Mechanical ventilation during military activities and on the battlefield can be essential at the time of emergent situations.

With Biphasic Cuirass Ventilation (BCV), advances in the application of greater mechanical ventilation can now be achieved. BCV will aid the military with mechanical ventilation on the battlefield. BCV can be used during surgery, treatment of acute respiratory distress syndrome (ARDS), mechanical ventilation during flight, and many more applications, to name a few.

Biphasic Cuirass ventilation with the Hayek MRTX delivers mechanical ventilation non-invasively to all levels of military and battlefield medical care. BCV will dramatically improve the survival of wounded military personnel in a safe, effective, and non-invasive way.

Currently, Endotracheal (ET) intubation is utilized in conjunction with positive pressure ventilation for respiratory support in patients with cardiac or respiratory arrest during emergent situations.

Unfortunately, laryngoscopy and endotracheal intubation require a skilled provider who performs this procedure on a frequent basis. Medical military personnel and medics receive training in the use of the endotracheal tube, but they use it infrequently.
Airway obstruction leads to death in minutes if left untreated. If the combat scenario allows, airway control on the battlefield may be necessary in the severely wounded patient suffering from hemorrhage or in a comatose state, in the patient likely to have respiratory failure after inhalational, burn, chemical, or blast injury, and in the patient with direct airway trauma.

BCV with the Hayek MRTX can completely ventilate these patients requiring emergency airway management before reaching a field hospital, in a safe, effective and non-invasive way.

In providing military field care, the care provider is under reduced levels of hostile fire and has more time to provide medical therapy. In this situation, attention is directed toward airway and breathing.
Unconscious patients with airway obstruction may require more definitive airway management.

Use of the standard laryngoscope involves white light, which may alter night vision. Although red light may be used, this could also give away the patrol’s position. Maxillofacial injuries may make endotracheal intubation very difficult or impossible even for paramedics with considerable airway experience under the most ideal circumstances. Many military medics have limited experience with laryngoscopy and endotracheal intubation on live patients. Laryngoscopy requires considerable skill and frequent performance to maintain that skill.

The Hayek MRTX allows for easy learning, rapid application, and minimal deterioration in skill. The Hayek MRTX can significantly improve military medical personnel’s ability to care for the combat casualty under any situation.

Extraction of the military personnel during war may take place by naval craft, land vehicles, or helicopter. The Hayek MRTX is completely portable. Ventilation to the patient can be provided seamlessly during transport with the Hayek MRTX. Care can than continue from the field hospital to the hospital with the Hayek MRTX.

Biphasic Cuirass Ventilation (BCV) provides the innovation that military health officials are looking for and is a real solution to the many problems encountered with traditional forms of ventilation.

A ventilator such as the Hayek MRTX delivers a comprehensive and effective solution for military personnel by providing complete and non-invasive ventilation.

The MRTX utilizing Biphasic Cuirass Ventilation, or BCV, can be applied very easily and with an incredibly short learning time for the end user. Clinical studies have shown that the application of BCV with the Hayek MRTX can be taught in as little as 5 minutes, or simply by watching a short instructional video by virtually anyone.

Most importantly, in the unlikely event of misapplication of the Hayek MRTX, Biphasic Cuirass Ventilation carries absolutely no risk to the patient, unlike positive pressure ventilation, which may prove fatal.

The innovative MRTX leverages advanced technology, while designed in a way that doctors, nurses, health professionals and even non-clinical personnel can operate quickly without any special training. This makes it ideal for personnel providing rapid treatment at the scene of an emergency, while avoiding the difficulties and complication that will likely arise with invasive ventilation.

Biphasic Cuirass Ventilators, such as the Hayek MRTX are easily portable, are extremely lightweight, with a ruggedized case for outdoor use. The rechargeable battery of the Hayek MRTX provides full ventilation for up to 6 hours and can also run on 12 and 24 volts, as well as on mains power allowing the Hayek MRTX to be used for routine care as well. Preset ventilation parameters based on patient dimensions, eliminate any setting concerns.

With BCV, the goal of increasing the number of individuals trained or cross-trained to manage ventilator-dependent patients is easily achieved with the Hayek MRTX. The Hayek MRTX does not require skilled medical personnel.

Why the Hayek MRTX?

The cuirass is applied to the patient’s chest. Its disposable seal allows for a comfortable, but airtight fit. The flexible transparent plastic cuirass is available in 12 sizes, chosen according to patient weight and body size, fitting anyone from neonates to adults.

