pass. This is because of low atmospheric pressure,
which facilitates optimum filling of the impaired lungs
with wet atmospheric gases. Gusts induced random
non generalised variation inside room, whereas outside
facilitated a generalised heightened expiration (Table
1,
column e). These clinical observations and findings
are for the first time being related to atmospheric
conditions and severe weather events.

Figure 1~Figure 3 are graphs produced during lung
function test done by a spirometer (with graph print
out facility). These are of another congenital asthma
patient of adolescent age (16 yrs), male, who is also
acutely asthmatic. A resident of Vishakhapatnam

°41'18?N//83°13'07.5?E) port town too is in the
direct path of cyclone pass. He is entirely dependent
on inhalers through the day and even requires

stable and a good representative candidate. O-Y
represents the time component i.e. 1 breath cycle
comprised of inspiration and expiration ~2 seconds.
O-X represents volume in milliliter. The isolated
graph was scanned and redrawn {for prominence, sans
clutter} via computer tracing technique using Coral
Draw soft ware. Figure 1 is that of unaided, at 40
meters above MSL, when the atmospheric pressure
was of the order 1 004 hPa. The lower half represents
inhalation volume and the upper half denotes
expiration volume. Figure 2 is that of post 2 continuous
puffs of Salbutamol+Beclomethasone dipropionate

g (i.e. medically aided) at near similar atmospheric
conditions (test done on another day). Figure 3 is that

We
may note that, under atmospheric low conditions, the
lungs of a asthma patient not only expirates more, but
also inspirates (deflates) more. It is relevant to relate
here, that, the OTBM (Weatherhall et al., 1983) and as
well Harrison (Kasper et al., 2005) states, that, the
