These datas are collected in our hospital last 3 months from August to October. On this data analysis we found 33 critical alerts in last 3 months.

These datas (critical alerts) are differentiated under 5 columns,

  1. Descriptive statistics
  2. Age range
  3. Sex
  4. Time
  5. Month

1). Descriptive statistics

Totally we used this lifesigns patches for 31 patients.

  1. Number-Totally we found 33 critical alerts.
  2. Minimum age we used -21 years.
  3. Maximum age we used -90 years.
  4. Mean of this statistics is 64.64.
  5. Standard deviations are 20.720.

2. Age range

Age ranges are divided into 4 columns

  1. 20-40 age group – Totally 5 critical alerts are found in this age group (Hyperthermia -1, Tachycardia -4).
  2. 41-60 age group – 5 critical alerts are found in this age group (Hypertension-1, Tachycardia -4)
  3. 60-80 age group – 11 critical alerts are found in this age group (Hypertension -11).
  4. Above 80 age group – High alerts are noted in this aged group, totally 12 critical alerts are found in this group (Bradycardia-6, Hyperthermia-2, Hypertension-2, Tachycardia-2).

For example, if patient who stepping down from ICU to ward (because they need close vitals monitoring).

Totally 33 critical alerts in these 3 months.

Out of 33 critical alerts,

  1. Bradycardia – 6
  2. Hypertension – 14
  3. Hyperthermia – 3
  4. Tachycardia – 10

Advantages of lifesigns patch:
