How to use ventilator with Type of modes

The ventilator provides complete life support for the patient with post-surgical and ARDS etc. Non-invasive ventilation intended for the use of positive airway pressure ventilation. see more for modes of ventilation in the post how to use ventilator

Minimum tidal volume ventilation delivered  shall be equal to or greater than the 20 ml for adults patients and 2 ml for the infants /neonates

Check the ventilator with the resuscitation bag using the PEEPand high concentration oxygen.

Scope: Patients with respiratory distress are supported with ventilatory support to maintain optimal blood oxygen levels.

How to use ventilator: Prechecking and Precautions

Do not use the exhaust port of the expiratory valve for the spirometry.

Do not use any liquid items on the Hamilton ventilator, no spillage or liquid item on the ventilator console

Avoid using flammable agents or material on the ventilator setup.

Don’t use the contaminated items, oil or grease on the ventilator.ventilator

Highly compressed oxygen together with flammable sources could lead to a spontaneous explosion.

Do not use the high-pressure hose for the ventilator pipelines and the gas hoses

Do not use the tubing with antistatic or electrically conducted tubing

In case of fire, stop the ventilation and disconnect all the accessories and disconnect from the electric circuit.

Ventilation safe protocol

Preoperational test

If the test fails

Do it again with the checking of the connection and supply

Again if fails call the service engineer

(S)CMV +/APVCMV-          synchronized controlled mandatory ventilation

SIMV +/APV SIMV         – synchronized intermittent mandatory ventilation

Volume modes(adaptive pressure )

Combination of the pressure and volume targeted ventilation

Pre Procedure:

Informed consent Decision to give ventilatory support is based on parameters which may include:

Arterial blood gas (ABG)

Chest X-ray

Clinical Status Ventilator connected to test lung Ventilatory parameters are set Other requirements for ventilatory support are primed as per patient condition:

Ambu bag with oxygen connection

Appropriate size endotracheal tubes

Laryngoscope

Suction apparatus

Cardiac/ critical care monitor

Pulse Oximetry monitored continuously. During Procedure: Patient sedated and paralyzed if necessary Intubation performed as per the clinical condition of the baby and under strict aseptic condition. The position of the tube checked clinical/chest x-ray Cuff inflated in appropriate cases.

Cuff pressure maintained within 25 to 30 cm of H2O Tubes are fixed to the body of the baby with plaster. Patient connected to the ventilator and parameters rechecked. Saturation monitored using a pulse oximeter. Vitals monitored continuously Suctioning performed periodically

Post Procedure: Once the patient stabilized, ventilatory requirements weaned Extubation planned based on:

Clinical indicators

Ventilatory parameters

ABG

Respiratory indices

Modes in Ventilator

Pressure modes –conventional pressure-controlled modes of the ventilation

PCV +             pressure-controlled ventilation

PSIMV+          pressure controlled synchronized intermittent ventilation

SPONT            spontaneous pressure supported ventilation

CPAP               controlled positive airway pressure

DUO PAP        dual positive airway pressure

APRV              airway pressure release ventilation

ASV                Adaptive support ventilation ( this is only for the adult’s patients )

Non-invasive ventilation modes

NIV Non-invasive ventilation

NIV ST Non-invasive ventilation  spontaneous

n CPAP PS    neonatal modes nasal continuous positive airway pressure

Pressure in cmh2o

m bar or hPa

1 m bar =1 hPa =1.016 cm h2o
