Overview

Patient Spirometry measures airway pressures, flow, volumes, compliance and airway resistance breath-by-breath at the patient’s airway. The dynamic interrelationships of pressure and volume or flow and volume are displayed as graphical loops.

In addition the inspired and expired gas concentrations are measured (CO2, O2 and anesthetic agents).


All parameters are measured through a single, lightweight flow sensor and gas sampler, placed at the patient’s airway. The “close to the patient” measurement is sensitive and continuous reflector of patient’s ventilatory status, obtained independently of the ventilator used.


Benefits

Patient Spirometry is an excellent tool for managing the patient’s ventilation during anesthesia and critical care:

Measurement at the airway

  • Represents real patient values
  • Is not influenced by ventilator hoses or other breathing system components

Saved reference loops

  • Enable fast visual detection of changes
  • Help in adjusting optimal ventilator settings
  • Help in comparison of actual and previous ventilatory status

Modular flexibility

  • Can be used with a variety of ventilators
  • Enables flexible change of modules between patients

Integrated information

  • Ventilatory and hemodynamic information on a single screen provides a complete picture of the patient status

Comprehensive documentation

  • Graphical and numerical trends to evaluate of patient’s history
  • Printed loops, trends and snapshots for easy reporting


Measurements

Patient Spirometry measurements are obtained through D-lite or Pedi-lite low sensors. Ventilator independent, the flow sensor obtains patient values proximally at the patient airway.

Single adapter for monitoring of patient airway gases, Patient Spirometry (lung mechanics) and Gas Exchange/Metabolics. Lightweight sensors can be used anywhere GE Healthcare respiratory monitoring technology is applied, including in anesthesia delivery and ICU ventilation.

For humid conditions, the D-lite+ and Pedi-lite+ flow sensors’ hydrophilic surface prevents the condensed water from disturbing the measurement.

Selection of the flow sensor is based on the tidal volume of the patient:

  • D-lite(+): 150 – 2000 ml
  • Pedi-lite(+): 5 – 300 ml 1

Cleaning: the disposable D-lite, D-lite+ and Pedi-lite+ sensors are for single patient use only. The reusable D-lite and Pedi-lite sensors can be:

  • hand washed
  • machine washed
  • disinfected with suitable disinfectants
  • steam autoclaved (max. temp. 132º C /270º F)

Positioning: Place all ports upwards to avoid condensed water from entering the tubings.

Patient Spirometry Accessories

Pre-connected kits meet all application areas and are designed to help make set-up quicker and easier.

Specific kits designed for humid conditions.

Selection between D-lite(+) and Pedi-lite+ sensor is based on the tidal volume of the patient.

Patient Spirometry kits are for single patient use only (depending on country regulations, limited reuse is tolerated if protected with a filter). Each kit contains:

  • Gas sampling line
  • D-lite, D-lite+ or Pedi-lite+
  • Spirometry tube
