Tidal flow/volume (TFV) measurements offer a valuable method for assessing lung function in patients unable to perform forced maneuvers. These measurements provide crucial insights into respiratory diseases, especially in children and those with chest conditions.

Area of Science:

  • Pulmonary Medicine
  • Respiratory Physiology
  • Pediatric Pulmonology

Background:

  • Lung function assessment is challenging in young children and patients with chest diseases who cannot perform forced maneuvers.
  • Tidal breathing analysis offers a non-invasive alternative for evaluating respiratory function across various age groups and conditions.
  • Existing tidal flow/volume (TFV) parameters, like tPTEF/tE, are widely used, but new parameters focusing on curve shape are emerging.

Purpose of the Study:

  • To discuss practical considerations and applications of tidal flow/volume (TFV) measurements in respiratory diagnostics.
  • To highlight the utility of TFV measurements in research and clinical settings for patients unable to perform conventional lung function tests.
  • To explore the potential of TFV parameters in identifying respiratory issues and predicting risks.

Main Methods:

  • Analysis of tidal breathing using flow/volume (TFV) loops and flow/time traces.
  • Calculation of established parameters such as the ratio of time or volume to peak expiratory flow (tPTEF/tE or VPTEF/VE).
  • Discussion of emerging parameters focusing on the latter portion of the TFV curve.

Main Results:

  • Reduced tPTEF/tE is observed in infants born to smoking mothers, indicating a risk factor for recurrent wheeze.
  • Acute bronchial obstruction (BO), including bronchiolitis and asthma, is associated with significantly reduced tPTEF/tE.
  • TFV measurements demonstrate responsiveness to challenges (histamine, methacholine) and bronchodilators in various populations.

Conclusions:

  • Tidal flow/volume (TFV) measurements are valuable supplementary tools for investigating respiratory diseases.
  • TFV measurements are particularly useful in subjects who cannot cooperate with conventional lung function tests due to age or condition.
  • Standardization of TFV measurement techniques and reporting is necessary for wider clinical adoption and research comparability.
