A

When the physician orders to back off the ventilator support.

75
Q

Ventilator Modes: What is Pressure Support Volume (PSV)?

A

Patient is doing a lot of work of breathing by themselves, but ventilator is providing some pressure to keep alveoli open.

76
Q

Ventilator Settings - Ventilator Mode: What is this usually set to

A

Unless patient is starting to be weaned, this will be CMV, or Assist Control

77
Q

Ventilator Settings - Ventilator Mode: You want to see if this is doing what for patient?

A

All the work for the patient or if they are starting to be weaned off of it

5-15

88
Q

Ventilator Settings - Peep: What happesn when you get above 15

A

You see issues with baro trauma within lungs. So much pressure can be caused that can cause them to have a pneumothorax and collapse part of lung.

89
Q

91
Q

Noninvasive Positive-Pressure Ventilation: CPAP is usually for who

A

Sleep Apnea,

92
Q

Noninvasive Positive-Pressure Ventilation: How does a bi-PAP work?

A

Instead of airway being open by continuous air, gives a certain pressure on inspiration and another pressure on expiration.

93
Q

Noninvasive Positive-Pressure Ventilation: What type of patient would use Bi-PAP?

A

Those with COPD, usually at night. Sometimes those with HF, as it eases breathing and enhances gas exchange. Pulmonary Edema too.

94
Q

Noninvasive Positive-Pressure Ventilation: How does bi-PAP help with pulmonary edema?

A

Helps open the alveoli and push the fluid out of there. Lasix may also be prescribed.

95
Q

Noninvasive Positive-Pressure Ventilation: What must you be careful of with bi-PAP?

A

Putting a patient on bi-PAP if they have AMS. They may start retaining CO2 because they don’t accept t`he inflow of air.

96
