First, the bad news: newborns eat and sleep on 3-4 hour cycles. By the age of three months, however, newborns can hold enough food to sleep for longer, perhaps 5-6 hours at a stretch. The key is to make sure everythingâs just right at bedtime, and that your babyâs eaten until full and content. When your baby goes to bed for the night, you go to bed!
1 After urine starts to flow, gently push in the catheter about 2 more inches, or to the Y connector. (Younger boys will push in the catheter only about 1 inch more at this point.) 2  Let the urine drain into the toilet or special container.  When urine stops, slowly remove the catheter.
The procedure, known as right heart catheterization, may be performed with or without the use of fluoroscopy. The typical PA catheter is 110 cm long and has four lumensâthe distal, proximal, thermistor, and inflation lumenâeach of which leads to a specific port. (Some PA catheters have a second proximal lumen and port.) The catheter is marked incrementally with black bands that indicate the length of insertion.
