6
Q
Signs of Respiratory Arrest
A
- Stopping of respiratory efforts
- Pulse oximetry rapidly falls
- MM color goes towards cyanosis
7
Q
Respiratory Arrest Treatment
A

Q
Cardiopulmonary Resuscitation
A
Initiated when sudden apnea occurs and the heart action is not enough for adequate circulation

12
Q
Causes for Airway Obstructions
A
- Accumulation of secretions
- Soft tissue obstruction
- Collapsed trachea
- Laryngospasms
- Mechanical means
13
Q
Airway Obstruction
Mechanical Causes
A
- Dislodged ET tube
