Current Project

It is common to use additional oxygen therapy in acute care hospitals and in long-term care facilities. It is problematic as well as dangerous to deliver oxygen at an improper amount. There are clinical situations in which oxygen is needed, but nasal cannula has different properties, causing it to be difficult to determine the percentage of inspired oxygen. This study has three different parts:

1)This study uses our research group's work on in vitro benchtop testing methods for medical gas delivery devices that provide oxygen to newborns and infants. Through an in vitro method, we evaluate low-flow oxygen therapy in neonates and infants. A novel correlation is established to predict the fraction of oxygen in trachea (FiO2), accounting for variability between subjects and between breaths.

2) a realistic upper airway replica of an adult is used to simulate various breathing patterns. We combine FiO2 values measured in an adult replica with previously determined values measured in neonates to establish a single relationship for FiO2, based on nasal cannula oxygen flow rate and inhaled air (dependent on tidal volume (Vt) and inhalation time(ti)), that applies to all age groups and nasal cannula flow rates within the range of low flow oxygen delivery.

3)A controlling system will be developed with the goal of improving automatic oxygen delivery. FiO2 is determined by applying the derived equations from the previous parts of the study and calculated FiO2 values allow prediction of the change of oxygen saturation in blood(SpO2) within the next few minutes.

After graduation researches    Project of tunnel ventilation

My groupmates and I did a project for ventilation of Taloon Tunnels, which connect Tehran to North in Iran, in order to find the best combination of axial fans and jet fans with and without considering fire and traffic. In fire condition, we tried to provide a ventilation system to make balance at the both sides of fire so as to prevent smoke propagation.

In another study, at the first step, semi-transverse ventilation system was evaluated by considering the effect of pressurizing the service tunnel. Secondly, the possibility of ingress of air from the main tunnel in emergency condition into service tunnel or another main tunnel was investigated.
