The purpose of this study is to investigate and measure the metabolic and heartrate changes involved in hairwashing carried out by nurses on subjects bending over a wash basin. Subjects were completely passive during hairwashing. Nine healthy females between the ages of 19-20 were chosen as subjects. The main results are as follows. 1) During hairwashing the 0_2 consumption rate of subjects increased 20% above the rest level. 2) Two peaks in O_2 consumption and expiration volume were noted. The first occurred exactly one minute after subjects rose from a lying position on a bed and took eight steps to the wash basin. Subjects also showed nervous anticipation. The second peak occurred eight minutes after the experiment's beginning. Hairwashing ceased after 7.4 minutes, so this large increase may be attributable to an oxygen debt incurred by bending over. 3) The relative metabolic rate (R.M.R.) was 0.5. This is about two and half times the rate found by hairwashing in a supine position. 4) Twenty seconds after the experiment began, subject's heart rates were 47% above the rest rate. Two minutes after the experiment began, when subjects had been washed their hair in the bending position, their heart rates were near the rest level. 5) Taking the difference between the rest level and the maximum level as 100%, we found that the heart rate recovered by 89.2% 40 seconds after the cessation of hairwashing, and reached the rest level 1 minute 20 seconds. This latter point was taken as the stop point of the experiment. These studies show that hairwashing of subjects in the bending position by nurses requires little effort from subjects. Subjects suffering from specific diseases would require more care. |
