Airway Flashcards
1
Q
Indications for suctioning
A
- High PEEP greater than 10cm H20
- High MAP greater than 20cm H20
- Long I-time greater than 1.5s
- High Fi02 greater than 60
- Frequent suctioning more than 6xdays
- Hemodynamic instability associated with ventilator disconnection
- Respiratory Infections requiring airborne or droplet precautions
- Patients receiving inhaled gas mixtures (Nitric, Heliox)
- Inability to generate an effective cough
- Deterioration of Pulse Ox or ABG values
- Increased PIP with volume ventilation
- Decrease in Vt with pressure ventilation
- Visible secretions
- Acute respiratory distress
- Suspected aspiration
2
Q
Hazards of suctioning
A
- Hypoxemia (Preoxygenate)
- Cardiac Dysrhythmias (brady w/vagal nerve or tachy due to hypoxemia)
- Hypotension
- Hypertension
- Atelectasis
- Mucosal trauma (Use shallow suctioning method)
- Increased intracranial pressure (ICP)
- Bacterial colonization of lower airway
3
Q
Cuff Pressures
A
20 to 30 cm
4
Q
Indications for OPA & NPA
A
- Airway obstruction by the tongue (OPA)
- Help facilitate suctioning (NPA)
- Resistance during bagging
5
Q
Airway of choice
A
Endotracheal Tubes (ETT)
6
Q
Endobronchial intubation
A
- Equal breath sounds
- Tube depth (21-23cm Male/19-21cm Female)
- Symmetrical chest movement
- Treat by pulling back 1-2cm. Get chest xray
7
Q
Colorimetric/ Capnograph
A
Gold is good
Rapid increase in C02 levels
8
Q
Cuff Leaks
A
Low-Pressure Alarms Set 5-10 below PIP
Decreased breath sounds
Airflow felt at the mouth
9
