What is a NICU oscillator?

High-frequency oscillatory ventilation (HFOV) is a lung-protective strategy that can be utilized in the full spectrum of patient populations ranging from neonatal to adults with acute lung injury. HFOV is often utilized as a rescue strategy when conventional mechanical ventilation (CV) has failed.

How does oscillatory ventilation work?

High frequency oscillatory ventilation (HFOV) is a type of mechanical ventilation that uses a constant distending pressure (mean airway pressure [MAP]) with pressure variations oscillating around the MAP at very high rates (up to 900 cycles per minute).

What is Hz on HFOV?

This is the measure of pressure the ventilator uses to push air into the circuit. ΔP (amplitude) creates the wiggle seen in HFOV. Frequency – the rate at which oscillations are delivered. Expressed in hertz where 1 hertz = 60 breaths per minute.

What controls oxygenation on HFOV?

mPaw controls oxygenation This is the main controlling variable of oxygenation. Typically, by setting a high Paw one can achieve maximal lung inflation, and thus maximal gas exchange.

What is the difference between an oscillator and ventilator?

High-frequency oscillation (HFO) ventilation differs from conventional ventilation in that very small breaths are delivered very rapidly (180 to 900 breaths per minute). HFO helps with the opening of collapsed lung tissue by providing constant positive pressure in a person’s airway.

How do you improve ventilation on Hfov?

Check CXR 2 hrs after converting to HFOV, then adjust MAP to achieve optimal lung volume (9-10 ribs expanded). If not oxygenating, increase MAP by 2 cm every hour until oxygenation improves. Adjust Power to keep PaCO2 45-55.

How do you improve ventilation on HFOV?

What is the difference between HFJV and HFOV?

HFOV deliver tidal volumes smaller than the dead space by using a piston or a diaphragm with active inspiration and expiration (Cotten 2001; Courtney 2002;Courtney 2006), whereas HFJV is used in conjunction with CMV and delivers pulses of gas into the trachea with active inspiration and passive expiration (Cotten 2001; …

What is bias flow in HFOV?

During high frequency oscillatory ventilation (HFOV), bias flow is the continuous flow of gas responsible for replenishing oxygen and removing carbon dioxide (CO2) from the patient circuit. Bias flow is usually set at 20 liters per minute (lpm), but many patients require neuromuscular blockade (NMB) at this flow rate.

How do you wean off HFOV?

Weaning

1. First only wean FiO2 until < 0.50-0.60 unless hyper-inflated.
2. Once FiO2 < 0.50-0.60 or hyper-inflated, decrease MAP by 1 cm Q4-8h; if OXYGENATION is lost during weaning then increase MAP by 3-4 cm to restore lung volumes and begin weaning again, but proceed more slowly with decreases in MAP.

What is the basic principle of oscillator?

There are many types of electronic oscillators, but they all operate according to the same basic principle: an oscillator always employs a sensitive amplifier whose output is fed back to the input in phase. Thus, the signal regenerates and sustains itself. This is known as positive feedback.
