Hi, My dad is chronic Asthamatic. He is also having high BP problem for which he is taking regular medicine. For Asthma he is taking maxiflo 250 inhaler. From last few days he has been struggling to breath properly and we can hear a whizzing sound. We have nebuliser machine however don't know which nebuliser should be given. Can you suggest me a nebuliser which can go well at his age and BP condition also. Additional any medicine if you can suggest given inhaler is a very temporary relief Thanks
