 values are greater than 95%. If the readings fall below 90%, it indicates that...
