Question

A 5'6'' female patient is placed on mechanical ventilation.

Following the ideal body weight equation, which tidal volume range
is most appropriate for this patient using 6-8
mL/kg?
a) 306 - 613
b) 322

Answer 1

The appropriate tidal volume for a 5'6'' female on mechanical ventilation, using the 6-8 mL/kg guideline based on ideal body weight, ranges from 355.8 mL to 474.4 mL.

Step-by-step explanation:

To determine the appropriate tidal volume for a 5'6'' female patient on mechanical ventilation, we first need to calculate her ideal body weight (IBW), which is used to calculate tidal volumes in a clinical setting. For females, the IBW formula (in kg) is 45.5 + 2.3 for each inch over 5 feet. For a 5'6'' female:

IBW = 45.5 kg + 2.3 kg × 6 inches = 45.5 kg + 13.8 kg = 59.3 kg

Next, we apply the tidal volume range of 6-8 mL/kg to the IBW. Therefore, the calculated tidal volumes are:

6 mL/kg × 59.3 kg = 355.8 mL8 mL/kg × 59.3 kg = 474.4 mL

The most appropriate tidal volume range for this patient would be between 355.8 mL and 474.4 mL.
