1
Q

what does high pressure alarm indicates?

A

indicates that there is a high resistance to airflow

2
Q

what does low pressure alarm indicates?

A

indicates that there is a low resistance to airflow

3
Q

main indication of high pressure alarm

A

obstructions

4
Q

main indication of low pressure alarm

A

disconnections

5
Q

3 types of obstructions

A
  • kinks on tube
  • water condensing within the dependent tube
  • mucus secretions along the airway
6
Q

what to do when you see that the tubes are kinked?

A

unkink

7
Q

what to do when you see that the dependent tubes are filled with water?

A

empty the tube or remove the water

8
Q

what to do when the airway is being obstructed with mucus secretions? (before suctioning)

A

change position ( turn-cough-deep breathe)

9
Q

how many times you must do suctioning?

A

as necessary ( do more turning!)

10
Q

2 types of disconnections?

A
  • main tubing disconnected

* oxygen sensor tubing disconnected

11
Q

what to do when the main tubing has been disconnected?

A

reconnect the main tube

12
Q

what is the main function of the oxygen sensor tubing?

A
  • senses FiO2 (The ratio of partial pressure arterial oxygen and fraction of inspired oxygen, sometimes called the Carrico index, is a comparison between the oxygen level in the blood and the oxygen concentration that is breathed.)
  • measures FiO2 (O2 being delivered)
13
Q

ABG reading: when the ventilator setting is too high (over ventilating)

A

Respiratory Alkalosis

14
Q

ABG reading: when the ventilator setting is too low (under ventilating)

A

Respiratory Acidosis

15
Q

Situation: The client is on a ventilator machine then doctor ordered: weaning from ventilation. The next day, ABG result is: Respiratory acidosis (under ventilating). What should the nurse do?

a. follow the doctor’s order
b. call Respiratory Therapist
c. hold the order and call the doctor
d. begin to decrease the ventilator settings

A

c. hold the order and call the doctor

the client is already under ventilating and Weaning from mechanical ventilation is the process of reducing ventilatory support, ultimately resulting in a patient breathing spontaneously and being extubated. however the ABG result on the next day shows Respiratory acidosis which means the client is experiencing under ventilation, so we need to hold the order and call the doctor for further instructions. if only the ABG result showed Respiratory alkalosis (over ventilating) then we can proceed to follow the doctor’s order.
