Question

volun ntilated by a tank of gas, the technique is known as intermittent positive pressure breathing te expiration. yng this term, explain how this technique inflates the lungs for inspiration and deflates the per the lungs for 11. Calculate these values for the spirogram shown here. Be sure to correct your values to BTPS (use a BTPS value of 1.1n o ion *^^ 5,500 mL nute era 3,200 mL 2,400 mL 950 mL (a) tidal volume (b) inspiratory capacity (c) expiratory reserve volume (d) vital capacity mL mL mL mL 12. Calculate the FEV, value for the spirogram shown here. 6,200 mL

Explanation / Answer

Please find the answers below:

Answer 1:

Part a: Tidal volume is the volume of gas exchanged across the lungs to support life, i.e. 2400 ml.

Part b: Inspiratory capacity represents the maximum volume of gas inspired by the lungs i.e. 5500 ml.

Part c: Expiratory reserve volume is the maximum volume of gas expired by lungs in one cycle i.e. 950 ml.

Part d: Vital capacity represents the volume of gas inspired and expired during maximum inhalation and exhalation i.e. 5500-950 = 4550 ml.
