How to get better in Intubation!!

Help! Emergency Medicine PGY3 here !

How can I be confident while handling intubation? In our institution, we residents are more in number and procedures are also provided according to hierarchy. So, one don't end up getting much hands on with procedure. Now that I'm in final year..I'm getting the chances for intubation but I'm not at all confident. 70% of time I need someone with me who can take over if I am not able to do it..

Today, we had a sick case who came with cardiac arrest. I was standing at airway ready to intubate but my HOD came over and did it himself ( he never does ..I'm glad he did) Maybe coz patient was young and no one wanted to take a chance.

But I feel sad and incompetent..

How to waiver off these feeling and focus on what's important and get better with this.

As an emergency physician ..this is what I should be knowing best!! Kindly help.
