Ventilators are commonly known as breathing machines because they support patients to breathe for themselves, or can take over breathing for a patient completely.HFOV was first approved for use in begining of 1991 early intervention in the treatment of neonatal respiratory failure.
The scope of application was broadened in 1995 to include selected pediatric patients failing conventional mechanical ventilation. The ultimate in lung protection by inflating the lung with a continuous distending pressure and superimposing very small pressure and volume swings.
There are over 3000 ventilators in use worldwide.
he next generation of High Frequency Oscillatory Ventilators.
The treatment of acute respiratory failure in adults and large children weighing more than 35 kilograms.
New generation allows the application of continuous distending pressures to recruit and normalize lung architecture while ventilating the patient with near deadspace tidal volumes for the ultimate in low stretch lung protection.
Comparing HFOV and conventional ventilation in an adult patient population with severe ARDS demonstrated that HFOV is both safe and effective and resulted in a 29% relative reduction İhfov safe and effective in improving the refractory hypoxaemia associated with this condition.
• HFOV translate into significantly improved patient outcomes.
HFOV Ventilators of ICU tyes are used when
To protect the airway and lungs if the person is not awake enough, eg after surgery, or if they have had a stroke
If the patient has respiratory (lungs) muscle weakness and they are not strong enough to breathe for themselves
If they have suffered damage to their lungs from an infection or trauma
The use of an ICU ventilator is most often indicated when a patient's natural, spontaneous breathing is deemed inadequate to sustain life. It is also used when a person's breathing is not providing adequate gas exchange during his or her natural breathing cycle. ICU ventilators are essential to modern medicine, but they do not cure underlying medical conditions; however, many people could not survive without them, and physicians and healthcare providers rely on them daily to provide life-saving care.
HFOV used in burn patients with acute respiratory distress syndrome and respiratory failure. Burn patients treated with HFOV in Pediatric Burn Unit also..The hospitals ICU medical staff has experience, with the HFOV in severe burn patients.HFOV has significant, early, and sustained improvement in oxygenation. Earlier institution of HFOV seems to significantly lower rates of barotraumas.
New techniques enabling partitioning
of airway and tissue properties are being developed for measurement of lung mechanics during HFOV.respiratory function High frequency ventilation is a type of mechanical ventilation which utilizes a respiratory rate greater than 4 times the normal value. High frequency ventilation is thought to reduce ventilator-associated lung injury (VALI), especially in the context of ARDS and acute lung injury. This is commonly referred to as lung protective ventilation. Each type has its own unique advantages and disadvantages.
High frequency ventilation may be used alone, or in combination with conventional mechanical ventilation.High frequency oscillatory ventilation is used in neonates and adult patient populations to reduce lung injury, or to prevent further lung injury. HFOV has having both inhalation and exhalation maintained by active pressures. The rates used vary widely depending upon patient size, age, and disease process
