CIRCABREATH

Breathing, a sign of vitality.

A comprehensive breathing assessment: spirometry, plethysmography, nasal nitric oxide measurement and diffusing capacity (DLCO) to assess lung function and screen for respiratory conditions.

Who is it for?

The examinations

An assessment tailored to the clinical profile

The CIRCABREATH pathway begins with a specialist consultation, followed by respiratory examinations carried out according to your clinical needs.

First pulmonology consultation

Consultation · Specialist pulmonologist

An in-depth clinical assessment and referral to the most relevant examinations.

  • Analysis of respiratory symptoms (dyspnoea, cough, tightness, wheezing)
  • Assessment of medical and family history
  • Review of exposures (tobacco, environment, allergens)
  • Full respiratory clinical examination
  • Proposal of a personalised breathing assessment

Overnight oximetry: OtwoFellow

Home examination · Non-invasive

Analysis of overnight oximetry using the connected Oxyring. Assessment of the cardiovascular risk associated with apnoea.

  • Oxygen saturation (SpO₂) and heart rate
  • Pulse wave and Hypoxic Burden
  • PWAD: Pulse Wave Amplitude Drops (overnight vascular stress)

Pulmonary function tests (PFTs)

Gold-standard examination · Pulmonology

Essential tests for the diagnosis, severity assessment and follow-up of respiratory diseases.

  • Spirometry: FEV1, FVC, Tiffeneau ratio
  • Plethysmography: lung volumes and residual volume
  • CO diffusing capacity (DLCO): oxygen transfer into the blood
  • Measurement of airway resistance
  • Bronchodilator test: reversibility of obstruction

Exhaled nitric oxide measurement (FeNO)

Simple examination · Bronchial inflammation

A non-invasive marker of eosinophilic bronchial inflammation. A quick, painless examination.

  • Aids the diagnosis of asthma
  • Assessment of the level of airway inflammation
  • Monitoring the effectiveness of anti-inflammatory treatment
  • Adjustment of inhaled corticosteroid doses

Exercise challenge test

Cardio-respiratory examination · Exertion

Detects exercise-induced asthma, exercise hypoxaemia or unexplained dyspnoea.

  • Spirometry before and after exercise (FEV1, flow rates)
  • Oxygen saturation, heart rate and ECG
  • Continuous monitoring of reported symptoms

Objectives

  • Trigger and measure exercise-induced bronchoconstriction
  • Assess exercise tolerance
  • Adjust respiratory treatment

Allergy skin tests (Prick tests)

Allergy · Gold-standard diagnosis

Identification of allergic sensitisation to the main respiratory and food allergens.

  • Pollens, dust mites, animal dander, moulds
  • Food allergens based on the case history
  • Reading after 15–20 min: results in mm

Indications

  • Asthma and allergic rhinitis
  • Atopic eczema, urticaria
  • Assessment before allergen immunotherapy
