The recommended initial ventilator settings for an adult typically include a tidal volume of 6-8 ml/kg of ideal body weight and a respiratory rate of 12-20 breaths per minute. For a 160-lb (approximately 73 kg) adult, a tidal volume of 500 ml (close to 6-8 ml/kg) and a rate of 12 breaths/min falls within these guidelines, making it a suitable choice for someone with chronic obstructive pulmonary disease (COPD) to ensure adequate ventilation without causing overdistension or rapid breathing that could lead to increased work of breathing or air trapping.
