Staff variables
|
1. Do you think that a high alarm frequency during the work shift leads to latency in response time to the alarm or a decreased attention to that?

• No
|
10. If you answered yes, how long are they disabled on average?
• Less than 5 minutes
• From 5 to 10 minutes
• More than 10 minutes
|
11. During the execution of the assistance maneuvers, does the healthcare professional use supplemental oxygen?
• Yes
• No
|
