As R aw increases, the patient commonly manifests1. a decreased ventilatory rate.2. an increased tidal volume.3. a decreased tidal volume.4. an increased ventilatory rate.A. 1 onlyB. 2 onlyC. 1 and 2 onlyD. 3 and 4 only

Summary Introduction

Introduction:

The airway resistance Raw is described as the pressure difference between the mouth and the alveoli divided by the air flow rate. In simple terms, the rate at which a specific volume of gas passes through the bronchioles is a function of pressure gradient and the obstruction of the gas flow generated by airways.

Explanation

Justification for the correct answer:

Option C states that t 1 and 2 only. The patient usually manifests a reduced ventilator rate and an enhanced tidal volume as the Raw increases. The patient characteristically assumes a slow rate of ventilation and a large tidal volume per breath to counterbalance the increase in Raw. By reducing the rate of ventilation, and deep breathing, the minute volume of the patient will remain normal.

Justification for the incorrect answers:

Option (a) is given as 1 only...
