Variable<o:p></o:p>	Dog<o:p></o:p>	Cat<o:p></o:p>	Action<o:p></o:p>
Heart Rate<o:p></o:p>	50 – 120¹^<o:p></o:p>	120 – 200¹^<o:p></o:p>	High: check depth of anaesthesia/repeat opiates due Low: Check depth of anaesthesia. And lighten as required / drugs to increase HR (check with VS)
Resp Rate<o:p></o:p>	10 – 20	15 – 25	<o:p> </o:p>
Temperature (ºC)<o:p></o:p>	37.5 – 39.2	37.8 – 39.2	Hyper: Remove external heat sources and attept to cool (fans, damp towels etc) Hypo: use external heat sources, Hot hands², heated flushing fluids, bubble wrap, foil blankets<o:p></o:p>
Arterial BP (mmHG)<o:p></o:p>	<o:p> </o:p>	<o:p> </o:p>	<o:p> </o:p>
Systolic<o:p></o:p>	110 - 190	120 – 170	<80: using Doppler (see under mean)

Mean<o:p></o:p>	70 – 100³^<o:p></o:p>	60 – 90³^<o:p></o:p>	<60: reduce depth of anaesthesia. Bolus of crystalloid (10mls/kg), if no better bolus of colloid (5mls/kg up to max of 20ml/kg/24hr) >100: check depth of anaesthesia, pain response.
Saturation %<o:p></o:p>	> 95	> 95	<95: check sensor has not constricted tongue
PaCO₂ mmHG<o:p></o:p>	28 – 60	28 - 45	>60: IPPV, possibility of rebreathing CO₂ and check depth of anaesthesia <28: IPPV check ET tube, connections and rebreathing bag

<o:p> </o:p>

Look for trends rather than one off readings and inform VS if concerned

Can be higher following induction and then drop
Use 500ml saline fluid bags and heat in microwave rather than gloves filled with hot water, these can be reused and less likely to pop.
Under ACP and Isoflurane MABP is lower than conscious animals
