A novel method for non-invasive respiration monitoring
Abstract:
In this paper we present an atypical method for measuring respiration volume. We infer heart rate variability (HRV) from an electrocardiogram (ECG) and present results from a pilot study of 6 participants to validate measuring respiration volume from HRV in comparison to the Cosmed K4b(2). We show a qualitative correlation and trend between the known respiration volume as measured by the Cosmed K4b(2) and the new method for measuring lung volume. From these results, we propose guidelines for an in-depth study of measuring respiration volumes from heart rate variability.

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.

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 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:
