Investigation into Deep Breathing through Measurement of Ventilatory Parameters and Observation of Breathing Patterns
Published on: September 16, 2019
Abstract:
The inability to breathe freely and clearly is a major source of concern to patients and a common symptom in many sinonasal conditions (1). There are of course some semantic differences between terms such as ‘obstruction’, congestion’ and ‘blockage’, which have to be clarified when taking a clinical history as the presence of inflammation may produce the sensation of congestion without actually being associated with mechanical obstruction to airflow (2). Notwthstanding this, nasal obstruction is the commonest complaint in chronic rhinosinusitis with and without nasal polyps (3) and is a major feature of conditions from the common cold and acute bacterial rhinosinusitis to allergic and non-allergic rhinitis, septal deformity or a tumour. Paradoxically, many people, myself included, go through life largely oblivious to a significant septal deflection. It therefore begs the question as to why an individual with a long-standing anatomical variant such as this, suddenly presents with the symptom of nasal blockage and it is important that we do not simply focus on the septum (or turbinate) but rather ask ourselves ‘Why now?’ instead of simply listing the patient for septal surgery.

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 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.
