Hayek HRTX

The Hayek HRTX

The Hayek HRTX Ventilator provides an efficient and effective method of non-invasive external ventilation and can be a real alternative to traditional forms of ventilation, including non-compliant Bilevel Positive Airway Pressure users. It actively controls the inspiratory and expiratory phases of respiration (using BCV), making the device work physiologically and successfully, while increasing the patient’s cardiac output.

Using the various trigger modes, the Hayek HRTX Ventilator may be synchronized to the patient’s own respiratory or cardiac cycles. During treatment while using the Hayek HRTX, a negative pressure is generated within the chest cuirass, for inspiration or continuous inspiratory assistance, and applies a positive pressure within the cuirass inducing expiration. This positive expiratory pressure means that expiration is an active phase in the respiratory cycle this makes the Hayek HRTX particularly efficient at CO2 clearance. The pressure applied within the cuirass acts uniformly over the thorax. Subsequently, lung expansion is also uniform ventilating all areas of the lungs. In positive pressure ventilation (PPV) the gas pushed into the lungs naturally follows the path of least resistance therefore ventilating the already well ventilated areas.

Increase in pressures/volumes to aid ventilation of all areas of the lungs leads to barotrauma, volutrauma and possible development of a pnuemothorax. These complications, along with those of ventilator associated pneumonia, are of no relevance with BCV.

Modes of Operation

Continuous Negative Pressure (CNEP)

This mode of support uses CNEP which is applied to the thorax to expand lungs evenly for ventilation. This mode can be easily adjusted/manipulated to suit the individual patient’s requirements. The level is then adjusted until the work of breathing decreases. This will be noted with decreased retractions, use of expiratory muscles, metabolic acidosis, stable or falling CO2 and improved oxygenation.

Indications for CNEP Use:

Control (Mandatory Controlled Ventilation)

In control mode, positive and negative pressures are applied, along with a controlled I:E ratio, to actively control inhalation and exhalation. This allows for the provision of full ventilator support. A mandatory respiratory rate is set and delivered. The patients synchronize with the mandatory breaths, as BCV utilizes the patient’s own thorax to effect respiration. This is a unique function that only BCV has; The Control Mode mimics physiological respiration.

Indications for Control Mode:

There are 2 modes triggered by the patient’ s respiratory effort. These modes can be used as pressure support modes and an aid to weaning.

Respiratory Triggered

Respiratory Synchronized

Secretion Clearance

To finish the secretion clearance phase, a cough assist mode mimics a huff cough to force up secretions. Using an I:E Ratio with an extended inspiration and sharp expiration (inverse I:E ratio), BCV facilitates mobilization and removal of pulmonary secretions.
