I was completing the patient leg of the flight; delivering the patient to University Hospital under night vision goggles. I was following the GPS guidance information and didn't identify the hospital; subsequently flying past the hospital on the left side of the aircraft by one mile (airspeed approximately 90 KTS). I asked the med crew if they had the hospital in sight and the left side crew member said he had it behind the aircraft. I made a right hand turn to return to the hospital and in the process; I may have flown into the Class D airspace for ZZZ International Airport. I had the Tower frequency in the VHF radio but my pin selector switch was down inadvertently so I am not aware if ZZZ Tower tried to make contact. I placed my pin switch up at that moment; but didn't hear any traffic pertaining to my flight. I had the appropriate squawk code assigned to my aircraft in the transponder. I continued the flight to the University Hospital with the intent to contact ATC once on the ground; but was unable to find a good telephone number.In the future when flying night vision goggles over a highly lit up congested area; it may be easier to identify a hospital unaided. I have flown into this hospital using night vision goggles in the past; but in this circumstance; it was from a direction that I was not familiar with. Better crew coordination between the experienced medical crew and myself could have helped greatly. Medical crew thought I had the hospital in site and that I was making an orbit to align myself with prevailing winds; but did not state that we overflew the hospital until I asked if they had the hospital in site. Even though I had no intention of flying into Class D airspace; an advisory call to Tower while inbound would have made this situation nonexistent as they would have known of my intentions.
Bell-407 pilot initially missed sighting the destination hospital while utilizing GPS and night vision goggles in a well-lit city environment. Pilot may have also inadvertantly infringed on nearby Class D airspace.
