Overview

An Efficient, Automated Assessment Tool

Traditional respiratory mechanics maneuvers to assess lung health and determine readiness for weaning require disconnecting the ventilator circuit, potentially increasing the risk of circuit contamination.

The Puritan Bennett™ Respiratory Mechanics software offers an alternative to traditional maneuvers. Its maneuvers assess vital capacity, negative inspiratory force and respiratory drive (P0.1) without disconnecting the circuit or using outside equipment.

Clinicians can quickly assess patient respiratory therapy needs based on these measurements, while avoiding the probability of cross-contamination and risk of infection because there is no need to disconnect the breathing circuit during the automated measurements.

Product Features

Puritan Bennett™ Respiratory Mechanics software makes it easy to assess and rapidly make any necessary changes in a patient’s respiratory therapy. The software provides coached respiratory maneuvers such as negative inspiratory force (NIF) and vital capacity (VC). The Respiratory Mechanics software data, including occlusion pressure, can help clinicians determine if a patient is ready to be weaned.

Our Respiratory Mechanics software calculates and displays clinical indicators that may be useful in assessing the patient’s current respiratory status. The calculations displayed are listed below.

Dynamic compliance (CDYN) and resistance dynamics (RDYN)

  • Respiratory Mechanics software estimates the compliance and resistance of the patient’s lungs and chest wall. The measurement of CDYN and RDYN indicate the impedance characteristics of the lungs, chest wall and conducting airways. Changes in either of these values may reveal changes in the elastic properties of the lung and/or chest wall or in the ability of the conducting airways to accommodate a particular flow of gas. Dynamic compliance and dynamic resistance are calculated only for mandatory breaths.

Peak expiratory flow (PEF) rate

  • Peak expiratory flow is the maximum flow rate observed during exhalation, excluding the first 100 ms of data. PEF can be used as an indicator of obstructed airways.

End expiratory flow (EEF) rate

  • End expiratory flow is the rate of expiratory flow that occurs at the end of exhalation and can be used to determine whether expiratory time is adequate to prevent gas trapping and intrinsic PEEP. The end expiratory flow rate is calculated as the expiratory flow that occurs when flow integration terminates during exhalation or when a new breath is initiated.

Peak spontaneous flow (PSF) rate

  • Peak spontaneous flow is the maximum inspiratory flow rate sampled during a spontaneous inspiration. It is a good predictor of impending air hunger and helps the clinician set peak flow or choose an optimum level of pressure support.

Acute Care & Monitoring

Discover how we can support you in providing the best care for all your critical care & acute care patients.

 

Medtronic announced that it has decided to keep the Patient Monitoring and Respiratory Intervention businesses as a part of Medtronic, given changing market conditions. These businesses will get increased investment and be combined and called Acute Care & Monitoring (ACM).

Medtronic also made the decision to exit the ventilator product line.

Amid evolving market conditions and a shift to lower acuity ventilators, this decision aligns with Medtronic’s strategy to concentrate resources on our market-leading positions and accelerate innovation-driven growth.

While this decision will take time and planning, we are committed to supporting our existing ventilation customers. We will continue to provide service and support throughout the ventilator life cycle, along with meeting our service contract obligations.
