Hayek SCS

The Hayek SCS is an easy-to-use airway clearance device that can be utilized in both pediatric and adult patients.

Unlike other Chest Percussion Devices, The Hayek SCS does not require special positioning and breathing techniques. The Hayek SCS can be used in the home-care setting as well as the Hospital. Treatment can be administered either by clinical or non-clinical personnel. The Hayek SCS is a user-friendly, fully computerized device, which has eleven sizes of cuirass enabling treatment of both adult and pediatric patients. Compact and lightweight, the Hayek SCS is ideally suited to provide Secretion Clearance. The Hayek SCS should be used when there is atelectasis, excess secretions or CO2 retention.

The main modality for The Hayek SCS is called Secretion Clearance.

Modes of Operation


The Secretion Clearance Mode consists of 2 main portions/therapies:

  • The first mode is called Vibration Mode
  • The second mode is called the Cough Assist Mode

The Vibration Mode generates a true High Frequency Chest Wall Oscillation (HFCWO) via the cuirass shell.

  • Using frequencies of 240-1200 Cycles Per Minute, positive and negative pressures are applied to effectively expand and truly oscillate the chest wall and lungs to facilitate mobilization of secretions via the Vibration Mode.
  • This mode shakes and thins secretions.
  • Example settings:
    • Insp/Expiratory: -8 +8
    • Frequency: 800cpm
    • Time 3-4minutes
    • Decrease the frequency for more tenacious secretions.
    • Expiratory pressures in vibration mode are defaulted to the same as inspiratory pressures.

Higher pressures are tolerated well e.g. +/- 15

The Cough Assist Mode mimics a huff cough to force up secretions. Using an inverse I:E Ratio with an extended inspiration and sharp expiration. The Hayek SCS facilitates mobilization and removal of pulmonary secretions.

  • Example Settings:
    • Inspiratory: -25
    • Expiratory: +15
    • I:E Ratio: 4:1
    • Frequency: 50
    • Time: 3minutes
    • The negative pressure can be made more negative as required.
    • Unlike any other device, mucus can be removed by the Cough Assist Mode with the use of any other device, such as a Coughalator, etc.

Completion of both modes represents one cycle of secretion clearance mode. Each secretion clearance session should last between 30-60 minutes. It is possible to use higher pressures in cough mode e.g. -35 +25 as tolerated by the patient. It is helpful to introduce one or two cycles every few hours for most infants with bronchiolitis. The number and frequency of cycles can be adjusted according to the severity of the infant’s condition. Occasionally some infants cannot tolerate a full 3 minutes of cough when it is first introduced, in which case the mode setting can be changed earlier. They usually do get used to it fairly quickly.
 




The Clear Advantage



SCS

  • Direct comparison of The Hayek SCS and other HFCWO devices.
  • All “Vest” type devices utilize a high frequency of chest wall compression (HFCWC) by using only positive pressure.
  • Oscillation requires both a negative and positive pressure applied to the chest wall, which on Biphasic Cuirass Ventilation (BCV) can offer.
  • The Hayek SCS offers a true HFCWO.
  • Unlike any other “Vest” device, the Hayek SCS utilizes BCV’s unique oscillatory wave applied to the lung through the cuirass shell and chest wall provides a powerful secretion thinning effect, as well as a significant increase in the transport of the patient’s retained secretions for expectoration.
  • After each cycle of oscillation, The Hayek SCS provides cough assistance automatically using the same non-invasive cuirass shell.
  • A full inspiration, followed by a strong expiratory gas flow ensures that every patient, regardless of muscle strength, can generate a productive cough effort to expel secretions.



Patient Groups



The Hayek SCS is used for airway clearance associated with many possible diagnoses.
