    • Make the ramp look cleaner and more aesthetically pleasing

      • will smooth out sharp corners

    • Have the cover enclose the entire ramp but leave the hinges accessible

    • Laryngoscope blade looks great and has good visualization and tracks well

    • Tunnel is still a little wide; taper the entrance for easier removal from mouth and prevent it from getting caught in the lip

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

• • Comments on report draft from Team 10

Risks and Areas of Concern

• • Hinges are difficult to move still

    • Can be fixed by taking apart the hinge and removing springs from the inside but due to multiple attempts at undoing the screw, it is starting to strip

    • Other option is adding lubricant
