  3. Precautions that would reduce troubles I. Power: • Plug into a grounded AC power with correct voltage receptacle. • Secure the power cord properly. Battery Back up: • Check the battery level before connecting. • Charging should be carried out regularly. • Remember it is for short term use.

  4. II. Gas Source • Preferable to have centralised supply. • If cylinders used, should be full • Spare cylinders should be available. • Gas hoses should be in good condition. • Hoses – not contaminated with grease or oil (combustible) • Availability of compressors should be ensured. • Gases should remaindry and clean.

  5. III. Personnel • Properly trained personnel should only use. • Familiarising staff with operator’s manuel before using on a patient. (One manufacturer’s manual may not exactly match with other brands). • Appropriate monitoring the functioning state of the ventilator while in use.

  6. Contd… • Familiarizing staff with alarm system. • Do not place ventilators in a combustible or explosive environment. • Do not use with flammable anaesthetic agents such as nitrous oxide and ether.

  7. IV Servicing and Testing • Qualified personnel should undertake servicing. • Ventilator housing should not be opened while it is still connected with power. • Follow the specifications mentioned in the service manual. • Use replacement parts supplied by the manufacturer only.

  8. Contd…. • General servicing at regular intervals should be done. • Run the prescribed tests and calibrations before using the ventilator on a patient. • Ensure that the ventilators pass all the tests before putting them in to clinical use.

  9. ALARMS • All ventilators are equipped with visual and audible alarms which notify the user problems.

  10. Points to remember • Never ignore an alarm. • Never mute the alarm on regular basis. • Find out for yourself what alarm is on. • Check the patient. • Silence the alarm.

  11. Act Swiftly • Depending upon the patient’s status and nature of the alarm, act appropriately. • This includes disconnecting the ventilator and connecting another means of ventilation to patient – Bain’s/ Ambu.

  12. Do not forget • The use of an alarm monitoring system does not give absolute assurance of warning for every form of trouble that may occur with the ventilator.

  13. Do not be like this ! But hear the alarm and respond See the problem and Ask if you do not know what to do

  14. Common Troubles and Shooting Ensure Alarm knobs / switches are turned on and functional.

  15. Trouble shooting! THANK YOU FOR YOUR PATIENT HEARING. . . . .