The attached power unit actively controls both the inspiratory and expiratory phases of the respiratory cycle. Biphasic Cuirass Ventilation works physiologically. It operates externally by creating negative chamber pressure on the entire chest area. This causes the lungs to expand, and for inhalation to occur. Using positive pressure in the cuirass, it then creates an expiratory phase, exhalation.

BCV is easy to apply using the Hayek MRTX, even when cumbersome protective gear is worn; making it possible for one person to treat several patients. This is especially important where large numbers of people require emergency treatment.

The patented technology used in the Hayek MRTX greatly increases minute ventilation and enabling effective ventilation in both normal and injured lungs. Additional benefits of BCV include the facilitation of secretion clearance and improvement in cardiac output during ventilation.

The Hayek MRTX is portable and can operate outside medical centers with no need for additional equipment. Once attached to an injured patient, it may accompany them until he or she reaches the hospital and obtains medical treatment with no need for additional intervention on route. Ventilation may thus be initiated effectively on the battlefield, continue on the way to the hospital, and save lives during those crucial moments by providing treatment before the patients condition deteriorates.

The Hayek MRTX utilizing BCV is the only viable solution for providing ventilation in emergency military situations.

The Hayek MRTX was designed to be manufactured very quickly in the event of a surge in the number of patients requiring ventilation.


Biphasic Cuirass Ventilation | Eliminate the Harmful Side Effects

With the appropriate cuirass shell, BCV can be used on anyone.

Positive pressure ventilation techniques, as well as invasive mechanical ventilation, have a lengthy list of adverse effects, which BCV does not. Some potential adverse physiologic effects of positive pressure ventilation (PPV) are:

  1. Decreased cardiac output
  2. Unintended respiratory alkalosis
  3. Increased intracranial pressure
  4. Gastric distension
  5. Impairment of hepatic and renal function

Perhaps the most feared complications occurring during mechanical ventilation include:

  1. Pneumothorax
  2. Bronchopleural fistula
  3. Development of nosocomial pneumonia

The use of positive pressure ventilation can lead to barotrauma, volutrama and possible development of a pneumothorax. These complications can be entirely avoided with the use of BCV.

BCV offers effective, even and natural ventilation without risk to the patient and can be applied by virtually anyone with minimal training.

BCV will also facilitate the clearance of secretions in contrasts to PPV, which compounds secretions.

BCV provides the only real solution to the complexities encountered in delivering life saving ventilation in emergency military situations.

BCV – Here’s the Proof

Exhibit A

Application of a Cuirass and initiation of Biphasic Cuirass Ventilation by gear-protected physicians was investigated. In the study, 10 physicians of multiple specialties applied a cuirass shell on an adult patient. Biphasic Cuirass Ventilation was initiated using the Hayek RTX ventilator. ET intubation and manual ventilation of a mannequin were also reasonably evaluated.
In conclusion, physicians wearing full protective gear applied a cuirass shell and instituted Biphasic Cuirass Ventilation much quicker than ET intubation and manual positive pressure ventilation.

Exhibit B

In another study Comparing the MRTX ventilator to positive pressure ventilation (PPV) in OP (paraoxon) poisoned pigs, three study groups were examined:

  • Control – no ventilatory support
  • PPV – using an airbag ventilation (more abundant measure; technical difficulty)
  • Biphasic ventilation Using the MRTX

There were a total of 23 animals – two were used as controls to establish the specific respiratory insult model, seven in every other group. Each animal was exposed to 1.2LD50 of paraoxon IM Atropine was given IM eight minutes post exposure. After ventilation was stopped, the MRTX group started to breath freely and independently, in contrast to the PPV and control groups. Survival Rate in each group:

  • 33% of Control group survived with no ventilatory support
  • 28% of the PPV group survived using an airbag ventilation
  • 100% of the Biphasic ventilation group using the MRTX survived.

Exhibit C

The effect of BCV for acute respiratory failure through the patient of pandemic A (H1N1) influenza infection was examined. BCV (Continuous Negative Mode: CNEP) was used as respiratory management in 4 cases, and BCV (Secretion Clearance Mode: SC) was used as airway clearance in 8 cases. All 4 BCV (CNEP) cases had pneumonitis, respiratory distress and severe hypoxia. In 3 cases using BCV (CNEP), atelectasis was present. BCV (SC) with BCV (CNEP) was used to clear their airway 3 or 4 times a day. The patients recovered without intratracheal intubation.
Overall, BCV was effective for pandemic A (H1N1) influenza. Especially, the direct effects that BCV (CNEP) provided from early respiratory distress, and as a result prevented serious illness. BCV (SC) prevented obstruction of the airways, and also aided patient’s to recover from marked obstructions (plastic bronchitis).
