Patient at inspiration. V.A.D. above C.A.J. Example of why the box needs to be as long as it is. |

Example of why Sweet Spot™ needs to be this wide. |

Left-sided access - The catheter can still be very vertical in S.V.C and R.A. |
Figure - 12
C.A.J. ≈ 4-5 cm below carina - Most patients, most inspiratory CXR's. |

Often, the cavo-atrial junction can be approximated accurately as about 5 cm below the carina |
