Flashcards in Lecture 3 Deck (17):
1

What is Hypoxaemia?

A lack of oxygen-rich blood

2

What does Hypoxaemia result in?

Less efficient anaerobic metabolism and compromised cellular function

3

Early Signs of Hypoxia

From organs at most risk (heart/brain) Confusion, headache, reduced consciousness, tachyarrhythmia or chest pain

4

Benefits of Laryngeal Mask Airway (LMA):

Rapid/easy insertion, more efficient than facemask, avoids need for laryngoscopy and full intubation

5

When would advanced airway management be used?

Reduced level of consciousness, respiratory failure requiring additional O2 support + +ve pressure support + active removal of sputum

6

Why is pressure placed on cricoid cartilage during insertion?

Reduces risk of regurgitation and aspiration

7

Advantages to tracheal Intubation?

Allows upto 100% O2 ventilation, isolates airway preventing aspiration, allows suctioning of airway, alternate route for drug administration

8

What is a tracheostomy?

A surgical opening in the anterior wall of the trachea to facilitate ventilation

9

What are the 2 basic types of Tracheostomies?

Surgical and Percutaneous

10

Indications for a tracheostomy?

Upper airway obstructions, respiratory insufficiency, sputum retention, surgical procedures, neuromuscular disorders, Long term ventilation

11

What does CPAP stand for?

Continuous Positive Airway Pressure

12

What does BiPAP stand for?

Bilevel Positive Airway Pressure

13

Clinical criteria for Intubation and ventilation?

Inability to protect airway, inadequate breathing pattern, inability to sustain adequate oxegen for metabolic demands, Hypercarbia

14

Whats hypercarbia?

Acute rise in PCO2 >50mmHg with acidosis pH<7.3

15

What is tidal volume? And Minute volume?

The volume of each breath. And tidal volume x RR over the minute

16

What is Airway pressure peak?

The max pressure measured in patient’s airway

17

What is Inspiratory trigger level?

The amount of effort needed by the pt to initiate a breath from the patient
