Wanda when my husband started his tube feedings the rate started at 80ml/hr. Gradually increase the rate by 20ml. every 4 hours as long as he is tolerating it to a maximum of 120ml/hr. We ran the feed through the night so he didn't notice the length of time it was running so much. The dietician likely has told you how many cans a day is optimal for your husband. He should also have some water during the day too. I used to just let that run free of the pump. I know your husband will feel much better getting proper nu trition and it will certainly help his healing. Also if he is taking the feeds while in bed he should be propped up to a 30 degree angle or sleep in a recliner chair.PM me if any further questions.
