1. A modular external defibrillator system for treating a patient, comprising:
a base containing a display and an external defibrillator module configured to deliver a defibrillation shock to the patient;
a first pod operable when separated from the base, the first pod having a first patient parameter module and connectable to the patient to collect first patient data related to at least a first patient vital sign, the first pod capable of wirelessly transmitting the first patient data to the base; and
a second pod operable when separated from the base, the second pod having a second patient parameter module and connectable to the patient to collect second patient data related to at least a second patient vital sign independent from the first vital sign, the second pod capable of wirelessly transmitting the second patient data to the base,
in which, when one of the first or the second patient data is transmitted to the base, the base is configured to display an aspect of the transmitted one of the first or the second patient data;
wherein the system is configured to select one of the first or the second pods over the other to transmit to the base the patient data the selected pod collects;
wherein the selection of the selected pod is based on a comparison of the first patient data with the second patient data for detecting an abnormality in either the first patient data or the second patient data.
2. The external defibrillator system of claim 1 , in which
the external defibrillator module is configured to deliver the defibrillation shock based on the one of the first or the second patient data transmitted to the base.
3. The external defibrillator system of claim 1 , in which
the first pod contains an interpretive algorithm to analyze a patient condition based on the first patient data.
4. The external defibrillator system of claim 1 , in which
while the base is receiving the first patient data, the base is configured to sense a nearby presence of the second pod, and provide an alert in response to sensing the second pod.
5. The external defibrillator system of claim 1 , in which
the one of the first or the second patient data that is transmitted to the base is encrypted.
6. The external defibrillator system of claim 1 , in which
the base is configured to control which of the first or the second pods is selected over the other.
7. The external defibrillator system of claim 1 , in which
a unique pod identifier is transmitted from the selected pod to the base.
8. The external defibrillator system of claim 1 , in which
the selected pod is configured to provide an indication when prompted by the base to confirm that the selected pod has been selected over the other pod.
9. The external defibrillator system of claim 1 , in which, when the base and the selected pod are communicating wirelessly over a link, if the link degrades, one of the base or the selected pod is configured to provide an alert.
10. The external defibrillator system of claim 1 , in which, when the base and the selected pod are communicating wirelessly over a link, if the link degrades, less patient data is carried to the base.
11. The external defibrillator system of claim 1 , in which, when the base and the selected pod are communicating wirelessly over a link, if the link is lost, the system is configured to output an alarm.
12. The external defibrillator system of claim 11 , in which
if the link is not reestablished within a preset time period after the alarm is output, the selected pod configured to enter a sleep mode.
13. A method for a modular external defibrillator system for treating a patient, the system including: a base containing a display and an external defibrillator module configured to deliver a defibrillation shock to the patient and to control which of the first or the second pods is selected over the other, wherein the selection is made by comparing the first patient data with the second patient data for detecting an abnormality in either the first patient data or the second patient data, a first pod operable when separated from the base, the first pod having a first patient parameter module and connectable to the patient to collect first patient data related to at least a first patient vital sign, the first pod capable of wirelessly transmitting the first patient data to the base, and a second pod operable when separated from the base, the second pod having a patient parameter module and connectable to the patient to collect second patient data related to at least a second patient vital sign independent from the first vital sign, the second pod capable of wirelessly transmitting the second patient data to the base, the method comprising:
selecting one of the first or the second pods over the other;
establishing a communications link between the base and the selected pod, in which the one of the first or the second patient data collected by the selected pods is transmitted wirelessly to the base; and
displaying at the display an aspect of the transmitted one of the first or the second patient data.
14. The method of claim 13 , further comprising:
delivering a defibrillation shock based on the one of the first or the second patient data transmitted to the base.
15. The method of claim 13 , further comprising:
analyzing a patient condition based on an interpretive algorithm in the selected pod and the patient data collected by the selected pod.
16. The method of claim 13 , further comprising: while the base has the communications link established with the selected pod, sensing a nearby presence of the second pod, and providing an alert in response to sensing the second pod.
17. The method of claim 13 , in which
the one of the first or the second patient data that is transmitted to the base is encrypted.
18. The method of claim 13 , in which
the selection is made by electrically directly connecting the one of the first or the second pods to the base.
19. The method of claim 13 , in which
a unique pod identifier is carried from the selected pod to the base.
20. The method of claim 13 , in which
the selected pod provides an indication when prompted by the base to confirm that the selected pod has been selected over the other pod.
21. The method of claim 13 , in which
if the link degrades, one of the base and the selected pod provides an alert.
22. The method of claim 13 , in which
if the link degrades, less patient data is carried to the base.
23. The method of claim 13 , in which
if the link is lost, an alarm is output.
24. The method of claim 23 , in which
if the link is not reestablished within a preset time period after the alarm is output, the selected pod enters a sleep mode.
